Short reads on how Kept works, from setup to safety.
If your phone is visible to other people (a shared house, family, a partner who isn't part of your dynamic, a workplace), Kept has a few optional settings that make it less obvious what the app is.
All of these live under Account -> Security (the device-privacy ones) or Account -> Settings (the icon), and every one of them is off by default and per-device. Turning one on on your phone doesn't turn it on if you sign in on a tablet too.
Blocks the screenshot the OS takes of the app when you switch away from it, so someone flicking through your open apps sees a blank tile instead of whatever screen you were on. Since the app switcher is the most common way an app gets seen by accident, this is a good first setting to turn on. The tradeoff: it also blocks your own screenshots and screen recording of the app while it's active.
Adds a fingerprint, face, or device-PIN check every time you open the app or come back to it after switching away. This adds a small daily cost in exchange for protection against someone picking up an unlocked phone and opening the app directly. Worth it if that's a realistic scenario for you, unnecessary if it isn't.
Already on by default, so there is nothing to turn on here, but worth knowing about. Push notifications show generic text ("You have an update") instead of naming a task, a Dom, or any other detail, so a lock-screen preview doesn't give anything away even with both of the settings above turned off.
Kept ships light and dark icon variants, plus a small set of generic alternates, and you can pin one permanently from Settings -> App icon rather than having it follow your theme. Once you pick one explicitly, later theme changes stop affecting it. One limitation: iOS can't change the app's name shown under the icon, only the icon image itself, so whatever name is on your home screen now is what stays there.
