What does JamCash store when I link a bank?
JamCash stores only the read-only access link that SimpleFIN issues for your setup token. It is encrypted with AES-256-GCM before it reaches the database. Your bank username and password stay with SimpleFIN Bridge; JamCash never sees them.
What happens to transactions I have already edited?
Your edits win. If a sync brings a new version of a transaction you changed, JamCash keeps yours and puts the incoming version in a review queue on the Connections page, where you review it and mark it resolved.
How often does JamCash sync?
JamCash syncs when you ask it to: choose Sync now on the Overview or Connections page. Each run pulls the last 90 days, so a gap of a few weeks between syncs loses nothing.
How do I unlink a bank?
On Connections, choose Disconnect. JamCash deletes the stored access link and keeps the transactions it already pulled. Reconnecting later needs a fresh setup token from SimpleFIN Bridge.
