Common questions

I forgot my PIN. Can you reset it?

No. Your PIN protects the encryption key for your data and is never sent to us, so we cannot recover or reset it. If you use cloud sync, sign out and sign back in with your email to set a new PIN. Without sync, the only option is to reinstall the app, which erases the data on that device.

How do I manage or cancel my subscription?

Subscriptions are billed through your Apple ID. Open Apple's subscription settings (or Settings → your name → Subscriptions on your iPhone) to change or cancel your plan. Canceling keeps Pro active until the end of the paid period.

I bought Pro on another phone. How do I restore it?

Sign in with the same account, open the upgrade screen, and tap Restore purchase. Make sure your device uses the same Apple ID that made the purchase.

How do I export my data?

Open the menu inside the app and choose Export. This downloads a JSON file with everything in your book.

How do I delete my account?

Open the account screen inside the app and choose Delete account. This permanently removes your account and all synced data from our servers. Data stored only on your device is removed by deleting the app.

Where is my data stored?

On your device, encrypted. If you subscribe to Pro, an encrypted copy syncs to the cloud. We cannot read it. See the Privacy Policy for details.
