Privacy

Short version: we don't collect anything.

• No accounts, no ads, no analytics, no cookies, no third-party scripts or fonts. Every file comes from this site.
• Your progress, checks and plan are saved in your browser's local storage on this device. They never leave it unless you export them.
• Export gives you a JSON file you control. Import reads a file on your device; nothing is uploaded.
• To delete everything, use "Clear this browser" on My plan, or clear this site's data in your browser settings.
• A service worker stores the site's files so it works offline. It stores only the site itself.
• Like any website, the site's host (Cloudflare) processes standard request data, such as IP addresses, to deliver the pages and protect against abuse. We do not receive analytics or visitor profiles from it.

If page-level visit counts are ever added, they will be cookieless, will not identify you, and will be announced on this page first.
