Phone by NAIL

Phone by NAIL can detect scam calls in real time and hang up the call before you share verification codes or your personal information. It also comes with handy AI features for those who do a lot of phone calls.

Accessibility Service Disclosure:

Phone by NAIL uses the Android AccessibilityService API for one purpose — to support scam detection during active phone calls. When the service is enabled, it helps the app identify potentially fraudulent calls and warn the user.

Phone by NAIL does not use the AccessibilityService API to change device settings without permission or prevent users from disabling or uninstalling the app. The service does not request access to your screen content, keyboard input, or touch interactions.

All processing happens on your device. This app has no INTERNET permission, so your data never leaves your phone. You enable the service yourself in Android settings and can disable it at any time.
