To learn more about exercising your California privacy rights, please review the ‘California privacy rights’ section below.
Information we collect and receive
Slack will collect and receive information through operating the Services and Websites, and through other interactions with Slack. Such information will include Customer Data and other information and data (‘Other Information’) in a variety of ways:
- Customer Data. Customers or individuals granted access to a Workspace by a Customer (‘Authorised Users’) routinely submit Customer Data (such as messages, files or other content submitted through Services accounts) to Slack when using the Services.
- Other Information. Slack also collects, generates and/or receives the following categories of Other Information:
- Workspace and account information: To create or update a Workspace account, you or our Customer (e.g. your employer) supply Slack with an email address, phone number, password, domain and/or other account set-up details (for more detail on Workspace creation, click here. In addition, Customers that purchase a paid version of the Services provide Slack (or its payment processors) with billing details such as credit card information, banking information and/or a billing address.
- Usage information:
- Services metadata. When an Authorised User interacts with the Services, metadata is generated that provides additional context about the way that an Authorised User uses the Services. For example, Slack logs the Workspaces, channels, people, features, content and links that you view or interact with, the types of files shared and what Third-Party Services are used (if any).
- Log data. As with most websites and technology services delivered over the Internet, our servers automatically collect information when you access or use our Websites or Services and record it in log files. This log data may include your Internet Protocol (IP) address, the address of the web page that you visited before using the Website or Services, browser type and settings, the date and time that the Services were used, information about browser configuration and plugins, and your language preferences.
- Device information. Slack collects information about devices accessing the Services, including type of device, what operating system is used, device settings, application IDs, unique device identifiers and crash data. Whether we collect some or all of this Other Information often depends on the type of device used and its settings.
- Location information. We receive information from you, our Customers and other third parties that helps us to approximate your location. We may, for example, use a business address submitted by your employer (who is our Customer) or an IP address received from your browser or device to determine approximate location to assist with localisation or for security purposes.
- Third-Party Services information: A Customer can choose to permit or restrict Third-Party Services for its Workspace and Slack can receive personal data from such Third-Party Services. Typically, Third-Party Services are software that integrate with our Services, and a Customer can permit its Authorised Users to enable and disable these integrations for its Workspace (for more details on third-party application management, settings and permissions, click here). Slack may also develop and offer Slack applications that connect the Services with a Third-Party Service. Once enabled, the provider of a Third-Party Service may share certain information with Slack. For example, if a cloud storage application that you are using is enabled to permit files to be imported to a Workspace, we may receive the user name and email address of Authorised Users, along with additional information that the application makes available to Slack to facilitate the integration. Authorised Users should check the privacy settings and notices in these Third-Party Services to understand what data may be disclosed to Slack. When a Third-Party Service is enabled, Slack is authorised to connect and access Other Information made available to Slack in accordance with our agreement with the provider of the Third-Party Service and any permission(s) granted by our Customer (including by its Authorised User(s)). Examples of information which Slack may receive in this manner include whether you successfully created a new account or interacted with a third-party application in a way that is attributable to Slack usage activity. We do not, however, receive or store passwords for any of these Third-Party Services when connecting them to the Services. For more information on Slack’s interaction with Third-Party Services, click here.
- Contact information: In accordance with the consent process provided by your device or other third-party API, any contact information that an Authorised User chooses to import (such as importing an address book to find colleagues and Slack Connect contacts or calendar from a device or API), forward or upload to the Services (for example, when sending emails to the Services) is collected when using the Services.
- Third-party data: Slack may receive data about organisations, industries, lists of companies that are customers, website visitors, marketing campaigns and other matters related to our business from parent corporation(s), affiliates and subsidiaries, our partners or others that we use to make our own information better or more useful. This data may be combined with Other Information that we collect and might include aggregate-level data, such as which IP addresses correspond to postcodes or countries. Or it might be more specific: for example, how well an online marketing or email campaign performed.
