This page explains how to set a Passcode (4-digit number).
①Tap the menu button "≡" at the top left, then select Settings.
②Tap the "Passcode" button in app settings.
(If it is orange, it is already on. To set it again, turn it off first.)
③Enter a 4-digit number to set your Passcode.
(For confirmation, enter the same number twice as instructed on the screen.)
④If the "Passcode" button is orange (on), setup is complete.
When you finish using the app, swipe it closed instead of using Log Out. The Passcode entry screen will appear the next time you open the app.
(If you swipe the app closed, you are also logged out automatically.)
How to close (quit) the app differs by device. See the pages below.
