Welcome to Math Line 98, developed by Logi-Glyph. This Privacy Policy explains how we handle information when you use our mobile application ("App"). We are committed to protecting your privacy and being transparent about our practices.
Player Name (Optional) When you achieve a top-10 score, the App may prompt you to enter a player name. This name is stored locally on your device only and is never transmitted to our servers or any third party (other than as noted in Section 3 regarding advertising).
Game Data (Local Only) The App stores the following data entirely on your device:
Game state (board layout, current score, turn count)
Game history (equations formed, points earned)
Leaderboard entries (player name, score, game configuration)
App preferences (difficulty, sound settings, theme, language)
This data is stored using Room Database and DataStore on your device and is not transmitted to us.
Advertising (Google AdMob) Math Line 98 displays banner advertisements powered by Google AdMob. AdMob may collect and process data about your device and usage for the purpose of serving personalized or non-personalized ads. This may include:
Device identifiers (e.g., Android Advertising ID)
IP address
Device type, operating system version
App usage and interaction data
This data collection is governed by Google's Privacy Policy, which you can review at: https://policies.google.com/privacy
We do not collect personal information on our own servers. Information stored locally on your device is used solely to:
Save and restore your game progress
Display your game history and leaderboard
Remember your preferences (theme, language, sound, difficulty)
All game data is stored locally on your device using Android's standard storage mechanisms (Room Database and DataStore). We do not operate any servers that receive or store your personal data.
You can delete all locally stored data at any time by clearing the App's data through your device's Settings → Apps → Math Line 98 → Clear Data, or by uninstalling the App.
We do not sell, trade, or share your personal information with third parties, except as follows:
Google AdMob — as described in Section 2.3 above
Legal requirements — if required by law or to protect our legal rights
Math Line 98 is a math puzzle game suitable for general audiences, including children. We do not knowingly collect personal information from children under 13. Since all data is stored locally and we collect no data ourselves, the App is designed to be safe for users of all ages.
However, Google AdMob may collect device-level data for advertising purposes. If you are a parent or guardian and have concerns about advertising directed at your child, please review Google's family and children's advertising policies.
The App requests the following Android permission:
INTERNET — Required solely to load and display advertisements via Google AdMob. The App does not use this permission to transmit your game data or personal information.
Since we do not collect or store your personal data on our servers, most standard data rights (access, correction, deletion) are exercised directly on your device. You may:
Delete all game data by clearing the App's data or uninstalling the App
Opt out of personalized ads through your Android device settings under Settings → Privacy → Ads → Opt out of Ads Personalization
Reset your Advertising ID through your Android device's ad settings
This App uses the following third-party services, each governed by their own privacy policies:
Google AdMob — In-app advertising Privacy Policy: https://policies.google.com/privacy
Google Play Services — Ad infrastructure Privacy Policy: https://policies.google.com/privacy
We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last Updated" date at the top of this document. We encourage you to review this policy periodically. Continued use of the App after changes are posted constitutes your acceptance of the updated policy.
This Privacy Policy applies solely to the Math Line 98 mobile application and does not cover any third-party websites or services linked from within the App.
