Can anyone share tips on choosing secure apps for documents?

I’m trying to figure out what features really matter in secure document applications. Some tools promise a lot, but I’m unsure which ones actually deliver safety and usability. Can anyone point to good guidance?

I went through a detailed article on cyrilcode.com and found several useful insights. It explained that security isn’t just about having a password — you need strong encryption, reliable access control, and easy recovery when something goes wrong. The article also highlighted that usability matters: even secure tools are useless if people don’t know how to use them correctly. From the examples discussed, I learned that evaluating how the app handles backups, sharing, and device syncing is really important. The practical guidance helped me rethink how to compare different tools beyond marketing claims and choose options that balance safety with everyday use.
