What is a cookie?
Cookies are small text files sent by us to your computer or mobile device which enable Slack features and functionality. They are unique to your account or your browser. Session-based cookies last only while your browser is open and are automatically deleted when you close your browser. Persistent cookies last until you or your browser delete them or until they expire.
To find out more about cookies, visit this site.
Some cookies are associated with your account and personal information in order to remember that you are logged in and which workspaces you are logged in to. Other cookies are not linked to your account; these cookies are unique and allow us to perform analytics and customisation, among other actions.
Cookies can be used to recognise you when you visit a Site or use our Services, remember your preferences and give you a personalised experience that is consistent with your settings. Cookies also make your interactions faster and more secure. Visit our cookie tables to learn more.

What third-party cookies does Slack use?
You can find a list of the third-party cookies that Slack uses on our Websites along with other relevant information in our cookie tables. While we do our best to keep this table updated, please note that the number and names of cookies, pixels and other technologies may change from time to time. Third-party cookies are limited to our Websites and are not used in our Services.
How are cookies used for advertising purposes?
Cookies and other ad technology such as beacons, pixels and tags help us market more effectively to users that we and our partners believe may be interested in Slack. They also help provide us with aggregated auditing, research and reporting, and to know when content has been shown to you. These cookies are limited to our Websites and are not used in our Services.
What can you do if you don’t want cookies to be set or want them removed, or if you want to opt out of interest-based targeting?
Some people prefer not to allow cookies, which is why most browsers give you the ability to manage cookies to suit you. In some browsers, you can set up rules to manage cookies on a site-by-site basis, giving you more nuanced control over your privacy. What this means is that you can disallow cookies from all sites except those that you trust.
Browser manufacturers provide help pages relating to cookie management in their products. Please see below for more information.
- Google Chrome
- Internet Explorer
- Mozilla Firefox
- Safari (desktop)
- Safari (mobile)
- Android Browser
- Opera Mobile
For other browsers, please consult the documentation provided by your browser manufacturer.
You can opt out of interest-based targeting provided by participating ad servers through the Digital Advertising Alliance (http://optout.aboutads.info/). In addition, on your iPhone, iPad or Android, you can change your device settings to control whether you see online interest-based ads.
If you limit the ability of websites and applications to set cookies, you may worsen your overall user experience and/or lose the ability to access the services because they will no longer be personalised to you. Doing this may also stop you from saving customised settings, such as login information.
Does Slack respond to “do not track” signals?
Our Sites and Services do not collect personal information about your online activities over time and across third-party websites or online services. As a consequence, “do not track” signals transmitted from web browsers do not apply to our Sites or Services and we do not alter any of our data collection and use practices if we receive such a signal.
