Text to Hyperlink

Converting entered text to a clickable link before sending, is a great convenience to your recipient.  On receipt, the recipient can then just tap on the link to open in a browser or share.

To perform this function, follow these rules:

1. The link text must be the only text entered and in proper URL form
2. Appropriate text formats are:

3. After the link text is entered, tap the Link icon in the top toolbar
4. Formatting will added to the text and it will turn blue

After you have performed the conversion, you can hit the enter key one or more times, and enter more message text.  This additional text will not be in the link but will also be colored blue, just letting you know you are sending a clickable link in the message.

2. Tap CHOOSE SORT FOLDER and select desired folder

To remove a auto-sort, tap the REMOVE ADDRESS button, find the address and tap it

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 in the EXCLUDE FULL ADDRESS area.


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:

How we do this

1. Initially choose BLOCK and REMEMBER SELECTION – NO
2. Check that email opens OK and what you need is accessible
3. If OK, then reopen email, and this time BLOCK and choose REMEMBER SELECTION – YES



Hi Security Mode

Out of the box, all emails between Complok users are fully End-to-End encrypted, if the ENCRYPT MESSAGE box is checked.  At this initial level, 3 separate encryption keys are generated, unique to each email, which protect the email contents.

Note:  If you select ENCRYPT MESSAGE and send to a non-Complok user, they will receive unreadable gobbledygook.

Max Security Mode

Add a SHARED SECRET to the encryption keys
Click the 3 dots (lower-left), and select SHARED SECRET
The SHARED SECRET window opens

Here, both parties agree on a ‘Shared Secret’ word/phrase.  The only difficulty is how to share something like this in a secured manner.
Proper options for this are:

1. In person
2. By regular mail in a sealed envelope
3. By confirmed encrypted text or voice mail messaging

Each party, then enters the secret in their own app as in this following example:

Bob’s email:
Sally’s email:
Shared Secret:  MountainTop789

Bob, in his shared secret page, enters Sally’s address ( and the secret (MountainTop789)
Sally, in her shared secret page, enters Bob’s address ( and the secret (MountainTop789)

Multiple Accounts

If either party has multiple accounts, then the SHARED SECRET must be entered for each account. 
If in the above example, Bob has 3 email accounts (,,  Sally then would enter the shared secret MountainTop789, 3 times, once for each of Bob’s email addresses.

Desktop App

If you also are using our Windows 10 email client, then you must use the same shared secret word for that recipient’s email address.  Our desktop app synchronizes perfectly with the mobile apps.


You can and should use different shared secret words for each contact you have.  Complok does NOT store or have any knowledge of your secrets.  It is entirely up to you to write them down or remember them in a way you choose.


To open the SETTINGS window, go to: Options > Settings

Limit Seen Emails

Complok will load all emails in any given folder, which is unlike other email clients which force you to wade thru screen after screen to get to older stuff.  Here, you can set a limit number to show for faster loading.
