Tabbycat is a volunteer effort. Since 2012, its maintainers have spent thousands of hours working on it.
Donating to Tabbycat helps the maintainers to meet recurring costs and justify our ongoing contributions in responding to support enquiries, keeping the software up to date, fixing bugs, and developing new features.
We suggest that tournaments budget for a donation of A$1 (Australian dollar) per team. For tournaments run for fundraising or for profit, whether partly or solely, this payment is required and your licence to use Tabbycat is conditional upon it. General donations from individuals or organisations are of course also much appreciated.
