Talksign builds real-time, bidirectional translation between spoken and sign languages. Because that work touches healthcare conversations, classrooms, workplaces, and public services, trust is not a feature we add at the end. It is the foundation everything else stands on. This part explains how we protect data, how we build our AI responsibly, how we meet our regulatory obligations, and how the Deaf community holds us accountable.
1.1 Security
We design Talksign so that the most sensitive part of any conversation never has to leave the device it happens on.
On-device by default
Core translation runs on-device wherever the hardware allows. Speech recognition, sign recognition, and avatar rendering can operate locally, which means a live conversation does not require a round trip to our servers. This keeps latency low, keeps communication available in low-connectivity environments, and keeps private conversations private.
No conversation retention
We do not retain the content of user conversations. Translations are processed and discarded. We do not build a profile of what you said or signed, and we never sell user data. When processing does occur in the cloud, it is transient and is not stored after the translation is returned.
Encryption
| Control | How we apply it |
|---|---|
| Data in transit | All API and application traffic is encrypted using TLS 1.2 or higher. |
| Data at rest | Account and configuration data is encrypted at rest using industry-standard AES-256. |
| Key management | Keys are managed through our cloud provider's managed key service with restricted, audited access. |
Access control
-
Access to production systems follows least-privilege principles and is restricted to authorized engineers.
-
Administrative access requires multi-factor authentication.
-
Access is logged, and credentials are rotated and revocable through our developer dashboard for API customers.
Reliability
We publish uptime commitments in our service agreements: a 99.5% uptime SLA on Premium and Business plans, and a 99.9% uptime SLA for Enterprise customers, who also receive a dedicated support engineer.
Responsible disclosure
If you believe you have found a security vulnerability, we want to hear from you. Please contact security@talksign.co so we can investigate and respond. We do not pursue good-faith security researchers who follow responsible disclosure practices.
1.2 Privacy
Our privacy posture is simple to state: we collect as little as we can, we keep it for as short a time as we can, and we never treat user conversations as a product. Full detail is in Part 3, the Privacy Policy.
What we collect
| Category | Detail |
|---|---|
| Conversation content | Processed in real time and not retained. |
| Account data | Email, plan tier, and billing information needed to operate your account. |
| Usage logs | For API customers, request history and credit consumption with 30-day retention, used for billing and abuse prevention. |
Your rights
We support the rights granted under the UK GDPR and equivalent frameworks, including the right to access, correct, export, and delete your personal data. Requests can be made to privacy@talksign.co. Because we do not retain conversation content, there is no historical record of your translations to expose, sell, or breach.
1.3 Responsible AI and Ethics
Translating sign language is not a neutral technical problem. Get it wrong and you misrepresent a person in a hospital, a courtroom, or a job interview. We treat that responsibility seriously.
Built with, not for
Our guiding principle is that we build with Deaf communities, not for them. Deaf users, educators, and linguists are involved in design and evaluation rather than consulted after the fact. We co-create our datasets with Deaf communities, educators, and researchers, designed to be transparent, representative, and accountable.
Accuracy and honesty about limits
-
We publish our model performance rather than hiding it, and report progress openly as models improve.
-
We are clear that automated translation is an aid, not a replacement for a qualified human interpreter in high-stakes legal or medical settings where a human is required by law or by the user's preference.
-
Our technical approach is grounded in published, peer-reviewable research (Speak2Sign3D, arXiv:2507.06530).
Fairness and bias reduction
Sign languages are not monolithic. We invest in regional and indigenous sign language variants, source voice and accent data across diverse global dialects, and run audits, bias reduction, and red-teaming to reduce the risk that our models work well for some communities and poorly for others.
1.4 Compliance
Talksign is built to help organizations meet their accessibility obligations, and we hold ourselves to the same standards we require of our customers.
| Framework | Relevance |
|---|---|
| UK GDPR / Data Protection Act 2018 | Governs how we handle personal data for UK and EU users. |
| European Accessibility Act (2025) | Drives accessible digital service requirements we are designed to support. |
| UK Equality Act 2010 | Underpins reasonable-adjustment obligations our platform helps organizations meet. |
| ADA digital accessibility | Supports US institutional compliance for accessible communication. |
Intellectual property
Talksign is UK-incorporated. Our core translation system holds an accepted Nigerian patent (NG/PT/NC/O/2026/21520), and our proprietary models are trained on co-designed datasets rather than scraped or off-the-shelf data, which supports both our defensibility and our ethical sourcing commitments.
