A cookie is a small text file that a site stores on your computer or mobile device when you visit the site. Browsers support cookies and similar technologies (such as local storage and pixels) so that a site like Reddit can remember information about your visit and can use the information to improve your experience and to create aggregated anonymized statistics about usage of the site. In this Notice, we use the term “cookie” to refer both to cookies and similar technologies.
Cookies may be set by the site you are visiting (called “first-party cookies”) or by a third party, such as those who provide analytics or advertising services or interactive content on the site (“third-party cookies”). In addition to using cookies on our sites, we may also serve our cookies (specifically, our advertising pixel) on third-party sites operated by Reddit advertisers who use our advertising technology.
Our first-party cookies include cookies that are strictly necessary, functional cookies, cookies related to analytics/performance and advertising-related cookies.
Strictly Necessary: These cookies are necessary for our services to function properly and securely and cannot be switched off in our systems. You can set your browser to block or alert you about these cookies, but then some parts of the site will not work. These include:
Functional: These cookies enable Reddit to provide enhanced functionality and personalization. If you do not allow these cookies then some or all of these features may not function properly.
Analytics and Performance: These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. They help us to know which pages are the most and least popular and see how visitors move around the site.
Advertising: We use these cookies to deliver advertisements, to make them more relevant and meaningful to users, and to track the efficiency of our advertising campaigns, both on our services and on other sites or mobile apps. Our third-party advertising partners may use these cookies to build a profile of your interests and deliver relevant advertising on other sites.
Third-Party Cookies: Reddit’s services also include cookies from third parties that we partner with directly or indirectly. Many of these third parties are companies that work with us or with advertisers who advertise on Reddit in order to help target ads or measure the results of an advertising campaign.
Third-Party Sites: Third parties who advertise on Reddit may use our advertising technology, including our advertising pixel, on their sites. We may serve advertising cookies when you visit their sites so that we can measure the effectiveness of ads on Reddit and to show you more relevant advertising on Reddit. The placement of these cookies is controlled by the third-party sites.
There are a number of ways you can control how information is collected from cookies on Reddit and how that information is used.
The major online advertising industry groups offer tools to limit how cookies are used for advertising purposes by participating third parties. More information is available on these sites from the Network Advertising Initiative, the Digital Advertising Alliance, and for users in the EU, the European Interactive Digital Advertising Alliance. Also, Google provides web users with the Google Analytics Opt-out Browser Add-on to prevent the collection of data via Google Analytics.
