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.

Installed it, set a password, all seemed good. Then I got one of those ads were you play a game for a short time. Thing is, it NEVER stopped. There was no close button, not even after a minute and when i tried to force close the app, it OPENED ITSELF right back up with the unskippable ad. Only unistalling the app solved this (which was also a pain because it opened again after 1 sec), it literally made the whole phone unusable. I highly discourage you from installing it and hope it gets removed.

Dear Technical Team, I hope this review finds you well. I am writing to bring to your attention a security vulnerability that I have discovered in your app. Upon using the app, I noticed that when attempting to close my opened apps, there is an icon labeled "active in background" that allows me to stop your app and access other apps without requiring a password. This flaw poses a security risk as it enables unauthorized access to the app without proper authentication.

Awesome app! It's definitely free and easy to use (despite the premium version)! Definitely recommend it. Though, I only wish to have more fake app icons OR be able to upload one and change the name, as well as more natural fake error messages (an error message that looks like a standard error message depending on phone model)
