General Information
Practical Math Worksheets is a mobile application designed to create math worksheets. The app does not create user accounts and does not ask for names, email addresses, phone numbers, or similar personal information.
Local Operation
The app performs its main functions locally on the device. Worksheets and content created by the user are not sent to any server owned by the developer.
Third-Party Services
The app may use Google AdMob, Firebase Analytics, Firebase Crashlytics, and RevenueCat. These services may process limited technical data for advertising, usage analytics, crash reporting, and subscription management.
Advertising
The app may display ads through Google AdMob. AdMob may process data such as advertising ID, device information, and app usage data to show ads and measure ad performance.
Analytics and Crash Reporting
Firebase Analytics may be used to understand app usage, and Firebase Crashlytics may be used to analyze crashes and errors. This information is used to improve performance and stability.
Subscriptions and Purchases
The app may offer subscription options for premium features. Purchases and subscriptions are managed through Google Play and RevenueCat. The developer does not access or store your credit card or payment details.
Data Sharing
The app does not send data to the developer’s own servers. However, the third-party services listed above may process technical and transaction data according to their own privacy policies.
Promo Period and Hashed Device Identifier
To check whether the 15-day promotional period has started or expired, the app may store a hashed technical identifier derived from ANDROID_ID on Android devices and identifierForVendor on iOS devices in Firebase Firestore. This information is not linked to a name, email address, phone number, or user account. ANDROID_ID and identifierForVendor are not stored in raw form; only the hashed technical identifier is used.
This data is used only to prevent misuse of the promotional offer, calculate the promotional period correctly, and provide app functionality.
Children’s Privacy
The app does not knowingly collect personal information from children.
Changes
This Privacy Policy may be updated from time to time. The current version will be published on this page.
