Since all files are stored locally on the device, we can't restore a deleted file.
If you are using an iPhone, iPad or iPod:
When you delete a project, it goes into your Recently Deleted folder. If you change your mind or accidentally delete a project, you have 30 days to get it back. Open the Files app and go to Locations > Recently Deleted. Select the file that you want to keep and tap Recover. After 30 days, your files are removed from Recently Deleted.
If you are using an Android device:
If you use Stop Motion Studio 7 or later and you delete a project, it goes into a Recently Deleted folder. If you change your mind or accidentally delete a project, you have 7 days to get it back. Open the Files app and go to the project folder > Recently Deleted. Move the project, you want to keep, back into the project folder to recover it. After 7 days, your files are removed from Recently Deleted.
