| 191 | When you visit our Network and sites or when you use our apps, we may collect personal data from you automatically using cookies or similar technologies. A cookie is a small file that can be placed on your device that allows us to recognize and remember you. We may place cookies on your device (with your consent, where applicable), as well as partner with third parties, including advertising partners, who may use cookies or other similar technologies to provide you with advertising based on your browsing activities and interests.

| 193 | 193 | **Tracking** |
| 194 | 194 | |
| 195 | 195 | Stack Overflow emails use Javascript for email tracking of opens, clicks, and unsubscribes or may contain a small, invisible, one pixel image which can be used to let us know when the email is opened or forwarded. If the email recipient has images enabled on their device, when the email is opened, a message (an automatic request) is sent to Stack Overflow's server requesting the image. That request is logged by Stack Overflow and tells us that the email has been opened. A similar process may be used in relation to links or attachments in the email, with a request being sent to Stack Overflow for the content that is accessible via the links or attachments, thus telling Stack Overflow that the link or attachment has been accessed. |
| 196 | 196 | |
| 197 | 197 | **Developer Survey** |
| 198 | 198 | |
| 199 | 199 | As the world's largest developer community, Stack Overflow publishes an annual Developer Survey to provide key insights into the developer community, as well as other surveys from time to time, some of which include demographic (e.g., gender, race, age, etc.) and certain personal information. Your participation in the Developer Survey as well as any other Stack Overflow survey is entirely voluntary. In order to provide meaningful insights into the developer community, Stack Overflow may collect sensitive data about you, including, but not limited to your gender, race, sexual orientation, immigration status, and your location. We consider this data to be among our most sensitive and have taken elevated measures to protect such data as well as to de-identify your name and other personal information from such data. We restrict such data within Stack Overflow on a privileged basis to only those that need to see it and while we may share your personal information with our third party providers for our research, we do so only after imposing contractual obligations of confidentiality on such third parties and only where necessary for limited research purposes. |
| 200 | 200 | |
| 201 | 201 | When we publish our surveys, they are published as a compilation of anonymized data. We may ask for your consent to contact you following completion of the surveys. |
