We will start off with an english version. This means that all the copy within the interface will be in the system language: Menus, buttons and info texts. Also the autocomplete recommendations are only available within the system language.
However we are already working on a german version and also have other languages in mind. Please tell us your needs here.
Obviously all the informations you are cataloging can already be within your native language: Mineral species, localities, text descriptions and notes and anything else. Unfortunately if you enter mineral names which are not in our english database you will not receive associated informations like the chemical formula.
