Contact
One address, and it reaches a person rather than a queue.
support@casu.io, for anything at all: questions before you buy, bugs, feature requests, refunds, security reports. It reaches us directly, and we answer as quickly as we can, usually within a day.
Reporting a bug? The settings menu in Casu has a send feedback option that writes the report for you, version and platform filled in; paste it into the email. Security problem? Same address, and please give us a chance to fix it before publishing.
