Secure Notes App Concept (Android)

I'm looking for a rough, prototype app.

This app allows the user to save notes on his/her phone in a secure & encrypted form.

the notes are kept organized as Folders and Tabs (within Folders).

user can create multiple Folders. For each Folder, user can add multiple Tabs. Then user can add multiple Notes to a tab.

You will deliver working source code for latest major version of Android studio

App should compile in Android studio and work in emulator, minimum Android version 4.4

Security aspect:

add notes, tabs and folders must be saved on the phone in encrypted form, so they cannot be read by accessing the phone storage from outside the app. The type and method of encryption used must be explained in details, along with how it can be changed.

Screens needed (see attached [login to view URL] wireframe)

1. Home screen

on this screen user can see list of Folders saved on her phone. (simple list view with name of Folder and number of Tabs inside)

tapping on a Folder item creates a New Folder and New Tab and takes her to Edit Folder screen

There is a + Action button to create new Folder that then also lands on Edit Folder screen

2. Edit Folder screen

shows Tabs in the current folder horizontally across the top, First tab is active on landing on this screen.

user can change the Folder name

screen displays the notes in the First Tab

user can click on Tabs which are displayed horizontally across the top to switch to another Tab

+ Action to create a new note in current Tab

Add New Tab option (creates a tab and stays on same screen but makes this Tab active and switches to displaying the notes in this Tab)

Remove Tab option (destroys any notes inside, confirmation message should be displayed)
