PhantomProxy collects nothing. It does not transmit, store, or share any data about you or your browsing activity with anyone — including the developer. Everything stays inside your browser.
PhantomProxy is a browser DevTools extension for Microsoft Edge that allows developers and security researchers to inspect, filter, and replay HTTP requests made by the browser. This policy describes what data the extension accesses, how it is handled, and what it does not do.
This policy applies to the PhantomProxy extension distributed via the Microsoft Edge Add-ons store.
To function, PhantomProxy observes HTTP traffic within your browser tab via the browser's built-in webRequest API. This means the extension can see:
| Request URLs | The full URL of each HTTP request made by the browser tab |
| HTTP Methods | GET, POST, PUT, DELETE, etc. |
| Request Headers | Headers sent with each request (e.g. Authorization, Content-Type, Cookie) |
| Request Bodies | POST/PUT body content, capped at 64 KB per request |
| Response Status | HTTP status codes and response headers |
| Timing | Request duration in milliseconds |
| Storage location | In-memory only, inside your local browser process |
| Persistence | Data is cleared when you close the DevTools panel or navigate away. Nothing is written to disk by the extension |
| Transmission | NEVER No data is sent to any server, API, or third party |
| Sharing | NEVER No data is shared with the developer or any other party |
| Analytics / telemetry | NONE The extension contains no analytics, telemetry, or crash reporting |
| Advertising | NONE No advertising SDKs or tracking pixels are included |
| Maximum stored requests | 500 requests at a time (oldest entry dropped when limit is reached) |
The Repeater tab allows you to manually edit and re-send HTTP requests to a target URL of your choosing. These requests are sent directly from your browser to the target server — they do not pass through any server operated by PhantomProxy or its developer.
You are solely responsible for the requests you choose to send using the Repeater. Use this feature only against systems you own or have explicit permission to test.
| webRequest | To observe HTTP traffic in the browser tab — the core function of the extension |
| tabs | To identify which tab's traffic to display in the DevTools panel |
| storage | To persist user preferences (such as filter settings) across DevTools sessions |
| scripting | To support DevTools panel integration with the inspected page context |
| webNavigation | To detect page navigation and correctly handle request lifecycle boundaries |
| <all_urls> | To observe requests to any domain — necessary because users test against arbitrary endpoints |
PhantomProxy does not integrate with, communicate with, or share data with any third-party service. There are no embedded SDKs, no external fonts loaded at runtime, and no outbound connections made by the extension itself.
PhantomProxy is a developer tool intended for adults. It is not directed at children under the age of 13. Since no personal data is collected, no special provisions for children's data apply — but the extension is not designed or marketed for use by minors.
If this policy changes in a future version of the extension, the updated policy will be published at this URL and the effective date above will be updated. Continued use of the extension after a policy update constitutes acceptance of the revised policy.
Since the extension collects no data, any future changes are expected to be minimal and will only reflect new features or permission changes, not new data collection practices.
