Google Drive doesn’t really delete your files even after you delete them
Yesterday my dad accidentally deleted some important files from his Google Drive account, even from the bin. So we gave it try to contact the Google support to restore these files having no hope to succeed. Yet it worked, we restored them, which was really great, and he was happy about it.
Although what came to my mind is the issue of privacy. It seems we don’t really own the data once we upload it to the Google servers. So obviously you are not able to get rid of your files without leaving a trace. It means that Google or basically any 3rd party such as government officials or police can nevertheless restore and access the files you thought you had deleted as they are still stored on the Google servers.