1.5 Governance
Good intentions are not a governance model. We have put structures in place so that accountability to the Deaf community is built into how the company is run, not left to goodwill.
Community representation
We maintain a governance principle requiring at least 30% Deaf or hard-of-hearing representation on our advisory board. This ensures the people most affected by our technology have a formal, standing voice in how it is built and deployed.
Data and AI governance
-
Ethical data sourcing. Datasets are co-created and documented, with attention to consent and representation.
-
Model evaluation. Models are evaluated for accuracy and bias before and after release, with results reported openly.
-
Privacy by design. On-device processing and no-retention defaults are architectural decisions, not optional settings.
-
Open collaboration. We engage with universities and NGOs to advance open-access datasets and responsible AI development.

Terms of Service
Effective date: July 1,2026 | Last updated: 16 June 2026
These Terms of Service (the “Terms”) govern your access to and use of the websites, applications, and services provided by Talksign Ltd (“Talksign”, “we”, “us”, or “our”), a company incorporated in England and Wales with company number 17060416 and registered office at 190 Holliday Street, Birmingham B1 1FD (collectively, the “Services”). By creating an account, accessing, or using the Services, you agree to be bound by these Terms. If you do not agree, you may not use the Services.
If you are an enterprise or educational customer, the Talksign Data Processing Addendum (Part 7) applies to your use of the Services and is incorporated herein by reference.
2.1 The Services
Talksign provides AI-powered, bidirectional translation between spoken and sign languages and related tools. The Services include, without limitation:
-
Communication Suite. Real-time speech-to-sign and sign-to-speech translation across mobile, desktop, web, and supported smart glasses.
-
Creative Suite. Talksign Canvas, Captions, Avatars, Embed, Live, for creating and publishing sign language content.
-
Marketplace. Licensable multimodal sign language datasets. Users can contribute, annotate, license, and access high-quality sign language datasets while they earn.
-
Education Suite (Talksign Learn). Structured lessons, assessments, progress tracking, and professional certification.
-
Enterprise Suite and API. Programmatic translation, integrations, and organizational deployment.
We may add, modify, or discontinue features at any time. Some features are available only on certain plans or platforms.
2.2 Eligibility and Accounts
-
You must be at least 18 years old, or the age of majority in your jurisdiction, to create an account to use the Services. Minors under the age of 18 may access and use the Services only through an account held, managed, and supervised by a parent, legal guardian, or an authorised educational institution that accepts these Terms on their behalf.
-
Where an educational institution establishes accounts for minors under 18 (such as through Talksign Learn), that institution contractually certifies that it possesses the requisite legal authority to grant institutional consent on behalf of parents or guardians under applicable child data privacy frameworks, including the US Children’s Online Privacy Protection Act (COPPA) and the UK Age Appropriate Design Code (AADC).
-
You are responsible for maintaining the accuracy of your registration information and for keeping your account login credentials completely secure. You are entirely responsible for all activities, data transactions, and actions that occur under your account. You must notify us promptly at support@talksign.co of any unauthorised use of your account or any other known breach of security
2.3 Acceptable Use
Your use of the Services is also governed by our Acceptable Use Policy (Part 5), which is incorporated into these Terms. In summary, you agree not to:
-
use the Services for any unlawful, harmful, fraudulent, or infringing purpose;
-
misrepresent a Talksign automated translation as a certified or legally sufficient human interpretation where a qualified human interpreter is required by law;
-
attempt to reverse engineer, decompile, scrape, or extract our models, datasets, or source code except to the extent this restriction is prohibited by law;
-
upload content you do not have the right to use, including another person's likeness, voice, or biometric data without their consent;
-
interfere with, overload, or circumvent the security, rate limits, or integrity of the Services.
