Prepare a way to reach trusted contacts from your Android phone. Mango Guardian combines a manual SOS button with an optional volume-button shortcut.

Add the protected person's name and emergency contacts, then complete the guided setup. SOS can sound a siren, blink an available flashlight, attempt a call to the first configured contact, and prepare an SMS containing your last known location when available. If configured and available, WhatsApp can open an alert draft too. You must review messages and press Send; opening a draft does not mean it was delivered.

The app also attempts to capture an emergency photo and a short video. Emergency reports, including contact details, available location and captured media, may be uploaded to Google Firebase. These reports are separate from optional usage analytics. Read the privacy policy before use.

The interface offers English, Hebrew, Spanish, French, Russian, Arabic, German and Italian. Manual SOS remains available after setup without enabling the optional volume-button shortcut.

AccessibilityService disclosure

Mango Guardian offers an optional hardware volume-button SOS trigger. To provide this feature, the app uses Android AccessibilityService to detect hardware Volume Up and Volume Down key events while the app is in the background or the device is locked. Holding both volume buttons together for 2 seconds triggers the configured SOS actions.

The AccessibilityService is used only for this volume-button trigger. Mango Guardian does not read or collect screen content, typed text, contacts, messages, or activity in other apps through AccessibilityService. It does not perform gestures, press controls, change settings, or bypass Android privacy controls. Raw key events are processed on your device and are not saved or shared. An SOS report may record that the volume buttons triggered the emergency and send that fact to Google Firebase with the emergency report. Users must review a prominent in-app disclosure and explicitly agree before Android Accessibility settings are opened, and they can disable the service at any time.

Mango Guardian is not an accessibility tool and does not use the IsAccessibilityTool flag.
