Stacks. (the “App”) is operated by Khizer Mahmud. Last updated: July 2026.
This policy describes how we handle information when you play Stacks. on iOS or the web demo.
Stacks. stores most game data on your device. We do not require an account for basic play. Optional analytics and ads may collect limited technical data as described below.
This data stays in your browser or app storage unless you enable a future cloud sync feature.
In-app purchases are processed by Apple. We do not receive your payment card details. Apple may provide purchase confirmation metadata required to deliver gems or coins.
The App may show rewarded ads through Google AdMob. AdMob may collect device identifiers and usage data per Google’s Privacy Policy. You may see an App Tracking Transparency prompt on iOS if personalized ads are enabled.
If enabled, we collect anonymous events (sessions, shop views, runs) to improve the game. We do not intentionally collect email, precise location, or contact lists.
Stacks. is not directed at children under 13. We do not knowingly collect personal information from children.
We may update this policy. The “Last updated” date at the top will change when we do.