- Audio and video metadata: Slack may receive, capture and store metadata derived from your use of features such as Slack huddles or clips, and additional related data such as data regarding the date and time of your Slack huddle and the Authorised User that you connected with.
- Additional information provided to Slack: We also receive Other Information when submitted to our Websites or in other ways, such as responses or opinions that you provide if you participate in a focus group, contest, activity or event, feedback that you provide about our products or services, information that you provide if you apply for a job with Slack, enrol in a certification programme or other educational programme hosted by Slack or a vendor, request support, interact with our social media accounts or otherwise communicate with Slack.
Generally, no one is under a statutory or contractual obligation to provide any Customer Data or Other Information (collectively “Information”). However, certain Information is collected automatically and if some Information, such as Workspace setup details, is not provided, we may be unable to provide the Services.
How we process your information and our legal bases for doing so
Customer Data will be used by Slack in accordance with a Customer’s instructions, including to provide the Services, any applicable terms in the Customer Agreement, a Customer’s use of Services functionality and as required by applicable law. Slack is a processor of Customer Data and the Customer is the controller. The Customer may, for example, use the Services to grant and remove access to a Workspace, assign roles and configure settings, access, modify, export, share and remove Customer Data, and otherwise apply its policies to the Services.
Slack uses Other Information to operate our Services, Websites and business. More specifically, Slack uses Other Information for the following purposes:
Compliance with a legal obligation:
Slack processes Other Information when we comply with a legal obligation including, for example, to access, preserve or disclose certain information if there is a valid legal request from a regulator, law enforcement or others. For example, a search warrant or production order from law enforcement to provide information in relation to an investigation, such as your profile picture or IP address.
We use Workspace and account information, usage information, cookie information, Third-Party Services information, contact information, third-party data, audio and video metadata, and additional information provided to Slack for compliance with a legal obligation.
We rely on our legitimate interests or the legitimate interests of a third party where they are not outweighed by your interests or fundamental rights and freedoms (‘legitimate interests’).
We use Workspace and account information, usage information, cookie information, Third-Party Services information, contact information, third-party data, audio and video metadata, and additional information provided to Slack for the following legitimate interests:
- To provide, update, maintain and protect our Services, Websites and business.
This includes the use of Other Information to support delivery of the Services under a Customer Agreement, prevent or address service errors, security or technical issues, analyse and monitor usage, trends and other activities, or at an Authorised User’s request.
- It is in our and your interests to provide, update, maintain and protect our Services, Websites and business.
- To develop and provide search, learning and productivity tools and additional features.
Slack tries to make the Services as useful as possible for specific Workspaces and Authorised Users. For example, we may:
- improve search functionality by using Other Information to help determine and rank the relevance of content, channels or expertise to an Authorised User;
- make Services or Third-Party Service suggestions based on historical use and predictive models;
- identify organisational trends and insights;
- customise a Services experience; or
- create new productivity features and products.
- It is in our interest and in the interest of Customers and Authorised Users to continuously improve and develop the customer support that we provide.
- To investigate and help prevent security issues and abuse.
We may use a variety of tools such as device fingerprinting to prevent issues and abuse. We may process, including in an automated fashion, Other Information to better understand how Slack is used or to prevent spam or abuse.
- It is in our interest to keep the Services secure and to detect, prevent and address abuse (such as spam) and to investigate and take action in respect of suspicious activity on the Services.
- To aggregate or de-identify information.
In some cases, we aggregate or de-identify information that we have associated with you and use the resulting information, for example, to improve the Services.
- It is in our interest to research and improve the Services;
- It is in the interests of Customers and Authorised Users to practice data minimisation and privacy by design in respect of their information.
- Share information with others, including law enforcement, and to respond to legal requests.
- It is in our interest and the interest of the general public to prevent and address fraud, unauthorised use of Slack, violations of our terms or other harmful or illegal activity; to protect ourselves, our users or others, including as part of investigations or regulatory inquiries; or to prevent death or imminent bodily harm.
