Terms Used

Per­son­al data” means any infor­ma­tion relat­ing to an iden­ti­fied or iden­ti­fi­able nat­ur­al per­son (here­inafter referred to as “data sub­ject”); an iden­ti­fi­able nat­ur­al per­son is one who can be iden­ti­fied, direct­ly or indi­rect­ly, in par­tic­u­lar by assign­ment to an iden­ti­fi­er such as a name, an iden­ti­fi­ca­tion num­ber, loca­tion data, an online iden­ti­fi­er (e.g. cook­ie) or to one or more spe­cial fea­tures that express the phys­i­cal, phys­i­o­log­i­cal, genet­ic, psy­cho­log­i­cal, eco­nom­ic, cul­tur­al or social iden­ti­ty of that nat­ur­al person.

Pro­cess­ing” means any oper­a­tion car­ried out with or with­out the aid of auto­mat­ed pro­ce­dures or any such series of oper­a­tions in con­nec­tion with per­son­al data. The term goes a long way and cov­ers prac­ti­cal­ly every han­dling of data.

Pseu­do­nymiza­tion” means the pro­cess­ing of per­son­al data in such a way that the per­son­al data can­not be attrib­uted to a spe­cif­ic data sub­ject with­out the use of addi­tion­al infor­ma­tion, pro­vid­ed that this addi­tion­al infor­ma­tion is kept sep­a­rate­ly and is sub­ject to tech­ni­cal and orga­ni­za­tion­al mea­sures that ensure that the per­son­al data are not attrib­uted to an iden­ti­fied or iden­ti­fi­able nat­ur­al person.

Pro­fil­ing” means any auto­mat­ed pro­cess­ing of per­son­al data con­sist­ing in the use of such per­son­al data to eval­u­ate cer­tain per­son­al aspects relat­ing to a nat­ur­al per­son, in par­tic­u­lar to analyse or pre­dict aspects relat­ing to the work per­for­mance, eco­nom­ic sit­u­a­tion, health, per­son­al pref­er­ences, inter­ests, reli­a­bil­i­ty, behav­iour, loca­tion or relo­ca­tion of that nat­ur­al person.

Respon­si­ble” means the nat­ur­al or legal per­son, author­i­ty, insti­tu­tion or oth­er body that alone or togeth­er with oth­ers decides on the pur­pos­es and means of pro­cess­ing per­son­al data.

Proces­sor” means a nat­ur­al or legal per­son, author­i­ty, insti­tu­tion or oth­er body pro­cess­ing per­son­al data on behalf of the data controller.

Applicable Legal Basis

In accor­dance with Art. 13 GDPR, we inform you of the legal basis of our data pro­cess­ing. If the legal basis is not men­tioned in the data pro­tec­tion dec­la­ra­tion, the fol­low­ing applies: The legal basis for obtain­ing con­sents is Art. 6 para. 1 lit. a and Art. 7 GDPR, the legal basis for pro­cess­ing for the ful­fill­ment of our ser­vices and imple­men­ta­tion of con­trac­tu­al mea­sures as well as for answer­ing inquiries is Art. 6 para. 1 lit. b GDPR, the legal basis for pro­cess­ing to ful­fill our legal oblig­a­tions is Art. 6 para. 1 lit. c GDPR, and the legal basis for pro­cess­ing to pro­tect our legit­i­mate inter­ests is Art. 6 para. 1 lit. f GDPR. In the event that the vital inter­ests of the data sub­ject or anoth­er nat­ur­al per­son require the pro­cess­ing of per­son­al data, Art. 6 para. 1 lit. d GDPR serves as the legal basis.

Security Measures

We take appro­pri­ate tech­ni­cal and orga­ni­za­tion­al mea­sures to ensure a lev­el of pro­tec­tion appro­pri­ate to the risk, tak­ing into account the state of the art, imple­men­ta­tion costs and the nature, scope, cir­cum­stances and pur­pos­es of pro­cess­ing as well as the dif­fer­ent prob­a­bil­i­ty of occur­rence and sever­i­ty of the risk to the rights and free­doms of nat­ur­al per­sons, in accor­dance with Art. 32 GDPR.

