- Scope
- Mattermost processes personal data to provide its products and services, for company management purposes, and for its own marketing purposes. We may disclose the personal data we process to vendors and other entities that process personal data on our behalf, as well as to other third parties (such as to satisfy laws and regulations, protect ourselves and others, and respond to legally valid requests). We do not sell or license the personal data we process to third parties for their own use. PRODUCT AND SERVICES - Mattermost provides self-hosted and cloud-based collaboration services, acting as a processor while customers serve as data controllers. Self-Hosted Products. We process limited personal data for the self-hosted products to provide, support, and improve these products. Mattermost collects limited service and usage data like diagnostics information, security alerts, and log file reports associated with device identifiers, as well as responses to surveys, unless the customer opts out of such data collection. If the customer permits, we collect personal data about a customer’s end users to support push notification services. Cloud Products. We process personal data for our cloud products to provide, support, and improve these products. To do so, we process personal data related to how our customers’ end users use these products. For instance, when end users interact with our products, we collect information such as Internet Protocol (IP) address, general location, activities on our platform, and information about the device used. When our customers choose to enable push notification options, we collect other information about end users, such as usernames, names, and message preview snippets. Forums and Communities. We process personal data to provide online forums and communities to participants. For instance, we process names, email addresses, physical addresses, phone numbers, and other information that individuals provide to us when they register, create an account, request information, or contribute to forums or communities. We use this information to provide and support forums and communities, respond to inquiries, and send information about our products and services. For the above products and services, we may also process technical information that we collect through cookies and similar technologies for operational and analytics purposes, such as verifying accounts and activity, to improve the performance of services, and drive engagement with our services. COMPANY MANAGEMENT – We process personal data about visitors to our corporate websites to operate and improve our services and respond to inquiries. Some information website visitors provide directly to us. We also collect technical information about website visitors through cookies and similar technologies. We process personal data about employees, job applicants, contractors, and vendors (including names, government-issued identifiers, contact information, and employment or educational history). We collect this data directly from employees, job applicants, contractors, and vendors and we may also collect data from third parties, such as recruiters, to process job applications, manage employment and vendor relationships, and operate our business. We process personal data about our customers, such as administrative users of our services and individuals who purchase our services on behalf of their employer, including information they provide to us, as well as technical information collected through cookies and similar technologies. MARKETING - We process personal data about customers, customer prospects, and website visitors to market our products and services. We may use the personal data we collect about such individuals to inform them of our offerings, to solicit feedback about current offerings, and to develop and market new offerings.

What GDPR means, and what it does not
"GDPR compliant" is a claim, not a certification. The verifiable facts are a public DPA, SCC usage, an EU representative, data residency options and a Data Privacy Framework listing.
Read the GDPR guide and browse all vendors with evidenceQuestions buyers ask
Is Mattermost GDPR compliant?
There is no GDPR certification in general use. The verifiable facts are a public data processing agreement, standard contractual clauses, an EU representative and a Data Privacy Framework listing. See the legal artefacts and the DPF row on this page, each with its capture date.
How does CertReports verify this?
Every state carries a capture date, a source and a snapshot link. Registry rows come from the official registry data; vendor statements come from the vendor’s own page or trust centre; nothing is inferred. Vendors can dispute any row and corrections ship within two business days.
