Privacy Policy

Last updated: 2026

CalcSuite ("we", "us") operates this website of free online calculators. This policy explains what information we do and do not collect.

Calculator inputs stay on your device

All calculations run entirely in your browser using client-side JavaScript. The numbers, dates and values you type into any calculator are never sent to our servers and are never stored by us.

Analytics

We may use privacy-respecting analytics to understand aggregate, anonymized traffic (such as which calculators are most popular). This does not identify you personally.

Advertising and cookies

This site is supported by advertising. We use Google AdSense to display ads. Third-party vendors, including Google, use cookies 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 visit to our sites and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. For more information about how Google uses data, see Google's partner sites policy.

Children

This site is intended for a general audience and is not directed at children under 13.

Changes

We may update this policy from time to time. Continued use of the site after changes constitutes acceptance of the revised policy.
