This extension sends private data WHEREVER YOU TELL IT TO This extension doesn't send your data anywhere unless you have configured a server in the Google Admin Console or an equivalent platform for managing enterprise policy on Chromebooks. If you do configure a server via enterprise policy (which is the whole point of the extension) the extension will send: - a timestamp - your email address - your device's serial number - your local IPv4 and IPv6 address - your location (along with information about the accuracy and age of the location information) - your session duration to the configured server at the configured interval. If you don't control that server, you should understand the privacy implications of sending them data before you configure this extension. If you don't control that server, you should probably ask for a privacy policy from whoever does control the server. This extension does not send your data anywhere except to the server you have explicitly configured.
