Where goes the donation for all developers

I wanted to make a donation, but the address for PayPal is paypal@hexad.dk

hexad.dk is a private/personal site. Where to send donation with PayPal to duplicati community(all developers)?

Hi. You can donate money to the Duplicati project through Open Collective: Contribute to duplicati - Open Collective

Welcome to the forum @AW_Duplicati

Please see the Donations page on the main site.
This is also accessible from the main site home page or upper right corner of the GUI.
PayPal is one of the options, but there are many.

Thank you.
