Every marketing email, sales pitch, or newsletter you open sends a signal back when, where, what device, how many times. Klopio blocks that signal at the network level before it ever leaves your device.
Unlike tools that just detect trackers after the fact, Klopio intercepts the request itself. Senders get nothing.
See exactly which companies are tracking you, get a shield badge on tracked emails before you open them, and check your weekly privacy report.
