Frequently asked questions

Where is my data stored?

All records are stored locally on your device. There is no account and no server. Deleting the app permanently deletes its data, so keep your device backed up via iCloud or computer backup.

How do I restore my Premium purchase?

Open Settings inside the app and tap "Restore Purchases". Make sure you are signed in with the same Apple ID used for the original purchase.

How do I manage or cancel a subscription?

Subscriptions are managed by Apple. Open iOS Settings → your name → Subscriptions.
