There are different ways to support calcurse development. If you are a programmer, one of the best ways to contribute is to submit patches fixing bugs, adding features or improving overall code quality. We are also extremely grateful for donations which help us continue developing calcurse as open source software and are used to cover recurring costs, such as for our servers.

We use Stripe Checkout to process payments. The Stripe Checkout payment form requires a modern browser with JavaScript support. If you would like to make a donation but do not want to use Stripe, feel free to contact us at <donations at calcurse dot org>. Please also use this email address if you have any questions regarding the donation process.
