Your play. Your privacy.
Browser edition · Updated October 2, 2026.
What this browser edition stores
PuzzleCub stores game boards, notes, tutorial progress, target history, elapsed play time and local completion records in your browser. It uses that data to resume play and avoid repeating Classic targets. There is no player account or cloud game-save service in this edition.
You can remove these records by clearing this site’s storage in your browser settings. This also deletes saved games. Private browsing may discard progress when a session ends.
Hosting and external links
Loading the website sends ordinary web requests to its hosting provider, which may process technical information such as IP addresses and request logs to deliver and secure the service. Mobile-store links and other external links take you to services with their own privacy practices.
Advertising and analytics
Third-party advertising and analytics are not enabled in this launch build. We plan to support free play through advertising. Before activating it, we will update these disclosures and provide the applicable consent and privacy controls. The browser edition does not use the mobile app’s billing or AdMob SDKs.
