Privacy

The short version: we know almost nothing about you, and we like it that way.

What we store

• Game state and statistics (your current puzzle, streaks, win distribution) are stored in your browser's localStorage on your device. They are never transmitted to us. Clearing your browser data deletes them.
• No accounts. We have no way to identify you.
• No cookies are set by SortStack itself.

Analytics

If enabled, we use Cloudflare Web Analytics, a privacy-first, cookieless measurement tool that does not fingerprint users or track you across sites.

Advertising

SortStack may display ads served by Google AdSense in the future. If ads are active, Google and its partners may use cookies or similar technologies as described in Google's policy, and you can opt out of personalized advertising at Google Ads Settings. If you don't see ads on this site, none of this applies yet.
