Privacy Policy

Numbers you enter

MAD Calculator processes your numbers locally in your browser. The calculation code does not upload your entries or results to a server, put them in the page URL, or store them in a database.

While you use the calculator

Your input and result are held in the page while you use it. Clear removes the input and displayed result. The site does not provide saved calculations or a calculation history.

Your browser may manage form restoration or session recovery independently. Clearing this page does not delete anything you copied to your clipboard or saved elsewhere.

The site uses locally served styles, scripts, and images rather than embedded third-party fonts or media. You do not need to provide a name, email address, or account to use the calculator.

Cookies and analytics

This website uses Google Analytics to understand how visitors use the site. Google Analytics sets first-party cookies — _ga and _ga_FFKV5WWPEK — that store a randomly generated identifier used to distinguish visitors and sessions. These cookies expire after up to 24 months. Reports generated from this data are retained according to the retention settings of our Analytics property. Your calculator input is never sent to Google. For details, see Google's Privacy Policy (https://policies.google.com/privacy). You can opt out of Google Analytics across all websites with the Google Analytics Opt-out Browser Add-on (https://tools.google.com/dlpage/gaoptout).

Advertising

This website may display advertising served by Google AdSense. Third party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings (https://adssettings.google.com). For information about how Google uses data from sites that use its services, see https://policies.google.com/technologies/partner-sites.

Your consent choices

Where required by law — for example, for visitors in the European Economic Area, the United Kingdom, or Switzerland — non-essential cookies are only set after you give consent. You can change or withdraw your consent at any time.

If you have not been shown a consent choice, no non-essential cookies have been set for your visit.

Website delivery and access information

Visiting a website involves network requests, even when its calculations run locally. The infrastructure delivering this website may process technical information such as an IP address, requested page, browser information, and request time to deliver files, maintain security, or diagnose errors.

This technical access information is distinct from the numbers you enter. The calculation code does not send those numbers with website requests. This policy does not promise that hosting infrastructure keeps no access logs.

External links

The website links to external resources, including NIST’s statistics reference. Following an external link takes you to a service with its own privacy practices. That service receives the network information associated with your visit; calculator inputs are not added to the link.

Changes to this policy

This policy describes the current website. If features or data handling change, the policy will be updated to reflect them. The date above identifies the latest revision.
