WhoSpies von JIZR

Ever wonder who knows the exact moment you open an email? Sales and marketing tools like Mailtrack, HubSpot, Yesware and Streak embed invisible "spy
pixels" to track you. WhoSpies reveals them — by name.

WHY WHOSPIES IS DIFFERENT
Other extensions just say "a tracker was found." WhoSpies tells you "HubSpot tracked you 7 times, always from contact@company.com." That difference
changes what you can do with the information.

MAIN FEATURES
• Blocks the tracker: neutralizes spy pixels in the message — most effective on Outlook; on Gmail, image proxying may limit it. Three protection levels
(off / balanced / strict).
• Names the service: see the real tracker (Mailtrack, Yesware, HubSpot, Streak, SalesLoft, ActiveCampaign and more) right inside each email.
• History per sender: how many times each person or company tried to track you, and with which tool.
• "Who spies on you most" view: a ranking you can sort by sender or by service.
• Works on Gmail and Outlook web from a single extension.
• Built-in signature catalog: 29 known email trackers plus generic pixels, expanded with each new version.

YOUR PRIVACY, GUARANTEED
All matching and history happen on your device. No email, sender address or personal data ever leaves your browser. You can erase the full history in one
click.

PERMISSIONS
Only local storage access. No unnecessary network permissions, no access to your passwords or browsing history.

SUPPORT
WhoSpies is free. If it's useful to you, you can support development via PayPal or Ko-fi (links inside the extension).
