Nothing to say here. I just own all the data you give to me, and I could never provide any proof that I am not doing anything bad with them. Please, do not give them if you do not want me to know them.
Speaking of cookies, it is entirely your choice to tell your computer to save or not the cookies I propose to it.
One of my goals with this server is, however, to enable people to improve their privacy on the Web, so a priori I will not share your data, and under no circumstances I will share them for trading or advertisement without your prerequisite agreement. In general, they are only stored during the time they are needed for their normal use, as well as residually in temporary logs for statistics (totally anonymous) and maintenance. No user tracking system is set.
The server runs quasi-exclusively on libre softwares, generally designed to respect users' privacy.
