Privacy Policy
AimGeometry ("we", "us") respects your privacy. This document describes what data is collected when you use aimgeometry.com and how it is used.
1. What data we collect
Analytics data. We use Google Analytics 4 to collect aggregated, anonymized usage data: pages visited, time on page, browser and device type, approximate geographic region (country / city), and which lessons or drills are started or completed. We do not collect names, email addresses, payment info, or any identifying personal information.
Local browser storage. Your lesson progress (which drills you have passed, your per-shot statistics) is stored in your browser's localStorage under the key aimgeometry.progress.v1. This data never leaves your device. Clearing your browser data will erase it.
Cookies. Google Analytics sets cookies to distinguish unique visitors and measure session duration. No advertising cookies are set unless and until we enable AdSense (see § 4 below).
2. How we use the data
- To understand which lessons users find most / least useful
- To detect bugs (e.g., shot diagnostic errors)
- To prioritize what to build next based on actual usage
We do not sell or share usage data with third parties for marketing purposes.
3. Third-party services
- Google Analytics 4 — usage analytics. Google's privacy policy.

4. Advertising (future)
AimGeometry plans to display Google AdSense ads once eligibility criteria are met. When ads are enabled, Google may use cookies to serve personalized advertising. You will be able to opt out via Google's Ad Settings. Until that point, no advertising cookies are set.