2.4 Translation Accuracy and No Reliance for Critical Use
The Services utilise artificial intelligence and machine learning models, which means outputs will not always be entirely accurate or complete. Automated translation quality is highly variable and depends on multiple external factors, including background audio clarity, individual signing styles, regional sign language variations, ambient lighting, physical positioning, and situational context.
You explicitly acknowledge and agree that:
- As-Is Communication Aid: Talksign outputs are provided strictly as an aid to communication on an “as is” and “as available” basis, without any warranties of absolute accuracy.
- High-Stakes Environments: You must not rely solely or primarily on automated translations in legal, medical, financial, safety critical, or emergency settings where a qualified human interpreter is required, advisable, or otherwise necessary to ensure safety and precision.
- No Certified Substitute: Talksign is an automated tool and does not serve as a legally valid or certified substitute for a professional human sign language interpreter where one is mandated by statutory law, institutional policy, or regulatory framework.
- Mandatory Interface Acknowledgements: To ensure user safety and translation integrity in critical environments, the platform may deploy mandatory, in-app “I Agree” warning prompts and pop-up notifications when high-stakes modes are activated. You must review and formally acknowledge these prompts before proceeding with the use of the platform in those settings.
2.5 Plans, Credits, and Payment
-
Credits: Paid subscription plans include a monthly credit allowance that refills automatically on your specific billing date. Unused credits roll over only up to the explicit threshold limit stated for your chosen plan tier. Credits hold no independent cash value, are non-transferable, and are not redeemable except directly for the execution of the Services.
-
Top-ups: Additional top-up credit packs are available for purchase by active paid plan subscribers and are consumed dynamically according to our published platform burn rates.
-
Billing and Automatic Renewal: Subscription plans renew automatically at the end of each billing cycle until formally cancelled by you through your account dashboard layout. All subscription fees are charged in advance and are strictly non-refundable, except where explicitly required by mandatory local statutory laws.
-
Plan and Price Changes: We reserve the right to modify our subscription prices or core plan features upon providing reasonable advance notice to you. Any price adjustments will take effect dynamically at the start of your subsequent billing cycle.
-
Statutory Cooling-Off Waiver: Under UK and EU consumer protection frameworks, consumers generally possess a statutory 14-day cooling-off period to cancel digital subscriptions and distance contracts. However, by purchasing a Premium or Pro subscription and explicitly requesting immediate operational access to Talksign’s digital service, you acknowledge and agree that you are expressly waiving your statutory right of cancellation and refund under this cooling-off framework once digital performance has commenced.
-
Taxes: All listed platform prices are exclusive of value-added tax (VAT), local sales taxes, or alternative governmental duties and levies unless explicitly indicated otherwise. Applicable regional taxes will be calculated dynamically and displayed clearly at checkout based on your designated billing jurisdiction.
2.6 API and Enterprise Terms
-
API access is subject to the rate limits, credit costs, and plan terms published at docs.talksign.co and any applicable order form.
-
You must keep API keys confidential and are responsible for usage under your keys. We may suspend keys for abuse, security risk, or non-payment.
-
Enterprise customers are governed by a separate signed agreement, order form, and where applicable a Data Processing Agreement((Part 7) which prevail over these Terms to the extent of any conflict.
-
Service levels (including the published uptime SLAs) apply only as stated in the relevant plan or Enterprise agreement.
2.7 User Content and Marketplace
“User Content” means content you upload, create, generate, or publish through the Services, including avatars, captions, and recordings.
-
You retain ownership of your User Content. You grant Talksign a worldwide, non-exclusive, royalty-free licence to host, process, display, and transmit your User Content solely to operate and provide the Services to you.
-
No Model Training: Talksign respects your privacy and creative ownership. We will never use your private conversations, live translation data, or general User Content (such as avatars created in the Creative Suite) to train, retrain, or improve our foundational artificial intelligence models.
-
Exception for Marketplace Contributions: The sole exception to this rule is content specifically submitted and paid for under the Talksign Marketplace Contributor Agreement. Because Talksign outright acquires ownership of this vetted Marketplace data for the explicit purpose of building better translation models, that specific Contributed Content will be used for AI training and development.
-
You are responsible for ensuring you have all rights and consents necessary for your User Content, including any third-party likeness, voice, or biometric data.
