Is TikTok safe for phone privacy?

Some friends told me TikTok collects too much data, while others say it’s just like any other social app. I’m not sure what to believe. Has anyone here faced any security or privacy problems after installing TikTok? For example, unusual phone activity, battery drain, or strange permissions?

I was hoping to get some feedback on this because I’ve also noticed people mentioning TikTok 18 along with the regular TikTok app. From what I understand, TikTok 18 isn’t an official version — it’s more of a modified app that isn’t available on the Play Store. That makes me wonder if the privacy and security risks are even higher there, since unofficial apps don’t always go through the same checks as the main TikTok app.

So I’m curious if anyone here has actually seen real issues, like phone performance slowing down, strange permissions being requested, or even malware risks, either from the main TikTok app or from TikTok 18?
