There are various ways you can save videos from Tik-Tok (both yours and other users’) in case they accidentally get deleted. When you open a Tik-Tok video, you will notice a share button on the right bottom corner. Once you click on it, you will have the option to select “Save video”. Make sure you wait a couple of seconds and then the video will be automatically saved in your phone. Just to be extra safe, you can follow that up with a phone backup so that your videos can be recovered in case something happens to your phone.
