# Extended Data Storage

**Extended data** is discarded 28 days after the date of the test that recorded it.  
  
Extended data is any additional information that is kept and stored along with the normal results that are contained in a test. Extended data currently includes screenshots of the page encountered during an error, and the full URL and IP Address of the file that the error was associated with. Do note that the generic error message associated with a failure is never discarded and never compressed.
