Privacy Policy

Last updated: 1 November 2026. This policy explains what happens to your information when you use CalcCrib. In short: the calculators run in your browser, we run no accounts and collect no personal information ourselves, and the site is supported by third-party advertising, which is described honestly below.

Calculator inputs

All calculators on this site run entirely in your browser. The numbers you type are not transmitted to us, not stored, and not logged. Closing the page discards them.

Information we collect

The site itself collects no personal information, offers no accounts or sign-ups, and sets no cookies of its own. Our hosting and delivery provider (Cloudflare) processes standard technical data — such as IP address, browser type and request time — in server logs for security and delivery purposes, as described in Cloudflare's privacy policy.

Cookies

We set no first-party cookies. Our advertising partner (below) and its partners may use cookies, web beacons, local storage and similar technologies to serve ads, limit how often you see the same ad, measure ad performance and, where permitted, personalise advertising. You can block or delete cookies in your browser settings at any time; the calculators will continue to work, because they do not depend on cookies.

Third-party advertising

This site is supported by third-party advertising served by the Adsterra ad network. When an ad loads, Adsterra and its advertising partners may collect and use technical information about your device and browsing on this and other sites (for example IP address, browser and device identifiers, and pages visited) to serve and measure ads. That data processing is governed by Adsterra's privacy policy, not by this one.

You can opt out of interest-based advertising from many networks, including via aboutads.info/choices (US) and youronlinechoices.com (EU/UK). Opting out does not remove ads; it makes them less personalised.

Your choices

Beyond cookie controls, you can use your browser's private/incognito mode or tracking protection to limit third-party tracking. Because we hold no personal data about you, there is no account data for us to export or delete; for data held by Adsterra, use the rights described in their policy linked above.

Children

This site is a general-audience tool site and is not directed at children under 13.
