Subscriptions and refunds
How do I cancel a subscription?
On your iPhone: Settings → your name → Subscriptions, pick the app, tap Cancel Subscription. You keep access until the end of the paid period.
Deleting the app does not cancel the subscription.
How do I get a refund?
All payments go through Apple, so refunds are decided by Apple — we don’t see your payment and can’t send money back ourselves.
Go to reportaproblem.apple.com, sign in with your Apple ID, choose Request a refund, pick the reason and the purchase. Apple usually replies by email.
I paid, but Pro / Premium isn’t unlocked
Open the app, go to the purchase screen or settings and tap Restore Purchases. Make sure you’re signed in with the same Apple ID you paid with.
Still locked? Email us the app name and the purchase date from your Apple receipt. Please don’t send card details.
Will I be charged after a free trial?
If an app offers a free trial, it becomes a paid subscription automatically when the trial ends. To avoid the charge, cancel at least 24 hours before the end — the date is shown in Settings → your name → Subscriptions.
I got a new iPhone. Do I pay again?
No. Purchases are tied to your Apple ID. Install the app on the new phone, sign in with the same Apple ID and tap Restore Purchases.
Is River Ruler a subscription?
No. “Unlock forever” is a one-time purchase. There’s nothing to cancel.
How do I delete my data?
Most of your data lives only on your iPhone — deleting the app removes it. To delete analytics data we may hold, email us with the subject “Delete my data”. Details are in the privacy policy.
