Privacy Policy for WebRadar

WebRadar is a browser extension that overlays developer-focused diagnostics on web pages: frame rate, memory usage, computed CSS, network and console activity, page weight, and similar measurements. It is a local, on-device developer tool.

Data Collection and Use

WebRadar does not collect, store, transmit, or share any personal or non-personal user data.

All measurements (FPS samples, memory readings, CSS lookups, console captures, network observations) are computed locally within your browser. They are displayed in an in-page overlay or the extension popup and are not sent to any server, telemetry endpoint, or third-party service by WebRadar.

WebRadar inspects the current page's DOM, performance APIs, console output, and resource list to produce its measurements. That inspection is read-only with respect to your data: the extension does not read keystrokes, form values, cookies, or authentication state, and does not retain page content beyond the transient samples needed to render the overlay.

Permissions

WebRadar requests the permissions necessary to inject its overlay and read performance-related browser APIs. It does not request, and does not use, permissions for browsing history, identity, or cross-site tracking.

Third-Party Access

WebRadar does not provide access to your data to any third parties. Because WebRadar does not collect or transmit any information, there is no data available to be shared, sold, or analyzed.

Security

Because WebRadar operates fully on-device and does not transmit any data externally, the risk of data exposure through the extension is effectively eliminated. The overlay modifies the displayed view of the current page only, and is rendered in browser memory and removed when the page or the extension is closed.

Open Source Commitment

WebRadar is built on top of the open-source WATT3D JavaScript stack. Source for the extension itself lives at github.com/iWhatty/fps-devtools-js and is open for community inspection.

Changes to This Policy

This Privacy Policy may be updated in the future, particularly if new features change how data is processed. Significant changes will be reflected here and announced where appropriate within the extension.
