Hearing Book

Accessibility service (optional): Hearing Book can use Android's Accessibility API,
with your explicit permission, to detect presses of your device's physical Volume
Up/Down buttons — even when the screen is locked or the app is in the background —
so you can start or stop hearing amplification and recording without unlocking your
phone. This is used only to detect volume key presses; it does not read your screen,
other apps, or any personal data, and it is never used to record phone calls or
change any device setting. Before you can enable it, the app shows an in-app screen
explaining what it does and asks you to confirm. You can turn it off anytime in
your device's Accessibility settings.
