Privacy Policy

Last updated: October 25, 2026 · KinesisApp

KinesisApp is an app by ShiroApps for Android and iPhone. This policy explains what data the app and the services it uses handle, and the choices you have.

Your data stays on your device

KinesisApp has no account and no server of its own. Your favorites, progress, practice history and settings are stored only on your device. We cannot see them, and they are deleted when you uninstall the app.

Ads (Google AdMob)

The free version of KinesisApp shows ads served by Google AdMob. To show ads, measure them and prevent fraud, Google may collect your device's advertising identifier (the Android advertising ID or, if you allow it, the iOS IDFA), your IP address (which can be used to estimate an approximate location), information about your device and the app, and how you interact with the ads.

In the European Economic Area, the United Kingdom and Switzerland, the app asks for your consent with Google's consent form before showing personalized ads. In US states with privacy laws, you can opt out of the use of your data for personalized ads. On iPhone, the advertising identifier is used only if you allow tracking in Apple's prompt. If you do not consent, or opt out, you may still see ads that are not personalized.

Learn how Google uses this data: How Google uses information from sites or apps that use its services and Google's Privacy Policy.

Purchases (RevenueCat)

KinesisApp offers a few one-time purchases (a theme, removing the ads) through Google Play and the App Store. To check that a purchase is genuine, unlock what you bought and restore it on another phone, the app uses RevenueCat, a purchase management service. RevenueCat receives a random identifier that the app creates for this purpose, the receipt of your purchases from the store (which products you bought and when, as Google Play or Apple report them), when the app last contacted the service, and basic information about the device and the app (type of device, operating system version, app version, language and currency). It does not receive your name, email, payment details or store account: the payment itself is handled by Google Play or Apple under their own policies. The identifier is not linked to you; RevenueCat shows us the purchase records kept under it, and aggregate sales statistics. See RevenueCat's Privacy Policy.

To bring your purchases to another phone with the same store account: Settings › Purchases › Restore purchases.

Crash reports (Firebase Crashlytics)

If the app crashes or hits an error, it may send a crash report to Firebase Crashlytics, a Google service: the stack trace, the state of the app and the device at that moment (model, operating system version, free memory and disk), the time, and a random installation identifier that is not linked to you. We use these reports only to find and fix bugs. Firebase keeps them for 90 days.

You can turn crash reports off at any time in the app: Settings › Send crash reports. See Privacy and Security in Firebase.

Your choices

We do not sell your data, and the app does not ask for your name, email, contacts or precise location.

Children

KinesisApp is not directed to children under 13, and we do not knowingly collect data from them.

Changes to this policy

If this policy changes, we will update this page and its date. Important changes will also be noted in the app's store listing.
