To log out of your app, you navigate to the 'Profile Icon' which is the circle at the bottom right of your screen with the person inside of it.
Once in this section you tap on 'Settings' and then on the orange box at the top right, with a grey arrow pointing out of it towards the right. You will be asked if you want to 'Log Out?' at this point and you can select to do so.
Please watch the video below for further guidance, or if you have any further questions please raise a ticket here to contact a WordGo customer support agent.
