Data Protection

We host the con­tent of our web­site with the fol­low­ing provider:

Microsoft Cor­po­ra­tion (Azure)

The provider is Microsoft Cor­po­ra­tion (Azure), One Microsoft Way, Red­mond, WA 98052–6399, USA (here­inafter referred to as Microsoft Azure). When you vis­it our web­site, Microsoft Azure col­lects var­i­ous log files includ­ing your IP address­es. For details, please refer to the Microsoft Azure pri­va­cy pol­i­cy: https://privacy.microsoft.com/de-de/privacystatement.

The use of Microsoft Azure is based on Art. 6 para. 1 lit. f GDPR. We have a legit­i­mate inter­est in ensur­ing that our web­site is pre­sent­ed as reli­ably as pos­si­ble. If a cor­re­spond­ing con­sent has been request­ed, the pro­cess­ing is car­ried out exclu­sive­ly on the basis of Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TTDSG, inso­far as the con­sent includes the stor­age of cook­ies or access to infor­ma­tion in the user’s ter­mi­nal device as defined by the TTDSG. The con­sent can be revoked at any time.

When you vis­it our web­site www.statmath.de, infor­ma­tion is auto­mat­i­cal­ly sent to the serv­er of our web­site by the brows­er used on your end device. This infor­ma­tion is tem­porar­i­ly stored in a so-called log file. The fol­low­ing infor­ma­tion is col­lect­ed with­out your inter­ven­tion and stored until auto­mat­ic dele­tion, usu­al­ly after one week:

• IP address of the request­ing com­put­er
• Date and time of access
• Name and URL of the file accessed
• Web­site from which access was made (refer­rer URL)
• Brows­er used and, if applic­a­ble, the oper­at­ing sys­tem of your com­put­er as well as the name of your access provider.

The afore­men­tioned data is processed by us for the fol­low­ing pur­pos­es:

• Ensur­ing a smooth con­nec­tion set­up of the web­site
• Ensur­ing a com­fort­able use of our web­site
• Eval­u­a­tion of sys­tem secu­ri­ty and sta­bil­i­ty
• Clar­i­fi­ca­tion of pos­si­ble abu­sive page access­es (DoS/DDoS attacks or sim­i­lar)
• For fur­ther admin­is­tra­tive pur­pos­es

The legal basis for data pro­cess­ing is Art. 6 para. 1 p. 1 lit. f GDPR. Our legit­i­mate inter­est fol­lows from the pur­pos­es for data col­lec­tion list­ed above. As a rule, we do not use the col­lect­ed data for the pur­pose of draw­ing con­clu­sions about your per­son. We reserve the right to do so at most in the event that this becomes nec­es­sary in order to clar­i­fy abu­sive page access­es. In addi­tion, we use cook­ies and analy­sis ser­vices when you vis­it our web­site (see Cook­ies and Analy­sis Tools).

For ques­tions of any kind, we offer you the oppor­tu­ni­ty to con­tact us via a form pro­vid­ed on the web­site.  In doing so, you are required to pro­vide a valid e‑mail address and your name so that we know who the enquiry is from and can answer it. Fur­ther infor­ma­tion can be pro­vid­ed vol­un­tar­i­ly.

Data pro­cess­ing for the pur­pose of con­tact­ing us is based on your vol­un­tar­i­ly giv­en con­sent in accor­dance with Art. 6 para. 1 p. 1 lit. a GDPR. The per­son­al data col­lect­ed by us for the use of the con­tact form will not be processed fur­ther after the request you have made has been dealt with. Fur­ther data pro­tec­tion infor­ma­tion for the use of the appli­ca­tion form can be found in the PDF doc­u­ment attached below: Data pro­tec­tion dec­la­ra­tion for appli­cants.

