Two factors that may be causing this:

 

  1. Your application keeps a constant connection to the 3NCRYPT3D servers during the login session, so that you can access your Messages, Contacts and other information. Depending on the quality of your internet connection and your equipment’s hardware, you may experience some slower accesses. 
  2. All the encryption and decryption processes of your messages and files occurs on your device. Thus, when there operations are being processed is a possibility that the application may become a little slow.

 

We appreciate your patience, since this is the downside of security.
