Anonyome is not able to trace a Sudo email address back to a legal identity. This is because you never provide your name, address and other personally identifiable information at registration.
Within the data retention period (24 hours), a law enforcement official who obtains the IP addresses related to use of a Sudo account may be able to trace those IP addresses back to a legal identity, via a subpoena to a telecommunications provider or app store provider.
*A legal identity is typically a set of attributes assigned by a central authority to acknowledge, record, and validate a human being’s existence within a given social context. In the United States, examples of this would be a birth certificate, a social security number, or a passport.
