Introducing Sec-Notes, Most secure android note app

Sec Note is a password protected free note taking application for android. It helps keep all your
personal data secure and safe on your android phone. You can create simple notes,
spreadsheets(Excel type) and checklists. It is the only app in play store offering multiple security
options like password protection, pattern lock and pin lock.

All notes are stored internally using NSA grade AES128 encryption. That means even if a thief gets
hold of your phone, he won't be able to read any of your notes even if he manages to root it.
There are multiple backup options as well - SD card, Google drive and Dropbox. Just enable
backups and any changes you make to your notes will be automatically backed up. Backed up notes are
also encrypted and hence are perfectly safe from hackers.

Sec-notes also auto locks itself once you stop using it. Say you looked at a note and simply put the phone
in your pocked without locking. SecNotes will automatically lock itself so even if somebody manages to get
hold of your phone in the time being, they will not be able to see any of your notes.

I use this app heavily to write down thoughts, finances, talking points, shopping lists & much more! I can't do without this app!
