Privacy Policy
Last updated: October 16, 2026
Short version
Your numbers never leave your device. This site has no account system and no backend: everything you type is processed in your browser and stored only in your browser’s local storage.
What we store
Your calculator inputs and any rates you explicitly save are kept in local storage on your device. Clearing your browser data removes them permanently. Nothing is transmitted to us.
Analytics
We may use Plausible, a cookieless analytics service, to count anonymous page views. It does not use cookies or collect personal data.
Third-party links
This site links to other websites we make. We are not responsible for their privacy practices; each linked site has its own policy.
Contact
This site has no accounts, no forms and no server-side storage, so there is normally nothing to contact us about. If a legal notice is required, it will be posted on this page.
