Privacy Policy

The short version: the calculators run in your browser, and the numbers you enter never leave your device.

Last updated: June 2026

The values you enter

Every calculator on ProbabilityKit runs locally in your browser using JavaScript. The numbers and inputs you type are processed on your own device and are never transmitted to us, stored, or shared. There is no account system and nothing to upload.

What we may collect

Like most websites, our hosting provider may record standard, non-identifying technical logs (such as the page requested and a coarse timestamp) for security and reliability. If we use a privacy-respecting analytics tool to understand which pages are popular, it collects aggregate, anonymised usage data only — not the contents of any calculator.

Cookies

The calculators themselves do not require cookies to function. If any cookies are used, they are limited to basic site functionality or aggregate analytics, and never store the values you enter into a tool.

Advertising

If advertising is shown on the site in future, ad providers may use cookies or similar technologies in accordance with their own policies. Any such use will be limited to serving and measuring ads and will not access the inputs of any calculator. This section will be updated with specifics if and when ads are introduced.

Third-party links

Some pages may link to external references. We are not responsible for the privacy practices of other websites.

Your control

Because no personal data about your calculations is collected, there is nothing for us to retrieve or delete on your behalf regarding tool usage. You can clear cookies and site data from your browser at any time.
