FlexafeLite app for iPhone and iPad

Flexafe is a universal app representing an ideal tool for storing useful information in the same secure container. It allows users to securely store different types of items, from Internet or bank account details to insurance policy details, from restaurants opening times to birthday reminders, to-do lists or even wine lists, with the ability to interface seamlessly with the on-board Calendar app, in order to easily link dates to event and/or alarms (for expiry dates in passports or birthday reminders, for example).

FlexafeLite ships with several default templates, but users can easily customize the structure of each individual record. A record item is made up of fields such as usernames, passwords, URLs (web addresses), emails, dates, times, images, and even to-do items or noise levels. Record fields can be easily added, repositioned, removed, and named to suit different needs.

When the user modifies an existing record, or creates a new one from scratch, FlexafeLite transparently defines a new template, or updates an existing one. This way users do not need to worry about template creation or management, but can concentrate on using the application to store information, no matter how this is structured.

FlexafeLite has lots of icons that users can associate with specific items. Item thumbnails can also be derived from images or web screenshots for URL addresses stored inside a record (i.e. an item recording an Internet account can be listed with a thumbnail displaying the home page of that service).

Main features

- flexibility of the individual item structure, easily configurable by users
- ability to group items into categories
- multiple safes, each with its secure individual password (so that you can define separate business, personal, or leisure safes) saved using SHA-2 hashing algorithm
- individual encryption of sensitive data types (usernames, passwords, numbers, phone numbers, email addresses, images) with AES-256 encryption
- fully-featured random password generator
- noise level meter, to store measured sound levels (in decibels), such as when recording the noise level in a restaurant, or a house
- simple automatic template creation and management
- dates stored within record items can generate Calendar events/alarms, accessible from the default Calendar app that ships with the device
- items can have thumbnails, either provided by FlexafeLite, or easily taken from images within records or web screenshots
- thumbnails are stored encrypted for extra protection (in case they are derived from sensitive-data pictures)
- sensitive data is stored encrypted using AES with a 256-bit key
- syncronization/backup using an existing Dropbox account
- use of the latest Dropbox API ensures FlexafeLite has no access to Dropbox login details
- ability to search through items by filtering records by item name
- ability to copy item fields to the clipboard
- built as a universal app means you can use it on iPhones, iPads or iPod touch devices
- FlexafeLite is limited to a maximum of 8 items (can be unlocked with an in-app purchase).

Security

Each safe within the application is individually protected by a user-defined password. In addition, some item fields (such as usernames, passwords, numbers, phone numbers, email addresses, images) are stored encrypted within the filesystem.

FlexafeLite uses Apples Core Data framework to store and manage data, and the protected item fields are individually encrypted within each safe; they are decrypted only when the user requests their display.

Safes synchronization or backup

FlexafeLite allows users to backup their safes using an existing Dropbox account. This way it is possible for two or more devices to synchronize data between them. A single device can securely backup its data without the need for a matching desktop application.

The encryption key is never transmitted with the synchronized data.
