Tracking Unique Visitors Without Cookies: The Margin Approach

Tracking unique visitors without cookies

I explore why traditional cookies and localStorage fail under modern privacy laws and why fingerprinting is ethically dubious. Instead, I explain how Margin uses server-side hashing to count unique visitors without storing device data. While this method sacrifices cross-day tracking, it offers a transparent trade-off where your infrastructure handles the raw data, ensuring the vendor never sees your visitors' IP addresses.
