Where Does BISON Store Holdings and History?
BISON crypto by Boerse Stuttgart keeps holdings server-side with the phone holding session cache in a private sandbox.
Last updated
BISON holdings live with the Boerse Stuttgart account, not on the phone. The sandbox holds login session and cached market views. This post covers the crypto app, not the unrelated Bison Bank apps with similar names.
Verification owns the migration. Identity checks and 2FA gate the new device. After login, portfolios match the old phone exactly, since both read the same server.
Where BISON stores this, by platform
/data/data/de.bisonapp
Private sandbox for session and price cache. Holdings are account-side under the Boerse Stuttgart app package. Do not confuse with Bison Bank apps.
/var/mobile/Containers/Data/Application/<guid>/Documents
Sandboxed container with the same server archive. Savings plans resume after login. Reinstalls only reset device trust.
Frequently asked questions
How do I export BISON transaction history?
Export the transaction history from the app for tax records. Savings plan executions appear in the same history. Keep yearly exports since cost basis needs the full trail.
How do I move BISON to a new phone?
Install and verify on the new phone. Holdings and savings plans sync from the account. The sandbox held cached prices that rebuild on first open.
