Privacy Policy

Rescue Reach — Z-Core Technologies

This Privacy Policy describes how Z-Core Technologies ("we", "us", or "our") collects, uses, and protects your information when you use the Rescue Reach mobile application ("App"). By using the App, you agree to the collection and use of information as described in this policy.

1. Information We Collect

1.1 Information You Provide

  • Name, phone number, and email address during account registration
  • Emergency contact details you manually add to the App
  • Profile information you choose to provide

1.2 Information Collected Automatically

  • Device location (GPS coordinates) — only when an emergency alert is triggered or when you explicitly grant permission
  • Device type, operating system version, and unique device identifiers
  • App usage data including feature interactions and session duration
  • Incident and alert history generated within the App

1.3 Third-Party Services

The App may use third-party services including Firebase (Google) for authentication, database, and analytics. These services have their own privacy policies governing data use.

2. How We Use Your Information

  • To provide and operate the core emergency alert functionality of the App
  • To share your location with designated emergency contacts during an active alert
  • To send push notifications relevant to your safety and account activity
  • To improve App performance, fix bugs, and develop new features
  • To comply with legal obligations where applicable

3. Location Data

Rescue Reach requests access to your device's location. Location data is used exclusively to transmit your position to your emergency contacts and designated responders during an active emergency alert. We do not track or store your location in the background without your explicit knowledge and consent.

You may revoke location permissions at any time through your device settings, though this will limit the App's core emergency functionality.

4. Data Sharing

We do not sell, trade, or rent your personal information to third parties. We may share your information only in the following circumstances:

  • With your designated emergency contacts, as is the explicit purpose of the App
  • With service providers who assist in operating the App (e.g. cloud hosting, analytics) under strict confidentiality agreements
  • When required by law, court order, or governmental authority
  • To protect the safety, rights, or property of Z-Core Technologies or its users

5. Data Security

We implement industry-standard security measures to protect your data against unauthorised access, alteration, disclosure, or destruction. Data is transmitted using encrypted connections (HTTPS/TLS). However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

6. Data Retention

We retain your personal data for as long as your account is active or as needed to provide the App's services. You may request deletion of your account and associated data at any time by contacting us. Incident history may be retained for a limited period for safety and legal compliance purposes.

7. Children's Privacy

Rescue Reach is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that a child under 13 has provided personal information, we will delete it promptly.

8. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, or delete your personal data. To exercise any of these rights, please contact us at the details below.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected with an updated date at the top of this page. Continued use of the App after changes constitutes acceptance of the updated policy.
