Later versions of Android require the allowing of needed permissions.
When you first start the app, you will get 2 notices to allow permissions.

Storage Permission

  1. Notice:  Storage Permission Needed
    This explains why we need this permission
  2. Notice:  Allow Complok Email to access…….
    Tap:  Allow

Contacts Permission

  1. Notice:  Contacts Permission Needed
    This explains why we need this permission
  2. Notice:  Allow Complok Email to access…….
    Tap:  Allow

Manual Set Permissions

You can also set permissions manually, as described here and in the image below.

  1. Settings icon
  2. Apps or App Manager or Application Manager (depending on version)
  3. Find and tap on Complok Email
  4. Scroll down to Permissions
  5. Set both Contacts and Storage to ON
  6. Return to Email app


This process is basically the same as the PC version, just different windows and screens.

The most important up front decision is in screen 2.  First setup OR subsequent setup on another device.

Important Choice:

1.  First Setup – First Device.  This is the absolute first time installing Complok email on any device, PC or Mobile
2.  Second + Setup.  You have setup Complok Email before on another device and already created your Master Password and PPF file.

Refer to this image for the steps that follow.

The above screens:

Screen 1:  Password Info

Contains info on the password you will create in the next screens.  When you have properly set permissions, the Next button will enable.

Screen 2: User Type

You MUST choose the correct option here.  This is most important. Slow down, do it right.
If you have setup Complok Email on any other device (PC or Mobile), choose SECOND + COMPLOK SETUP

Based on your User Type you will next go to either screen 3a or screen 3c.

Screen 3a: Passphrase Creation (FIRST COMPLOK SETUP)

Enter any phrase you want, just has to be at least 10 characters long (no spaces)

Screen 3b: Password Passport File Creation (FIRST COMPLOK SETUP)

Click CreatePPF to create this file, which you will use for all future Complok Email setups (PC or mobile).
It is created in folder: Documents > Complok Email

Screen 3c: Existing User Input (SECOND + DEVICE SETUP)

Three items required on this screen:

  1. Enter the previously thought up and remembered, Passphrase.
  2. Transfer the previously created (on another device) Password Passport file to a folder on this device.
    a. Email it, using your existing, regular email account on this device, then navigate to where it has been downloaded/saved.
    b. Attach your device, via USB to your PC and drag it over to this device.
    A good folder for this is: Documents\Complok Email\
  3. Enter an email account from your other device.  This is how we check that the above 2 items have been entered correctly

Tap Validate and if all checks out, the Next button will enable and you will be taken to Screen 5 as seen above.

Screen 4:  Setup Summary (Both user types)

Congratulations.  Your super password for the Private Key protection is created.
Next up is your ACCOUNT. Read the info, then click the button ‘Account’

Screen 5:  Create Account

Four items to add here:

  1. Tap the Provider List and choose your provider
  2. Enter your full email address (Example:
  3. Enter your Display Name for this account
  4. Enter the account password

Tap Validate and we confirm that your credentials are correct before proceeding to the next screen.  Tap Next

Screen 6:  Finish Account

Your account credentials were valid, so now we can create your encryption keys, encrypt the private key with your very large password, and get everything setup on your device and the cloud.  Press Create.


In order to provide an extremely secure, yet seamless experience for users, we utilize a Bridging Cloud Server, and guess what, clouds cost.  You can use Complok Email as is and be just fine, except you cannot encrypt your emails or use messenger beyond the initial free trial period.  To provision encryption:
