To delete or save a Snap you posted to Snap Map or another public Story…
- Tap ⚙️ in your Profile to open Settings
- Tap 'Spotlight & Snap Map' to view the Snaps 👀
- Tap to save the Snap to Memories
- Or tap 🗑 to delete the Snap
(it will also be deleted from Search and Context Cards)
Keep in mind that Snaps submitted to Snap Map and other Public Stories are public content, and your Snap may still appear outside of Snapchat if it has been shared outside of Snapchat.
