Mattermost Privacy Policy

Effective Date: December 30, 2024

This Mattermost, Inc. (“Mattermost” or “we” or “us” or “our”) privacy policy (the “Privacy Policy”) is designed to help you understand what information we collect and how we use or share that information.

For self-hosted (on-premises) products, please see the first section of this Privacy Policy. For all other Mattermost products, services, and interactions, please see the remainder of the policy starting with the section entitled “Scope of this Privacy Policy.”

Self-Hosted (On-Premises) Products

This is the only section of the Privacy Policy that applies to end users of our self-hosted (on-premises) products. With self-hosted products, the Customer (defined below) that purchases the Mattermost product also controls the processing of end user data. Mattermost collects limited information related to end users, such as service and usage data like error and diagnostics information, security alerts, log file reports, and other data associated with device identifiers, unless the Customer opts out of this information collection. We refer to this information as “telemetry data,” and it does not include any message contents or end user personal identifiers (but may include device identifiers or Internet Protocol (IP) address). Please see telemetry data for more information.

We use telemetry data to protect and improve the self-hosted products, such as to maintain security and prevent abuse.
To the extent that our processing of telemetry data from self-hosted products is subject to the GDPR, the legal bases for such processing include GDPR Art. 6(1)(b) (performance of a contract) and GDPR Art. 6(1)(f) (legitimate interests).

We may share telemetry data collected through our self-hosted products in limited ways to support the product and comply with law, as follows:

With service providers, subcontractors, partners, vendors, consultants, and others that help us provide the self-hosted products, and are not permitted to use the information collected on our behalf except to help us conduct and improve our business;
To respond or comply with, in our sole discretion, a court order, subpoena, law enforcement, other government request, or other legal process (with or without notice to you, in our discretion) under applicable law;
With buyers, successors, or others in connection with a potential or actual merger, divestiture, restructuring, reorganization, dissolution, or other sale or transfer of some or all of our business or assets;
To: (i) satisfy any applicable law or regulation, (ii) investigate and defend ourselves against any third party claims or allegations, or (iii) protect against harm to the rights, property or safety of us or third parties (including financial loss, or in connection with preventing fraud or illegal activity, and/or to enforce our other agreements with you); and
With our Customer’s consent or at the Customer’s direction.

For Customers who participate in telemetry data collection, we also may collect information through end user surveys. Survey responses may include personal information if survey respondents choose to provide it. In addition, if a Customer chooses to enable push notification services for a self-hosted product, then we will additionally collect personal information about end users to support notifications. When we collect survey responses or information related to push notifications, we use and disclose such information in the same ways as described in this Privacy Policy for end users of our other Services.

If you would like to learn more about our self-hosted products practices, you can contact us at [email protected]. If you are a Customer purchasing a self-hosted product, you can see the sections relating to Customers below to learn how we process your personal information collected through our business interactions.

Scope of this Privacy Policy

The remainder of this Privacy Policy applies to:

Visitors to Mattermost.com, Mattermost forum, Mattermost documentation, Mattermost Community, code repositories, and other Mattermost websites (collectively, the “Sites”)
Mattermost Customers
End users of Mattermost’s cloud products and services (collectively, the “Services”)
Mattermost Community or forum participants, including members and contributors

Our practices for each of these groups are described below. Please read this Privacy Policy carefully. By accessing or using any part of the Services or the Sites, you acknowledge that you have been informed of our practices with regard to your personal information and other data.

Customer Control of Services Data

In order to provide the Services, Mattermost is utilized by an organization (either an employer or another entity or person) (each, a “Customer”) under a contract that governs the delivery, access, and use of the Services. When you are an end user of our Services, the Customer has authorized you to access the Services. The Customer owns and controls the messages, files, or other content submitted to the Services, including your personal information (the “Customer Data”) and your account with the Services and any associated Customer Data that you provide. In these cases, Mattermost acts as a data processor (or service provider) within the meaning of applicable privacy laws, and the processing of Customer Data is governed by any data processing agreement between Mattermost and the Customer in addition to this Privacy Policy. The Customer controls the processing of Customer Data through the Services. Please contact the Customer if you have any questions related to such Customer’s specific settings and privacy practices in relation to the Services.

