Privacy Policy

Basic approach

The App provides disaster-response guidance, rescue sounds and lights, location checking, emergency calling, and evacuation-place notes. No account is required. The App does not use advertising or behavioral analytics SDKs, and it does not sell personal data.

Information handled on your device

To provide features and retain settings, the App may handle the following information on your device.

• Display language, communication language, low-power setting, and onboarding completion status
• Emergency contact names and phone numbers, and evacuation-place names, descriptions, and intended persons entered by you
• Progress through earthquake and tsunami response flows
• Latitude, longitude, accuracy, and capture time when location is used, including the last obtained location
• Device state needed for display or feature control, such as battery level

Permissions and device features

Permissions are used only for their corresponding features and can be changed at any time in device settings.

• Location: to obtain, display, and copy your current location after your action. Location is not sent to a server operated by the App.
• Camera: to control the rear torch and SOS flashing. The App does not capture, save, or transmit photos or videos.
• Vibration: to provide tactile confirmation of completed actions and SOS activation.
• Phone, contacts, and maps: to open your device dialer, contacts, or map app after your action. The App does not read your contacts list.

External service processing

For stability and abuse prevention, the App uses the following Google Firebase services. Device, OS, and app information, crash details, IP address, and tokens or attestation results needed to verify app integrity may be transmitted to and processed by Google.

• Firebase Crashlytics collects errors, stack traces, and diagnostic information such as device, OS, and app version for troubleshooting and quality improvement.
• Firebase App Check (Play Integrity on Android; App Attest / DeviceCheck on Apple) verifies that requests come from a genuine App and helps protect services from abuse.

Google’s Privacy Policy and the applicable service terms govern Google’s processing and retention of this data.

Purposes and sharing

Information is used only to provide features, apply your settings, resume disaster-response steps, improve safety and stability, and prevent abuse. Except where required by law, we do not sell personal data or disclose it beyond what is necessary for the service providers described above.

Retention, deletion, and security

On-device data remains until you change or delete it, clear the App’s data, or uninstall the App. Permissions can be revoked in device settings. Crashlytics and App Check data follow Google’s settings and retention policies. We use reasonable safeguards, but no method of storage or transmission can be guaranteed completely secure.

Children’s privacy

The App does not provide child-directed advertising or tracking and is not intended to knowingly collect personal data from children. Guardians should manage device permissions and entries where appropriate.

Changes and contact

We may revise this policy when features, services, laws, or store requirements change. Material changes will be announced in the App or on its distribution page. For questions, use the developer contact shown on the App’s store listing.
