Privacy Policy

The short version

The calculators run entirely in your browser. The numbers and dates you type are processed on your own device and are never sent to this site or anywhere else. We do not ask you to create an account and we do not collect personal information through the tools.

What the calculators do with your input

Nothing leaves the page. When you enter a date, JavaScript running in your browser computes the result and writes it into the page. There is no form submission, no API call and no logging of the values. Closing the tab discards them.

Server logs

Like virtually all websites, the hosting provider records standard request logs when a page is served. These typically include the IP address, the requested URL, the time of the request, and the browser user agent. They are used to keep the site running and to investigate abuse or errors, and they are not used to build a profile of individual visitors.

Cookies

The calculators themselves set no cookies. The site may set strictly necessary cookies related to security and caching. If analytics or advertising are introduced in future, this page will be updated before they go live, and any non-essential cookie will be subject to consent where the law requires it.

Third parties

Web fonts are loaded from Google Fonts, which means your browser makes a request to that service and Google receives your IP address as part of it. No other third-party service receives data from these pages.

Children

This site is a general-purpose utility and is not directed at children. It does not knowingly collect personal information from anyone, including children.

Your rights

Because the tools collect no personal data, there is generally nothing held about you to access, correct or delete. Where server logs contain your IP address, requests about that data can be directed to the site operator.

Changes

If this policy changes in a way that affects what is collected, the change will be described here rather than made quietly.
