I'm sorry but i need sinchronice calendars to nextcloud and Davdroid is working good but i need buy licenses how old software, i don't want buy in a google or amazon market, i need buy in a computer with paypal/credit card download the software and after install in phones, i not want buy in a smartphone, how can i buy "traditional" license
sorry we can't sell licences manually - it's too much of a work for us to make invoices for such a small price. Alternatively I can suggest to download our free open source version from f-droid.org, so that you can automatically get updates when we're releasing new versions. If you choose this method we'd be happy to receive a donation of course
Thanks and best regards!
