3. Data Storage & Security

Your data is stored on secure cloud infrastructure. Account and application data are stored in MongoDB Atlas. Application services are hosted on Hetzner servers in the European Union. All communication between the app and our servers uses encryption (HTTPS/TLS). Passwords are hashed using bcrypt and are never stored in plain text.

Live audio and video during calls are routed through LiveKit for real-time communication. Speech submitted to the AI coach is processed to generate feedback; we do not use your voice for advertising profiling.

4. Third-Party Services

4Talk uses the following third-party services:

Service	Purpose
Google Sign-In	Optional account authentication
Apple Sign-In	Optional account authentication (iOS)
LiveKit	Real-time audio and video during talk rooms
MongoDB Atlas	Cloud database storage
Hetzner	Application server hosting (EU)
Expo / EAS	App builds, updates, and infrastructure

Each of these services has its own privacy policy. We recommend reviewing them separately.

5. In-App Purchases & Subscriptions

4Talk may offer optional premium features and AI coaching token packages. Payments are processed by Google Play or the Apple App Store (and may be managed through RevenueCat). We do not store or process your payment card information.

You can manage or cancel subscriptions at any time through your Google Play or Apple ID account settings.

6. Data Retention

We retain your data for as long as your account is active. Coaching session history shown in the app during a call is temporary and tied to your active session unless otherwise stored in your account settings.

You may delete your account and associated data in the app (Profile → Delete account) or by contacting us at the email below. Data will be deleted within 30 days of a verified request, except where retention is required by law.

7. Children's Privacy

4Talk is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us so we can delete it.

8. Your Rights

Depending on your location, you may have the right to:

Access your personal data
Correct inaccurate data
Delete your account and associated data
Withdraw consent where processing is based on consent
