I believe all international organizations and projects I support from time to time were already mentioned in this thread.
However, there are also some local (German in my case) organizations I have donated to.
1. GFF - Gesellschaft für Freiheit (anti surveillance and pro digital civil rights in the EU and Germany) [1]
2. Frag den Staat (platform enabling easy freedom of information requests in Germany and their publishing in addition to related digital civil rights activities) [2]
