Nothing that passes through HR is anonymous.
Ever.
Ever.
Ive been in orgs where HR was literally sleeping with head of sales, and had me fix phones with dickpics and BJ vids and etc btwn employees...
uh HR IS NOT YOUR FRIEND.
Do not confide in them, especially anything personal.
Also, if you have an IOS device - log into your apple account and confirm the devices tied to it.. HR will (in many SV orgs) attempt to add a device to your apple account to monitor you.
BYOD is a nightmare for personal privacy, and HR depts will use personal info against you.

EDIT: Just a reminder that Uber literally went after the medical records (HIPAA violations, at min.) to slander a person calling them out for sexual misconduct
"But I want to only have 1 number, and want to keep my own (naive yound tech employee says)"
You can take this device and just have yuour number on it...
You login to your apple ID on that device...
They read every text...

Do you recall when FB tried to make a phone...
THANK FUCKING GOD THAT FAILED.
uh... I was a new hire at FB when this tok place and they held a mtg and were talking about the phone, and the question was asked about what was thought of the new phone, and I misconstrued the mtg as being "open and connecting people" -- and I spoke to the product guy in the mtg, and I told him it was a POS. NOBODY liked my non-sycophantic behaviour... as I said that I had experienced it IRL with users and they all hated it...
That went over not-so-cromulently.

FB, even internally, is the quintessential "You cant get out of your own way..." company.
This comes off as more than just a little bit paranoid - HR can't just add devices to your iCloud account. It requires credentials and 2FA to do that for one thing, and it'd be illegal in most of the countries we're in to boot.
Good thing that such acts are *illegal* - that'll show'em.

FYI - KEEP YOUR PERSONAL SHIT PERSONAL.

One must develop a personal air-gap.
