GDPR Compliance Information
Owner, responsible contact: Norbert Landsteiner

This site doesn’t collect, track, or process any user data, other than standard server access logging.

No user data is traded to third parties or shared otherwise.
(A few games may set a cookie to store high-scores locally. These cookies are used to store state on the client side only and are not processed or logged on the server side. These games predate other local storage technologies, available today, and probably won’t be rewritten just for this.)

However, a few pages may embed 3rd party resources hosted by services by Google, Inc., namely Google Web Fonts and Google Adsense (ad-per­sonali­zation set to off). A few project related pages also embed videos hosted by YouTube using a type of embedding which should not be tracking users before they actively start a video (via www.youtube-nocookie.com). Please mind that these 3rd parties may log or process user data on their own end (respective to user settings). Compare Google Privacy / GDPR Compliance.

By clicking any of the “Share” buttons, found on a few pages, resources from related social media services like Facebook, Twitter, Google+ will be embedded. (None of these resources are loaded without this interaction, which will be interpreted as a user consent.) Again, any GDPR compliance regarding these resources is subject to the policies employed by the respective 3rd parties and beyond the realms of this website.

This site has opted out of the controversial Google FLoC network by setting appropriate HTTP-headers. (FLoC, an interest-based advertising technology, is supported by Google Chrome only.)



“mass:werk – media environments” and “masswerk.at” are names associated to the work and services of the individual enterprise (sole proprietorship) of Norbert Landsteiner.

In April 1999 masswerk.at started to publish works in the domains of visual design and internet applications under the then unique name “mass:werk”. Meanwhile, various unrelated parties in German speaking countries (namely in the fields of architectural design and interior design) have chosen to adopt the same name in slightly derivative spelling. We apologize for our fellow competitors’ lack of creativity and finite sense for identity.
Similar applies to various “masswerk” internet domains (be it top level or second level domains) that have flourished since. Please mind that only <masswerk.at> points to the original ‘mass:werk – media environments’ site.
