Email [email protected] and I will get back to you. Please say which device and which OS version you are on — it narrows most problems down immediately.
On your device. In the current version, your transactions, the merchants and payees on them, your categories, notes and account names stay there and are never sent to Finyea. Wallet addresses and aggregate totals do leave the device in specific cases — reading a balance from a public blockchain, and answering an assistant question. See the privacy policy for the full detail on what leaves it, and for what happens if that ever changes.
Not yet. Your data lives in the app, so deleting the app deletes it. Treat an uninstall as permanent.
Subscriptions are managed by the app store you bought through, not by Finyea. On an Apple device, open the system Settings app, tap your name, then Subscriptions, and choose Finyea. You can reach the same screen from inside Finyea while your subscription is active: Settings → Finyea Plus → Manage in App Store.
Open Settings inside Finyea and tap Restore Purchases. If it still does not appear, check that the store account signed in on the device is the one that made the purchase, then email me.
Confirm the address is on the chain you selected when you added it. If it is, send me the chain and roughly when the missing transactions happened.
Deleting the app removes everything held on your device. For the one small record kept on the server, see the privacy policy, which explains what it contains and what deleting it involves.
