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 great file is created, then combined in special ways with your Passphrase, to come up with your 100+ character master password which protects your encryption keys.  All this is done in the steps seen below in the next section.

Important:  Once created, the same Passphrase and Password Passport File must be used on ALL subsequent Complok Email App setups on ALL future devices.

In this initial setup you will need to either create this file or import it from another device, if this is your second+ setup.

First Device – First Ever Setup

After you have come up with your Passphrase (3a), the next screen (3b) will have your Create Password Passport File.  When you press, Create, this file is created and stored in the Email App file library, in the Downloads folder.  This folder can then be accessed by Complok Email, where you can send this file, as an email attachment, to a subsequent device for future setup there.  In this option, you would be using the default device’s email program to perform this function.  Another option for you to share this file for use on another device setup, is to share it to the cloud, then access the cloud on your next device.

Share Summary

1. Send file as email attachment and receive it on your other device for email setup
2. Share file to your cloud, then access the cloud and file on your other device for email setup

Second+ Device – Have setup email app on another device previously

In this situation, you use your previously created Passphrase and Password Passport File.  In screen 3c, below, click the Browse PPF button, utilize the file picker utility and find the file, PasswordPassport.txt.  See just above, the Share Summary of how to get it onto your device.

Seen below are the steps, Android and iOS, using the Google Drive to easily browse and attach your PasswordPassport.txt file.


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 Complok’s folder: Downloads

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/MAC and drag it over to this device.
  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.

Important Note:  Many email providers require additional settings in your browser based email account in order to allow a 3rd party email client (which Complok is).  You can click here to learn more.


In Settings and Options, select Manage Accounts, to bring up the Manage Accounts window.  Here you can Edit, Set Primary, Delete.


In edit, you can change the display name and the port values.  Your account password is required to allow the edit


If you have multiple accounts, you can set the primary account to appear on app start



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:

  1. Tap Settings (3 dots)
  2. Select:  Key File Share
  3. Enter your email address and tap Create

Manually add full email address or the domain (part of email address after the @) for that email.  All future emails will then be automatically deleted on arrival to your account.  If later you wish to remove an address or domain, tap the appropriate Remove button, find the item to delete, and select it.

Example for what a domain entry is:

Original address:
Domain entry for this screen:

Excluded Domains

Add domains here that you do not want accidentally added during a mass delete operation, perhaps in the junk folder.
We have prepopulated this file with our 9 provisioned provider domains.

Email Auto-Sort

Manually add full email address or the domain (part of email address after the @) for that email.  Then tap the Choose Target Folder button to select the folder to sort to.  All future emails will then be automatically sorted to that target folder.  If later you wish to remove an address or domain, tap the appropriate Remove button, find the item to delete, and select it.

Example for what a domain entry is:

Original address:
Domain entry for this screen:

Phish Manage

In addition to the built in, phish scan rhetoric words and sentences, you can add additional words or short word sequences to be scanned on all read emails.

If you receive regular emails from known senders that may always have phishing words in them, you can exclude the from future scanning by entering the full email address.


All emails opened for reading are scanned for hidden tracking pixels.  Recall, that these little gems send info about you back to the sender, supposedly in the name of advertising.  If found, a pop-up alert will appear:

In the above, you will most likely be choosing Block.  Perhaps the first time you encounter an email from a reputable sender, you may wish to choose Block and on the next alert, select No. Then check out the email content and if all is good (content normal, other images normal, links work that you want to use), re-open the email, Choose Block, then select Yes.  From now on, all received emails from this sender will have this action applied, automatically.

We would not recommend this 2-step evaluation method on unknown spams.  On those, Choose Block, then select Yes, right off the bat.
