How encrypted backup works

Backups let you restore chats on a new device without us being able to read them.

1. 1

   Two keys

   Your access key identifies your credits. Your backup key encrypts your chats and is never sent anywhere.

2. 2

   Encrypted before upload

   Each change is encrypted in your browser with AES-256 and uploaded. We store only scrambled data.

3. 3

   Restored with your code

   Your recovery code carries both keys, so a new device can download the backup and unlock it locally.
