Interceptor | Network Debugger

Network Traffic & Secure VPN

Free · Designed for iPad. Not verified for macOS.

Inspect selected Nintendo HTTPS traffic on your device. Review sensitive-data handling and consent before capture; withdraw consent in Settings to stop it. Interceptor helps you inspect selected Nintendo-related HTTPS traffic on your own iPhone or iPad. View saved request and response headers, cookies, and available JSON bodies, and inspect supported service tokens. The app uses an iOS VPN configuration to direct selected hosts through a proxy running on your device. It does not provide a remote VPN server, change your public IP address, or protect public Wi-Fi traffic. HTTPS inspection requires you to install and trust a locally generated certificate authority certificate in iOS Settings. At startup, Interceptor explains what it can access and requires agreement to the current data-use notice before you can access the main interface. Agreement alone does not start capture, install a certificate or VPN configuration, or request notification permission. Captured traffic can contain sensitive cookies, authentication tokens, account identifiers, and request or response content. Use it only with accounts and devices you are authorized to inspect. Capture is limited by the app's configured Nintendo-related hosts; service changes or certificate restrictions may prevent capture. New capture records are stored in the app's local shared storage. New certificates, private keys, and saved tokens use Keychain items with iCloud Keychain synchronization disabled. Interceptor does not upload captured data to a developer-operated server, sell it, use it for advertising, or automatically share it with third parties. Nintendo requests still reach their original Nintendo services. Data you choose to copy, earlier iCloud Keychain copies, and operating-system backups are separate from this local capture flow. You can review the notice and withdraw consent in Settings → Privacy. Withdrawal stops the VPN, disables automatic reconnection and clears capture notifications, and returns to the required consent screen until you agree again. Withdrawal does not erase saved records, tokens, certificates, or private keys, or remove an installed certificate profile. Clear saved request history from Home. Optional local notifications announce captured records without including tokens or captured headers and bodies in the notification. An independent tool, not affiliated with or endorsed by Nintendo.
