FocusLock is a strict productivity Chrome extension that blocks distracting websites for a fixed duration — with no option to unlock early.
Once you lock a site, you're committed until the timer ends. No cheating.

You decide once — and commit.
- Users could still disable the extension manually via Chrome
- Works best when you commit to using it honestly
