PastyShorts is a private desktop tool used only by the owner of the TikTok account @pastyclipsshort and the YouTube channel Pasty Shorts to publish his own edited short gaming and comedy clips.
The owner signs in with TikTok (Login Kit) and Google, selects a finished vertical video, writes a caption, chooses the privacy level and publishes it to his own account via the TikTok Content Posting API and the YouTube Data API.
It is not a public service: no other users sign up, and no data from other people is collected.