Information Shared with Third Parties and For What Purposes

We do not sell, trade, or otherwise transfer the information described above to unaffiliated third parties for monetary consideration.

This sharing may include:

With service providers/processors, subcontractors, partners, vendors, consultants, and others that help us with any of the purposes in this Privacy Policy, including by providing tools that integrate with our Sites and Services or by performing services on our behalf such as processing payments, sending email, providing back-office services, or measuring site traffic. Entities designated as our service providers/processors are not permitted to use the information collected on our behalf except to help us conduct and improve our business.
With providers of machine learning and artificial intelligence tools. With respect to information collected through our Services, we make such information available to such providers if they integrate with our Services and only to the extent permitted by our Customers;
With our affiliates, parent companies, subsidiaries, and other related companies, all for the purposes in this Privacy Policy;
To respond or comply with, in our sole discretion, a court order, subpoena, law enforcement, other government request, or other legal process (with or without notice to you, in our discretion) under applicable law;

We also may share information that is not collected through our Services with third parties for marketing and advertising purposes. For both our Sites and Services, we may share information that has been de-identified or aggregated without limitation.

How We Protect Information

We implement a variety of security measures aimed at maintaining the safety of the personal information we collect from loss, misuse, and unauthorized access or disclosure. These steps take into account the sensitivity of the information we collect, process, and store, as well as the current state of technology. Given the nature of communications and information processing technology, we cannot guarantee that information we collect will be absolutely safe.

Cookies and Similar Technologies

As noted above, we use cookies and similar technologies on our Sites and Services. Please read our Cookies Policy for more details.

Digital Advertising and Analytics

Our Services do not collect, use, or share information for advertising. However, in connection with our Sites, we may partner with ad networks and other ad serving providers (“Advertising Providers”) that serve ads on behalf of us and others on non-affiliated platforms. Some of those ads may be personalized, meaning that they are intended to be relevant to you based on information Advertising Providers collect about your use of the Sites and other sites or apps over time, including information about relationships among different browsers and devices. This type of advertising is known as interest-based advertising.

To opt out of these practices or learn more about this type of advertising, you may visit the Digital Advertising Alliance Webchoices tool at www.aboutads.info/choices. You can also opt out of Google ad tracking by following the instructions on this page: https://adssettings.google.com/.

Electing to opt out from interest-based advertising will not stop advertising from appearing in your browser or applications. It may make the ads you see less relevant to your interests. If you use a different browser or device, you may need to renew your opt-out choice.

We may also work with third parties that collect data about your use of the Sites and other sites or apps over time for non-advertising purposes. We use Google Analytics and other third-party services to improve the performance of the Sites and for analytics and marketing purposes. For more information about how Google Analytics collects and uses data when you use the Sites, visit www.google.com/policies/privacy/partners, and to opt out of Google Analytics, visit tools.google.com/dlpage/gaoptout.

Our Legal Bases for Processing in the EU

If the GDPR is applicable as per Art. 3 of the GDPR, then references to “personal information” in this Privacy Policy are equivalent to “personal data” governed by the GDPR.

As described above, we rely on various legal bases to process the personal information we collect. Our legal basis for processing this personal information depends on the personal information concerned and the specific context in which we process it. We will normally collect personal information only where we need the personal information to perform a contract (e.g. to provide our Services), where the processing is in our legitimate interests and not overridden by your data protection interests or fundamental rights and freedoms, or where we have your consent. In some cases, we may also have a legal obligation to process personal information.

International Data Transfers and Storage

In order for us to operate and provide our Sites and Services globally, the personal information we collect may be transferred or accessed in various countries, including the United States of America. If you are located in the European Economic Area (“EEA”), Switzerland, or the United Kingdom (“UK”), please note that we may transfer information, including personal information, to a country and jurisdiction that offers a level of protection that may, in certain instances, be less protective of your personal information than the jurisdiction you typically reside in.

In the event that personal information is transferred outside of the EEA, Switzerland, or the UK to a country which is not subject to an adequacy decision by relevant regulators or considered adequate as determined by applicable laws, we will take steps to ensure the personal information is protected (e.g., by implementing approved Standard Contractual Clauses or relying on other data transfer mechanisms as available under applicable laws).

