Privacy Policy
1. Zero Account Registration & Local Browser Storage
FreeBlindBox.com does not require user registration, email sign-up, or password creation. Your checklist progress (`fbb_tracker_*`) and claw machine statistics are saved strictly inside your own device's browser localStorage.
2. Analytics & Cookies (Google Analytics 4 & AdSense)
We use Google Analytics 4 (`G-70Q0LYH2CJ`) with anonymized IP telemetry to measure aggregate page performance and Core Web Vitals. Third-party ad partners (such as Google AdSense) may use standard cookies to serve non-intrusive contextual advertisements in accordance with GDPR and CCPA regulations.
3. Client-Side Social Card Generation
When you export a 1080×1350 pull certificate or CSV checklist, the file is synthesized 100% locally in your browser memory via HTML5 Canvas 2D and Blob APIs. No images are uploaded to external servers.
