TikTok
What you grant
What is kept
Your display name and counts, encrypted access tokens, and the reports Ostrel writes from your video stats. For a scheduled post: the video file until it is published, then deleted; the caption and settings you chose; and the post ID TikTok returns.
What never happens
Ostrel never downloads your videos from TikTok. What it sends to an AI model from TikTok is text (captions, dates, lengths and counts) and each post's cover image, the still TikTok's own API provides, so the AI can judge the cover. Ostrel fetches the cover fresh each time and keeps no copy. If you want Ostrel to watch a TikTok, it uses your own copy instead: the same video on your YouTube Shorts or Instagram Reels, or the original file on your computer. Before you post, Ostrel shows your nickname, lets you pick the privacy level with no default chosen for you, and leaves comments, duets and stitches off until you turn them on. Until TikTok approves Ostrel for public posting, TikTok itself makes every post from Ostrel visible only to you, whichever level you pick. Your post is not lost: you can change who sees it in the TikTok app.
