Change Calculator does not collect, store or share any personal data. There are no ads, no accounts, no analytics and no tracking. Everything the app knows stays on your device.
What the app stores on your device
Your settings: the selected currency, the coins and notes you have hidden, and whether the first-run hints have been shown.
Whether you have bought Change Pro, so the app can honour the purchase without asking the App Store every time.
This data lives only in the app’s own storage on your device. It is never sent anywhere. Deleting the app deletes it.
What the app sends over the network
Nothing to me. The app has no server and no analytics.
The only network activity is the App Store itself: when the app checks your Change Pro purchase or you buy it, your device talks to Apple through StoreKit. That exchange is governed by Apple’s privacy policy, and I receive no personal information from it. Apple shows me only aggregated sales figures.
Third parties
The app contains no third-party SDKs. Versions before 5.0 showed ads through AdMob and used Firebase Analytics; both were removed in 5.0.
Children
The app is not directed at children and collects no data from anyone, of any age.
Changes
If a future version collects anything, this page will say so before that version ships, and the App Store privacy label will be updated with it.
