Where Does the HEK App Store Data?
The HEK service app keeps login session and cached mailbox documents in private storage on Android and iOS, with records restored after login.
Last updated
Hanseatische Krankenkasse ships its service app under one Android ID with a matching iOS build. Private storage holds the login session and mailbox cache. Letters and bonus documents sync from servers after login, so local files hold session state and cached PDFs rather than the record itself. That split decides what survives a reinstall.
iOS adds a per install GUID. The bundle string was not verified, so quote the App Store ID to support. Keep login credentials ready before switching devices. Folder copies miss the encrypted session stores and never transfer login. Export sick notes and bonus proofs as PDF from inside the app before wiping.

Frequently asked questions
Do HEK documents survive reinstall?
No. Letters and bonus sync from HEK servers after login. Local data holds session and cached PDFs. Re authenticate on the new phone, then check the mailbox for letters. Private folder copies do not carry the session to the new device.
How do I back up HEK documents?
Export sick notes and bonus proofs as PDF before wiping. Manual copies miss the encrypted session stores and never transfer login. Health records stay with the insurer, so sign back in and check the mailbox after reinstall.
