3. Google AdSense & Third-Party Advertising Policy
This website may display advertisements served by Google LLC via Google AdSense. In strict compliance with Google Publisher Policies and industry transparency standards, we disclose the following:
- Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites across the internet.
- Advertising Cookies: Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this site and/or other sites on the Internet.
- Third-party ad networks or servers may also utilize cookies, JavaScript, or Web Beacons to measure the effectiveness of their advertisements and/or personalize the advertising content that you see. We do not have direct access to or control over these cookies used by third-party advertisers.
Compliance Notice: We do not share personally identifiable information (such as your legal name, physical address, or private communications) with Google or any third-party advertising partners. All ad serving is conducted via pseudonymous identifiers and aggregated metrics.
4. Opting Out of Personalized Advertising
You have the absolute right to opt out of personalized (interest-based) advertising at any time. If you wish to disable customized ad targeting, you may do so through the following official mechanisms:
- Google Ads Settings: Visit Google Ads Settings (www.google.com/settings/ads) to manage your Google ad personalization preferences or disable personalized ads entirely.
- Digital Advertising Alliance (DAA): Visit www.aboutads.info or YourAdChoices (optout.aboutads.info) to opt out of participating third-party ad networks.

- Browser Controls: You may configure modern browsers (Chrome, Safari, Edge, Firefox) to send "Do Not Track" signals or reject third-party cookies globally.
Note: Opting out of personalized advertising does not mean you will no longer receive online ads; rather, the ads you see will no longer be tailored to your browsing history or perceived interests.
