Your privacy
Effective November 10, 2026
At a glance
- No login, no advertising and no trackers. Your data is never sold or rented.
- The extension processes subtitles and any text you pick locally in your browser. Nothing of it reaches us.
- Lesson progress and preferences are stored on your own device.
- If you buy a plan, Stripe handles your card. We never see the full number.
This notice describes the information involved when you use the Sign2TV browser extension, Sign2TV Lessons, Sign2TV Converse and the website sign2tv.com (together, the “Service”). The Service is operated by the Sign2TV team (“we”, “us”, “our”), the data controller, whose details are on the Legal notice page. Because we are established in France, the EU General Data Protection Regulation (GDPR) and French data-protection law apply to all our processing, wherever you live.
1. The browser extension
To sign a video the extension must read its subtitles, and to sign highlighted text it must read that text. In detail:
- Subtitles and highlighted text are converted into signs inside your browser. They are neither transmitted to us or anyone else nor stored.
- Online meetings. In Google Meet, Zoom and Microsoft Teams, the extension reads the live captions the meeting app already displays, and only once you choose to show the meeting in ASL. They are processed locally and never sent or kept. Sign2TV does not access your microphone or record meetings.
- The extension activates on its own only on YouTube, Google Meet, Zoom and Microsoft Teams. Everywhere else it stays idle until you press “Turn subtitles into ASL” or use the right-click menu, and then it can access that single tab only. It reads subtitles and the text you select, nothing else: no passwords, forms, messages or browsing history.
- Kept on your device only (in the browser's extension storage): your chosen signer, the signs you've encountered, your key if you bought a plan, and a copy of the vocabulary file.
- The single network request: roughly every 6 hours the extension downloads the newest vocabulary file (
signs-data.json) from sign2tv.com. It's an ordinary file download and carries nothing about you or what you watch. Our server may log the request briefly, like any web server (see section 4).
The extension's handling of information complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.
2. Sign2TV Lessons
Lessons require no account. Your progress (completed units, days running, points and preferences) lives in your browser's local storage. We have no access to it, and clearing your browser data erases it.
3. Sign2TV Converse
- Pressing the microphone uses your browser's built-in speech recognition. In Google Chrome, your voice is sent to Google for transcription, under Google's privacy policy. Other browsers may use a different provider or process speech on the device. We never receive or keep the audio.
- Typed replies are spoken using your browser's built-in voice.
- Conversations aren't stored. Closing the page removes them.
- The microphone only switches on when you press it, after your browser asks your permission.
4. The website
- Server logs. Our hosting provider records standard request data (IP address, browser type, requested page and time). We use it solely to operate and secure the site, and it is removed on the host's regular schedule.
- Fonts. Typefaces are served from our own server, so no font provider sees your visit.
- No tracking cookies. We use no analytics, ad cookies, pixels or fingerprinting. The only data stored in your browser is the lesson progress and preferences described above.
5. Purchases
Payments are handled by Stripe. You provide your name, email, card details and billing country directly to Stripe. We receive your name, email, the plan, the amount and the date, never your full card number. To make your plan work we store your key, plan and end date alongside your email, and the extension verifies the key with sign2tv.com about once a day. We retain these records for as long as tax and accounting rules require (see section 7). Stripe's own processing is covered by the Stripe Privacy Policy.
6. Emails you send us
When you contact us, for instance to request sponsored Pro, propose a partnership or get support, we receive your address and what you write. Sponsored Pro requests may mention your country and circumstances. We use this only to reply and assess your request, keep it confidential, and delete it within 24 months of our last exchange unless you ask us to continue helping you.
7. Why we use your data (legal bases)
| What | Why | Legal basis (GDPR art. 6) | How long |
|---|---|---|---|
| Name, email, plan, amount, date, key | Deliver and support your plan, check your key | Performance of the contract | The plan's duration, then archived |
| Invoices and payment records | Tax and accounting obligations | Legal obligation | 10 years (French Commercial Code) |
| Emails you send us, sponsored Pro requests | Answer you and assess requests | Legitimate interest / your request | 24 months after our last exchange |
| Server logs | Security and keeping the site running | Legitimate interest | The host's standard period, at most 12 months |
8. Sharing and transfers outside the EU
We never sell, rent or trade personal data. We share it only with providers that keep the Service running, acting on our instructions: our web host, our email provider and Stripe for payments, or where the law obliges us. Some of these providers, such as Stripe, may process data in the United States or other countries outside the EU. Those transfers are covered by the EU-US Data Privacy Framework or the European Commission's standard contractual clauses.
9. Your rights
Wherever you live, you can ask to access, correct or erase your personal data, restrict or object to its use, receive it in a portable format, and give instructions about what happens to it after your death (French law). Email hello@sign2tv.com and we'll respond within one month. You can also complain to the French data-protection authority, the CNIL (cnil.fr), or to the authority in your own country. Residents of California and other US states with privacy laws have the same rights through us; we do not sell or share personal information for targeted advertising. Because most data stays on your device, you can also remove it yourself by uninstalling the extension or clearing site data for sign2tv.com.
10. Young people
Lessons suit learners of all ages and collect no personal information. Paid plans are intended for adults; a parent or guardian should purchase on behalf of anyone under 18 (in France, consent for data processing is given by a parent under 15). If you believe a child has sent us personal data, tell us and we'll delete it.
11. Security
The website is served over HTTPS. Since the extension does its processing on your own device, we hold very little personal data to begin with.
12. Updates
When this notice changes, the date at the top changes too. Significant updates will be flagged on the home page before they apply.
