Your data stays on your device

All calculators and tools on OmniCalc run entirely in your browser. The numbers, text, and dates you enter are processed locally and are never sent to, stored on, or logged by our servers. We do not require or offer user accounts and we do not collect personal information directly.

Advertising and cookies

This site may display advertisements served by third party advertising partners such as Google AdSense. These partners may use cookies or similar technologies 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 based on your visits to this site and other sites on the internet.

You may opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info. Depending on your region, you may be shown a consent prompt before any advertising cookies are set.

Analytics

If analytics are enabled, they are used only in aggregate to understand which tools are useful. No analytics data is ever combined with the values you enter into tools, which never leave your device.
