Conversion is 100% local. Privacy you can verify. Our apps do not use third-party analytics, advertising SDKs, tracking SDKs, data brokers, or third-party service connections. We encourage every user to turn on Apple's App Privacy Report to see this for themselves. To enable App Privacy Report on iPhone or iPad, open Settings > Privacy & Security > App Privacy Report > Turn On App Privacy Report. After you use the app for a while, iOS will show the network domains contacted by the app. For our apps, expected network activity should be limited to Apple-operated services needed for normal App Store, iCloud, device, or system functionality. We believe privacy claims should be inspectable, not merely promised.
