Advertising

UglyCalc uses Google AdSense to display advertisements on our website. Google AdSense is an advertising service provided by Google LLC. Understanding how advertising works on our site helps you make informed decisions about your privacy.

How Google AdSense Works

Google AdSense uses cookies and similar technologies to serve ads based on your prior visits to our website and other websites on the internet. These technologies help Google and its partners serve ads that may be more relevant to you based on your interests and browsing behavior.

Personalized vs. Non-Personalized Ads

Personalized ads are based on your past browsing behavior, including visits to our site and other websites. Google uses cookies to track this information and display ads that align with your apparent interests.

Non-personalized ads are not based on your past behavior. Instead, they may be based on the content of the page you're viewing or your general geographic location. You can opt out of personalized advertising at any time.

You have control over how ads are personalized to you:

  • Visit Google's Ads Settings to opt out of personalized advertising
