Accessibility Service disclosure
AppLock's Website Blocker feature uses Android's Accessibility Service to block the websites you choose. When you turn on Website Blocker and grant the permission, the service reads only the web address (URL) shown in your browser's address bar in supported browsers (Google Chrome and Samsung Internet) to detect when you open a site or category you've chosen to block, and then shows a block screen instead of the page.
• It is used only for the Website Blocker feature, and only after you enable it and grant the permission.
• It reads only the address bar (the site's web address). It does not read page content, capture what you type, read your passwords, or record your screen.
• Android does not offer another way for an app to detect the page a browser is showing, so this permission is required for the feature to work.
• You can turn Website Blocker off at any time in the app, or revoke the permission at any time in Android Settings > Accessibility, which stops the service completely.
