If you like Docear, we kindly ask you to donate which greatly helps ensuring the future development of Docear. Although we, i.e. the core team, have a scholarship, which covers the basic living costs, your donation is greatly needed. There are expenses for servers (for this website, the recommender system, the online backup service, etc.), external freelancers (e.g. Docear4Word was developed by a freelancer whom we paid), and students who support us occasionally. Most of these expenses are paid by us and during the past years this accumulated to quite a bit of money. Since Docear is free and open source and we are not generating any income (and our scholarships are not very generous), we highly appreciate any financial support. We use every single donation to cover the mentioned expenses, and you can be sure that the more donations we receive the faster the development of Docear will progress. Therefore, every single Dollar/Euro matters, however small or large in sum.
