Antigravity Annotator is a browser extension designed to let you capture a full screenshot of the
current webpage, crop and annotate it with drawing tools, highlights, comments, and text, then seamlessly send the
result—along with context prompts—directly to your IDE. Built for designers and developers who need a fast, local
feedback loop between the browser and their development environment.
Privacy Summary: Antigravity Annotator does not collect, store, or transmit any personal data to
external servers. All data stays on your local machine.
1. What Data We Access
When you click the extension icon, Antigravity Annotator:
Captures a screenshot of the currently visible browser tab using the Chrome captureVisibleTab API.
Injects a content script into the active tab to display an annotation overlay, allowing you to draw and add
comments on the screenshot.
2. How Data Is Used
The captured screenshot and your annotations are used solely for the purpose of enabling the annotation workflow.
Specifically:
The screenshot image is held in memory within the browser tab and is never saved to disk or uploaded to any
remote server.
When you choose to "Send to IDE", the annotated data is sent to a local server running on your own
machine (typically localhost:3001). This is your local development environment — no data
leaves your computer.
3. Data Collection
Antigravity Annotator does not:
Collect any personal information (name, email, browsing history, etc.)
Use cookies or any tracking technologies
Send analytics or telemetry data to any third party
Store any data beyond the current browser session
4. Permissions Explained
activeTab: Required to capture a screenshot of the tab you are currently viewing when you click
the extension icon.
scripting: Required to inject the annotation overlay UI into the active tab.
host_permissions (<all_urls>): Required so the extension can work on any webpage you wish
to annotate. The extension does not read or modify page content — it only overlays the annotation UI on top.
5. Third-Party Services
This extension does not integrate with any third-party services, advertising networks, or analytics platforms.
6. Data Security
Since all data remains on your local machine and is never transmitted to external servers, there is minimal risk of
data exposure. The local communication between the extension and your IDE uses standard HTTP on localhost.
7. Changes to This Policy
If we make changes to this privacy policy, we will update the "Last updated" date above. Continued use of the
extension after changes constitutes acceptance of the updated policy.
