When you register a Wickr ID you are the only one that knows that ID. We've purposely built an abstraction layer preventing us from getting this information.
Your Wickr ID, along with all other user and device information related to your account, is irreversibly encoded with multiple rounds of salted cryptographic hashing prior to being sent to our servers.
This means that even we cannot determine the actual information based on the hashed values we store.
We also don’t force you to share an email address or other personal information that could identify you to us or other Wickr users.
