Where Does Commerzbank Store Accounts and Statements?
Commerzbank keeps accounts on its servers with the phone holding session cache, while photoTAN authorization lives in a separate app.
Last updated
Commerzbank splits its footprint. Balances and statements live server-side behind the banking app login. Transfer approval lives in the separate photoTAN app with its own device registration. Both must move.
That two-app design causes most migration pain. The banking app alone shows data but approves nothing. Re-register photoTAN on the new phone before the old one goes offline.
Where Commerzbank stores this, by platform
/data/data/de.commerzbanking.mobil
Private sandbox for session and cache. Accounts are server-side. photoTAN registration is the move-day task; statements follow login automatically.
/var/mobile/Containers/Data/Application/<guid>/Documents
Sandboxed container with the same server archive. Re-register photoTAN on the new phone. Root and jailbreak checks may block modified devices.
Frequently asked questions
How do I export Commerzbank statements?
Export statements per account from inside the app. Older documents regenerate on request. The photoTAN app authorizes transfers but holds no statements itself.
How do I move Commerzbank to a new phone?
Install both the banking app and the photoTAN app, then re-register the new device. Transfers need photoTAN approval again before they work. Statements sync after login without extra steps.
