Cookie Policy
Last updated: October 20, 2026. What cookies are, which ones we use, and how you control each one.
What cookies are
Cookies are small files that a website saves in your browser. Similar technologies, such as local storage, serve similar functions. They are used to remember choices, measure how the site is used, and, in some cases, display ads.
Which ones we use
| Type | What it is for | Needs consent? |
|---|---|---|
| Essential | Remembering your choice in the cookie notice (saved in your browser's local storage) and keeping the basic functions of the site working. | No |
| Advertising | Allowing Google AdSense and partners to display ads and, if you authorize it, personalize those ads based on your browsing. | Yes, for personalization |
| Measurement | Aggregated statistics about pages visited and performance, so we can improve the content. | Yes, when they use identifiers |
The calculators do not use cookies to store what you type.
Third-party cookies and advertising
Third-party vendors, including Google, use cookies to serve ads based on a user's previous visits to this and other sites. The use of the DART cookie enables Google and its partners to show you ads based on your browsing. Without your authorization, we only request non-personalized ads.
You can turn off personalization at adssettings.google.com or learn more about how Google uses information from partner sites at policies.google.com/technologies/partner-sites.
How to control them
- Through our notice: use the "Cookie preferences" link in the footer to choose between "Necessary only" and "Accept all" at any time.
- Through your browser: Chrome, Firefox, Safari, and Edge let you block or delete cookies in their privacy settings. Blocking all of them may affect how some sites work.