We offer our clients the pos­si­bil­i­ty to describe their coop­er­a­tion via a ref­er­ence ques­tion­naire. In doing so, it is nec­es­sary to pro­vide a valid e‑mail address as well as your name and a tele­phone num­ber so that we know who the ref­er­ence is from. The data pro­cess­ing for the pur­pose of con­tact­ing us is based on your vol­un­tar­i­ly giv­en con­sent in accor­dance with Art. 6 para. 1 p. 1 lit. a GDPR. The data of the ref­er­ence ques­tion­naire is stored until an objec­tion has been sub­mit­ted by the cus­tomer. Before a ref­er­ence is pub­lished, it is of course agreed with the client and only pub­lished after approval.

We do not trans­fer your per­son­al data to third par­ties for pur­pos­es oth­er than those list­ed below. We will only share your per­son­al data with third par­ties if:

• you have giv­en your express con­sent to this in accor­dance with Art. 6 Para.1 S. 1 lit. a GDPR
• the dis­clo­sure accord­ing to Art. 6 Para.1 S. 1 lit. f GDPR to assert
• exer­cise or defence of legal claims
• there is no rea­son to assume that you have an over­rid­ing inter­est wor­thy of pro­tec­tion in not dis­clos­ing your data
• in the event that there is a legal oblig­a­tion for the dis­clo­sure pur­suant to Art. 6 Para.1 S. 1 lit. c GDPR
• this is legal­ly per­mis­si­ble and nec­es­sary accord­ing to Art. 6 Para.1 S. 1 lit. b GDPR for the pro­cess­ing of con­trac­tu­al rela­tion­ships with you

We use cook­ies on our web­site. These are small files that are auto­mat­i­cal­ly cre­at­ed by your brows­er and stored on your end device (lap­top, tablet, smart­phone or sim­i­lar) when you vis­it our site. Infor­ma­tion is stored in the cook­ie that is relat­ed to the spe­cif­ic end device used.

How­ev­er, this does not mean that we gain direct knowl­edge of your iden­ti­ty. The use of cook­ies serves, on the one hand, to make the use of our offer more pleas­ant for you. We use so-called ses­sion cook­ies to recog­nise that you have already vis­it­ed indi­vid­ual pages of our web­site. These are auto­mat­i­cal­ly delet­ed after you leave our site.

In addi­tion, we also use tem­po­rary cook­ies to opti­mise user-friend­li­ness, which are stored on your end device for a cer­tain fixed peri­od of time. If you vis­it our site again to use our ser­vices, it is auto­mat­i­cal­ly recog­nised that you have already been to our site and which entries and set­tings you have made so that you do not have to enter them again.

On the oth­er hand, we use cook­ies to sta­tis­ti­cal­ly record the use of our web­site and to eval­u­ate it for the pur­pose of opti­mis­ing our offer for you (see Analy­sis tools). These cook­ies enable us to auto­mat­i­cal­ly recog­nise that you have already been to our web­site when you vis­it it again. These cook­ies are auto­mat­i­cal­ly delet­ed after a defined peri­od of time.

You can con­fig­ure your brows­er in such a way that no cook­ies are stored on your com­put­er or a mes­sage always appears before a new cook­ie is cre­at­ed.

How­ev­er, the com­plete deac­ti­va­tion of cook­ies may mean that you can­not use all the func­tions of our web­site.

Google Analytics 4

The web analy­sis ser­vice Google Ana­lyt­ics 4 is used on this web­site. The provider is Google LLC, whose respon­si­ble body for users in the EU, the EEA and Switzer­land is Google Ire­land Lim­it­ed, Google Build­ing Gor­don House, 4 Bar­row St, Dublin, D04 E5W5, Ire­land.

By using this tool, we are able to assign data, ses­sions and inter­ac­tions across mul­ti­ple devices to a pseu­do­ny­mous user ID and thus analyse the activ­i­ties of a user across devices.

Google Ana­lyt­ics uses ‘cook­ies’, which are text files placed on your com­put­er, to help the web­site analyse how users use the site. The infor­ma­tion gen­er­at­ed by the cook­ie about your use of this web­site is usu­al­ly trans­ferred to a Google serv­er in the USA and stored there.

