Your calculator inputs never leave your device. Every formula on this site runs in your browser. We have no server that receives, stores, or sees the numbers you enter.

Waitlist emails. If you join a waitlist, we store the email address you provide and which tool you signed up from, solely to send you launch information. We don't sell, share, or rent it. One email to unsubscribe.

Analytics. We use privacy-respecting, cookieless analytics to count page views and understand which tools get used. No cross-site tracking, no advertising identifiers.
