Mentalator — Privacy Policy
Last updated: September 22, 2026
This Privacy Policy explains how the Mentalator mobile app ("Mentalator", "the app") handles information. The app is published by KAIZEN Games ("we", "us"). You can contact us at any time at contactus@kaizen-games.com.
Summary
- Mentalator does not require an account and does not ask for your name, email, phone number or location.
- We do not operate a server that stores your personal information.
- Your settings, training plans and practice statistics stay on your device.
- Third-party services used by the app (advertising, purchases and your device's speech recognition) may process some data, as described below.
Information stored on your device
The app saves the following data locally, on your device only: your settings (difficulty, operations, digits, voice and language), the training plans you create, and your practice statistics (for example response times and accuracy by operation and by mode). This information is not sent to us. It is removed when you uninstall the app.
Microphone and speech recognition
If you use voice answers, the app asks for permission to use the microphone (and, on iOS, speech recognition). Your spoken answer is turned into text by the speech recognition service that comes with your device's operating system (Google on Android, Apple on iOS). Depending on your device and language, the operating system may send the audio to its provider for processing, under that provider's own privacy policy. Mentalator does not record, store or send audio to us. You can use the app without granting the permission, or turn voice recognition off in Settings and answer by tapping.
Questions are read aloud using your device's built-in text-to-speech.
Notifications
If you set a schedule in a training plan, the app can show reminder notifications. These are local notifications created by the app on your device; no information is sent to us to deliver them.
Advertising
Mentalator shows ads using Google AdMob. Ad providers may collect and use information such as your device's advertising identifier, IP address and general device information to deliver and measure ads, and may use it to show personalized ads, in accordance with their own policies. You can manage ad personalization and reset or limit your advertising identifier in your device settings. Learn more in Google's advertising policies. Ads are removed if you buy "Remove Ads".
If you are in the European Economic Area, the United Kingdom or Switzerland, the app asks for your consent before showing ads, using Google's User Messaging Platform. You can accept or decline, and you can change your choice at any time from Settings → Privacy options in the app. If you decline, you may still see ads, but they will not be personalized.
In-app purchases
The app offers a one-time purchase ("Remove Ads"). Payments are handled entirely by Google Play or the Apple App Store, and we never receive your payment details. To check whether a purchase is active, the app uses RevenueCat, which receives an anonymous app user identifier, information about your purchase (such as the product and its status) and basic device and app information.
Information we do not collect
Mentalator does not collect your name, email address, phone number, precise or approximate location, contacts, photos or files, and it does not require you to create an account.
Children
Mentalator does not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will help resolve it.
Data retention and deletion
Data stored by the app on your device is deleted when you uninstall the app. Purchase records are kept by Google Play, the Apple App Store and RevenueCat under their own policies. If you have any request about your data, write to us at contactus@kaizen-games.com.
Third-party services
- Google AdMob and Google Play Services (advertising, purchases on Android, speech recognition on Android)
- Apple App Store and Apple speech recognition (purchases and speech recognition on iOS)
- RevenueCat (purchase verification)
We encourage you to review the privacy policies of these services.
