Privacy Policy — Network+

Last updated: 2026-07-02

Summary

Network+ does not collect, store, transmit, or share any user data. Everything the extension reads or writes stays on your local machine.

What the extension does

Network+ adds a custom Network panel to Chrome DevTools. To do its job it observes network activity on the page you are inspecting:

It captures HTTP requests via the standard chrome.devtools.network API (the same data the built-in Network panel sees).

It patches window.WebSocket, window.fetch, and XMLHttpRequest in the inspected page (via a content script running in the MAIN world) so it can record WebSocket frames and apply the user-configured mocks / delays / WS-frame sends.

These observations are processed entirely in-memory inside Chrome DevTools and the inspected page on your machine.

What is stored locally

The extension uses chrome.storage.local to persist your own settings between DevTools restarts:

URL prefixes, type filters, font size and overlay UI preferences.

Mock rules you create.

Delay rules you create.

WS-frame templates you save.

This data lives only in your browser profile. It is never sent to any remote server by Network+.

What is NOT collected

No analytics, telemetry, crash reports, or usage tracking.

No remote logging.

No account, identifier, fingerprint, or device data.

No advertising or third-party SDKs.

Permissions and why we need them

storage — to save the settings listed above on your machine.

<all_urls> host permission + content script — required to install our WebSocket / fetch / XHR patcher in the inspected page. Without broad host access the patcher cannot intercept WS frames or apply user-defined mocks. The patcher does not send any captured data anywhere — it only feeds the local DevTools panel.

Network access

The extension itself makes no outbound network requests of its own.

Third parties

None. The extension has no third-party dependencies, SDKs, trackers, or remote services.
