No. From what I understand, hashify does no intensive server side processing beyond providing the functions that allow the visitor to process the encoded string on its end; i.e., all intensive processing is done on the client's side.

But as people above mentioned, the data is still being uploaded unnecessarily, due to a little short sightedness by the hashify creator(s). The hash should be stored after a pound (#) character to ensure that the data isn't sent to the hashify server via the URL (i.e., the GET method), since all processing of the hash is done client-side anyway.
