Does the site where you download videos from Tik Tok make copies? Buddy, this is a problem with many sites, and even after many complaints about the sites, they don't stop saving videos. But I found a site and it definitely doesn't make copies of downloaded videos https://savetiktok.me . But he has a lot of advantages. It doesn't require registration or any kind of payment for services. And I'm sure you will use this site for many years, I hope it helped.
