Something broken, confusing, or unfair? Tell us. Include your iPhone model and iOS version if it's a bug, and what you were doing when it happened.
We read everything. Replies usually within a couple of days.
I deleted the app. Is my progress gone? If iCloud was on, no — reinstall and it comes back. Progress is stored in your private iCloud, never on our servers.
I bought something and didn't get it. Settings → Shop → Restore purchases. If that doesn't do it, email us with the receipt.
Can I turn off the reminders? Settings → Reminders → Off. They're never more than two a day anyway.
