Mattermost Privacy Policy

Effective Date: December 23, 2022

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, including information that directly or indirectly identifies an individual (“personal information”), 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. If the Customer permits, Mattermost can collect limited service and usage data like error and diagnostics information, security alerts, and log file reports associated with device identifiers. We refer to this information as “telemetry data,” and it does not include any end user personal identifiers or message contents. Please see telemetry data for more information. Our Customers can choose to opt out of the usage data ping through the admin dashboard on the self-hosted products.

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.

If a Customer chooses to enable push notification services for a self-hosted/on-premises product, then we will additionally collect personal information about end users to support notifications. When push notifications are enabled, we use and disclose the related 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.

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”)

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 also controls and manages any third party services they use in conjunction with the Services. 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.

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

With service providers, subcontractors, partners, vendors, consultants, and others that help us with any of the purposes in this Privacy Policy, including by performing services on our behalf such as processing payments, sending email, providing back-office services, or measuring site traffic. These service providers are not permitted to use the information collected on our behalf except to help us conduct and improve our business.
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;

With your consent, our Customer’s consent, or as otherwise disclosed at the time of data collection or sharing.

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/. As described below in the “California Privacy Rights” section of this Privacy Policy, California residents (such as our Customers and website visitors) also have a right under California law to opt out of sharing of personal information for interest-based advertising (also known as “cross-context behavioral advertising”). This right can be exercised by using the Webchoices and Google ad tracking tools described above.

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 you provide to us or that 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, Switzerland, or the United Kingdom, 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 European Economic Area, Switzerland, or the United Kingdom 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, while Mattermost remains self-certified under the EU-U.S. Privacy Shield and Swiss – U.S. Privacy Shield, we are not relying on these frameworks for transfers of personal information. To see more information about our responsibilities under Privacy Shield, please see https://mattermost.com/privacy-shield. To learn more about the Privacy Shield Program, please see https://www.privacyshield.gov/welcome.

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 European Union, European Economic Area, or the United Kingdom 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 contact us at [email protected] 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 http://ec.europa.eu/justice/data-protection/bodies/authorities/index_en.htm.

The provision of personal information is neither a statutory nor contractual requirement nor a requirement necessary to enter into a contract. You are not obliged to provide personal information. There are no consequences resulting from failure to provide such information. We also do not process personal information for the purpose of automated decision-making.

California Privacy Rights for Business Contacts

If you are a California resident who is a Mattermost Customer, a visitor to our Sites, a Mattermost community member or contributor, or another business contact of Mattermost (collectively, our “Business Contacts”), this section contains disclosures required by the California Privacy Rights Act (“CPRA”) and applies only to “personal information” we process about you that is subject to the CPRA.

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 CPRA, please visit our Customers’ privacy policies.

If you are a California resident who is our Business Contact, you may exercise the following rights regarding your personal information, subject to certain exceptions and limitations:

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.

To exercise any of the above rights, please contact us using the following information and submit the required verifying information, by email at [email protected].

Verification Process and Required Information. Note that we may need to request additional information from you 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. We will require you to provide, at a minimum, your name, business email address, and business phone number.

Third-Party Links and Websites

This Privacy Policy does not apply to any third-party websites, services, or applications, even if they are accessible through our Sites and/or Services.

We have no responsibility or liability for the content and activities of these linked sites.

The Sites also include integrated social media tools or “plug-ins,” such as 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, those companies may collect information about you and may use and share such information in accordance with your account settings, including by sharing such information with the general public.

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.

For choices we offer to California residents who are our Customers or other business contacts, please see the “Your California Privacy Rights” section above.

Changes to our Privacy Policy

Your continued use of the Sites and Services after an updated Privacy Policy is posted constitutes your consent to the revised Privacy Policy.

Mattermost has subscribed to the EU – U.S. Privacy Shield Framework and Swiss – U.S. Privacy Shield Framework (collectively, “Privacy Shield”) as set forth by the U.S. Department of Commerce, regarding the collection, use, and retention of personal information transferred from the European Union, the United Kingdom and/or Switzerland as applicable to the United States.

(1) Notice, (2) Choice, and (3) Accountability for Onward Transfer of Personal information

Mattermost is required to take certain steps when transferring personal information received from the European Union and Switzerland to third parties (such as including necessary contractual provisions in our third-party contracts).

(6) Access

Our Privacy Policy explains how you may request access to review, correct or delete your personal information that we maintain about you by sending a written request to [email protected].

Mattermost has also committed to cooperate with EU data protection authorities (DPAs) and the Swiss Federal Data Protection and Information Commissioner (FDPIC) by complying with the advice given by such authorities with regard to human resources data transferred from the EU in the context of the employment relationship with Mattermost. If you do not receive timely acknowledgment of your complaint from us, or if we have not addressed your complaint to your satisfaction, you have available to you, your national European Data Protection Board (EDPA) to file complaints about your information in Mattermost’s custody. Please contact the EU DPAs for more information or to file a complaint. To find your national EDPA, please refer to this web site https://edpb.europa.eu/about-edpb/board/members_en. The services of EU DPAs are provided at no cost to you.

In certain circumstances, the Privacy Shield Principles provides the right to invoke binding arbitration to resolve complaints not resolved by other means, as described in Annex I to the Privacy Shield Principles.

Mattermost is subject to the investigatory and enforcement powers of the Federal Trade Commission and/or the Department of Transportation in the case of any failure to comply with the Privacy Shield.
