The short version

Tangent shows your ChatGPT conversations as a map. To do that, your conversations never need to leave your browser, so they don't. We don't store your chats, we can't read your chats, and there is no analytics or tracking in the extension.

What we actually store

Three small lists of bookmarks: technical IDs marking which branches you created, archived, or merged. They contain no text from your conversations, just reference codes. If you're signed in, these sync to our server (so your map looks the same on your laptop and your desktop). That's it. That's the whole database.

One more thing crosses the wire: to draw the map, the extension sends the shape of your conversation tree (numbered dots and their connections, no text, no names, not even ChatGPT's reference codes) to our server, which computes the drawing positions and sends them straight back. Nothing about it is stored.

What our partners store

We deliberately don't run our own user database. Instead:

• Clerk (our sign-in provider) holds your account: your email address and, if you sign in with Google, your name and profile picture.
• Creem (our merchant of record) handles payment. Your card number goes to them, never to us. We couldn't see it if we wanted to.

What we never do

• We never store, read, or transmit the text of your conversations.
• We never sell or share data with anyone beyond the two partners above.
• There is no tracking, no analytics, no telemetry in the extension.

Your rights (GDPR)

• Delete: delete your account and every trace of your data follows automatically. Your sync data is wiped the moment your account is deleted.
• Access/export: write us and we'll send you everything we hold (it's those three lists, so it will be a short email).
• Contact: support@addtangent.com