2.8 Intellectual Property
Talksign Ownership
The Services, including our models, software, datasets, avatars provided by us, trademarks, and all related intellectual property, are owned by Talksign or our licensors and are protected by law, including under accepted patent rights. Except for the limited rights expressly granted to you, no rights are transferred. You may not use the Talksign name or marks without our prior written consent.
Third-Party Copyrights & DMCA Policy
Talksign respects the intellectual property rights of others and expects users of our Services and Marketplace to do the same. In accordance with the Digital Millennium Copyright Act (DMCA), we will respond to notices of alleged copyright infringement. If you believe that your copyrighted work has been copied or uploaded in a way that constitutes copyright infringement, please notify Talksign’s Designated Copyright Agent with the following information in writing:

Effective July 1, 2026 · Last updated 20 June 2026
Privacy Policy
Effective date: July 1,2026 | Last updated: 20 June 2026
This Privacy Policy explains how Talksign Ltd (“Talksign”, “we”, “us”), company number 17060416, registered at 190 Holliday Street, Birmingham B1 1FD, collects, uses, and protects personal data when you use our Services. It should be read together with our Terms of Service (Part 2).
Our core commitment is simple: we collect as little as we can, we keep it for as short a time as we can, and we never treat your conversations as a product. We do not sell your personal data.
3.1 Who Is Responsible for Your Data
Talksign’s responsibility for your personal data depends on how you interact with our Services:
-
Consumer and Self-Serve Users: Talksign Ltd acts as the Data Controller for personal data processed when you use our consumer apps and direct web services.
-
Marketplace Contributors: If you upload data (such as sign language videos, facial cues, or gestures) to the Talksign Marketplace to monetise or train our AI, Talksign acts as the Data Controller for that specific biometric and content data, governing how it is verified, stored, and distributed.
-
Enterprise and Institutional Customers: When you access the Services through an employer, hospital, or educational institution, that organisation is typically the Data Controller. In these instances, Talksign acts strictly as a Data Processor acting on their written instructions under a Data Processing Agreement (DPA).
Data Protection Officer (DPO) We have appointed a Data Protection Officer to oversee compliance with this privacy notice, including our handling of biometric and special category data under the UK GDPR and the Nigeria Data Protection Act (NDPA).
If you have any questions about this notice, how we handle your personal data, or if you wish to exercise your legal rights, please contact our DPO at:
Email: privacy@talksign.co
**Post:**190 Holliday Street, Birmingham B1 1FD
3.2 Information We Collect
Account, Health, and Profile Data
We collect your Name, Email Address, optional Date of Birth, optional Profile Picture, Country, Timezone, Company details, and Single Sign-On (SSO) identifiers (e.g., Google/Apple) to operate your account.
- Special Category Data (Health): You may optionally provide your hearing or disability status (e.g., Deaf, hearing, interpreter). Because this is classified as sensitive health data, we only process this specific field with your explicit, affirmative consent provided during account setup.
Conversation and translation data (Zero Media Retention)
To provide real-time translation, the Services process audio, sign/gesture, video, facial cues, and text. Where the hardware allows, this processing happens on-device. Where cloud processing is required, the data is routed transiently to our servers, currently hosted on Europe West 2 (GCP London).
- Raw Media is Discarded: We operate a strictly “Zero Media Retention” pipeline for live translations. No raw audio, raw video, or identifiable visual media is cached, logged, or stored on our servers after the translation is delivered.
- What is Kept: We retain the resulting text transcripts (for your personal history and analytics) and anonymised skeletal keypoint tracking data.
Third-Party Invite Data
If you invite a team or family member to Talksign, we collect their email address. We use this data solely to send the one time invitation and do not use it for marketing purposes unless they subsequently create an account.
Financial and Shipping Data
Payment data processing is handled entirely on Talksign's behalf by our primary sub-processor, Stripe. We do not store full payment card numbers, only Stripe tokens and invoice history. If you order physical hardware (like Talksign smart glasses), we collect your shipping address to fulfill the order.
Usage and technical data
For API customers, request history and credit consumption are processed with a 30-day retention period used strictly for billing and abuse prevention. For all users, we process device and log data (such as IP addresses, app versions, partial crash diagnostics and coarse city/country geolocation) to secure the platform, and we utilise Google Analytics to evaluate aggregate usage patterns. For Talksign smart glasses, we also log the device serial number and Bluetooth ID.
