Connect TikTok from the Account tab in the app. You'll go through TikTok's own login screen (Artec never sees your TikTok password).
Once connected, Artec reads your video list and per-video stats: views, likes, comments, and shares. Your videos sync right away. After that, new posts are picked up automatically throughout the day (usually within minutes to a few hours for active accounts), and your full video list gets a fresh check weekly. Follower and engagement stats refresh nightly.
Artec has read-only access: it can never post on your behalf.
