How does Blocker stop a site or app from opening?

Sites get dropped at a small proxy that runs on your Mac itself, so the page won’t load in any browser. Apps are watched by a small helper: when one on your blocklist tries to launch, it’s hidden and closed on the spot. Nothing destructive, no files touched.

I always cave and unblock. How do the lock modes stop me?

Each block has a lock mode. Off lets you pause or stop after a short wait. Strict makes that wait longer and makes you type “I want to break my focus” to quit early. Hardcore can’t be stopped until the timer ends, with one emergency pass a week. Pick the mode for how weak you’ll feel later, not how strong you feel now.

Does Blocker read my browsing?

No. To serve the blocked page over HTTPS, Blocker installs one local certificate that does a single job: show the blocked page for sites on your list. Sites you haven’t blocked are never read, decrypted, or logged. There’s no account, it runs offline, and nothing about your browsing leaves your Mac.

Does it work in every browser, plus Mac apps?

Yes. Every browser and every Mac app. You don’t need to add anything inside the browser. Add a domain and every subdomain, like m.youtube.com, goes with it.

Do I need an account, the internet, or any setup?

No account, no sign-up, and it runs offline. Setup takes a minute: to show the blocked page over HTTPS, Blocker installs one local certificate, which needs a single Mac approval with Touch ID or your password. That’s the only prompt, and blocking still works if you skip it.

How is this different from Screen Time or a browser add-on?

Screen Time can block apps but is awkward to schedule. Add-ons only cover one browser, and you slip past them by opening another. Blocker covers every browser plus Mac apps in one place, and the lock modes mean you can’t just switch it off the moment the urge hits.

Is there a free version?

There’s a 7-day free trial with every feature on. After that the app stops blocking until you buy a licence, one time. You only pay if you decide to keep it.
