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 welcomes you to the Network, the largest community of developers and technologists in the world, and invites you to participate in the community by sharing knowledge with your peers and colleagues.

This Privacy Notice is applicable to you when you interact with us on Stack Overflow for Teams (Free, Basic and Business).

ABOUT STACK OVERFLOW FOR TEAMS

Stack Overflow for Teams (Free, Basic, and Business ) (the "Product" or "Teams") is a software application tailored for sharing questions and answers within your company and is owned and operated by Stack Overflow. We offer various levels of the Product: Free, Basic, and Business. This privacy notice covers all of these Products. These Products allow you to participate in both (i) the Public Network and (ii) to post privately within your Company to share knowledge with your peers and colleagues. Stack Overflow for Teams allows you to share private content via authorized closed communities.

Here you will find details about the personal information we collect about you when you use the Stack Overflow for Teams Platform, how and why we collect it, how we use it, and how we keep it secure. This Privacy Notice also tells you about your rights, how you can exercise those rights, and how the law protects you.

Stack Exchange, Inc. is the controller responsible for your personal data.

Determining Controllers and Processors

We may process data in two ways; as processor, acting on behalf of your organization, or as controller, acting for our own purposes. This privacy notice covers our obligation as controller, but we also explain when we act as processor on behalf of your organization.

In accordance with our terms of service, when we provide the services to you on Stack Overflow for Teams, we act as processor, carrying out instructions on your behalf. In certain circumstances, we will also process data for our own purposes, as controller. More details are set out below.

Data we process on your behalf as processor

When we provide Teams services to our Customers, the Customer acts as the controller and Stack Overflow acts as the processor in respect of any personal data that is held or processed as a result. Any personal data that we process as part of the services will be on behalf of the Controller. Your organization retains the responsibility to comply with any applicable regulatory requirements, including issuing any privacy notices and obtaining consent, where required, for processing personal data. You should read your organization’s privacy notice to find out more about how your data is processed and how you can exercise your rights. We are also required by data protection laws to sign a Data Processing Addendum (DPA) with your organization before we process any personal data.

Stack Overflow as Controller

When you interact with us as a Teams customer, we will also collect and process certain information for our own purposes as controller. This includes personal data, such as billing information, names, telephone number, email address and other contact details of key contacts and authorized users.

This Privacy Notice describes the personal data that we collect about you as controller when you interact with us as a Teams customer; how and why we collect it, how we use it, and how we keep it secure and your data privacy rights.

WHAT INFORMATION DO WE COLLECT?

Account registration information as well as company or team affiliation information is displayed to authorized users of your Team.

In addition to account registration and company or team affiliation information, Stack Overflow collects certain application metadata for the purposes of maintaining and enhancing the Stack Overflow for Teams product and related services we provide. This metadata is only made available to Stack Overflow authorized personnel, and in some cases, authorized third parties, such as vendors, under a duty of confidentiality. Please see the table below for more information.

Sales and other contact information Names and contact details of key contacts and representatives

WHAT WE USE YOUR PERSONAL DATA FOR (PURPOSES)

Our collection of such content is solely to provide the Products and Services, and is provided pursuant to the applicable product terms such as private Network Terms. Stack Overflow personnel may not access such content except to the extent as may be required in response to a support request with your explicit permission, or when required for security or maintenance of the product or services. In such cases, Stack Overflow personnel will only access the minimum content necessary to resolve the issue and in accordance with the applicable product terms such as private Network Terms.

OUR LEGAL GROUNDS FOR USING YOUR PERSONAL DATA

We will only use your personal data when the law allows us to. We will use your personal data in the following circumstances:

  • Where we need to perform the contract we are about to enter into or have entered into with you. For example, when Customers purchase an Enterprise product, where you request a service from us, or where we need to set up your account or for billing purposes.
  • Where we have your consent. For example, where you have provided your consent to receive marketing emails from us or where you have given your consent to be contacted by a third party sponsor for an event you have participated in. You can withdraw your consent at any time. In the case of marketing emails, you can withdraw your consent by clicking on the "unsubscribe" link in the email you received.
  • Where we need to comply with a legal or regulatory obligation.
  • Where it is in our legitimate interests, including our commercial interests or a third party’s legitimate interest in using the personal information. Examples include when we carry out analysis to understand how our products are used and how we can improve them; carrying out marketing analyses to better understand your interests and preferences so that we can make our marketing more relevant to your interests and preferences. This includes when we promote our own products and services.

Whenever we rely on legitimate interests for processing, we ensure that we consider and balance our interests against the individual’s interests before processing. We do not use your personal data on the basis of legitimate interest for activities where individuals’ interests override our interests.

WHO DO WE SHARE YOUR PERSONAL INFORMATION WITH?
