This page tests browser-fingerprinting using the AudioContext and Canvas API.
Using the AudioContext API to fingerprint does not collect sound played or recorded
by your machine - an AudioContext fingerprint is a property of your machine's audio stack
itself. As of March 31st, 2018 this test page no longer saves fingerprints for
research purposes. When you view your fingerprint, no data is transferred to us.
We also test a form of fingerprinting using Flash if you have Flash enabled.
