Privacy Policy
MARDLE
Last updated: April 13, 2026
Overview
MARDLE is designed to keep data collection light. Most normal gameplay, progress, tokens, and settings stay on your browser or device.
The app also offers optional shared leaderboards through Google sign-in and Supabase, plus optional rewarded ads through Google AdMob on mobile.
Gameplay And Device Data
MARDLE may store gameplay-related and preference-related information such as score history, Global Daily Challenge state, token balances, timing data, saved runs, theme choice, music choice, and audio settings.
This information is generally stored locally on your browser or device so the game can restore your progress and preferences on that same device.
Leaderboards And Google Sign-In
Shared leaderboard features are optional. If you choose to use them, MARDLE uses Google sign-in through Supabase to authenticate your leaderboard account.
Shared leaderboard records may include a stable user ID, generated Maze alias, selected-day or challenge date, score details, and update timestamps. Public leaderboards use automatic Maze aliases instead of your real name by default.
Rewarded Ads
MARDLE only shows mobile ads when you explicitly choose to watch a rewarded ad to earn a token.
Google AdMob and related privacy tooling may process device and advertising information, including the Android Advertising ID where applicable, to deliver, limit, and measure rewarded ads subject to your region and privacy choices.
You can learn more about Google's privacy practices in the Google Privacy Policy.
Sharing And Service Providers
MARDLE uses Google services for sign-in and rewarded ads, and Supabase for leaderboard authentication and storage.
MARDLE does not intentionally request access to your contacts, photos, microphone, camera, or precise location for normal gameplay.
Your Choices
You can continue playing offline without using shared leaderboards.
If ad privacy choices are required for your region, the mobile app provides an in-app Ad Privacy Choices entry point. You can also sign out of leaderboards at any time from Settings.
Retention And Deletion
Local single-player data remains on your device until you clear app storage, clear browser storage, or uninstall the app.
Shared leaderboard account deletion requests can be started from within the app and from the public account deletion page.
When a leaderboard account deletion request is processed, associated shared leaderboard data should also be removed, except where limited retention is needed for security, legal, or fraud-prevention reasons.
Contact
Privacy and deletion questions can be submitted using the developer contact email shown on the Google Play listing for MARDLE.
Changes
This policy may be updated from time to time. When it changes, the date at the top of this page will be updated as well.
