* '''Supercookies.''' This refers to a collection of techniques that involve storing tracking identifiers in areas of the browser that are not cleared when the standards-defined locations are cleared. This allows a tracker to re-establish a tracking identifier after a user or user agent clears storage. For example, a party which uses multiple domains to encode a tracking identifier in HTTPS Strict Transport Security flags would be considered to use supercookies.
