You stay in control of your videos. To remove a reel:
- Open your profile, Reels tab, then the reel in question.
- Open the video's … menu and choose Delete.
The video then disappears from the feed, from Explore and from your profile, and the stored video is cleaned up.
To change a video, the simplest way is to delete the old reel and post a new one. If the reel was linked to a listing, edit the listing in Sell.
Want to delete your whole account? You can do so directly from the app settings; all your content, reels included, is then removed.
