Some sites justshouldn't open.

Add a site and it stops loading. The list can't be changed without your 6-digit PIN — and when it is time, you can unlock one site for fifteen minutes without unlocking the rest.

What it does

Block the noise, keep the focus.

Block any site

Add a website and it stops opening. The page never loads, so there are no ads and nothing pulling anyone back in.

6-digit PIN lock

The blocklist can't be changed without your PIN, stored only as a salted hash on your device.

Unlock for a while

Enter your PIN on the blocked page to open a site for 15 minutes or an hour. It re-locks itself.

One-tap suggestions

YouTube, TikTok, Instagram, Reddit, Roblox, Discord — add the usual distractions in a single tap.

A calm blocked page

Visitors see a plain notice instead of the site. No browser error, no ads, no recommendations.

Optional PIN hint

Set a private hint in case you forget. There is no recovery — the PIN itself is never stored.

Privacy

Nothing leaves the browser.

NotNow makes no network requests. Here is the complete list of what it writes to your device — there is no other copy, and no way for us to read this one.

  • Your blocked websites.
  • A salted PBKDF2 hash of your PIN (the PIN itself is never stored).
  • Your optional PIN hint, if set, and the expiry time of any temporary unlock.
