Privacy Policy
Last updated: July 17, 2026
Brain Gym ("we", "us") is a free browser game operated by HeyPN at braingym.heypn.com. This policy explains what information is handled when you use the site, and the choices you have. The short version: we don't ask for your name, email, or any account โ you can play completely anonymously.
1. Game progress โ stored on your device only
Your game data (peak stage, streaks, chosen mode, sound preference) is saved in your browser's localStorage, on your own device. It is never uploaded to our servers, and we cannot see it. Clearing your browser data erases it permanently.
2. Analytics (Google Analytics 4)
We use Google Analytics 4 to understand how the game is used โ for example how many people visit, which pages are viewed, approximate location (country/city level), device type, and how visitors found the site. GA4 uses cookies and similar identifiers to distinguish visitors. This data is aggregated and does not personally identify you. Google's own use of this data is described in the Google Privacy Policy. You can opt out of Analytics with the Google Analytics Opt-out Browser Add-on.
3. Advertising (Google AdSense)
We may display advertising through Google AdSense in the future. If enabled, Google and its partners may use advertising cookies to serve ads based on your visits to this and other websites. You can manage ad personalisation at Google Ads Settings, and learn more in Google's advertising technologies policy.
4. Contact form
Our contact page uses Google Forms. Anything you submit there (including any contact details you choose to include) is processed by Google Forms and delivered to us. We use it only to respond to your message.
5. Server logs
Like virtually all websites, our hosting provider automatically records basic technical logs (IP address, browser type, pages requested, timestamps) for security and troubleshooting. These logs are not used to identify individual players.
6. Children
Brain Gym is a general-audience puzzle game. We do not knowingly collect personal information from children โ the game requires no personal information from anyone.
7. Your choices
- Block or delete cookies at any time in your browser settings โ the game itself will keep working.
- Clear localStorage to wipe your saved progress.
- Use the Analytics opt-out linked above.
8. Changes to this policy
If our data practices change (for example, when advertising goes live), we will update this page and the "Last updated" date above.