Additionally, Mattermost complies with the EU-U.S. Data Privacy Framework, the UK Extension to the EU-U.S. Data Privacy Framework, and the Swiss-U.S. Data Privacy Framework with regard to the processing of personal information received from the European Union (“EU”), UK, and Switzerland in reliance on the same. More information about Mattermost’s compliance can be found below in the “Data Privacy Framework” section of this Privacy Policy.

Retention of Personal Information

We retain the personal information we collect for as long as we need to provide our Sites and/or Services, or as required to comply with our legal obligations. After such time, we will delete, de-identify, or aggregate this information within 60 days, unless otherwise required by law.

If you have an account on Mattermost Sites or Services, we will retain your information for as long as your account is active or as needed to perform our contractual obligations, provide our Sites or Services to you, comply with legal obligations, resolve disputes, preserve legal rights, or enforce our agreements. We will delete, de-identify, or aggregate this information to the extent possible once it is no longer necessary to fulfill the purposes for which it was collected and processed.

Depending on the Services plan, Customers may be able to customize their retention settings for end user information such that they are different than Mattermost’s standard data retention practices. Customers may also apply different settings to messages, files, or other types of Customer Data. The deletion of Customer Data and other use of the Services by Customer may result in the deletion and/or de-identification of certain personal information and other information.

European Privacy Rights

Individuals in the EU, EEA, or the UK may have certain rights with respect to personal information processed through the Sites and Services. If your personal information was submitted to us by a Customer or your account is controlled by a Customer, then please contact the applicable Customer directly to learn about the rights you may have. Otherwise, please complete our request form to exercise any of the below rights.

Subject to certain exceptions and limitations, you may have the right:

to request information regarding the processing of your personal information by us;
to obtain the rectification of any inaccurate personal information stored by us or completion of such information;
to obtain the erasure of your personal information stored by us;
to obtain the restriction of processing of your personal information;
to receive your personal information that you have provided to us in a structured, commonly used and machine-readable format or to demand transmission to another controller;
to withdraw your consent once given to us at any time.

In addition to the above-listed rights, you may also have the right to lodge a complaint with your local data protection authority. Further information about how to contact your local data protection authority is available at https://ec.europa.eu/justice/data-protection/bodies/authorities/index_en.htm.

U.S. State Privacy Rights

Mattermost Community and forum participants who are residents of certain states may have rights under state privacy laws regarding personal information we process about them. Additionally, Mattermost Customers, visitors to our Sites, and other business contacts of Mattermost (collectively, our “Business Contacts”) who are California residents have rights under the California Consumer Privacy Act (“CCPA”) regarding personal information we collect about them. This section contains disclosures required by state privacy laws and explains the rights available under these laws.

However, this section does not cover personal information processed to provide our Services because we process such information on behalf of our Customers as a “service provider” or “processor.” To learn more about the rights that may be available to you as an end user of the Services under state privacy laws, like the CCPA, please visit our Customers’ privacy policies.

Personal Information We Collect and Disclose. In the past 12 months, we collected and disclosed the below categories of personal information about Mattermost Community and forum participants and our Business Contacts.

Personal and online identifiers (such as first and last name, email address, or unique online identifiers);
Record-keeping information (such as address);
Commercial or transactions information (such as records of products or services obtained or considered);
Internet or other electronic network activity information (such as interactions with Mattermost’s Sites, emails, applications, and/or advertisements);

Other information about you that is linked to the personal information above.

Why We Collect, Use, and Disclose Personal Information. We collect, use, and disclose personal information for our business and commercial purposes described in the “Information We Collect and How We Use It” and the “Information We Share with Third Parties and For What Purposes” sections of this Privacy Policy above. We do not use or disclose personal information for profiling in furtherance of decisions that produce legal or similarly significant effects concerning you.

Recipients of Personal Information. We may disclose each category of personal information that is described in this “State Privacy Rights” section to the categories of third parties described in the “Information We Share with Third Parties and For What Purposes” section of this Privacy Policy above.

While we do not sell the personal information we collect for money, we may allow certain third parties to collect personal information through our Sites in ways that may be viewed as “sales” under certain state privacy laws. This includes sharing such personal information for interest-based advertising purposes (also known as “cross-context behavioral advertising” or “targeted advertising”) by allowing third-party advertising providers to collect data on our Sites as described above under “Digital Advertising and Analytics” section of this Privacy Policy.

