The membership fee can be freely chosen and either paid directly into our bank account, or conveniently deducted from your account via our electronic donation form below.

Your membership can be cancelled at any time and without explanation.

As a member, you will receive regular updates on the progress of the project.

For every donation you will automatically receive a (German) tax receipt, provided we have your postal address. Even electronically issued tax receipts sent out via mail, require a postal address.

Tax receipts without a postal address are not legally valid!

To avoid high costs, we automatically send out all tax receipts in bulk in January of the following year. Should you need your tax receipt immediately, please let us know and we will gladly send it to you.
