LockIn

About

You open your laptop to start working. Forty-seven minutes later you're watching a video about how concrete is made.
LockIn fixes that.
Start a focus session and anything not on your allowlist gets blocked — immediately. No loopholes, no "just one quick check." When the session ends, you're notified and your break begins automatically. Then you go again.

PRIVACY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Everything stays in your browser. Settings, stats, allowed sites, and session history are stored locally using Chrome's built-in storage. Nothing is collected. Nothing is sent anywhere.
Permissions used:

tabs & webNavigation — to block distracting sites
scripting — to show session notifications
alarms — to keep the timer accurate even if the popup is closed

No account. No subscription. No tracking.
Lock in and get back to focusing.
