Block distracting websites. We never see your browsing history.
BlockCalm is a website blocker and focus timer for Chrome that runs entirely on your own device. Build your own blocklist, use preset packs for the usual time-sinks, set scheduled blocking hours, and run focus sessions — with no account and no tracking.
Why BlockCalm
- Private by design: the extension makes zero network calls and contains no analytics or telemetry. Your blocklist and settings live only on your device.
- Blocks what actually distracts you: whole sites, or just the addictive parts — like youtube.com/shorts or instagram.com/reels.
- Schedules and focus timer: blocking that turns itself on for work hours and off when you're done.
- Delay-unlock: when you really need a blocked site, you wait out a countdown first — friction, not a wall you rage-quit.
- One-time price, no subscription: see Pricing.
How it works
Add a site to your blocklist and BlockCalm sends you to a calm block page instead. Everything happens locally in your browser — there is no BlockCalm server, no sign-up, and nothing about your browsing ever leaves your machine.
