I made an app which enable us to download tiktok video by using api to extract tiktok video url and ffmpeg library. However, app store rejected it because of Guideline 5.2.3 - Legal - Intellectual Property.
"Your app allows users to save or download music, video, or other media content without authorization from the relevant third-party sources."
In app store, a lot of video downloaders are listed such as tik saver, tiksave, video saver and so on. How do they release their video downloader? Can I get permission from appstore, if I do not specify the third party video's name, such as "TikTok"?
