Privacy Policy

This policy covers what CapstoneCalc does — and deliberately doesn't do — with information when you use the site.

Your grades stay on your device

Numbers you type into any calculator here are processed entirely in your browser by JavaScript running on your device. They are never transmitted to our servers, never stored, and never seen by us or anyone else. There are no accounts and no email capture anywhere on the site.

Cookies and advertising

This site is supported by advertising. Google, as a third-party vendor, uses cookies to serve ads on this site; Google's advertising cookies enable it and its partners to serve ads based on your visit to this site and other sites on the internet. You can opt out of personalised advertising by visiting Google Ads Settings, or opt out of a range of third-party vendors' cookies at aboutads.info.

Analytics

We may use aggregate, non-identifying traffic analytics (page views, referrers, country-level location) to understand which calculators are useful. This data is not linked to individuals.

Your rights

Because we hold no personal data about you, there is nothing for us to export or delete under GDPR, CCPA or similar frameworks — the advertising cookies described above are controlled through the Google opt-out links, not through us. Questions: hello@capstonecalc.app.
