qlstats.net is operated by a private person residing in Austria, so the Austrian Datenschutzgesetz 2000 (data privacy law) is applicable.
The relevant parts of the the DSG 2000, which implements EU Directive 95/46/EG in national Austrian law, are:
§ 4 Z 1, § 8 Abs. 2, § 12 Abs. 3 Z 2, § 17 Abs. 2 Z 3, § 29
Note that the law makes explicit distinctions between directly and indirectly identifiable data.
I do NOT store any information which could be used to directly identify a person (e.g.: name, home address, email address, ip-address, ...)
The stored information is tied to a steam-id, which only indirectly identifies a person and cannot be used to retrieve a person's identity, neither by qlstats.net nor a 3rd party receiving data from qlstats.net.
qlstats.net is not responsible for user generated content (i.e. a users nicknames) nor for content on linked external sites (i.e. steam profiles). If unlawful or offending content is found and/or reported to qlstats, it will be removed as soon as possible.
