The short version

Calculators run in your browser. Nothing you type into them is sent to us. We set no cookies.

What we collect

• Calculators and embeds: nothing. The math runs on your device.
• Hosted MCP server: your AI app sends the calculation inputs to our server to get a result. We do not store or log those inputs. Our hosting provider keeps standard short-lived request logs (such as IP address and time) for security and rate limiting.
• Analytics: if enabled, cookieless and aggregate only (page views, no personal profiles).
• Email: if you email us, we keep your message to reply. If a newsletter launches, it will be opt-in with one-click unsubscribe.

What we don’t do

We don’t sell or share personal information, run advertising trackers, or build profiles.
