Privacy

Last updated 11 November 2026.

What is recorded when you use ReaderTube

• A random visitor ID kept in your browser's local storage. It is not linked to your name unless you sign in.
• What you do on the site: pages viewed, videos you make notes for, how long notes took to appear, which sections you reached, timestamps and links you clicked, code you copied, exercises you ticked and quiz answers you opened.
• How the service performed: how long each part took, how many AI tokens and web searches it used, and errors.
• A one-way hash of your IP address, used for rate limits and to count distinct visitors. The IP address itself is not stored.
• Your device type (desktop, mobile or tablet) and the site you came from, if any.

We use this to see whether ReaderTube is useful, where it is slow, and what it costs to run. It is not sold, not used for ads, and no advertising or tracking cookies are set.

If you sign in with Google

We receive your name, email address and profile photo from Google. We keep a list of the videos you made notes for and which exercises you ticked, so you can see them on My notes on any device. Only you can read that list. Your usage events are linked to your account while you are signed in.

Who processes the data

• Supabase stores sign-in accounts, your notes list and usage events.
• Netlify hosts the site and runs the server code.
• Anthropic (Claude) receives the video's transcript to write the notes.
• TranscriptAPI.com receives the video's ID to fetch its captions.

How long it is kept

Usage events are deleted after 365 days. Your notes list is kept until you remove videos from it or ask us to delete your account.

Opting out

If your browser sends Global Privacy Control or Do Not Track, ReaderTube records no usage events from it. To delete your account and everything linked to it, write to us through the contact page.
