About Klopio — Detect & Block Email Tracking in Gmail

Protect Gmail Privacy: Block Email Tracking Pixels, Spy Pixels & Read Receipts Every time you open a marketing email, a sales pitch, or a newsletter, the sender finds out instantly. When you opened it. Where you are. What device you used. How many times you read it. All without asking your permission. Klopio stops that. It blocks tracking pixels in Gmail before senders get any signal that you opened their email. Everything runs on your device. Your emails never touch our servers. ✔️ SPY PIXEL PROTECTION When you open an email, Klopio stops tracking requests before they ever leave your device. Senders get no signal that you opened their email. No timestamp, no location, no device info. Trackers are stopped before they have a chance to load. ✔️ TRACKER IDENTITY LAYER Most tracker blockers just tell you an email was tracked. Klopio tells you who did it. Instead of a cryptic web address, you see the actual company watching your inbox. Apple News, Nike, LinkedIn, your real estate agent, that SaaS tool you trialed last month. You always know exactly who is watching. ✔️ INBOX WARNING BADGES A 🛡️ shield badge appears on emails from senders that use tracking pixels, so you know before you open them. No surprises. ✔️ WEEKLY PRIVACY REPORT Each week, Klopio shows you how many trackers were blocked, how many of your emails were tracked, and which companies did it most. Share your report directly to social media. ✔️ YOUR EMAILS NEVER LEAVE YOUR DEVICE Everything happens on your computer. Klopio never reads your emails, never sends them anywhere, and never stores them. Gmail access only. No other websites. No ads. No data selling. WHO USES KLOPIO Personal privacy: Stop marketers and newsletters from knowing when you read their emails. Professionals: Lawyers, recruiters, and executives keep reading habits private during negotiations and sensitive communications. Freelancers: Do not hand over leverage. If a client knows you read their offer three times in one hour, that is information you did not choose to share. Teams: Reduce third-party tracking exposure and support GDPR compliance across your organization. 30-DAY FREE TRIAL. NO CREDIT CARD REQUIRED. Full access to every Pro feature from day one. No payment information needed to start. When the trial ends, all features are suspended until you upgrade. Most users are surprised by how many companies were watching them. That is exactly why they stay. Pro starts at $3.99 per month or $29 per year. Your inbox. Your rules. Pricing: https://klopioapp.com/#pricing IS IT SAFE? Klopio runs entirely on your device. It never reads what is in your emails. It only intercepts tracker requests, nothing else. Gmail access only, limited to mail.google.com and Google image servers No email content is ever read or transmitted No personal data is collected or sent anywhere No ads. No tracking of any kind. Tracker blocking happens at the network level before tracking requests ever fire. PRIVACY POLICY https://klopioapp.com/privacy SUPPORT support@klopioapp.com klopioapp.com
