Privacy & Security

Private Characters are encrypted and only accessible and readable by the owner of the character. They are stored in the database in an encrypted form and only decrypted on demand by the user.

All messages are (kinda) end-to-end encrypted with your AI Model. The Model streams them in plain text to the browser, but since it's inside of an HTTPS connection, they are encrypted. Aside from that, they are only visible in plain text while in the browser, decrypted using a key generated with your password. Since your password is also stored (of course) encrypted in the database, it's basically impossible for your messages to be read by others.

This is what a Message looks like in the Database:

As you can see, the message is not readable in the database and can only be decrypted with your password on the client side.
