iOS' App Store has a good breakdown of what's collected too. It's sort of like a nutritional label of what's collected. It's why I won't install this app. It's a data grab by TikTok to turn personal info into gold ingots.

One thing I do though, since missing out on TikTok bothers me, is to watch YouTube clips of TikTok videos which have been downloaded and shared on YT. Not that YT is better in terms on privacy, but it's better than having a Chinese malware app on your phone.
