When you delete a project, it may be removed from the device on which you deleted it, but whether it's removed from the cloud depends on how PicsArt handles cloud storage. In some cases, it might still be available in your PicsArt cloud storage (if you're using a cloud-based feature) even after deleting it from a device. Be sure to check PicsArt's documentation or settings for specific details on how they handle cloud storage and deleted projects.
