I am looking for good german <-> czech dictionary in text format (or something I can easy read).
The Idea behind is I would like to program a program for myself for learning czech, but the sources I found online are not good.

The dict.cc website has German (DE) to Czech (CS) translations, among many other languages to German or English.
They also offer a bulk download, with the following (abbreviated) terms:
Utilizing the data for personal use is granted provided that the data is not given away to third parties or published in any way.
and they mention software released must be GPL and that you can't reshare the data.
Anyway, the terms are friendly for your personal use, so you can fill out the email form and request your download link. You can choose either CS-to-DE or DE-to-CS, which is just the sorting.
