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.

★★★★★Thakur Mandal· Aug 20, 2026
Nice lock app only problem this app on nah in karen to lock not applied
★★★★★Jozet James· Aug 20, 2026
I love this app, I'm so happy it's free. I don't want, nosie people in my business, even if they are related to me. Thank you for making this app. I can't help it. Now when I leave my phone, I know no one can open anything on my phone. I can't wait for my first victim, they going to get their feelings hurt, not being to check my phone out and to see what I've been up to. And again thank you so much for this app and also making it free. The ads don't bother me, because It's Free.
★★★★☆Cameron Feetham· Aug 29, 2026
The app works and its great the only problem is that it promotes its no adds thing through every app u unlock its easily avoidable, but it charges ur 39,99 a year although its probably worth it because the pop-ups are annoying but maybe make it a monthly payment aswell or get rid of the ads because im just trying to protect my apps not look at adverts when im trying to get in
★☆☆☆☆Prithvi Obhan· Sep 3, 2026
Too many ads, you won't be able to get in the app without seeing the ad, and it becomes frustrating when you are in a hurry and also embarrassing if you give your phone to someone else, not recommended, they need to figure another way to show ads without disrupting the user
★☆☆☆☆Flames Clyver Umali· Aug 29, 2026
It keeps making me do the password even to remove the thing
★☆☆☆☆Humaira Nadeem· Aug 15, 2026
Broo I feel I have noo privacy I go to my WhatsApp, and it shows the pin that I do not even want (don't recommend)
★★☆☆☆Landon Flowers· Aug 29, 2026
It would be nice if you fixed the like ten thousand freaking bugs like it won't let me uninstall other apps without using my password and I don't have any lock set for anything like that
