 # EpicTracker [ip-sniff]
 Demo: https://epictracker.now.sh
 - It is a demontstration project of how can I track you using fingerprinting and some automated lookups and stuff.
-- It uses modern Javascript APIs to intentify your metadata and keeps the information in a cookie, encrypting it.
+- It uses modern Javascript APIs to intentify your metadata and generates an SHA-1 hash based on it. The hash can be used to further identify the browser even after clearing the cache or using the demo in private browsing mode.
 - I will make a machine learning algorithm in future which will try to match the encrypted cookies to figure out the target.
 - I may create dummy marketing services to demonstrate the (targeted ads) tracking process close to the realworld.
