Things you should know:
Enabling this Service keeps your Firefox web browsing activity private from your internet service provider, and most websites you visit, by encrypting and routing it through our partner Cloudflare’s network instead.
This Service protects most—but not all—of your web browsing: The Service only works in Firefox and for websites that communicate with your computer using TCP (Transmission Control Protocol). For example, it does not work for data exchanged on certain video conferencing services (such as Google Hangouts, Facebook Messenger, GoToMeeting) or on applications outside of Firefox (such as other apps on your device).

Technical data. Firefox sends Mozilla data about your device, operating system, version, and a unique identifier that Mozilla connects to your Firefox Account.
Interaction data. Mozilla receives data about when you install Firefox Private Network, when you use the service, and engagement with our surveys and Firefox.
Registration data. This service requires a Firefox Account, which sends Mozilla your email address, locale, and IP address. Learn more about Firefox Account data practices.
