I've checked the official website of Safeplicity and here's what is says regarding trial limitations:
- Can I still access my data after the trial expired?
- Yes, you can! However, there will be a delay every time you try to access your files.
As you can see you can still get access to the files, only that you'll have to wait a little longer. Simply access your files and the software will appear with a slight delay. During that time, unlock the folders completely and uninstall it.
