A porn blocker that runs on your computer, not on a company’s server.

cocloc blocks porn sites at the network layer, on your own machine. There is no server of ours in the loop. We never receive your screen, your traffic, or your history.

And on cocloc Lock, when you go to switch it off, it makes you wait 24 hours.

That wait is the product.

cocloc Lock · request #4 — turn protection off
23:41:18

Filed at 01:14. Confirm unlocks when the wait is done. Cancel works right now.

Join the waitlist

Early access is rolling out in small batches. Free and Lock both start from the waitlist. Windows 11 · 18 and over.

What early access looks like

The one asymmetry

Making it stronger is instant. Making it weaker takes a day.

Everything else in cocloc follows from this. You are never blocked from protecting yourself harder, and on cocloc Lock you are never able to protect yourself less on impulse.

Applies now

Tightening

Takes effect the moment you ask. No wait, no confirmation, no friction, ever. On both tiers.

  • Add a site to the blocklist
  • Turn a layer back on
  • Extend the gate past 24 hours
  • Bring a paused blocker back on
Waits 24 hours on Lock

Loosening

The request is filed now and can only be confirmed tomorrow. You can cancel it at any point before then. On cocloc Free there is no wait: pause is instant.

  • Pause protection
  • Unblock a site
  • Turn a layer off
  • Uninstall cocloc

What is built, and what is not

How it blocks

At the network · in this build

Refused before the page loads

Blocked domains are written into the Windows hosts file, so they fail to resolve for every browser and every app on the machine, including private windows. cocloc also turns DNS-over-HTTPS off in Chrome, Edge, Brave and Firefox, because a browser resolving DNS inside itself would route straight around the hosts file. Nothing is decrypted. No certificate is installed.

On the screen · coming

Not in this build

Screen detection is coming: a small model on your own disk, looking for explicit content a domain list structurally misses. It is not in the product today. There is no screen capture, no model running and nothing drawn on your screen. We would rather say that here than sell you a page of it.

The blocklist that ships is 121 domains, hand-curated, plus a 15-domain never-block list for health, recovery and education. It covers the majors. It is not exhaustive, and it never will be.

Privacy

What leaves your computer

On cocloc Lock: four things, and no others.

  • 01

    The payment you made to buy it.

  • 02

    An email, if you write to support.

  • 03

    If — and only if — you name an accountability partner: events. “Uninstall requested at 01:14.” Partner alerts are coming, not built.

  • 04

    A periodic licence check: your licence key and a random install id, so we know the subscription is live.

    That fourth one is not an account and not a profile. It carries nothing about what you did: no browsing, no screen, no domains you visited or tried to visit.

On cocloc Free it is one thing: an email, if you write to support. No payment, no licence check, no partner.

No screenshots. No decrypted traffic. No browsing history. Not to us, not to your partner.

Stated plainly

What cocloc will not do

Every blocker has these. Most don’t print them on the front page.

  • ×
    It will not cover your phone, your tablet, or your work laptop.

    Windows 11 desktop and laptop only. Windows 10 has never been tested. That’s a limit, and we’d rather name it than hide it.

  • ×
    It will not stop a VPN, a raw IP address, or a browser pointed at a DNS provider we don’t cover.

    Those are the three routes around a hosts file, and all three still work. We name them because you will find them anyway.

  • ×
    It will not watch your screen. Yet.

    Screen detection is coming. It is not in this build, so a feed, a timeline or a video on a site we cannot block wholesale goes through untouched today.

  • ×
    It will not stop someone who holds their own admin account and knows what they’re doing.

    You stay an administrator on your own machine. cocloc does not take that away. It makes removal slow, deliberate and logged. It does not make it impossible.

  • ×
    It will not watch someone else’s device.

    Not a parental-control tool. Different job, different software.

Free, or locked

The paid thing isn’t features.

cocloc Free$0

It’s commitment.
