About Stack Overflow for Teams Integration with Slack

Stack Overflow Limited (“we” or “us”) takes the privacy and security of personal information seriously. This Privacy Notice explains who we are and how we collect, use, disclose, and safeguard your personal information when you, your organisation, authorised user or team administrators (“you”) use Stack Overflow for Teams Slack Integration (Slack Integration or the “Application”). It also explains your rights in relation to your personal information and how to contact us.

Stack Overflow for Teams is a private, secure home for your team’s questions and answers.

Slack Technologies Inc (Slack) provides a collaborative platform for teams. Stack Overflow has teamed up with Slack to provide an integrated functionality, Stack Overflow for Teams Slack Integration , that facilitates collaboration across the 2 platforms.

How does it work?

Organisations that are signed up with Stack Overflow for Teams can install and authorize an integration to use an integrated version of Stack Overflow for Teams.

Our Slack integration allows your organization to connect its internal communication tool with its internal knowledge repository. The integration lets you:

  • Search through your Team's content to find answers to your most pressing questions.
  • Stay up-to-date on your Team's latest answers and information with automated notifications.
  • Capture the questions and answers that quickly get lost in your Team's chat.

Stack Overflow as Controller

Stack Overflow is the controller for certain personal information that it holds about your organisation such as names and contact details of administrators, billing information, geo location, IP address and other information gathered from the App. Some of this data may be held by us as independent controller while your organisation may be controller for some of it.

Your organisation (Customer), is the controller for any personal information processed within the App following the integration. As the controller, it is the Customer’s responsibility to comply with all relevant data protection laws and regulations, including but not limited to: informing any authorised users and teams within your organization about the collection and processing of their data in an appropriate privacy notice; having a lawful basis for collecting and processing data, including where required, obtaining necessary consent. Please review your organisation’s privacy policy for more information on how your personal data will be used and how you can exercise your rights.

Stack Overflow as Processor

When you choose to complete the Slack integration with Stack Overflow for Teams, Stack Overflow acts as processor in connection with any personal information that it processes as part of the service it provides.
