Effective date: 1 August 2026
CalcWheel ("the app") is a math puzzle game for iPhone. This policy explains how the app handles information. In short: CalcWheel does not collect, store, or share any personal data.
CalcWheel does not collect any personal information. The app has no user accounts, no sign-in and no registration. We do not ask for your name, email address, location, contacts, photos, or any other personal data.
Your game data — level progress, daily-puzzle history, streaks, hint balance, app settings, and a local record of your purchases — is stored only on your device. It is never transmitted to us and is not accessible to us. Deleting the app removes this data from your device.
CalcWheel offers optional in-app purchases (CalcWheel Pro and hint packs). These are processed entirely by Apple through the App Store using your Apple Account. CalcWheel never sees or receives your payment details — card numbers, billing information and the like. Purchase and "restore purchases" functions are handled by Apple's StoreKit; Apple's handling of that information is governed by Apple's Privacy Policy.
CalcWheel contains no analytics, no third-party tracking and no advertising. The app includes no third-party SDKs that collect data, and it does not track you across other apps or websites.
The app connects to the network only to communicate with Apple's App Store — for example to load in-app-purchase prices, complete or restore a purchase, or open the App Store review page. It does not send your data to us or to any other server.
CalcWheel is suitable for all ages and does not knowingly collect any personal information from anyone, including children.
If this policy changes, the updated version will be posted at this URL with a new effective date.
