While claims can be linked to Kraken accounts, all of the details of the claims themselves are stored on the MtGox trustee servers — not on Kraken servers.
For creditors who filed online, you can view the results on the MtGox claims website. If you are unable to log in, please contact the trustee's help desk as Kraken support staff are unable to help with such issues.
For creditors who filed offline, the trustee will send you an email to notify you.
