How do I get Pro back on a new phone?

Install the app with the same Google account you used to buy it, open Settings (or the Pro screen) and tap Restore purchase.

I bought Pro but it is still locked.

Make sure you are online and signed in to Google Play with the account you paid with, then tap Restore purchase. If the payment is still “pending”, Pro unlocks when Google confirms it.

Can I get a refund?

Purchases are handled by Google Play. You can request a refund through Google Play; see Google’s refund help page.

Does the app work offline?

Yes. Everything works without an internet connection. Only buying or restoring Pro needs a connection.
