There is no warranty and no party shall be made liable to you for damages. If you lose coins due to this app, no compensation will be given. Use this app solely at your own risk.

For Bulk Wallet we recommended using Google Chrome, it's the fastest.
Requires IE9+, Firefox, Chrome or sufficient JavaScript support.
Mobile Safari only works with iPhone4 or newer devices. Older devices timeout while executing JavaScript.
DO NOT use Opera Mini it renders JavaScript output server side, therefore they might record the private key you generated.
BIP38 most likely will not work on mobile devices due to hardware limitations.

The application may have unfound bugs and problems. To leave feedback: 
1. PM me
