What is an Android accessibility service?

An accessibility service is an Android app component that runs in the background, watches what happens on screen and can act on apps for the user. It is built for assistive tools such as screen readers.

Android’s developer documentation says these services “inspect screen content and interact with apps on the user’s behalf”. Examples include screen readers, Switch Access and voice control. [1] You turn a service on in Settings › Accessibility, and Android shows a warning about what the app will be able to do.

Why it matters on Android

Because an accessibility service can be allowed to read the screen and tap for you, it is one of the most powerful kinds of access an app can get. Many legitimate apps use it, including assistive tools, some password managers and some automation apps.

The same power can be misused. A monitoring app with accessibility access may be able to see messages and what you type. An app you do not recognise in the accessibility list is worth a closer look. On its own, that does not prove anything is wrong.

How Applore uses it

Applore uses it in two ways:

• App Lock (optional). If you turn on Applore’s accessibility service, App Lock receives only window-change events. It uses only the name of the app that comes to the front, so the lock screen appears straight away. Applore’s service is set up without access to window content, so it does not read what is on screen or what you type. It is optional: without it, App Lock uses usage access.
• A signal in the stalkerware check. Needs your review treats accessibility access as one warning sign. A sideloaded app that hides its icon and has accessibility access is flagged at a higher level.

The guide on which apps have accessibility access shows how to review the list, and why Applore asks for each permission covers the rest.
