There's a thread on this magazine but it's in the genre forum.
Currently they have a science fiction contest. They claim ownership of all submissions. Bolding mine:
Non-exclusive rights forever is bad enough for accepted material, and I would never submit to such a thing. But grabbing rights on submissions is a truly crappy deal for writers.The entries submitted to this contest will become the property of Kalkion. The copyright to the entries will return to respective author only after the completion of the contest and under the condition that Kalkion will retain non-exclusive, unlimited rights over the entries.
Kalkion reserves all the rights to re-produce the submitted work in any form, format and medium (known and unknown today). Kalkion will try to inform the concerned author about the re-produced work, but it it is not mandatory.
