TikTok used to tell you who has viewed your profile, but in recent updates they’ve removed the feature, making it unavailable for all users. There is no longer a way for you to see who is visiting your profile.
Previously, all you had to do was open your TikTok app, tap the notification icon, then tap “viewed your profile.” From there, you’d be taken to a list of all of the accounts that had seen on your profile, either by searching for you specifically, seeing your videos organically on their For Your Page, or tapping on your username on a comment, caption, or tag in another video. It’s possible you can still do this if you have an older version of the app.
Since the developers have removed this feature, you can now view anyone’s profile as many times as you’d like without them knowing. Feel free to browse users as much as you’d like, but remember not to accidentally “like” anything from too far back if you don’t want them knowing you’ve viewed their profile.
If you don’t want random people to be able to find your account for whatever reason, you can put your TikTok account in private mode. That way, you’ll have to allow them to follow you before they can visit your profile and watch your content.