Such mea­sures shall in par­tic­u­lar include ensur­ing the con­fi­den­tial­i­ty, integri­ty and avail­abil­i­ty of data by con­trol­ling phys­i­cal access to the data, as well as its access, input, dis­clo­sure, ensur­ing avail­abil­i­ty and its sep­a­ra­tion. Fur­ther­more, we have estab­lished pro­ce­dures that guar­an­tee the exer­cise of data sub­ject rights, dele­tion of data and reac­tion to data risks. Fur­ther­more, we already con­sid­er the pro­tec­tion of per­son­al data dur­ing the devel­op­ment or selec­tion of hard­ware, soft­ware and pro­ce­dures, in accor­dance with the prin­ci­ple of data pro­tec­tion through tech­nol­o­gy design and data pro­tec­tion-friend­ly pre­set­tings (Art. 25 GDPR).

Cooperation with Contract Processors and Third Parties

If we dis­close data to oth­er per­sons and com­pa­nies (con­tract proces­sors or third par­ties) with­in the scope of our pro­cess­ing, trans­mit it to them or oth­er­wise grant them access to the data, this shall only take place on the basis of a legal per­mis­sion (e.g. if a trans­mis­sion of the data to third par­ties, such as pay­ment ser­vice providers, in accor­dance with Art. 6 Para. 1 lit. b GDPR for con­tract ful­fil­ment is nec­es­sary), if you have con­sent­ed, if a legal oblig­a­tion pro­vides for this or on the basis of our legit­i­mate inter­ests (e.g. when using agents, web hosts, etc.).

If we com­mis­sion third par­ties with the pro­cess­ing of data on the basis of a so-called “data pro­cess­ing agree­ment”, this is done on the basis of Art. 28 GDPR.

Transfers to Third Countries

If we process data in a third coun­try (i.e. out­side the Euro­pean Union (EU) or the Euro­pean Eco­nom­ic Area (EEA)) or if this occurs in the con­text of the use of third-par­ty ser­vices or dis­clo­sure or trans­fer of data to third par­ties, this only takes place in order to full­fil our (pre)contractual oblig­a­tions, on the basis of your con­sent, on the basis of a legal oblig­a­tion or on the basis of our legit­i­mate inter­ests. Sub­ject to legal or con­trac­tu­al per­mis­sions, we process or have the data processed in a third coun­try only if the spe­cial require­ments of Art. 44 ff. GDPR apply. This means, for exam­ple, pro­cess­ing is car­ried out on the basis of spe­cial guar­an­tees, such as the offi­cial­ly rec­og­nized deter­mi­na­tion of a data pro­tec­tion lev­el cor­re­spond­ing to the EU (e.g. for the USA by the “Pri­va­cy Shield”) or com­pli­ance with offi­cial­ly rec­og­nized spe­cial con­trac­tu­al oblig­a­tions (so-called “stan­dard con­trac­tu­al clauses”).

Rights of the Data Subjects

You have the right to request con­fir­ma­tion as to whether the data con­cerned are being processed and to request infor­ma­tion about these data as well as fur­ther infor­ma­tion and a copy of the data in accor­dance with Art. 15 GDPR.

In accor­dance with Art. 16 GDPR, you have the right to request the com­ple­tion of the data con­cern­ing you or the cor­rec­tion of inac­cu­rate data con­cern­ing you.

In accor­dance with Art. 17 GDPR, you have the right to demand that rel­e­vant data be delet­ed imme­di­ate­ly or, alter­na­tive­ly, to demand a restric­tion on the pro­cess­ing of the data in accor­dance with Art. 18 GDPR.

You have the right to request that the data con­cern­ing you that you have pro­vid­ed to us be received in accor­dance with Art. 20 DSGVO and to request its trans­mis­sion to oth­er per­sons responsible.

In accor­dance with Art. 77 GDPR, you also have the right to file a com­plaint with the com­pe­tent super­vi­so­ry authority.

Right of Revocation

You have the right to revoke con­sents grant­ed pur­suant to Art. 7 para. 3 GDPR with future effect

Right to Object

You can object to the future pro­cess­ing of the data con­cern­ing you in accor­dance with Art. 21 GDPR at any time. The objec­tion may be raised in par­tic­u­lar against pro­cess­ing for direct mar­ket­ing purposes.

Cookies and Right of Objection for Direct Mail

Cook­ies” are small files that are stored on the user’s com­put­er. Dif­fer­ent data can be stored with­in the cook­ies. A cook­ie is pri­mar­i­ly used to store infor­ma­tion about a user (or the device on which the cook­ie is stored) dur­ing or after his or her vis­it to an online offer. Tem­po­rary cook­ies, or “ses­sion cook­ies” or “tran­sient cook­ies”, are cook­ies that are delet­ed after a user leaves an online offer and clos­es his brows­er. In such a cook­ie, for exam­ple, the con­tent of a shop­ping bas­ket can be stored in an online shop or a login sta­tus. Cook­ies are referred to as “per­ma­nent” or “per­sis­tent” if they are stored even after the brows­er is closed. For exam­ple, the login sta­tus can be saved when users vis­it it after sev­er­al days. Like­wise, the inter­ests of users used for range mea­sure­ment or mar­ket­ing pur­pos­es may be stored in such a cook­ie. “Third-par­ty cook­ies” are cook­ies that are offered by providers oth­er than the per­son respon­si­ble for oper­at­ing the online offer (oth­er­wise, if they are only the cook­ies of the online offer, they are referred to as “first-par­ty cookies”).

