Common questions

I found a bug, or something isn't working

Email nicopetrides123@gmail.com with your device model and iOS version, and what you were doing when it happened. A screenshot helps a lot. SigmaQuest is maintained by one developer, so replies usually arrive within a few days.

I have a feature request

Send it to nicopetrides123@gmail.com. Requests genuinely do shape what gets built next.

How do I restore a purchase?

Purchases are tied to your Apple Account. Reinstalling the app or setting up a new device will not lose them — use the Restore Purchases option in the app. If a purchase still doesn't appear, email nicopetrides123@gmail.com.

How do I get a refund?

Refunds are handled by Apple, not by us — we have no ability to issue one. Request one at reportaproblem.apple.com.

Where is my data stored, and how do I delete it?

SigmaQuest stores your progress and settings on your device. Deleting the app removes that data permanently — there is no server copy we can restore it from, so it cannot be recovered afterwards.
