1. What is a cookie?

We use cookies and other similar technologies (which include pixels, tags, web beacons, software development kits (“SDKs”) and local browser storage technologies) (collectively, “cookies”) on our Services. A cookie is a small file containing a unique identifier that is placed in the web browser of your computer or mobile device when you visit a website. SDKs are third-party software tools that are used in our mobile apps and allow us to understand how our apps are used and what actions occur in relation to the app, including when a Member signs up or logs in. A pixel (also sometimes called web beacon, or clear GIF) is a tiny piece of code, invisible to the user, placed on a webpage or in an email and used in combination with a cookie to link a given activity or impression back to the user.

Cookies enable operators of websites/apps to recognize your device and collect information from it when you interact with them. They use this information to understand how the website/app is being used, remember user preferences, and improve user browsing experience. Cookies are also used to make the advertising you see online more relevant to your interests. Find out more about the use of cookies on www.allaboutcookies.org.

2. What is a mobile advertising identifier?

Most major phones and tablets include a mobile advertising identifier (e.g., an IDFA on iOS and an ADID on Android) that is a unique device identifier that enables third parties to connect you to your activities across apps and websites, including Nextdoor. This is generally used for personalizing advertising and measurement of advertising campaigns.
