If you’re a fan of the popular app TikTok, there’s a good chance you’re using it on your iPhone. But if you want to stop people from watching your videos, there are a few steps you can take. First, open up the app and sign in. Then, go to the “Settings” section and select “Privacy.” Under “Privacy,” select “Block all content.” Now, tap on the blue checkmark next to each video you want to block. You’ll then be able to watch your videos without anyone else seeing them.
