Please note that opting out of interest-based advertising and cross-device targeting does not mean you will no longer receive online advertising. It does mean that the company from which you have opted out of receiving interest-based advertising or cross-device targeting will no longer deliver ads tailored to your Web preferences and usage patterns on a particular web browser or device.
If you want to opt out from having PubMatic’s services collect information via cookies about your Internet visits, for purposes of interest-based advertising, please use this opt-out option.

- The opt-out only applies to the browser in the device in which you set it. For example, if you set the opt-out while using the Firefox browser, then the opt-out applies only to the Firefox browser on the device where it was set, not other browsers or devices.
- To opt out from other browsers and devices, you will need to repeat the opt-out process in such browsers and devices.
- If you block the opt-out cookie or your browser is configured to block third-party cookies, then the PubMatic opt-out cookie may not work.
- If you delete your cookies, you will need to opt out again. You may download a browser extension that will help preserve the opt-out preferences you set by visiting www.aboutads.info/PMC.

Many of our media buyer clients and data providers are members of the Network Advertising Initiative (NAI) and/or participate in the Digital Advertising Alliance’s (DAA) Self-Regulatory Program, both of which provide opt-out mechanisms for their respective members or participants. If you go to optout.networkadvertising.org or optout.aboutads.info, you can learn how to exercise choice regarding the collection of information about your online activities over time and across multiple third-party websites, mobile applications, multiple devices, or online services for interest-based advertising purposes.
Some of our publisher clients have their own opt-out mechanisms that are linked from their sites or their online-posted privacy policies. You should review the privacy policies of those companies for these opt-out links if you no longer wish to receive targeted advertising from a particular company, or multiple companies.
Our clients and partners may display interest-based advertising to you in mobile applications, based on your use of mobile applications over time and across non-affiliated apps. To learn more about these practices and how to opt out, please visit http://www.aboutads.info/appchoices, download the DAA’s AppChoices mobile app, and follow the instructions provided in the AppChoices mobile app.
