Local-only
lunch protection.
A Chrome extension that writes realistic-looking calendar events into your lunch window each morning. Different titles, different durations, different start times every day. Nothing leaves your browser.
What the extension does
Writes 1–3 events into your lunch window each morning
You define the window (default 11:30 AM to 1:00 PM). The extension generates events at startup and dormant after.
Realistic titles drawn from a curated pool
Vendor Sync, Pipeline Review, 1:1 — Product Brief, Roadmap Read, Hold — Brief, Design Crit, and dozens more. Coworkers see business meetings, not lunch blocks.
Varied durations and start times
25 to 60 minutes per event. Start times shift within your window. No two consecutive days have the same set.
Anti-pattern logic
Tracks recent titles, durations, and times. Prevents detectable repetition that would let coworkers learn your pattern.
One-click clear
The popup has a 'Clear all CovertLunch events' button. Removes every event the extension wrote, in bulk.
What it does not do
- —Read your existing meetings. The OAuth scope is write-only.
- —Send your calendar data anywhere. There are no CovertLunch servers.
- —Move existing meetings or reschedule conflicts. Single-purpose tool.
- —Sync across browsers. Each browser install is independent.
- —Support Microsoft 365. For that, see the cloud service.

Is this safe to install?
Yes. The extension is Manifest V3 (the current Chrome standard), uses write-only OAuth scope (it cannot read your existing meetings), and runs entirely in your browser. The source is auditable from the Chrome Web Store package.
What permissions does it need?
Only the calendar.events OAuth scope, which grants the ability to create new events on your calendar. It cannot read, modify, or delete events it did not create itself.
Does it work on Edge, Brave, Arc, or Opera?
Yes. Any Chromium-based browser that supports Chrome extensions can install it. The functionality is identical.
Will it slow down my browser?
No. The extension runs once per day in the background to generate events, then is dormant until the next day. No persistent processes, no DOM injection on other tabs.
What happens if I uninstall it?
Future event generation stops immediately. Existing events that were already written to your calendar stay there until you delete them manually. The extension popup has a 'Clear all CovertLunch events' button if you want to remove them in bulk.
Does it work with Google Workspace?
Yes, including Business Standard, Business Plus, Enterprise, and Education editions. Also works with personal Gmail accounts.
