We have decided to make DAVdroid free and open-source software (FOSS) because we believe in the openness of the Internet and we want to be a counterpart to all the ones who want to force people to store their private data in "the cloud", using proprietary standards.
However, CalDAV/CardDAV is a very complex topic and development was (and still is) very hard work.
So, although we offer DAVdroid for free (as in freedom), we highly appreciate your support and ask that you either buy it (see Download page) or donate to the project. Thank you!
