01

Install Klopio

Add to Chrome in one click. Your 30-day trial starts immediately with full access.

Features

Everything you need.
Nothing you don't.

🚫

Network-Level Blocking

Tracker requests are intercepted before they ever reach the sender's server. Senders get no signal that you opened their email.

🏢

Tracker Identity

See the company name — not a raw web address. Klopio blocks 500+ email trackers by name — from major marketing platforms to custom sales tools.

Inbox Warning Badges

A shield badge appears on email rows before you open them — so you always know which senders track you.

📊

Weekly Privacy Report

A rolling 7-day report shows how many trackers were blocked, which emails were tracked, and which companies tracked you most.

🔒

Gmail-Scoped Only

Klopio only requests access to Gmail — never all websites. We block trackers without becoming one.

⚡

Always Up to Date

Built on Chrome's current extension standard. Fully compliant, future-proof, and works in all modern Chrome versions.

Why Klopio

Built different.
By design.

Most email privacy tools compromise somewhere. Klopio doesn't.

🏗️

Always Works in Chrome

Klopio is built on Chrome's current extension standard from day one. No deprecated code, no workarounds — it works today and will keep working.

🔒

No Server Sees Your Emails

Your emails never leave your device. All processing happens locally — we block trackers without becoming one.

🎯

Minimal Permissions

Klopio only requests access to Gmail. We never ask for access to all websites. Minimum permissions, maximum trust.

🏢

Names, Not Just Addresses

See the company behind every tracker — not just a web address. You always know exactly who is watching your inbox.

Privacy Promise

We block trackers without becoming one.

Klopio runs entirely on your device. Your emails never leave your computer. Tracker blocking happens at the network level locally — no data is routed through external servers, no email content is ever read or transmitted.

FAQ

Common questions.

Does Klopio work with Outlook or Yahoo Mail? +
Klopio currently works with Gmail only, accessed via mail.google.com in Chrome. This includes Google Workspace accounts. Support for other email clients may come in a future version.
Does Klopio block all tracking pixels? +
Klopio blocks over 500+ email trackers. New trackers appear constantly — Klopio catches the vast majority but no tool can guarantee 100% detection of every tracking method.
Can the sender tell I'm using Klopio? +
No. When Klopio blocks a tracking pixel, the sender receives no signal. To them it appears as if you never opened the email. Klopio is completely invisible to senders.
Does Klopio read my emails? +
No. Klopio only scans image URLs within emails to identify tracking pixel patterns. It never reads email content, subject lines, or sender addresses. All processing happens locally on your device.
What happens after the 30-day trial? +
When the 30-day trial ends, all Klopio features are suspended. The service will not function without an active paid subscription. No free tier is offered after the trial period ends.
Is my email data safe with Klopio? +
Yes. Klopio runs entirely on your device. Your emails never leave your computer. No email content is ever read, stored externally, or transmitted to Klopio's servers. We only access Gmail to scan for tracker URLs — nothing else.

Your inbox deserves privacy.