Learn and certification data
If you use Talksign Learn, we process course progress, assessment results, and certification records. For assessments incorporating automated oversight, the Education platform uses a lightweight pose and landmark detection model that only outputs numerical coordinate points.
Please note: For formal certification exams, we store student video submissions (users signing) persistently for grading, audit, and credential verification purposes.
Content you create
This includes avatars, captions, recordings, and Marketplace listings you choose to create or publish. This data is stored securely for as long as your account remains active. Upon account deletion, all associated avatars, captions, and datasets are permanently removed from our production systems after 30 days. Talksign does not use any user-generated content or custom marketplace datasets to train or improve our underlying AI models.
3.3 How and Why We Use Data
We only process your personal data when we have a valid legal basis to do so under the UK GDPR and applicable data protection laws. The table below outlines each specific purpose for which we use your data, the categories of examples involved, and the corresponding lawful basis:
| Purpose | Examples | Lawful basis (UK/EU GDPR) |
|---|---|---|
| Provision of Services | Real-time translation processing, custom avatar rendering, Talksign Learn educational tracks, and developer API functionality. | Performance of a contract: Necessary to deliver the core services you have requested |
| Billing and Account Management | Processing subscription payments, issuing invoices, and managing plan tiers. All payment processing is managed securely on our behalf via Stripe. | Performance of a contract: Necessary to administer your account and fulfill our billing commitments. |
| Security and Abuse Prevention | Detecting platform misuse, preventing malicious activities, securing API keys, and monitoring rate limits. | Legitimate interests: Our fundamental interest in ensuring the safety, compliance, and operational integrity of our systems. |
| Service Improvement | Reviewing technical diagnostics, app versions, error logs, and aggregate usage analytics via Google Analytics. | Legitimate interests / consent: Our legitimate interest in debugging platform errors, paired with your explicit consent for non-essential analytical cookies. |
| Special Category / Biometric Processing | Processing real-time sign language, physical gestures, facial cues, and voice modulations during bidirectional translations. | Explicit consent: Collected via a mandatory, unticked checkbox at the point of account creation or feature activation. |
| Platform Communications | Dispatching critical service updates, technical alerts, or administrative notifications. | Performance of a Contract/ Legitimate interests Necessary to keep you informed about critical operational changes to the platform. |
| Invitations & Referrals | Sending a one-time email to a colleague or family | Legitimate interests |
3.4 Model Training
We train our models on datasets co-created with Deaf communities, educators, and researchers, designed to be transparent, representative and ethically sourced.
To protect your privacy and maintain strict operational boundaries, Talksign enforces a clear separation between your live platform data and our artificial intelligence development:
No Conversation Training: User conversation content, including real-time audio, sign language gestures, facial cues, or text transcripts, is processed strictly transiently and is never stored, logged, or used to train, retrain, or improve our AI models.
No General Content Training: We do not use your general user generated content (such as private avatars or custom captions created in the Creative Suite) for algorithmic development.
However, if you explicitly choose to participate in the Talksign Marketplace and sell sign language datasets to us under the Marketplace Contributor Agreement, that specific, vetted data is acquired and processed for the express purpose of training and improving our AI models.
3.5 How We Share Data
We do not sell personal data. We share data only with:
-
Service providers (sub-processors): Cloud hosting, payment processing, and analytics vendors who process data on our instructions under contract. Our primary sub-processors include Google Cloud Platform (GCP) for cloud infrastructure, Stripe for payment data processing, and Google Analytics for aggregate site usage. A current sub-processor list is available to Enterprise customers on request.
-
Enterprise customers: Where you use the Services through an organization, relevant data may be accessible to that organization as the data controller.
-
Legal and safety: Where required by law, regulation, or valid legal process, or to protect rights and safety.
-
Business transfers: In connection with a merger, acquisition, or sale of assets, subject to this Policy.
3.6 International Transfers
Our primary cloud computing infrastructure is securely hosted in Europe West 2 (GCP London). Because we operate across the UK, the US, and other regions, and as our product scales globally across multiple regions, your data may be processed outside your home country.
