LingoTube
Privacy Policy
LingoTube helps you learn languages from videos. This policy explains what we collect, why, and the choices you have. We keep it short and we only collect what the service needs to work.
What we collect
- An account identifier. When you first open LingoTube we create an anonymous account so your words can be saved. No name or email is needed for this.
- Your Google name and email, only if you choose to sign in with Google.
- Your learning data: saved words, expressions and sentences with their context, words you mark as known, flashcard progress, practice days and your language settings.
- Text you ask the AI about: the word, expression or sentence you click, with the neighbouring lines for context. For pronunciation feedback (Pro), the short recording you choose to send.
- Usage counts needed for plan limits, such as how many AI analyses you used today.
- Payment status if you subscribe. Payments are handled by our payment provider (Lemon Squeezy); we never see or store your card details.
How we use it
- To run the service: save your words, sync them across your devices and apply plan limits.
- To produce explanations: the text you ask about is sent to Google's Gemini AI service to create the explanation. Recordings are processed for feedback and not kept by us.
- To make answers faster: explanations of public video text are cached and may be shown to other learners. The cache contains no information about you.
We don't sell your data, we don't show ads, and we don't use your data to build advertising profiles.
The Chrome extension
On YouTube video pages, the extension reads the video's captions to show dual subtitles. It does not record your browsing history. It only sends data to our server when you click a word or line to explain it, save a word, or mark words as known, and when the LingoTube website asks it for a video's captions.
Videos
Videos play through YouTube's official player, which is governed by Google's own privacy policy.
Where data is stored
Account and learning data are stored with our database provider (Supabase). Some settings are kept only in your browser's local storage.
Keeping and deleting your data
We keep your data while your account exists. You can ask us to delete your account and all its data at any time by writing to the contact address on this page (coming soon). Removing the website data from your browser deletes everything stored only on that device.
Children
LingoTube is not intended for children under 13. Learners under the age required in their country should use it with a parent's or guardian's permission.
Changes
If we change this policy, we'll update the date at the top. Important changes will be announced in the app.
