How can I help?
I make these apps on my own, so every message reaches me, not a ticket queue.
Tell me which app, your iPhone model and iOS version, and what happened. A screenshot helps a lot.
Which app is it about?
Quick answers
Most questions are about purchases and moving to a new phone. Not here? Just email me.
Sign in with the same Apple ID, open the app, go to its Pro screen and tap Restore Purchases.
Open Settings on your iPhone, tap your name, then Subscriptions. Pick the app and cancel. Apple handles it, so it works even if the app is deleted.
Not if iCloud sync is on in the app (where it offers it). Otherwise your data comes along with an iPhone backup or a device-to-device transfer.
Refunds are handled by Apple. Request one at reportaproblem.apple.com with the Apple ID you used.
The privacy policy covers every app: what stays on your iPhone, the few services each one talks to, and why.
