Google Play Publishing status: Rejected

Our app was not accepted by Google Play with reason "APK HAS A PROMINENT DISCLOSURE BUT THE DISCLOSURE IS NOT ADEQUATE. Your app is uploading users' Primary Account information without an adequate disclosure."
We are investigating all potential sources of the problem. In activating the license, the Radaee SDK uses a fixed email address "[email protected]." 
Has this been a problem for your other customers submitting to Google Play?

Dear User:
developers that paid for licese of Radaee SDK shall not using mail "This email address is being protected from spambots. You need JavaScript enabled to view it.".
did you pay for license?
and seems it is not a technology reason.

May you open a ticket here www.radaeepdf.com/support and address it to sales?
Let us know your license details: orger reference number and email address would be enough.

Thanks for your responses. I opened a support ticket as requested.