Where we transfer personal data internationally from the UK to third countries (such as to sub-processors in the US), we ensure it remains protected by implementing legally recognised safeguards. These safeguards include executing the UK International Data Transfer Agreement (IDTA) or the UK Addendum to the EU Standard Contractual Clauses, alongside strict technical measures such as encryption in transit and at rest.
3.7 Data Retention
We hold your data only for as long as is necessary to fulfil the purposes outlined in this Policy. Our specific retention schedules are as follows:
-
Conversation Content: Not retained. All real time audio, video, or gesture data is processed either on device or transiently in the cloud and is immediately discarded. Text transcripts and anonymised keypoints are retained for your history.
-
Creative Suite & User Content: Avatars, captions, and datasets you create are stored for as long as your account remains active. Upon requesting account deletion, this data is permanently and irreversibly removed from our systems after 30 days.
-
API Usage Logs: Retained for 30 days for billing and abuse prevention purposes.
-
Account and Billing Records: Retained for the active life of the account and as required by law for tax and accounting record keeping.
-
Learn and Certification Records: Retained as needed to maintain your valid educational credentials, or until you request deletion. Student video submissions for certification are retained securely to maintain credential validity.
3.8 Your Rights
Depending on where you live, you have specific legal rights over your personal data.
- UK and EU Rights: Under the UK GDPR and equivalent frameworks, you have the right to access, rectify, erase, restrict, port, and object to the processing of your personal data, as well as the right to withdraw your consent at any time.
- US State Rights: If you reside in the United States, you may have additional rights under state laws such as the California Consumer Privacy Act (CCPA/CPRA). These include the rights to know, delete, correct, and opt out of the sale or sharing of your personal information. Talksign does not sell personal data.
To exercise any of these rights, please contact our data protection team at privacy@talksign.co. Because we do not retain conversation content, please note that there is no historical record of your translations available for access, export, or deletion.
You also retain the right to lodge a complaint with a supervisory authority. In the United Kingdom, this is the Information Commissioner's Office (ICO).
3.9 Children
The Services are not directed to children under the age of 18(“Minors”) without the direct involvement and verified consent of a parent, guardian, or authorised educational institution. We do not knowingly collect personal data from Minors outside of these explicitly controlled environments.
- Talksign Learn & Institutional Consent: Where our Education Suite (Talksign Learn) is deployed in school or institutional environments involving students under 18, Talksign relies strictly on the school or district to provide “Institutional Consent”. This framework enables the institution to act as an agent on behalf of parents or guardians, ensuring operational compliance with the US Children’s Online Privacy Protection Act (COPPA) and the UK Age Appropriate Design Code (AADC).
- Remediation: If you are a parent or legal guardian and believe that a Minor has improperly provided personal data directly to Talksign without valid oversight, please contact us immediately at privacy@talksign.co. We will promptly take necessary measures to purge the unauthorised data and terminate the associated account structure.
3.10 Security
We protect personal data using robust technical and organisational measures, including encryption in transit (TLS 1.2 or higher) and at rest (industry-standard AES-256), least-privilege access controls, multi-factor authentication for administrative access, and strict system logging. Most importantly, we rely on a privacy by design architecture that prioritises on-device processing and minimal data retention. While no system is perfectly secure, our strict minimal retention design substantially limits the data that could ever be exposed in the event of a breach.
3.11 Cookies
Our use of cookies, software development kits (SDKs), and similar tracking technologies (including Google Analytics for performance measurement) is described in detail in our Cookie Policy.
3.12 Changes to This Policy
We may update this Privacy Policy from time to time to reflect operational, legal, or regulatory changes. If we make material changes to how we process your personal data, we will provide reasonable advance notice through the Services or by email. Continued use of the Services after these changes take effect constitutes your acknowledgement of the updated Policy. The “Last updated” date at the top of this document reflects the most current version
Effective July 1, 2026 · Last updated 16 June 2026
Acceptable Use Policy
Effective date: July 1,2026 | Last updated: 16 June 2026
This Acceptable Use Policy (the “AUP”) sets out the rules for using Talksign’s websites, applications, API, and services. It forms part of, and is incorporated into, our Terms of Service. By using the Services you agree to this AUP. Capitalized terms have the meaning given in the Terms of Service.
