Android phone without Google account?

Hi all,

Corona tracing apps that use Google’s API require Google’s Play Services.

Is there any information about what data is generally sent to Google when you run an Android phone without Google account?

Nobody knows, it’s the nature of proprietary software. We know that Google lies about what data it shares, see the recent fraud lawsuit in Arizona:

To be sure what data is being shared, you need to use free software only.

For the time beeing, I’d like to use a Corona tracing app, so replicant is not an option at the moment.
