What are cookies
Cookies are small text files stored on your device by your browser. They're commonly used to remember preferences, measure site usage, and serve relevant advertising.
How we use cookies
- Essential: Basic cookies or local storage that help the site function correctly.
- Analytics: We use Google Analytics cookies to understand which calculators are useful and how visitors navigate the site. These only load if you accept cookies in the banner — see Google's cookie use for details.
- Advertising: This site is designed to display third-party advertising (such as Google AdSense) to keep every calculator free. Advertising partners may set cookies to serve and measure ads based on your browsing activity across sites.
Your choices
When you first visit this site, a banner asks you to Accept or Reject non-essential cookies. Your choice is remembered on this device so you won't be asked again. To change your mind, clear this site's data in your browser settings and reload the page — the banner will reappear.
You can also block or delete cookies through your browser's own settings, or opt out of personalized advertising via industry tools like the Digital Advertising Alliance. Blocking cookies may affect how ads are shown but will not affect your ability to use the calculators themselves.
Third-party cookies
When advertising is active on this site, our ad partners are responsible for the cookies they set. We encourage you to review their own privacy and cookie policies for details on what they collect.
