Privacy

Short version: we don't collect your data.

• All calculations run locally in your browser. What you type is never sent to our server.
• Some tools remember your last inputs using your browser's local storage so they are there next time. That data stays on your device, and you can clear it with the tool's Clear/Reset button or your browser settings.
• We don't use cookies, ad networks or advertising trackers. We use Cloudflare Web Analytics, a cookie-free, privacy-first service, to count anonymous page views (which pages are visited, referrer, country). It does not identify or follow you across sites, and nothing you type into a tool is included.
• Our hosting provider may keep standard, short-lived server logs (such as IP address and pages requested) for security and reliability, as almost every website does.
• Links to Gumroad take you to Gumroad's site, which has its own privacy policy.