We may use tem­po­rary and per­ma­nent cook­ies and clar­i­fy this with­in our pri­va­cy policy.

If users do not want cook­ies to be stored on their com­put­er, they are asked to deac­ti­vate the cor­re­spond­ing option in the sys­tem set­tings of their brows­er. Stored cook­ies can be delet­ed in the sys­tem set­tings of the brows­er. The exclu­sion of cook­ies can lead to func­tion­al restric­tions of this online offer.

A gen­er­al objec­tion to the use of cook­ies used for online mar­ket­ing pur­pos­es can be declared for a large num­ber of ser­vices, espe­cial­ly in the case of track­ing, via the US site or the EU site Fur­ther­more, the stor­age of cook­ies can be achieved by deac­ti­vat­ing them in the brows­er set­tings. Please note that in this case not all func­tions of this online offer can be used.

Deletion of Data

The data processed by us will be delet­ed or their pro­cess­ing restrict­ed in accor­dance with Arti­cles 17 and 18 DSGVO. Unless explic­it­ly stat­ed in this data pro­tec­tion dec­la­ra­tion, the data stored by us will be delet­ed as soon as it is no longer required for its intend­ed pur­pose and the dele­tion does not con­flict with any legal stor­age oblig­a­tions. If the data are not delet­ed because they are nec­es­sary for oth­er and legal­ly per­mis­si­ble pur­pos­es, their pro­cess­ing is restrict­ed. This means that the data is blocked and not processed for oth­er pur­pos­es. This applies, for exam­ple, to data that must be retained for com­mer­cial or tax reasons.

Accord­ing to legal require­ments in Ger­many, the stor­age is car­ried out in par­tic­u­lar for 10 years in accor­dance with §§ 147 para. 1 AO, 257 para. 1 no. 1 and 4, para. 4 HGB (books, records, man­age­ment reports, account­ing doc­u­ments, trad­ing books, doc­u­ments rel­e­vant for tax­a­tion, etc.) and 6 years in accor­dance with § 257 para. 1 no. 2 and 3, para. 4 HGB (com­mer­cial letters).

In accor­dance with legal require­ments in Aus­tria, stor­age is car­ried out in par­tic­u­lar for 7 years in accor­dance with § 132 (1) BAO (account­ing doc­u­ments, receipts/invoices, accounts, receipts, busi­ness papers, state­ment of income and expens­es, etc.), for 22 years in con­nec­tion with real estate and for 10 years for doc­u­ments in con­nec­tion with elec­tron­i­cal­ly pro­vid­ed ser­vices, telecom­mu­ni­ca­tions, radio and tele­vi­sion ser­vices which are pro­vid­ed to non-entre­pre­neurs in EU mem­ber states and for which the Mini-One-Stop-Shop (MOSS) is used.

Amazon Affiliate Program

We are, on the basis of our legit­i­mate inter­ests (i.e. inter­est in the eco­nom­ic oper­a­tion of our online offer with­in the mean­ing of Art. 6 para. 1 lit. f. DSGVO) Par­tic­i­pant of the Ama­zon EU part­ner pro­gram, which was designed to pro­vide a medi­um for web­sites through which adver­tis­ing and links to can earn reim­burse­ment of adver­tis­ing costs (so-called affil­i­ate sys­tem). Ama­zon uses cook­ies to trace the ori­gin of orders. Among oth­er things, Ama­zon can rec­og­nize that you clicked on the part­ner link on this web­site and then pur­chased a prod­uct from Amazon.

For fur­ther infor­ma­tion about Ama­zon’s use of data and pos­si­ble objec­tions, please refer to the com­pa­ny’s pri­va­cy pol­i­cy:>

Comments and Posts

If users leave com­ments or oth­er con­tri­bu­tions, their IP address­es may be used on the basis of our legit­i­mate inter­ests with­in the mean­ing of Art. 6 (1) (f). GDPR for 60 days. This takes place for our safe­ty, if some­one leaves ille­gal con­tents in com­ments and con­tri­bu­tions (insults, for­bid­den polit­i­cal pro­pa­gan­da, etc.). In this case we can be pros­e­cut­ed our­selves for the com­ment or con­tri­bu­tion and are there­fore inter­est­ed in the iden­ti­ty of the author.

