Service for creating screenshots with protection from prying eyes?

Question

Information Security

Hello, friends!
Recently decided to switch from Lightshot to some more secure alternative.
I spent a couple of hours searching and found absolutely no options with the functions I was interested in, so I decided to resort to your help.
What options would you like to see?
-Storage of the screenshot in encrypted cloud storage.
-Online access by password
-Self-deletion
What can you advise?
