Focus Lock — Website Blocker

Focus Lock blocks distracting websites for the duration of a focus session. The difference from other blockers: Hard Mode actually works. There is no "5 more minutes" button, no settings menu to disable it mid-session, and the block survives a browser restart. When you commit to a session, you commit. WHAT IT DOES - Block sites for a chosen duration (25 minutes, 1 hour, 2 hours, 4 hours). - Hard Mode — a session that cannot be stopped early, even by restarting Chrome. - Whitelist mode — block every site EXCEPT the ones you list, useful for deep work where you only need a few specific tools. - Schedules — set recurring blocks that start automatically (e.g. block social media every weekday 9am-12pm). - Stats — daily focus minutes, weekly totals, day streak, 14-day chart. - Optional friction — answer a few quick math problems to end a regular session early. Off by default. Turn it on if you want a speed bump against impulsive breaks. WHY THIS EXTENSION EXISTS Most blockers have a way to disable them in three clicks. That's fine if you have unlimited self-control, but the whole reason most people install a blocker is that they don't. Focus Lock is built around one idea: the friction of bypassing the block should be greater than the urge to bypass it. HONEST LIMITATIONS - Hard Mode can be bypassed by uninstalling the extension. Chrome doesn't allow extensions to prevent their own uninstall. It is still significantly harder than clicking a button. - Scheduled sessions are checked once per minute, so a session may start up to 60 seconds after its scheduled time. - Whitelist mode is aggressive: if you don't add google.com to your allowed sites, any "Sign in with Google" flow on other sites will be blocked. Adjust accordingly. - All data is stored locally in your browser. Nothing is sent to any server. This also means stats and schedules do not sync across devices. PRIVACY Focus Lock does not collect, store, or transmit any user data outside your own browser. Your blocklists, schedules, and stats live in chrome.storage.local on your device and nowhere else.
