As far as I know, SuccessWhale is not being actively used by anyone any more, so I have chosen not to renew the domain name
successwhale.com when it expires today. Like most of my past web-based projects, it will continue to live on at an
onlydreaming.net subdomain, in this case sw.onlydreaming.net, but will not be actively maintained there. As well as its graphical web interface, SuccessWhale also has a back-end API that used to run on a SuccessWhale subdomain. This has now moved to https://successwhale-api.herokuapp.com/. The OnoSendai Android client already uses this address for the API as of update 479, so you may need to update.
Thank you to all the SuccessWhale users over the years!
