I have had instances where previously "archived" photos reappeared among my regular photos on Android devices. It's a faith-shattering moment. Let's face it, most of us have some amount of photos or screenshots we don't want unexpectedly popping up when other people may be able to see them. In my case, it may have been user error resulting from the confusing interplay between my camera app, the default Samsung photo album, and Google Photos. I guess. Ultimately, I removed permissions for accessing photos from every app except for Google Photos to reduce the chance for confusion.

Does anyone have a simple, cross-platform solution for storing (yet easily accessing) private photos and videos? Or do most people just resort to living dangerously?