Your Rights. Residents of certain states may have certain rights with respect to the personal information collected by businesses like Mattermost. If you are a resident of one of these states, you may be able to exercise the following rights regarding your personal information, subject to certain exceptions and limitations:

The right to access a copy of the specific pieces of personal information that we have collected about you.
The right to request that we delete the personal information we have collected from you.
The right to request that we correct inaccurate personal information we maintain about you.
In some states, the right to obtain the categories of third parties to which we disclosed your personal information. In other states, the right to obtain a list of the third parties to which we disclosed personal information.
The right to confirm whether we are processing personal information about you, and in some states, the right to obtain the categories of personal information we process.
In California, the right to know the categories of personal information we collect, use, disclose, and share about you, the categories of sources from which we collected your personal information, our purposes for collecting or sharing your personal information, the categories of your personal information that we have either shared or disclosed for a business purpose, and the categories of third parties to which we have shared or disclosed personal information.
The right to opt out of our sales, including sharing of your personal information for interest-based advertising purposes.
The right not to receive discriminatory treatment for the exercise of the above privacy rights.

While some state privacy laws provide an opt-out opportunity for certain uses or disclosures of “sensitive personal information”, Mattermost uses and discloses such information only for purposes permitted by these laws that do not require an opt-out opportunity.

To exercise any of the other above rights other than the “right to opt out”, please complete our request form.

To exercise the “right to opt out”, please visit our Sites with Global Privacy Control (“GPC”) enabled. Our Sites recognize GPC signals as a way to opt out of sharing personal information for interest-based advertising purposes, as well as to opt out of “sales” under state laws. You can activate GPC by implementing a browser or extension that offers this control. GPC is a third-party tool. More information and instructions on implementing this tool are available here. You must implement GPC on each browser or device where you want to opt out.

Depending on your state, if you have submitted a request that you believe we have not fulfilled, you may contact us to appeal our decision by sending an email with the subject line “Appeal” to [email protected].

Verification Process and Required Information. For certain types of requests, we may need you to provide additional information to verify your identity or understand the scope of your request, although you will not be required to create an account with us to submit a request or have it fulfilled. For all requests other than opt-out requests, we will require you to provide, at a minimum, your name and email address. We will verify your request by comparing information in your request to personal information we have collected about you.

Authorized Agent. You may designate an authorized agent to make a request on your behalf by submitting a written, signed permission to [email protected]. Alternatively, an authorized agent with power of attorney can make a request for you.

Minors. We do not knowingly sell, share, or process for interest-based advertising the personal information of minors under 16 years of age.

Third-Party Links and Tools

This Privacy Policy does not apply to any third-party websites, services, integrations, or applications, even if they are accessible through our Sites and/or Services. This Privacy Policy only applies to our Sites and Services, so when you follow links to other websites you should read those separate and independent privacy policies to learn about their data practices. We have no responsibility or liability for the content and activities of these linked sites, or for any third-party websites, services, integrations, or applications.

The Sites and/or Services may also include integrated tools or “plug-ins,” such as machine learning, artificial intelligence, or social networking tools offered by third parties. If you use these tools to share personal information or you otherwise interact with these features on the Sites or Services, those third parties may collect information about you and may use and share such information in accordance with their privacy policies, and as applicable, your account settings.

Your interactions with third-party companies and your use of their features are governed by the privacy policies of the companies that provide those features. We encourage you to carefully read the privacy policies of any accounts you create and use.

Your Choices

To opt out of our email marketing, you can use the link provided at the bottom of each marketing message. If you opt out of our email marketing, we will still send you messages related to our transactions and relationship with you, such as order confirmations.

Data Privacy Framework

Mattermost complies with the EU–U.S. Data Privacy Framework (“EU-U.S. DPF”), the UK Extension to the EU-U.S. DPF, and the Swiss–U.S. Data Privacy Framework (“Swiss-U.S. DPF”) as set forth by the U.S. Department of Commerce (collectively, the “Frameworks”). Mattermost has certified to the U.S. Department of Commerce that it adheres to the EU-U.S. Data Privacy Framework Principles (“EU-U.S. DPF Principles”) with regard to the processing of personal information received from the European Union in reliance on the EU-U.S. DPF and from the UK (and Gibraltar) in reliance on the UK Extension to the EU-U.S. DPF.
