 Unlike public trackers, it shares peers only within a group using the same announce URL.
 It really works like a private tracker, but can be generated with one click of a button.

+## The Problem PrivTracker Solves
+
+Sharing large files has always been difficult without compromising privacy or simplicity.
+Centralized services require full uploads before sharing, often with account registration and fees for large files.
+Hosting a file server demands technical knowledge, like opening firewall ports, and requires your computer to stay online.
+PrivTracker solves this by enabling private torrent sharing within a trusted group.
+Using UPnP, most torrent clients can automatically handle port opening, and only one person in the group needs an open port for everyone to download.
+Unlike public trackers, PrivTracker shares peers' IPs only within the group and keeps files off public networks like DHT, ensuring privacy and efficient sharing.