- Transfer, store or process your information outside the European Economic Area.
As the Websites and Services operate globally, with Customers around the world, we need to share information that we collect globally. We carry out necessary transfers outside the European Economic Area, including to Australia, Canada, Japan, India, South Korea and the United States, to provide, update, maintain and protect our Services, Websites and business.
For more information, review the ‘International data transfers’ section below.
- It is in our and your interests to provide, update, maintain and protect our Services, Websites and business.
We use Workspace and account information, Third-Party Services information, third-party data and additional information provided to Slack for the following legitimate interests:

If you contact us, we may use your Other Information to respond.
- It is in our, our Customers’ and Authorised Users’ interests to facilitate communication (for example to answer questions from Customers).
- To send service emails and other communications.
For example, we may:
- send you service, technical and other administrative emails, messages and other types of communications; or
- contact you to inform you about changes in our Services, our Services offerings and important Services-related notices, such as security and fraud notices. These communications are considered part of the Services, and you may not opt out of them. It is in our Customers’ and Authorised Users’ interests to address service-related issues.
We use Workspace and account information and usage information for the following legitimate interests:
- For billing, account management and other administrative matters.
Slack may need to contact you for invoicing, account management and similar reasons and we use account data to administer accounts and keep track of billing and payments.
- It is in our interest to facilitate the effective provision and administration of the Websites and Services.
We use Workspace and account information, usage information, cookie information, Third-Party Services information, third-party data and additional information provided to Slack for the following legitimate interests:
- To send marketing emails and other communications.
We sometimes send emails about new product features, promotional communications or other news about Slack. These are marketing messages, so you can control whether you receive them. If you have additional questions about a message that you have received from Slack, please get in touch through the contact mechanisms described below.
- It is in our interest to promote the Websites and Services and send our direct marketing.
How we share and disclose information
This section describes how Slack may share and disclose Information, as described in the section entitled ‘Information we collect and receive’ above. Customers determine their own policies and practices for the sharing and disclosure of Information to third parties. Slack does not control how a Customer or any third party chooses to share or disclose Information.
- The Customer’s instructions. Slack may share and disclose Information in accordance with a Customer’s instructions and with appropriate consent, including any applicable terms in the Customer Agreement and the Customer’s use of Services functionality and in compliance with applicable law and legal process. Some sharing at a Customer’s request may incur additional fees.
- To enable Slack to follow our Customers’ instructions, Slack provides several administrator controls to allow Customers to manage their Workspaces. For example, we follow our Customers’ instructions to enable or disable Authorised Users’ use of various features of the Services, such as clips or Slack huddles, channel posting permissions, the sharing and visibility of direct messages including files, or whether and how Authorised Users can connect with other organisations’ Workspaces through Slack Connect.
- We also follow Customer and Authorised User instructions on how an Authorised User’s profile may be displayed within a Customer’s Workspace or when shared through Slack Connect or other features.
- Customers may also provide their Authorised Users with the ability to adjust the audience and visibility of certain Customer Data. To learn more, visit our Help Centre to understand what choices and settings are available.
- Displaying the Services. When an Authorised User submits Information, it may be displayed or discoverable to other Authorised Users in the same or connected Workspaces or Slack Connect instances. For example, an Authorised User’s email address may be displayed with their Workspace profile, or other profile and organisational information may be displayed to Authorised Users. Please consult the Help Centre for more information on Services functionality.
- Collaborating with others. The Services provide different ways for Authorised Users working in independent Workspaces to collaborate, such as Slack Connect or email interoperability. Information, such as an Authorised User’s profile and organisational information, may be shared, subject to the policies and practices of the Workspace(s) that you use. For example, depending on the settings of your Workspace, to enable connections with other Authorised Users, your profile may be shared or searchable or discoverable by Authorised Users or other users outside of the Workspace(s) that you belong to, or shared via email when you invite an Authorised User or other user to collaborate via Slack Connect. In many instances, Slack includes either administrator controls or user controls, depending on the use case, with respect to external collaboration. Authorised Users may also decide to expand the visibility of certain content and Customer Data, such as files.
