Privacy Policy for FastX Tunnel
Last Updated: April 12, 2026
This Privacy Policy explains how FastX Tunnel handles information, system permissions, account features, and third-party services when you use the app.
1. Basic Principles
- FastX Tunnel is a VPN / proxy client application used to import node profiles, download subscriptions, connect through Android VPN APIs, and manage connection status.
- We do not sell your personal information.
- We do not intentionally collect the content of your browsing activity, communications, or unrelated files on your device for our own purposes.
2. Information We Process
Information you provide
- Server addresses, ports, protocols, subscription URLs, routing rules, and other configuration data that you manually enter or import.
- Account information you provide when you use email sign-up, email sign-in, or Google sign-in, such as email address, Google account identifier, and display name.
Information generated during use
- Network state information used to determine whether the device can connect, refresh subscriptions, or load remote settings.
- Basic connection and service information such as connection status, subscription update time, service traffic usage, remaining quota, and expiration time.
- If you use our service gateway, the app may sync your service account, subscription URL, and traffic package details.
Information that may be processed by third-party SDKs
- Firebase Authentication for email sign-in, Google sign-in, and identity verification.
- Firebase Remote Config for remote settings such as ad placement and feature switches.
- Firebase Analytics for basic analytics and product improvement.
- Google AdMob for ad delivery and performance measurement, which may involve device identifiers, IP address, and ad interaction data.
- Google ML Kit Barcode Scanning for QR code import.
3. Permissions We Request and Why
android.permission.BIND_VPN_SERVICE
Required to use Android's VPN framework and establish VPN / proxy tunnels.
android.permission.FOREGROUND_SERVICE / android.permission.FOREGROUND_SERVICE_SPECIAL_USE
Required to keep the VPN service running reliably in the foreground.
android.permission.INTERNET
Required to connect to selected servers, download subscriptions, sync remote configuration, sign in, sync service data, and load ads.
android.permission.ACCESS_NETWORK_STATE
Required to detect whether network connectivity is available.
android.permission.CAMERA

4. How We Use Information
- To establish, maintain, and disconnect VPN / proxy connections.
- To import, store, update, and display profiles, subscriptions, and routing rules.
- To support email sign-in, Google sign-in, password reset, and email verification.
- To bind your app identity to a service gateway account and sync subscription URLs and traffic package details.
- To provide remote configuration, analytics, ads, and basic troubleshooting.
5. Local Storage and Security
- Sensitive profile and subscription data is primarily stored locally on your device, using Android-supported secure storage mechanisms where applicable.
- The app does not intentionally store the content of your VPN traffic for its own business purposes.
- If you use a service gateway or a VPN service provider, account status, subscription data, and traffic usage may also be handled on the service side according to that service's logic.
6. Third-Party Services
7. VPN Traffic and Service Packages
- The app mainly acts as a client for connection, profile import, and account synchronization.
- If you use service packages provided by us or our partners, the server side may record package quota, used traffic, remaining traffic, expiration time, and subscription URL to fulfill the service.
- Such records are used for billing, risk control, service activation, and support, and are not sold to third parties.
8. Children's Privacy
If you are a minor, please use the app with the consent and guidance of a parent or guardian.
9. Your Rights
- You may delete local profiles, sign out, revoke camera permission, or uninstall the app at any time.
- You may manage ad personalization settings through your device or Google account where available.
- You may contact us regarding questions, corrections, or deletion requests related to account service information.
10. Changes to This Policy
We may update this Privacy Policy due to product changes, legal requirements, or business adjustments. The updated version will be published on this page with a revised effective date.
