How it works

Interrupt the automatic loop

1

Block

Local Chrome rules redirect trigger domains before the page loads.

2

Pause

The Cold Shower page gives you a 60-second delay and a calmer choice.

3

Breathe

Panic breathing moves attention away from the tab and back to your body.

4

Return

Go back to a safer page without uploading the blocked URL.

Features

Focused on privacy and friction

60-second Cold Shower

A calm interruption page gives you one minute before the automatic behavior takes over.

Pledge-based pause friction

Pausing Blockk requires a typed pledge and a short time-limited pause window.

Panic breathing

Open a 4-7-8 breathing guide from the popup or the block page.

Local streak

Progress lives in your browser storage, not on a server account.

Custom blocklist

Add the domains that trigger you and keep the list on your device.
