Privacy Policy

Calculator Collection is a free service that does not require an account or collect personal information from you directly. This page explains the limited third-party tools we use and what they do.

Analytics

We use Google Analytics 4 (GA4) to understand which calculators are useful and how people find the site. GA4 collects aggregated information such as the pages you visit, your approximate location (country/region), device type, and referring site. We do not link this data to any personal identifier.

Advertising

We display ads through Google AdSense to keep the site free. Google may use cookies to serve ads based on your prior visits to this and other sites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Cookies

The only cookies set on this site are those used by Google Analytics and Google AdSense, as described above. We do not set any first-party cookies of our own.

Data sales

We do not sell, rent, or share your data with third parties beyond the analytics and advertising providers listed above.