- Customer access. Owners, administrators, Authorised Users and other Customer representatives and personnel may be able to access, modify or restrict access to Information. This may include, for example, your employer using features of the Services to access or modify your profile details, or to export logs of Workspace activity. For information about your Workspace settings, please visit https://slack.com/account/settings.
- Third-party service providers and partners. We may engage third-party companies or individuals as service providers or business partners to process Information and support our business. These third parties may, for example, provide virtual computing and storage services, assist Slack with verifying Owners and Customers, or we may share business information to develop strategic partnerships with Third-Party Service providers to support our common customers. In this respect, depending on the Third-Party Service provided, Slack may share your Information. Additional information about the subprocessors that we use to support delivery of our Services is set forth at Slack subprocessors.
- Third-Party Services. A Customer may enable, or permit Authorised Users to enable, Third-Party Services. We require each Third-Party Service provider to disclose all permissions for information accessible through the Services, but we do not guarantee that they do so. When Third-Party Services are enabled by a Customer or an Authorised User, Slack may share Information with Third-Party Services. Third-Party Services are not owned or controlled by Slack and third parties that have been granted access to Information may have their own policies and practices for its collection, use and sharing. Please check the permissions, privacy settings and notices for these Third-Party Services, or contact the provider if you have any questions.
- Forums. The Information that you choose to provide in a community forum, including personal data, will be publicly available.
- Organisers and sponsors of events/webinars. If you attend an event or webinar organised by Slack, we may share your profile and organisational information with the event or webinar sponsors when you register, have your badge scanned or join a breakout room. If required by applicable law, you may consent to such sharing via the registration form or by allowing your attendee badge to be scanned at a sponsor booth. In these circumstances, your information will be subject to the sponsors’ privacy statements. For more information, please refer to the terms provided when you register for such an event or webinar.
- Professional advisers. We may share your Information with professional advisers acting as service providers, processors, controllers or joint controllers – including lawyers, bankers, auditors and insurers who provide consultancy, banking, legal, insurance and accounting services, and to the extent we are legally obliged to share or have a legitimate interest in sharing your Information containing personal data.
- Corporate affiliates. Slack may share Information with our corporate affiliates, parents and/or subsidiaries.
- During a change to Slack’s business. If Slack engages in a merger, acquisition, bankruptcy, dissolution, reorganisation, sale of some or all of Slack’s assets or stock, financing, public offering of securities, acquisition of all or a portion of our business, a similar transaction or proceeding, or steps in contemplation of such activities, some or all of the Information described in the ‘Information we collect and receive’ section may be shared or transferred, subject to standard confidentiality arrangements.
- Aggregated or deidentified Data. We may disclose or use aggregated or de-identified Information for any purpose. For example, we may share aggregated or de-identified Information with prospects or partners for business or research.
- Law enforcement and regulators. If we receive a request for information, we may disclose Other Information if we reasonably believe that disclosure is in accordance with or required by any applicable law, regulation or legal process. Please review the Data request policy, Data request overview and Transparency report to understand how Slack responds to requests to disclose data from government agencies, law enforcement entities and other sources. This may at times include information that Slack Technologies, LLC processes on behalf of Slack Technologies Limited in its role as a subprocessor, including as pursuant to the terms of any data protection agreement between Slack and its Customers.
- To enforce our rights, prevent fraud and for safety. To protect and defend the rights, property or safety of Slack, its users or third parties, including enforcing its contracts or policies, or in connection with investigating and preventing illegal activity, fraud or security issues, including to prevent death or imminent bodily harm.
