DataBack is the poorest application on the internet. They just make fool of people just in a legal way.
Actually the older version of this application is much better but then newer one. They just make fool by sending some messagaes to attract more and more people.
When I install the newer version of this application then I realise that they just make fool of new users. In starting they give you benifits but after four to five times using these offers they keeps on sending offers but you will not receive any prize fot these offeres.
