About Stack Overflow

The Stack Overflow Network (also referred to herein as “Stack Overflow” or “Network”) is a set of related Internet sites and other applications for asynchronous collaboration and sharing knowledge, owned and operated by Stack Exchange, Inc. (“Stack Overflow”, “we” or “us”), a Delaware corporation.

Stack Overflow takes the privacy and security of personal information seriously. This Privacy Notice explains how we collect, use, disclose, and safeguard your personal information when you, your organization or team administrators (“you”) use Stack Overflow for Teams Enterprise (Enterprise or the “Application”). It also explains your rights in relation to your personal information and how to contact us. Stack Overflow’s Full Privacy Notice can be accessed via this link.

About Stack Overflow for Teams: Enterprise Integration

Stack Overflow has teamed up with Microsoft Teams to provide an integrated functionality for Enterprise customers. The integration facilitates collaboration and helps to enhance the business communication application through quick access to solutions, knowledge retention for future reuse, and awareness of new or updated information. The native Stack Overflow for Teams experience within your Microsoft Teams environment helps to reduce friction in the development process and minimizes the need to switch between applications.

How does it work?

Organizations that are signed up with Enterprise can install and authorize an integration to use Enterprise. Once installed and within the MS Teams App, you give your permission to complete the integration and activate any relevant teams and for any personal information on to be shared with any third parties we have integrated with to provide you with the functionality. You can withdraw your permission at any time, but if you do, you will no longer be able to access the App.

The Enterprise Integration allows you to:

  1. Search through your team's content to find answers to your most pressing questions.
  2. Search Enterprise from Microsoft Teams: Search Enterprise by @-mentioning the Enterprise bot in a channel with a message that starts with ‘search’ or chatting the Enterprise bot with a message that starts with ‘search’.
  3. Receive Microsoft Teams messages from Enterprise: Setup webhooks that provide notifications through Microsoft Teams as messages to a Microsoft Teams channel or chat.
  4. Stay up-to-date on your Team's latest answers and information with automated notifications.
  5. Share and preview content from your Private Q&A right within your Microsoft team
  6. Send data over the Internet.
  7. Access personal information on the active message, such as phone numbers, postal addresses, or URLs. The add-in may send this data to a third-party service. Other items in your mailbox can’t be read or modified.
  8. Capture knowledge for future use by converting a question from Microsoft Teams into a post within Stack Overflow for Teams
  9. Access knowledge from Stack Overflow for Team with a channel's tab or a user's personal app to reduce switching between applications

Stack Overflow as Processor

When you choose to complete the MS Teams integration with Enterprise, Stack Overflow acts as processor in connection with any personal information that it processes as part of the service it provides. Your organization (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 organization’s privacy policy for more information on how your personal data will be used and how you can exercise your rights.

Stack Overflow as Controller

Stack Overflow is the controller for certain personal information that it holds about your organization 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 organization may be controller for some of it.
