We do not take fees. If you choose to donate to a specific charity, 100% of your donation will be earmarked to be granted to the charity of your choice. However, some payment processors charge a small fee which is deducted from your donation and thus does not reach the recipient charity. Learn more here.

Donations are tax deductible for donors in the USA (via bank transfer), the United Kingdom (via bank transfer), Germany, Switzerland, and the Netherlands.
