How your Device and Browser Protect your Info
CloudReady is designed, first and foremost, to maintain the experience you get from a Chromebook in as many ways as possible. This includes all of same privacy and security controls that you would have on a Chromebook to ensure your personal data is encrypted and protected on your CloudReady disk.
You use your Google/GSuite account to log in to, and sync settings onto, a CloudReady device. Google provides a useful resource for reviewing what applications, extensions, and utilities have various permissions and access to your Google/Chrome Account:
If you visit that link after using CloudReady, you will see that "CloudReady by Neverware" or "CloudReady free" is listed as an app that has full access to your user and permissions. You will also notice that "Google Chrome" is similarly listed (assuming that you use or have used Chrome on some other machine). This is a requirement for us to be able to authenticate you as a user, but does not indicate any access to your personal data.
How Neverware Protects your Info
Neverware does not use the above referenced profile for anything besides allowing login to Google's services. We do not use your Google account on your behalf, or collect or process any other information about individual users of CloudReady.
Neverware does track hardware data about the machines you run CloudReady on, as well as limited usage data about how often devices are turned on, logged in, or when special features like flatpaks are used. None of the data that we collect is tied to your personal identity.
We require this information in order to serve our Enterprise and Education customers, but if you prefer not to share this anonymous device information with us on the Home Edition you can visit the Settings menu to opt out starting in v66 of CloudReady.
