Privacy Policy

Last updated: 30 October 2026.

The short version

Your numbers never leave your device. Every calculator on this site runs entirely in your browser; we have no server that receives, stores or processes your data sets, and there are no accounts to sign up for.

What we collect

• Your calculator input: nothing. Values you type or paste are processed locally by your browser and are gone when you close the tab.
• Analytics (once enabled): we use Google Analytics 4 to understand which pages and calculators are useful, in aggregate — pages visited, approximate region, device type, and events such as "a calculation happened on this page". Analytics does not receive the numbers you enter. You can block analytics with any standard tracker blocker without affecting the calculators.
• Email: if you write to us, we keep the message and your address to reply and to track the correction or request.

Cookies

The calculators themselves set no cookies. If analytics is enabled, Google Analytics sets its standard cookies to distinguish visits; that is the only cookie use on this site. There is no advertising, no cross-site tracking by us, and no sale of data — there is no data to sell.

External links

Pages link to our sister site (calculatezscore.com) and occasionally to reference sources. Those sites have their own privacy practices; this policy covers only Mean Calculator.

Changes

If this policy changes, the new version will appear on this page with an updated date. Questions: hello@onlinemeancalculator.com.
