Analytics

We use Vercel Web Analytics, which collects aggregated, privacy-friendly usage data (such as page views) and does not use cookies to track you across sites or collect personally identifiable information.

Advertising

We display ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. For more options, visit aboutads.info. Visitors in the EEA/UK are shown a consent prompt and can manage their choices there.

If you are a California resident, you may have rights under the CCPA/CPRA regarding personal information. Because we do not collect or sell personal information directly, most requests relate to advertising cookies, which you can control via the links above.
