Open Source

DAVdroid is Open Source as in GPLv3.

Address books, calendars and task list contain private and sensitive data by their nature. We believe that individuals and companies should be able to be in full control of their own data. This means the freedom to choose where and how the data are stored, and freedom in choice of software. CalDAV/CardDAV are open protocols and thus can be used with various server and client software.

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" (say: other people's computers), 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 or donate to the project. Thank you!
