Quiethours: Block focus time on Google Calendar. No meetings allowed.

Hey PH! 👋 I'm the maker of Quiethours. Why I built this: I tried Clockwise. It's powerful — but it requires OAuth access to your calendar and runs everything through their servers. I don't want a third-party reading my meetings. I just wanted a visual reminder of when not to accept meeting invites. What Quiethours does: You define quiet hours directly in the extension — days, time ranges, colors, a label. Quiethours then draws those blocks as overlays on the Google Calendar grid, right in your browser. No OAuth, no sync, no server. If a meeting lands in a focus block, it gets a ⚠️ badge automatically. Everything runs inside the browser tab. Your focus schedule never leaves your device. For people who care about calendar privacy, this is the one alternative where the trade-off is zero. Live on the Chrome Web Store with a free tier (3 focus blocks) and Pro ($5.99/month) for unlimited blocks. I'd love to know: do you currently use any tool to protect deep work time, and what's the biggest friction with your current setup? Thanks 🌙
