Hello. I was wondering, what's the most private and secure cloud storage option right now.

My use case is, I'm overweight and on the journey of losing weight. I want to keep track of my body and save every kind of information about my body in a safe, secured place. Which includes captured photo of my body, medical reports and everything in between.

I don't need paid plans of 100 GB storage and more. I'm keeping track for 1 year, and I think that'll mostly hold up within 10 GB.
