Custom profiles Create your own profiles for travel, work, weekends or any routine. Give each profile its own selection of actions and switch when you need a different menu. EASY FROM THE FIRST PRESS The built-in guide walks you through Settings, Action Button and Shortcut selection. Choose Open Launcher for your personal menu, or create a shortcut with Open a Sidekey Tool to open a supported tool directly. You can also set up Siri, Back Tap, a Home Screen shortcut or a Shortcuts widget. Interactive 3D illustrations help you explore the button and understand setup. ABOUT PRIVATE CAMERA You start each capture with visible camera controls. The private library locks when the app enters the background. Private captures are excluded from device backups. Export anything you want to keep before deleting the app or allowing SideKey+ access to end. Subscription expiry does not automatically delete saved captures, but access to the library requires an active subscription. The physical Action Button requires a compatible iPhone and setup in Settings. Some tools require permissions, and some actions require shortcuts you create in Apple Shortcuts. Your iPhone may need to be unlocked.