5.1 Purpose
Talksign exists to make communication accessible and inclusive. This AUP protects our users, the Deaf and hard-of-hearing communities we serve, our systems, and the integrity of our translations. We may update it as needed to address new risks.
5.2 Prohibited Content and Conduct
You must not use the Services to create, upload, share, or facilitate any of the following:
-
unlawful, fraudulent, defamatory, harassing, hateful, or discriminatory content;
-
content that sexualizes, endangers, or exploits children in any way;
-
threats, incitement to violence, or content that promotes self-harm;
-
another person’s likeness, voice, signing, or biometric data without their informed consent;
-
deceptive or impersonating content, including misrepresenting an automated translation as a certified human interpretation where one is legally required;
-
malware, spam, phishing, or content that infringes intellectual property or privacy rights.
5.3 Synthetic Avatars and Coincidental Likeness
To facilitate the use of our translation models, Talksign provides a library of default, pre-generated avatars (the “Default Avatars”). By using these Default Avatars, you acknowledge and agree to the following:
-
AI-Generated Fictions: The Default Avatars are entirely synthetic and generated by artificial intelligence. They do not depict real, existing individuals.
-
Coincidental Resemblance: Any visual resemblance between a Default Avatar and any actual person, living or deceased, is entirely accidental and purely coincidental.
-
Strict Impersonation Ban: You are strictly prohibited from representing or passing off the Default Avatars as real people. You must not use these avatars to deceive third parties, create fraudulent endorsements, or suggest that a real individual is speaking or signing.
-
No Exclusive Ownership: The Default Avatars remain the property of Talksign. You are granted a limited licence to use them within the platform, but you cannot claim exclusive intellectual property rights or right of publicity over any Default Avatar.
5.4 Respect for the Deaf Community
Because our Services represent and translate sign language, misuse can directly harm Deaf individuals and communities. You must not use the Services to mock, misrepresent, or produce deliberately false sign language content, or to present Talksign output as the verified statement of a real person without their consent.
5.5 Technical and Security Restrictions
-
Do not attempt to reverse engineer, decompile, scrape, or extract our models, datasets, or source code, except where this restriction is prohibited by law.
-
Do not probe, scan, or test the vulnerability of the Services, or breach security or authentication measures, without our prior written permission.
-
Do not exceed or circumvent published rate limits, credit allowances, or quotas, or share API keys to evade limits.
-
Do not use automated means to overload, disrupt, or degrade the Services.
5.6 Critical-Use Restriction
The Services are an aid to communication and are not certified for sole reliance in legal, medical, financial, safety-critical, or emergency settings where a qualified human interpreter is required. You must not deploy the Services as the sole communication method in such settings in a way that contravenes applicable law or this restriction. This mirrors section 2.4.
5.7 API and Developer Responsibilities
-
If you build on the Talksign API, you are responsible for your application’s compliance with this AUP and for your end users’ conduct.
-
You must present accurate information to your end users about Talksign’s role and the limits of automated translation.
-
You must implement reasonable safeguards against abuse in your own application.
5.8 Reporting Abuse
To report content or conduct that violates this AUP, contact abuse@talksign.co. We review reports and may act on them, including removing content or suspending accounts.
5.9 Enforcement
Violations may result in content removal, feature or account suspension, API key revocation, or termination, with notice where reasonably practicable. Serious violations, including those that create legal exposure or risk to safety, may result in immediate action. We may report unlawful activity to the relevant authorities.

Data Processing Addendum
Effective date: July 1,2026 | Last updated: 16 June 2026
This Data Processing Addendum (“DPA”) supplements the Talksign Master Terms of Service or Enterprise Agreement (the “Agreement”) entered into by and between Talksign Ltd. ("Talksign", “Processor”) and the school, enterprise, or entity subscribing to the Services (“Customer”, “Controller”).
1. Definitions
- “Data Protection Laws” means all applicable privacy and data protection laws, including the UK GDPR, EU GDPR, US state privacy laws (e.g., CCPA), FERPA, and COPPA.
- “Personal Data” means any information relating to an identified or identifiable natural person processed by Talksign on behalf of the Customer.

