Your game. Your device.

Playing without an account

Rank 10 stores your current attempt, results, streak history, and preferences in your browser’s local storage. They are not synced between devices. Clearing website data or using a private browsing session can erase your history.

Optional analytics

If you opt in, we use PostHog to understand game starts, placements, completion, sharing-button use, and return visits. Events include the puzzle identifier, score, duration, device category, and a random browser identifier. We do not record your screen or collect your name or email to play. Clicking Share does not tell us whether you actually posted your result.

Hosting and administration

Our hosting provider processes ordinary technical request information, such as IP addresses and browser details, to deliver and secure the site. Supabase stores the puzzle library and authenticates the administrator. Players do not need a Supabase account.

Sharing

Sharing sends only the spoiler-free result text or image you choose to the app you select. Rank 10 does not post to your contacts or social accounts automatically.

Managing your data

You can withdraw analytics permission above. To remove your local gameplay history, clear this site’s storage through your browser settings. This removes your saved results and streak.
