Privacy Policy
Summary
This site collects nothing. There is no backend, no analytics, no advertising and no third-party scripts. Everything you type stays on your device.
Data we collect
None. Values entered into a calculator are processed in your browser and never transmitted.
Local storage
Two items may be stored in your browser: your light/dark theme preference, and (if applicable) your cookie choice. Clearing your browser data removes them. Neither is transmitted.
Cookies
This site sets no cookies.
Third parties
No third-party scripts, fonts, trackers or ad networks are loaded. Every asset is served from the same origin as the page.
Hosting
Our host may keep standard server access logs — IP address, timestamp and requested page — as an ordinary part of serving the site. Values you enter into calculators never appear in those logs.
Changes
This policy is generated directly from the site's live configuration, so it reflects what the site actually does. Material changes will be published here.
