Privacy Policy

Last updated: August 2, 2026

What we collect

Calculator inputs are processed entirely in your browser — they are never sent to our servers, stored, or logged. We do not require accounts and do not collect names, emails, or payment information.

Cookies and local storage

We use local storage only to remember your theme preference. Third-party advertising (see below) may use cookies as described in the vendors' own policies.

Advertising

We use Google AdSense to display advertising. Google may use cookies or device identifiers to show personalized or non-personalized ads as described in Google's advertising policies. You can control ad personalization through Google Ads Settings. Where required, a consent prompt is shown before advertising cookies are set.

Affiliate links

Some outbound links are affiliate links; clicking them may set a cookie from the destination site so that a commission can be attributed. This costs you nothing and does not affect how we present prices.

Analytics

We may use privacy-respecting, aggregate analytics to understand which pages are useful. No cross-site tracking profiles are built by us.
