Please people, wake up and smell the roses. The only thing SecureNotepad has is a password to protect your notes from others.
There is no mention in either SecureNotepad ’s description or or developer’s site on how the notes are secured.
Unless SecureNotepad uses ASE of a minimum of 128bits, preferably 256 bits, encryption and/or other technologies to keep your password and notes safe, anyone with a bit of know how can open and view them.
To say that something os secure but not specify how it is secured, is like a doctor telling you that she needs to give you a shot but not tell you why and for what. It would be nothing more or less than blind trust. Can you trust someone that much? Not me!
Unless the security type and level is specified and tested, this and any other app is completely useless.
Similarly, even if SecureNotepad had the strongest security possible, people using passwords that are considered strong, defeats the whole purpose. Sadly, that is exactly what people do the bast majority of the time.
