Effective Date: March 22, 2026
This Privacy Policy outlines how Engineering&Art ("we", "our", or "us") handles information in relation to our mobile game, YekZamin.
YekZamin does not collect, store, or transmit any personal identifying information. We do not require you to create an account, provide an email address, or share your name to play the game.
All game progress, including your high scores, unlocked ships, and collected "O2" currency, is saved locally on your device using standard local storage mechanisms. If you uninstall the game or clear your device's app data, this progress will be permanently deleted. We do not sync this data to any external servers. Because your data is stored locally, we have no access to it and cannot provide or delete it for you.
To support the development of YekZamin and fulfill our mission of contributing to real-world tree planting, the game utilizes Google AdMob to serve advertisements, specifically rewarded video ads that allow players to revive during gameplay.
Google AdMob may collect and process certain information, including device identifiers (such as the Android Advertising ID or Apple IDFA), IP addresses, and usage data, to provide personalized or non-personalized advertising. For more information on how Google uses this data, please review Google's Privacy Policy and Terms.
Engineering&Art is committed to utilizing and respecting open-source tools. YekZamin, along with its promotional materials and websites, incorporates the following:
YekZamin is designed to be family-friendly and is safe for users of all ages. To ensure compliance with the Children's Online Privacy Protection Act (COPPA) and Google Play Family Policies, our advertising network (Google AdMob) is explicitly configured with the "Tag for Child Directed Treatment" setting. This ensures that advertisements served within the game are appropriate for children and that child-directed data collection restrictions are enforced by AdMob. If you believe your child has inadvertently provided personal information to a third-party ad network via our game, please contact the respective network directly or adjust your device's ad tracking preferences.
If you reside in the European Economic Area (EEA), California, or other regions with applicable data privacy laws, you have specific rights regarding your personal data. Because YekZamin does not collect or store your personal data on our servers, we cannot fulfill direct data access, deletion, or portability requests. However, you maintain full control over your data locally: you can permanently delete all game data by uninstalling the application. To manage or opt-out of personalized advertising and analytics data collected by third-party services like AdMob, please navigate to your device settings (e.g., enabling "Limit Ad Tracking" on iOS or "Opt out of Ads Personalization" on Android).
We may update this Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. The updated policy will be effective immediately upon being posted on this page.
If you have any questions or concerns regarding this Privacy Policy or the data practices of YekZamin, please contact the developer, Elham Firouznia, at:
