 # `EpicTracker`
 Demo: https://epictracker.now.sh
 - It is a demontstration project of how can I track you using [device fingerprinting](https://en.wikipedia.org/wiki/Device_fingerprint) and some automated lookups and stuff.
-- 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.
