Third-party cookies (only with consent)
If advertising is enabled and you accept, Google AdSense and its partners may set cookies to show ads, limit how often you see them, measure performance and, where permitted, personalise them based on your visits to this and other sites. If analytics is enabled and you accept, Google Analytics 4 sets first-party cookies such as _ga to distinguish visitors. If you reject, or make no choice, none of these scripts are loaded.
Control personalised ads at adssettings.google.com. Learn how Google uses data from partner sites at policies.google.com/technologies/partner-sites.
Where ads appear
Ads, when enabled, appear only in clearly labelled "Advertisement" areas separate from the calculators. They are never placed inside or next to calculator inputs or buttons. Advertising does not influence calculator results or content.
Changing your mind
Use "Cookie settings" in the footer (shown when ads or analytics are enabled), or clear site data in your browser. More detail is in the privacy policy.
