Is it possible to send a phone number to google analytics events?

Question

Python

I sent an event to Google Analytics from the site. In it, I link a specific visitor with his phone number if he called the company using call tracking. In fact, the use of personal data, the collection of which must be specified on the site, is not a problem, but I think Google will not ban this without explanation?

Answer 1

encrypt and send

Answer 2

Google prohibits transferring user information to GA: this applies to mail and phone numbers
Otherwise, get a ban
