Privacy Policy for Mental Math Trainer – PureMath (Mental Maths Games – PureMath)
Last updated: October 11, 2026
Your privacy is important to us. This Privacy Policy explains how Mental Math Trainer – PureMath (“the App” “we,” “us,” or “our”) handles your information.
• Overview
PureMath is designed to respect your privacy. We do not collect your name, email address, or any other information that directly identifies you. We do not use advertising, and we do not track you across other apps or websites.
• Data stored on your device
Your progress, statistics, and settings are stored only on your device. This information is not sent to us or to any third party.
• Anonymous usage analytics (TelemetryDeck)
To understand how the app is used and to improve it, we use TelemetryDeck, a privacy-focused analytics service based in Germany. TelemetryDeck receives anonymous usage signals, which may include:
– An anonymous identifier generated for your app installation, which cannot be used to identify you personally
– Actions taking place in the app (for example, “app launched” or “level completed”)
– A timestamp rounded to the nearest hour
– Basic device and app information (for example, app version, operating system version, device model, language and region settings)
TelemetryDeck does not store IP addresses, does not use cookies, and does not use persistent identifiers that follow you across apps. The data is anonymous and does not allow conclusions to be drawn about you personally. We do not use this data for advertising. More information: https://telemetrydeck.com/privacy
• Subscriptions and purchases
Purchases and billing are processed by Apple through its in-app purchase system (StoreKit) on iPhone and iPad, and by Google through Google Play Billing on Android, under Apple’s and Google’s privacy policies. The app itself verifies your purchases on your device to unlock paid features. We do not receive your payment card details, name, or email address.
To understand subscription performance and improve the app, we use RevenueCat in an analytics-only capacity. RevenueCat does not process your purchases or control access to features. It receives information about your purchases and subscription status from Apple (such as which products were purchased, purchase dates, and subscription state), along with an anonymous app user ID generated for your installation and basic technical information such as your device’s country/region and IP address. We do not use this data to track you or for advertising. More information: https://www.revenuecat.com/privacy
• Other third parties
Apart from TelemetryDeck and RevenueCat as described above, the app does not include advertising SDKs, social media plugins, or other third-party analytics.
• Data retention and your rights
We do not hold personal data that identifies you, so there is generally nothing for us to access, correct, or delete on your behalf. If you have questions about data processed by TelemetryDeck or RevenueCat, or wish to exercise rights under laws such as the GDPR or CCPA, please contact us using the link below and we will help where we can.
• Children’s privacy
PureMath is suitable for a general audience. We do not knowingly collect personal information from children. The anonymous analytics and purchase data described above is not linked to any individual.
• Changes to this policy
We may update this policy from time to time. Changes will be posted on this page with a revised date.
