How do I install CatBlock?

Download the package from the install page and follow the four steps to load it in Chrome, Edge, Opera, or Brave. It takes about a minute.

Is CatBlock really free?

Yes, free for 7 days with every feature unlocked. After that it’s $2.99/month. No card required to start.

What happens when the free trial ends?

Blocking pauses and detected ad slots show our own “upgrade to keep blocking” notice. No ads are secretly re-injected and no traffic is proxied. Upgrade any time to switch blocking back on.

Does CatBlock see my browsing history?

No. Blocking happens on your device and your browsing never leaves it. We only contact our licensing API and payment provider.

Which browsers are supported?

Any Chromium-based browser on desktop: Chrome, Edge, Opera, and Brave. More platforms are on the way.

How do I cancel?

Open your account and cancel in two clicks. You keep access until the end of the billing period.
