Privacy Policy

We do not run servers that collect your data, and there is no account, sign-up, or login. Your test sessions (the date, the test type, your speed, accuracy, consistency and endurance scores, the counts of correct, wrong and skipped answers, and timings) and your settings (such as your reminder time and display preferences) are stored locally on your device and are never sent to us. The only data that leaves your device is what the third-party services described below (advertising and in-app purchases) need to work.

Scoring, your history, your streak and the best-score and streak shown on the optional home-screen widget are all calculated and displayed on your device. If you turn on the daily reminder, it is a local notification scheduled on your device; nothing is sent to a server, and your device may ask you to allow notifications first. The practice sheet (PDF) is generated on your device. Tests and your history work offline; ads and purchases need an internet connection.

We do not sell or share your test results with anyone. Your results leave your device only if you choose to send them, for example by tapping Share on a result, sending feedback, or sharing a practice sheet, and picking an app in your system share sheet. The app uses these third-party services, each under its own privacy policy: Google AdMob, its mediation partners Unity Ads, ironSource and Liftoff, and Google's User Messaging Platform (ads and ad consent, see Advertising); Apple's App Store (StoreKit) and, on iOS, RevenueCat to process and verify the optional Pro purchase, and Google Play Billing on Android (see In-App Purchases). The app may occasionally show your device's built-in store review card (Google Play / App Store), which those stores handle.

The app is supported by ads served through Google AdMob and its mediation partners Unity Ads, ironSource (Unity LevelPlay) and Liftoff (Vungle). To serve and measure ads, and to limit fraud, these companies collect information from your device, such as device identifiers including the advertising ID, your IP address (from which an approximate location may be derived), your interactions with the app and its ads, and diagnostic information. Where your region requires consent (the EEA, the UK and Switzerland, and US states with privacy laws), Google's consent form (User Messaging Platform) is shown before ads are requested, and you can change your choice at any time in Settings → Privacy choices. Whether ads are personalized depends on your consent choice, your platform and your device's ad settings. On iOS, after any consent form, the app asks for App Tracking Transparency permission: your advertising identifier is used only if you allow tracking, otherwise ads are not personalized, and you can change this at any time in iOS Settings › Privacy & Security › Tracking. The app itself does not read or store this identifier. Google's use of this data is described at https://policies.google.com/technologies/partner-sites; see also the privacy policies of Google (https://policies.google.com/privacy), Unity Ads and ironSource (https://unity.com/legal/game-player-and-app-user-privacy-policy) and Liftoff (https://liftoff.ai/privacy-policy/). You can reset or limit ad tracking from your device's system settings at any time.

The app offers an optional one-time purchase, Tes Kraepelin Pro, which removes ads. On Android the purchase is made through Google Play Billing. On iOS it is made through the App Store (StoreKit) and verified through RevenueCat, which receives an anonymous app user ID and your purchase records (see https://www.revenuecat.com/privacy). Payment details are handled entirely by Apple or Google; we never see them. The app keeps only a local note on your device that you own Pro, and you can ask the store to restore your purchase if you reinstall.

The security of your data matters to us. App data is stored locally in the app's private storage, which other apps cannot normally access, and relies on your device's own protections such as its screen lock and device encryption. The app does not add a separate encryption layer to this local data. We do not transmit your test sessions or results to any server of ours.

We do not retain any personal information on servers of our own. App data stays on your device until you remove it; you can delete all of it by clearing the app's storage in your device settings or by uninstalling the application. Data collected by Google AdMob and RevenueCat is retained according to their own privacy policies.

Our application is not directed at children and is not intended for use by anyone under the age of 13 ("Children"). We do not knowingly collect personally identifiable information from children under 13. If you become aware that a child has provided us with personal data, please contact us at hello@microappdigital.com so that we can take steps to remove such information.

We may update our Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
