TikTok does not currently allow users to see who has saved their videos. However, there are several third-party apps and websites that claim to offer this functionality. It is important to note that these apps and websites are not affiliated with TikTok and may not be reliable or safe to use.
If you are concerned about who has saved your TikTok videos, you can take steps to protect your privacy. You can set your account to private, which will prevent anyone from saving your videos without your permission. You can also disable the “Allow downloads” option in your account settings, which will prevent anyone from downloading your videos.
