It's simple to update your Embark privacy settings and remove that dreaded Padlock icon forever. 

Here's how: 

Log into your Embark account.

Choose SETTINGS (upper right hand corner). 
Scroll down a bit and look for DEFAULT PRIVACY SETTINGS.
See how there is a column for PUBLIC and NOT SHARED?
Simply change the buttons to PUBLIC for everything, and be SURE that the box is checked next to “Update ALL Dogs with these Settings”. 

Click on the blue button that says SAVE DEFAULT PRIVACY SETTINGS.

That's it!
