About Pin Keeper Add Supported

This application's main feature is its simplicity it doesn't try to do any funky stuff with your valuable data.

Simple is safe as there are less chances of data being miss-handled and made unintentionally visible. You always have control of your data and you will always hold the keys to your lock!

If adds and in app purchases bother you, get the paid version; for a few cents it safeguards your privacy, doesn't ask for any permissions and is smaller in size but has more features. Either way all your data is kept encrypted using AES256 with all of its cryptographic attributes (Random salt, SHA IV high number of cycles etc,) and kept on your phone's application private storage.

Pin Keeper uses both a PIN and an encryption phrase. The encryption phrase is never stored on your phone and must to be entered every time therefore making it very hard for anyone to ever de-crypt your data if you lose your phone. The PIN lets you into the app and is stored encrypted in the app but the data is encrypted using the phrase you registered and is not stored in the app in any form or way making brute force attacks very hard (subject to you having chosen a good phrase)

NOTE:

1. I/we cannot recover your password or key phrase if you lose them. The only way to restart is to uninstall and reinstall the application. Deleting the app also deletes all of your PIN data. This means that a Google initiated remote phone wipe should in theory also remove all your pin data. Keep a copy of you pins in a safe.

2. If your phone is rooted then anything stored on it will be less safe as private storage is accessible by any other application granted root privileges. Additionally such root empowered applications could implement ways to block read this application's memory thus potentially capturing master pin and encryption keys.

3. Why is this app so bland and featureless? Because I built it to store my own passwords as I don't trust anyone out there. I don't need it for anything else so there is nothing fancy in it.
