Privacy policy


This pri­va­cy pol­i­cy informs users about the nature, scope and pur­pose of the col­lec­tion and use of per­son­al data by the respon­si­ble provider Markus Wid­mer, Ble­icher­weg 33, 8002 Zurich, Switzer­land on this web­site (here­inafter referred to as “Offer”).

The legal basis for data pro­tec­tion can be found in the Fed­er­al Data Pro­tec­tion Act (BDSG) and the Tele­me­dia Act (TMG).

Access data/ Server log files

The provider (or his web space provider) col­lects data about each access to the offer (so-called serv­er log files). The access data includes:

Name of the accessed web­site, file, date and time of access, amount of data trans­ferred, noti­fi­ca­tion of suc­cess­ful access, brows­er type and ver­sion, the user’s oper­at­ing sys­tem, refer­rer URL (the pre­vi­ous­ly vis­it­ed page), IP address and the request­ing provider.

The provider uses the log data only for sta­tis­ti­cal analy­sis for the pur­pose of oper­a­tion, secu­ri­ty and opti­miza­tion of the offer. How­ev­er, the provider reserves the right to check the log data sub­se­quent­ly if there is a jus­ti­fied sus­pi­cion of unlaw­ful use based on con­crete indications.

Handling of personal data

Per­son­al data is infor­ma­tion that can be used to iden­ti­fy a per­son, i.e. infor­ma­tion that can be traced back to a per­son. This includes the name, email address or tele­phone num­ber. But also data about pref­er­ences, hob­bies, mem­ber­ships or which web­sites were viewed by some­one count as per­son­al data.

Per­son­al data is only col­lect­ed, used and passed on by the provider if this is per­mit­ted by law or the users con­sent to the data collection.


When con­tact­ing the provider (for exam­ple, by con­tact form or e‑mail), the user’s infor­ma­tion is stored for the pur­pose of pro­cess­ing the request and in the event that fol­low-up ques­tions arise.

Comments and contributions

When users leave com­ments on the blog or oth­er con­tri­bu­tions, their IP address­es are stored. This is done for the secu­ri­ty of the provider, in case some­one writes ille­gal con­tent in com­ments and posts (insults, pro­hib­it­ed polit­i­cal pro­pa­gan­da, etc.). In this case, the provider itself can be pros­e­cut­ed for the com­ment or post and is there­fore inter­est­ed in the iden­ti­ty of the author.

Comment subscriptions

Fol­low-up com­ments can be sub­scribed to by users. Users will receive a con­fir­ma­tion email to ver­i­fy that they are the own­er of the email address entered. Users may unsub­scribe from ongo­ing com­ment sub­scrip­tions at any time. The con­fir­ma­tion email will include instruc­tions on how to do so.


With the newslet­ter we inform you about us and our offers.

If you would like to receive the newslet­ter, we require a valid email address from you as well as infor­ma­tion that allows us to ver­i­fy that you are the own­er of the spec­i­fied email address or that the own­er agrees to receive the newslet­ter. Fur­ther data will not be col­lect­ed. This data is only used for send­ing the newslet­ter and will not be passed on to third parties.

With the reg­is­tra­tion for the newslet­ter, we store your IP address and the date of reg­is­tra­tion. This stor­age serves sole­ly as proof in the event that a third par­ty mis­us­es an email address and reg­is­ters to receive the newslet­ter with­out the knowl­edge of the autho­rized person.

You can revoke your con­sent to the stor­age of data, the email address and its use for send­ing the newslet­ter at any time. The revo­ca­tion can be made via a link in the newslet­ters them­selves, in your pro­file area or by send­ing a mes­sage to the con­tact options above.

Integration of third-party services and content

It may hap­pen that third-par­ty con­tent, such as videos from YouTube, RSS feeds or graph­ics from oth­er web­sites, are inte­grat­ed with­in this online offer. This always requires that the providers of this con­tent (here­inafter referred to as “third-par­ty providers”) per­ceive the IP address of the user. With­out the IP address, they could not send the con­tent to the brows­er of the respec­tive user. The IP address is thus nec­es­sary for the dis­play of this con­tent. We endeav­or to use only such con­tent whose respec­tive providers use the IP address only for the deliv­ery of the con­tent. How­ev­er, we have no influ­ence if the third-par­ty providers store the IP address, e.g. for sta­tis­ti­cal pur­pos­es. Inso­far as this is known to us, we inform the users about it.


Cook­ies are small files that enable spe­cif­ic infor­ma­tion relat­ed to the device to be stored on the user’s access device (PC, smart­phone or sim­i­lar). On the one hand, they serve the user-friend­li­ness of web­sites and thus the nu
