Privacy Policy — GCal WorkShade

Last updated: 2026-06-08

Summary

GCal WorkShade is a browser extension that visually shades non-working hours and weekends on Google Calendar. It runs entirely inside your browser. It does not collect, transmit, sell, or share any personal data, browsing activity, or calendar content — with anyone, ever.

What the extension does

The extension injects a visual overlay onto the Google Calendar page (calendar.google.com) that dims the time slots outside the work hours you configure, and optionally dims Saturday/Sunday columns. It reads the page's layout (the position and size of the calendar grid) purely to draw this overlay in the correct place — it never reads, stores, or transmits the content of your calendar (events, titles, attendees, locations, etc.).

What information is stored

The only information the extension stores is your display preferences:

• Work start time and work end time
• Whether off-hours shading is enabled
• Whether weekend shading is enabled
• Shading intensity (opacity)

These settings are stored locally using the browser's built-in chrome.storage.sync API. If you are signed into your browser, this storage mechanism syncs the settings across your own devices — this sync is handled entirely by your browser vendor (e.g. Google, Microsoft), not by us. We have no access to this data, and no server of ours is ever contacted.

What information is NOT collected

• No calendar data (events, titles, times, attendees, locations)
• No personal identifiers, names, or email addresses
• No browsing history or activity outside calendar.google.com
• No analytics, telemetry, or crash reporting
• No cookies, fingerprinting, or tracking technologies of any kind

Network requests

The extension makes zero network requests. It does not communicate with any server — ours or any third party's. All processing happens locally in your browser.

Third parties

The extension does not integrate with, embed, or share data with any third-party service, advertiser, or analytics provider.

Permissions explained

• storage — used solely to save your display preferences locally on your device (and sync them via your browser's own account sync, if enabled).
• Access to calendar.google.com — used solely to display the visual shading overlay on the calendar page. The extension does not read or modify any calendar content.

Changes to this policy

If this policy changes, the updated version will be posted at this same URL with a revised "Last updated" date.
