Barcode Generator / Reader for Android is a derivative work of ZXing for helping us to generate QR code quickly for sharing to other applications by sending mechanism and also to read barcode by sending mechanism from other applications.

There are so many people asked me why do I need to ask for read_sms and read_contacts permission. The reason behind these permission is data sending in Android which uses URI style pointer to let any applications to register itself as provider. Messages and Contact provide their content as providers to let other applications to read the content.

Anyway, the best way to claim you is to publish the source, it was I thought. If you are do concern the privacy, read the code, compile it yourself and install it yourself. It is released using Apache License 2.0.
