The short version

Our calculators run entirely in your browser — the numbers you type are never sent to our servers or stored anywhere. We don't ask for accounts, emails or personal information to use any part of this site.

Analytics

We use self-hosted Matomo Analytics to understand aggregate traffic (pages visited, country, device type). Data stays on our own infrastructure and is not shared with or sold to third parties. IP addresses are anonymized.
