Slack Supplemental Terms | Legal

·Last updated: 27th February 2026

·The Salesforce Main Services Agreement ('MSA') and these Slack Supplemental Terms ('Supplemental Terms') are legally binding and govern your acquisition and use of Slack. These Supplemental Terms apply in addition to the MSA and form an integral part of the MSA (together, the MSA and Supplemental Terms are the 'Slack Terms'). Capitalised terms used but not defined in these Supplemental Terms have the meanings given to them in the MSA. 'SFDC' means the applicable Salesforce entity, as defined in the MSA, except as modified herein for online orders of Slack Services. Additional information related to the Slack Services may be found in the Documentation at https://sfdc.co/ptd. For the avoidance of doubt, the MSA takes precedence over the Documentation.

·Slack search, learning and artificial intelligence

·SFDC may access Customer Data in Slack for the following reasons, and Customer instructs SFDC to process its Customer Data for such purposes:

1to train models for use by the services and features that Customer has access to;

2to improve services and features that Customer has access to;

3to conduct research and development of products that Customer will have access to without additional cost;

4as otherwise provided in the MSA between SFDC and Customer.

·Customer retains all ownership of its Customer Data and SFDC retains all ownership in and to aggregated machine learning results.

·For more information about our practices, including instructions on how to opt out, visit our privacy principles page.

·Generative AI

·The Services contain features that use generative AI technology that may be provided by one or more third parties as listed in the Trust and Compliance Documentation applicable to the Services. This Documentation provides information and product requirements specific to these generative AI features and providers, including applicable third-party acceptable use policies with which the Customer must comply when using the generative AI technology. Due to the nature of generative AI, the output that it generates may be unpredictable, and may include inaccurate or harmful responses. Before using any generative AI output, the Customer is solely responsible for reviewing the output for accuracy, safety, and compliance with applicable laws and third-party acceptable use policies. The Customer assumes all responsibility for output generated by the Services and, as between SFDC and the Customer, such output is Customer Data.

·Multiple Infrastructure

·Services that interoperate between the Slack services and Salesforce services, including Salesforce Channels, are provided on one or more separate infrastructure(s) as described in the Infrastructure and Subprocessor Documentation and the Slack services' and Salesforce services' infrastructures may differ with respect to privacy and security protections and/or be hosted in different physical locations and are further described in the Salesforce Trust and Compliance Documentation. These Slack services interface with 'Interoperable (but not Authorised)' Salesforce products and features, and therefore the Customer acknowledges that Customer Data is shared outside the Slack Services FedRAMP authorisation boundary.

·Publicity

·Customer grants SFDC the right to use Customer's company name and logo as a reference for marketing or promotional purposes on SFDC's websites and in other public or private communications with existing or potential Slack customers, subject to Customer's standard trademark usage guidelines as provided to SFDC from time to time.

·SFDC contracting entity, notices, governing law and venue

·For an online order of Slack Services (a Slack subscription purchased via the Slack website), the following applies in place of the 'SFDC Contracting Entity, Notices, Governing Law, and Venue' section in the MSA:

·The SFDC entity entering into the Slack Terms, the address to which Customer should direct notices under the Slack Terms, the law that will apply in any dispute or lawsuit arising out of or in connection with the Slack Terms, and the courts that have jurisdiction over any such dispute or lawsuit, depend on where Customer is domiciled.

·Changes to terms

·We may make changes to these Supplemental Terms from time to time. If we make a material change to these Supplemental Terms, we will provide Customer with reasonable notice prior to the change taking effect. Customer understands and agrees that use of the Slack Services after the date on which these Supplemental Terms have changed will constitute acceptance of the updated Supplemental Terms.
