• Calculator inputs stay in your browser (local storage and the page URL). We do not send them to a server.
• Analytics: we use Cloudflare Web Analytics, which is cookie-free and does not track you across sites.
• Waitlist: if you join, we store your email, the tier you chose, the time, your country (from Cloudflare) and browser type, in a Cloudflare D1 database. A salted hash of your IP address is kept for up to 24 hours for rate limiting. We use the email only to tell you when that tier launches. Ask us to delete it at any time.
• No ads, no selling data, no third-party trackers.
