Mattermost Cookie Policy

At Mattermost, trust is our No. 1 priority and we always aim to be transparent about our practices. This Cookie Policy provides information about our use of cookies. Any Capitalized terms used in this Cookie Policy but not defined have the meaning set forth in our Privacy Policy.

What are Cookies

We use cookies on our Sites and Service (as defined below). Cookies are small text files that a site or its service provider transfers to your computer or mobile device (if you allow). These cookies are unique to your account, browser, or device and enable the site or service provider to recognize your browser and/or device, and, if you have a registered account, associate it with your registered account. 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.

We use cookies (both session and persistent) and similar technologies (collectively, “Cookies”). We use Cookies on the websites operated by Mattermost, Inc., and our affiliates (collectively, the “Sites”) and in the products and services we provide (collectively, the “Service”). We also use trusted third party cookies.

Information that is Automatically Collected and How Mattermost Uses Cookies

We may use both session and persistent Cookies to convey information to us, such as: identify that you’ve logged in to the Service; your Internet Protocol address; unique device identifiers; your browser settings and specification; and information about how you use the Service (e.g., the pages you view, the links you click, features and functionalities you utilize, how frequently you access the Service, and other actions you take on the Service). Cookies also allow us to track your usage of the Service over time.

We use the following types of Cookies:

  • Operationally Necessary Cookies: These Cookies allow you access to our Service or to make use of certain functionality.
  • Preferences: These cookies allow our Site and Service to remember the choices that you’ve made in the past, like what language you prefer, your timezone, or your username and password so you can automatically log in.
  • Security: These cookies enable and support our security features and help us to detect malicious activity.
  • Statistic and Performance: These Cookies collect information about how you use the Site and Service and help us assess the performance of the Site and Service, such as which pages you visit and which links you click on. This information is aggregated and anonymized and used to improve the Site and Service functionality.
  • Marketing/Targeting/Advertising: These Cookies help us market more effectively to users that we and our partners believe may be interested in Mattermost. They also help provide us with aggregated auditing, research, and reporting, and know when content has been shown to you.

Third Party Data Collection and Advertising

We strive to give you choices about how your personal information is used.  We do not sell, trade, or otherwise transfer the information we collect from you to unaffiliated third parties. We do, however, share the information we collect from you with trusted third parties who assist us in operating our Site, conducting our business, or providing the Service to you, provided that those parties agree to keep your information confidential and secure. 

This includes sharing the following anonymous usage statistics about the Service on the Gfycat feature with Gfycat: which gifs are viewed and shared (without identifying specific users); how many users have used the feature; and the search terms and categories that are selected from the Gfycat picker.
