Signup security
The signup form uses Cloudflare Turnstile. Cloudflare processes the information needed to perform its security check under its privacy policy. The server validates the result before accepting a signup.
Analytics
We count pageviews, referrer domains and broad device and browser categories, and we measure page loading, responsiveness and layout stability with Cloudflare Web Analytics. It uses no cookies, no local storage, no persistent visitor identifier and no fingerprint.
Our own server counts clicks on the copy buttons (prompt and Markdown) as daily totals per page, with no visitor identifier.
The “visited” ticks and “recently viewed” list are kept in your browser’s local storage only. They are never sent to us, and you can clear them by clearing this site’s data.
Newsletter
If you subscribe, we store your email address, the subscription date, the page you signed up from, the version of this policy you agreed to, and random confirmation and unsubscribe tokens. Your address is only used to confirm the subscription and to send updates about new cheat sheets. Every newsletter includes an unsubscribe link, and unsubscribing deletes your subscription record.
