Privacy Policy

Last updated: June 2026.

The short version

SepticCompass does not ask for, collect, or store your personal information. Every calculator runs entirely in your browser — the numbers you enter are never sent to us or to any server.

Information we do not collect

We have no accounts, no sign-ups, no contact forms, and no lead capture. We do not sell or share personal data, because we do not collect any.

Analytics

We may use privacy-respecting analytics to understand which pages are useful (for example, aggregate page views and referring search terms). This data is anonymized and is not used to identify you.

Advertising & cookies

This site is supported by display advertising. When advertising is enabled, third-party vendors — including Google — may use cookies or similar technologies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits. You can opt out of personalized advertising via Google Ads Settings, and learn more at Google's advertising policies. Visitors in the EEA, UK, and other regions will be shown a consent banner and can manage their choices there.

Children

This site is not directed at children under 13 and does not knowingly collect data from them.
