What cookies are
Cookies are small text files that a website stores in your browser. They can keep a site working properly, or help the owner understand how the site is used.
Cookies we use
| Cookie | Set by | Purpose | Typical lifetime |
|---|---|---|---|
| _ga | Google Analytics 4 | Distinguishes browsers so visits and page views can be counted in aggregate. | Up to 2 years |
| _ga_ followed by an identifier | Google Analytics 4 | Keeps track of the current visit (session state). | Up to 2 years |
Lifetimes are set by Google and may change. Your browser’s cookie settings show the exact values stored on your device.
Browser storage (not cookies)
The calculators also use your browser’s local storage, which is similar to a cookie but stays on your device and is not sent to our server. It holds a short history of your recent calculations and your light or dark display choice. You can clear it with the History controls or by clearing site data in your browser.
Analytics
We use Google Analytics 4 to see, in aggregate, which pages and calculators are visited, how visitors find the site and what devices they use. We do not use it to identify you, and the numbers you enter into calculators are not sent to analytics. Google acts as a service provider for this measurement; see how Google uses information from sites that use its services.
Advertising and other tracking
The site does not currently show advertising and does not use advertising cookies, social media tracking pixels or session recording tools. If that changes, we will update this page and the Privacy Policy before the change goes live.
Cookie consent banner
The site does not currently show a cookie consent banner. Your choices are described below.
How to control cookies
- Use your browser’s settings to block, limit or delete cookies. Each browser’s help pages explain how.
- Install the Google Analytics opt-out browser add-on to stop Google Analytics from collecting data on any website.
- Browser features such as “Do Not Track” or content blockers may also reduce analytics collection.
Blocking these cookies does not affect how the calculators work.
