ViewGraph Browser Extension Last updated: April 19, 2026

Summary

ViewGraph does not collect, transmit, or store any personal data. All captured data stays on your local machine.

What Data the Extension Accesses

When you click the ViewGraph toolbar icon on a page, the extension reads:

  • DOM structure (HTML elements, attributes, computed styles)

  • Element bounding boxes and layout information

  • Accessibility attributes (ARIA roles, labels)

  • Network request status (success/failure, not request bodies)

  • Console errors and warnings

  • Client-side storage keys and non-sensitive values (localStorage, sessionStorage, cookies). Values that look like tokens, passwords, or keys are automatically redacted and never captured.

  • CSS custom properties (variables defined on the page)

  • Your annotations (comments you type, severity, category)

Where Data Goes

All captured data is sent only to a server running on your local machine (localhost, ports 9876-9879). The extension never contacts external servers, cloud services, or third-party APIs.

The data flow:

What We Do NOT Collect

  • No personal information

  • No browsing history

  • No cookies or authentication tokens from visited pages (storage keys are captured but sensitive values like tokens, passwords, and API keys are automatically redacted)

  • No request or response bodies

  • No data sent to external servers

  • No analytics or telemetry

  • No user accounts or registration

Data Storage

  • User preferences (capture settings, auto-capture toggle) are stored in chrome.storage.local and chrome.storage.sync, both local to your browser

  • DOM captures are stored as JSON files in your project's .viewgraph/captures/ directory

  • Screenshots are stored alongside captures on your local disk

Third-Party Services

ViewGraph uses no third-party services, analytics, or tracking. The extension is fully self-contained.
