Is there any way to have a totally anonymous Tiktok account that NONE of your contacts/people you live near can see?

I want to start a new Tiktok account but plan on posting really personal content on there. The last time I went on Tiktok, I remember my account got recommended to my phone contacts even though I specifically turned contacts off (this only stopped my contacts from getting recommended to me, it didn't stop ME from getting recommended to THEM). I've also heard of people getting their accounts recommended to people that they crossed paths with or live near because it can track location. Once again, I don't want this as I live with roommates and don't want them getting recommended my account.

I just want a totally anonymous account like Reddit that absolutely no one I know will be recommended. Is this possible at all on Tiktok?
