Where Does the BBBank App Store Data?
The BBBank app keeps login session and cached mailbox documents in private storage on Android and iOS, with accounts restored after login.
Last updated
Badische Beamtenbank runs one app ID on both platforms. Private storage holds login tokens and the document cache. Balances come from servers on login, so local files hold session state and cached PDFs rather than the account itself. That split decides what survives a reinstall. The session is what keeps you signed in.
iOS containers carry per install GUIDs, so the path changes with every install. Keep credentials ready before device switches. Manual copies never transfer login state, and clearing storage while the app runs signs you out. Export statements as PDF from inside the app before wiping. Folder copies miss the encrypted session stores.

Frequently asked questions
Do BBBank accounts survive reinstall?
No. Accounts and letters sync from BBBank servers after login. Local data holds session and cached PDFs. Reinstall and sign back in, then check the mailbox for letters. Folder copies do not carry login state to the new phone.
How do I back up BBBank statements?
Export statements as PDF before wiping. Manual folder copies miss the encrypted session stores and never transfer login. Re register TAN methods on the new device, so keep the activation details ready before you switch phones.
