Backups on Android and the web
A sealed copy of your account, encrypted on your device under a key Kata never receives, brings your data to a new phone or browser.
When backup is on in your phone’s settings, Android saves Kata’s backups to your Google account: logs, chats, memory, photos and settings. Google keeps up to 25 MB per app, so with many photos keep an export too.
Kata keeps one end-to-end encrypted copy of your account. It is encrypted on your device with AES-256-GCM before it leaves, under a key Kata never receives. Photos and health app values are never in it, and it is deleted with your account. Sealed cloud copy on the Backup page shows when it was last updated.
On Android, the key is kept for you in Google Block Store with your Google account, so a new Android phone opens the copy on its own. On the web, keep your recovery key.
Settings, Privacy and data, New device, Show my recovery key: 52 letters and numbers. Copy it or Show as QR. It opens your copy on any device.
- On the old phone: Back up now, then Export my data.
- Set up the new phone from your Google backup, install Kata and sign in.
- If your data isn’t there, choose Restore with a recovery key, or Import your file.
