Privacy Evaluation for Slack
Slack is a business communication service. According to Slack's policy, when an authorized user submits information, it may be displayed to other authorized users in the same or connected workspaces. In order to create or update a Workspace account, the user or their Customer (e.g., the user's employer) supplies Slack with an email address, phone number, password, domain and/or similar account details. Slack's security policy lists several security-related audits and certifications are applicable to the Slack services, and it uses encryption. It is unclear what obligations Slack has to children under 13 or 16 if use is not prohibited by law, or if Slack itself has knowledge a child is using its service.
According to Slack's policy, when an authorized user submits information, it may be displayed to other authorized users in the same or connected workspaces.

Slack's policy calls corporate users "Customers." Customers or individuals granted access to a workspace by a Customer (“Authorized Users”) routinely submit Customer Data to Slack when using the Services. Slack also collects, generates and/or receives other Information, including workspace and Account Information. For example, in order to create or update a Workspace account, the user or their Customer (e.g., the user's employer) supplies Slack with an email address, phone number, password, domain and/or similar account details. Slack's policy says they do not sell the personal information they collect and will not sell it without providing a right to opt out. The policy notes that third parties may, for example, provide virtual computing and storage services, or that Slack may share business information to "develop strategic partnerships" with third party service providers to support their common customers.
The Slack security policy explains that they place strict controls over their employees’ access to the data corporate customers and their users make available via the Slack services, and it also lists several security-related audits and certifications are applicable to the Slack services. Data is encrypted in transit and at rest while in storage, according to this policy. The policy notes that in the event of a security breach, Slack will promptly notify you of any unauthorized access to your Customer Data.
Slack's policy notes that to the extent prohibited by applicable law, Slack does not allow use of their services and websites by anyone younger than 16 years old. If a user learns that anyone younger than 16 has unlawfully provided Slack with personal data, Slack's policy asks that the user please contact them and they will take steps to delete such information. It is unclear what obligations Slack has to children under 13 or 16 if use is not prohibited by law, or if Slack itself has knowledge a child is using its service.