7. Personal Data Breach
If Talksign becomes aware of a confirmed Personal Data Breach affecting the Customer’s data, Talksign will notify the Customer without undue delay (and in any event within 48 hours). Talksign will provide sufficient information to allow the Customer to meet its own regulatory reporting obligations.
8. International Data Transfers
If Talksign transfers Personal Data originating from the UK or the European Economic Area (EEA) to a country not recognised as providing an adequate level of protection, Talksign will ensure such transfers are governed by a valid transfer mechanism, such as the UK International Data Transfer Addendum or the EU Standard Contractual Clauses (SCCs).
9. Audit Rights
Upon the Customer’s written request, Talksign shall make available all information reasonably necessary to demonstrate compliance with this DPA. This audit requirement shall be primarily satisfied by Talksign providing the Customer with a copy of its most recent independent security audit report (e.g., SOC 2 Type II or ISO 27001 certification), subject to strict confidentiality obligations.

Web Accessibility Statement
Effective date: July 1,2026 | Last updated: 22 June 2026
Our Commitment to Inclusion
At Talksign, our core mission is to bridge communication gaps through real-time sign language translation. Because our work touches healthcare, education, and daily communication, we believe that digital inclusion is a fundamental human right, not an optional feature.
We are fully committed to ensuring that our websites, applications, and digital platforms are accessible to everyone, including individuals with visual, auditory, motor, and cognitive disabilities.
We strive to create a digital environment that embodies our guiding principle: built with, not for, the Deaf and disabled communities.
Conformance Status
The Web Content Accessibility Guidelines (WCAG) define requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA.
Talksign is committed to achieving and maintaining conformance with WCAG 2.2 Level AA standards across our primary digital properties, including our web dashboard and Talksign Learn interfaces.
Measures to Support Accessibility
To ensure our platform remains accessible, Talksign takes the following internal measures:
- Accessibility by Design: We integrate accessibility checks directly into our software development lifecycle and procurement practices.
- Community Testing: We actively involve Deaf, hard of hearing, and neurodivergent users in the usability testing of our products.
- Continuous Auditing: We conduct regular internal accessibility reviews and periodic audits using both automated tools and manual screen reader testing.
- Clear Media Alternatives: Because our platform processes visual sign language, we prioritise clear, customisable text transcripts and visual indicators across our user interfaces.
Compatibility with Browsers and Assistive Technology
Talksign’s web platform is designed to be compatible with standard assistive technologies, including:
- Modern screen readers (e.g., NVDA, JAWS, VoiceOver, and TalkBack).
- Standard operating system accessibility features (e.g., high contrast modes, magnification tools).
- Major modern web browsers (Chrome, Firefox, Safari, Edge) on Windows, macOS, iOS, and Android.
Technical Specifications
The accessibility of Talksign relies on the following technologies to work with the particular combination of web browser and any assistive technologies or plugins installed on your computer:
- HTML
- WAI-ARIA
- CSS
- JavaScript
These technologies are relied upon for conformance with the accessibility standards used.
Known Limitations
Despite our best efforts to ensure the accessibility of Talksign, there may be some limitations as we continuously update our platform.
- User Generated Content: While our core interfaces are rigorously tested for accessibility, content uploaded or created by third party users in the Creative Suite or the Talksign Marketplace (such as raw video datasets or custom unedited captions) may not fully meet strict WCAG standards.
Feedback and Reporting Barriers
We welcome your feedback. If you encounter any accessibility barriers on our website, applications, or API documentation, please let us know so we can fix it.
- Email: support@talksign.co (Please include “Accessibility Barrier” in the subject line)
- Response Time: We aim to respond to accessibility feedback within two (2) business days and will work closely with you to propose a suitable workaround or permanent fix.
- Enforcement Procedure: If you are based in the UK and remain dissatisfied with our response to your accessibility complaint, you can contact the Equality Advisory and Support Service (EASS) for further guidance.
Legal Compliance
This statement affirms our ongoing commitment to fulfilling our obligations under the UK Equality Act 2010, the European Accessibility Act (EAA), and the Americans with Disabilities Act (ADA) regarding digital public accommodations.