Slack will retain Customer Data in accordance with a Customer’s instructions (including to perform any applicable terms in the Customer Agreement and through the Customer’s use of Services functionality) and as required by applicable law. The Customer may customise its retention settings and, depending on the Services subscription, apply those customised settings at the Workspace level, channel level or other level. The Customer 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 the Customer may result in the deletion and/or de-identification of certain associated Other Information. For more detail, please review the Help Centre or contact the Customer.
Slack takes security of data very seriously. Slack works hard to protect Information that you provide from loss, misuse and unauthorised access or disclosure. These steps take into account the sensitivity of the Information that we collect, process and store, and the current state of technology. Slack has received internationally recognised security certifications. To learn more about current practices and policies regarding security and confidentiality of the Services, please visit our Security practices. Given the nature of communications and information processing technology, Slack cannot guarantee that Information during transmission through the Internet or while stored on our systems or otherwise in our care will be absolutely safe from intrusion by others. When you click a link to a third-party site, you will be leaving our site, and we don’t control or endorse what is on third-party sites.
Slack does not allow use of our Services and Websites by anyone younger than 16 years old, to the extent prohibited by applicable law. If you learn that anyone younger than 16 has unlawfully provided us with personal data, please contact us and we will take steps to delete such information.
International data transfers
Slack may transfer your Personal Data to countries other than the one in which you live, including transfers to the United States. To the extent that Personal Data is transferred abroad, Slack will ensure compliance with the requirements of the applicable laws in the respective jurisdiction in line with Slack’s obligations.
In particular, we offer the following safeguards if Slack transfers Personal Data from jurisdictions with differing data protection laws:
- European Commission’s Standard Contractual Clauses. Slack uses Standard Contractual Clauses approved by the European Commission (and the equivalent standard contractual clauses for the UK, where appropriate) for transfers to, among others, Australia, Canada, India, Japan, South Korea and the United States. Slack will transfer your Personal Data to facilitate the provision of the Services. A copy of our standard data processing addendum, incorporating the Standard Contractual Clauses, is available here, and a copy of the executed version of the Standard Contractual Clauses may be obtained by contacting us as described in the ‘Contacting Slack’ section below.
Data Protection Officer
To communicate with our Data Protection Officer, please email firstname.lastname@example.org.
Identifying the Data Controller and Processor
Data protection law in certain jurisdictions differentiates between the ‘controller’ and ‘processor’ of information. In general, the Customer is the controller of Customer Data. In general, Slack is the processor of Customer Data and the controller of Other Information. Different Slack entities provide the Services in different parts of the world.
- Slack Technologies Limited, an Irish company based in Dublin, Ireland, is the controller of Other Information and a processor of Customer Data relating to Authorised Users who use Workspaces established for Customers outside of the US and Canada.
- Slack Technologies, LLC, a US company based in San Francisco, California, is the controller of Other Information and a processor of Customer Data relating to Authorised Users who use Workspaces established for Customers in the US and Canada.
Individuals in the European Economic Area, the United Kingdom, Brazil and across the globe have certain statutory rights in relation to their personal data. Subject to any exemptions provided by law, you may have the right to request access to your personal information, as well as to seek to update, delete or correct this information. You can do this using the settings and tools provided in your Services account. If you cannot use the settings and tools, contact the Customer who controls your workspace for additional access and assistance. Please check https://slack.com/account/settings for Customer contact information.
To the extent that Slack’s processing of your Personal Data is subject to the General Data Protection Regulation or other applicable laws requiring a legal basis for processing Personal Data, such as the UK Data Protection Act and the Brazilian General Data Protection Act (Lei Geral de Proteção de Dados), Slack primarily relies on its legitimate interests, described above, to process your Personal Data. Where we rely on legitimate interests to process your Personal Data, you can object to that processing by contacting us as described in the ‘Contacting Slack’ section below. In response to your objection, we will stop processing your information for the relevant purposes unless we have compelling grounds in the circumstances or the processing is necessary in the context of legal claims. Slack may also process Other Information that constitutes your Personal Data for direct marketing purposes, and you have a right to object to Slack’s use of your Personal Data for this purpose at any time.