In the Google Ana­lyt­ics 4 ver­sion, IP anonymi­sa­tion is always acti­vat­ed when using this web­site. This means that your IP address is trun­cat­ed with­in EU mem­ber states. Only in excep­tion­al cas­es will the full IP address be trans­mit­ted to a Google serv­er in the USA and trun­cat­ed there. Accord­ing to Google, the IP address is not merged with oth­er data.

When you vis­it our web­site, it is pos­si­ble that, for exam­ple, page views, the first vis­it to the page, the start of the ses­sion, the click path, scrolls to the end of the page, clicks on exter­nal links, inter­nal search queries, inter­ac­tion with videos, your approx­i­mate loca­tion, the IP address in abbre­vi­at­ed form, tech­ni­cal brows­er infor­ma­tion and your Inter­net provider are record­ed.

On behalf of the oper­a­tor of this web­site, Google will use this infor­ma­tion to analyse your use of the web­site and to com­pile reports on web­site activ­i­ty. We car­ry out these analy­ses with the aim of opti­mis­ing the per­for­mance of our web­site.

We use the User ID func­tion. With the help of the user ID, we can assign a unique, per­ma­nent ID to one or more ses­sions (and the activ­i­ties with­in these ses­sions) and analyse user behav­iour across devices].

This web­site uses the ‘demo­graph­ic char­ac­ter­is­tics’ func­tion of Google Ana­lyt­ics in order to be able to dis­play suit­able adverts to web­site vis­i­tors with­in the Google adver­tis­ing net­work. This allows reports to be gen­er­at­ed that con­tain state­ments about the age, gen­der and inter­ests of site vis­i­tors. This data comes from inter­est-based adver­tis­ing from Google and from vis­i­tor data from third-par­ty providers. This data can­not be assigned to a spe­cif­ic per­son. You can deac­ti­vate this func­tion at any time via the ad set­tings in your Google account or gen­er­al­ly pro­hib­it the col­lec­tion of your data by Google Ana­lyt­ics as described in the sec­tion ‘Objec­tion to data col­lec­tion’.

The legal basis for the pro­cess­ing of your data is your con­sent in accor­dance with Art. 6 para. 1 lit. a GDPR. Your con­sent can be revoked at any time for the future.

Your stored data will be auto­mat­i­cal­ly delet­ed after 2 months at the lat­est.

We have inte­grat­ed YouTube videos into our online offer, which are stored on http://www.YouTube.com and can be played direct­ly from our web­site. YouTube is anoth­er ser­vice pro­vid­ed by Google. YouTube videos are all embed­ded in “extend­ed data pro­tec­tion mode”, which means that no data about users is trans­mit­ted to YouTube if they do not play the videos. Only when a user plays the videos is the fol­low­ing data trans­ferred. We have no influ­ence on this data trans­mis­sion.

By vis­it­ing the web­site, YouTube receives the infor­ma­tion that the user has accessed the cor­re­spond­ing sub-page of our online offer when a video is played. In addi­tion, fur­ther infor­ma­tion about the use of this online offer (includ­ing the user’s IP address) is trans­mit­ted to a YouTube serv­er in the USA and stored there. This occurs regard­less of whether YouTube pro­vides a user account via which the user is logged in or whether no user account exists. If the user is logged in to YouTube, his or her data is direct­ly assigned to his or her account. If a user does not wish to have their data asso­ci­at­ed with their YouTube pro­file, they must log out before acti­vat­ing the but­ton. YouTube stores data as usage pro­files and uses them for the pur­pos­es of adver­tis­ing, mar­ket research and/or design­ing its web­site to meet users’ needs. Such an eval­u­a­tion is car­ried out in par­tic­u­lar (even for users who are not logged in) to pro­vide needs-based adver­tis­ing and to inform oth­er users of the social net­work about the user’s activ­i­ties on our online offer. The user has the right to object to the cre­ation of these user pro­files, and must con­tact YouTube to exer­cise this right.

Fur­ther infor­ma­tion on the pur­pose and scope of data col­lec­tion and pro­cess­ing by YouTube can be found in the pri­va­cy pol­i­cy, as well as fur­ther infor­ma­tion on rights and set­ting options for the pro­tec­tion of pri­va­cy:
