Hope this is the right place to ask. TikTok is blatantly using my data without permission, can I do anything?

So this issue is twofold:

First, TikTok has never asked for permission to use my location, there are no location tabs in settings, and there’s no location on/off switch in my phone settings either (I’m on Apple)

Second, this week I just started to get emails from TikTok. They’re all basic notifications like “so-and-so sent you a message” and things like that. However, I’ve never attached an email address to my TikTok. Ever. I never signed in with google or added it then took it away (sorry for weird wording, keyword stuff) from my account. It’s just never been there so I don’t know how they found it or why it’s suddenly being used.

This sounds like class action lawsuit type stuff to me, dos anyone know if there’s one in the works? If not, is there anything I can do? Thanks in advance!
