Privacy Policy — PNG Export for TeamGantt

Last updated: 2026-05-19

Summary

This extension does not collect, transmit, store, or share any user data. Everything happens locally in your browser.

What the extension does

When you click the extension's toolbar icon on a TeamGantt page:

1. It injects a content script into the active tab.
2. The script scrolls the gantt chart programmatically and uses Chrome's chrome.tabs.captureVisibleTab API to take screenshots of the visible viewport at each scroll position.
3. The screenshots are stitched together on an off-screen <canvas> in your browser.
4. The resulting PNG is downloaded to your local Downloads folder.
5. The screenshots and canvas data are discarded.

Data we collect

None. Specifically, the extension does not collect or transmit:

• Personally identifiable information (name, email, address, etc.)
• Health, financial, or authentication information
• Personal communications
• Location data
• Web history or browsing activity
• User activity (clicks, mouse movements, keystrokes, etc.)
• Website content beyond the in-memory screenshots used to produce the PNG you requested

Data we transmit

None. The extension makes no network requests of any kind. It does not contact our servers, analytics services, error-reporting services, or any third party. Project content stays on your device.

Permissions, and why each is required

• activeTab — Lets the extension capture a screenshot of the currently active tab when you click the icon. Access is scoped to that single tab and only for that session.
• scripting — Lets the extension inject its capture script (content.js) into the active TeamGantt tab when you click.
• host_permissions: https://*.teamgantt.com/* — Restricts the extension to TeamGantt domains. The extension does nothing on any other site.

The extension does not request tabs, storage, cookies, webRequest, history, bookmarks, or any other broad permission.

Third parties

The extension uses no third-party services, libraries, SDKs, or analytics.

Changes to this policy

If the extension's behavior changes in a way that affects this policy, this page will be updated and the version in manifest.json will be bumped.