Fur­ther­more, we reserve the right, on the basis of our legit­i­mate inter­ests pur­suant to Art. 6 para. 1 lit. f. GDPR to process user infor­ma­tion for spam detection.

The data pro­vid­ed in the con­text of com­ments and con­tri­bu­tions will be per­ma­nent­ly stored by us until the user objects.


With the fol­low­ing infor­ma­tion we inform you about the con­tents of our newslet­ter as well as the reg­is­tra­tion, dis­patch and sta­tis­ti­cal eval­u­a­tion pro­ce­dure and your rights of objec­tion. By sub­scrib­ing to our newslet­ter you agree to receive the newslet­ter and the described procedures.

Con­tent of the newslet­ter: We send newslet­ters, e‑mails and oth­er elec­tron­ic noti­fi­ca­tions con­tain­ing adver­tis­ing infor­ma­tion (here­inafter “newslet­ters”) only with the con­sent of the recip­i­ents or a legal per­mis­sion. If the con­tents of a newslet­ter are specif­i­cal­ly described with­in the scope of a reg­is­tra­tion, they are deci­sive for the con­sent of the users. In addi­tion, our newslet­ters con­tain infor­ma­tion about our ser­vices and us.

Dou­ble opt-in and log­ging: Sub­scrip­tion to our newslet­ter takes place in a so-called dou­ble opt-in pro­ce­dure. This means that after reg­is­tra­tion you will receive an e‑mail ask­ing you to con­firm your reg­is­tra­tion. This con­fir­ma­tion is nec­es­sary so that no one can log in with oth­er e‑mail address­es. Sub­scrip­tions to the newslet­ter are logged in order to be able to prove the reg­is­tra­tion process in accor­dance with legal require­ments. This includes the stor­age of the login and con­fir­ma­tion time, as well as the IP address. The changes to your data stored with the mail ser­vice provider are also logged.

Reg­is­tra­tion data: To sub­scribe to the newslet­ter, sim­ply enter your e‑mail address. Option­al­ly, we ask you to enter a name in the newslet­ter in order to address you personally.

The dis­tri­b­u­tion of the newslet­ter and the per­for­mance mea­sure­ment asso­ci­at­ed with it is based on the recip­i­en­t’s con­sent pur­suant to Art. 6 para. 1 lit. a, Art. 7 GDPR in con­junc­tion with § 7 para. 2 no. 3 UWG or on the basis of the legal per­mis­sion pur­suant to § 7 para. 3 UWG.

The reg­is­tra­tion pro­ce­dure is record­ed on the basis of our legit­i­mate inter­ests pur­suant to Art. 6 para. 1 lit. f GDPR. We are inter­est­ed in the use of a user-friend­ly and secure newslet­ter sys­tem that serves both our busi­ness inter­ests and the expec­ta­tions of users and also allows us to pro­vide proof of consent.

Cancellation/Revocation: You can can­cel the receipt of our newslet­ter at any time, i.e. revoke your con­sent. You will find a link to can­cel the newslet­ter at the end of each newslet­ter. We may store the e‑mail address­es we have unsub­scribed for up to three years on the basis of our legit­i­mate inter­ests before we delete them in order to be able to prove a pre­vi­ous­ly giv­en con­sent. The pro­cess­ing of these data is lim­it­ed to the pur­pose of a pos­si­ble defense against claims. An indi­vid­ual appli­ca­tion for can­cel­la­tion is pos­si­ble at any time, pro­vid­ed that at the same time the for­mer exis­tence of a con­sent is confirmed.

Newsletter — Mailchimp

Newslet­ters are sent by the mail ser­vice provider “MailChimp”, a newslet­ter mail­ing plat­form of the US provider Rock­et Sci­ence Group, LLC, 675 Ponce De Leon Ave NE #5000, Atlanta, GA 30308, USA. You can view the pri­va­cy pol­i­cy of the ship­ping ser­vice here: The Rock­et Sci­ence Group LLC d/b/a MailChimp is cer­ti­fied under the Pri­va­cy Shield Agree­ment and thus offers a guar­an­tee to com­ply with the Euro­pean data pro­tec­tion lev­el ( The mail ser­vice provider is employed on the basis of our legit­i­mate inter­ests pur­suant to Art. 6 para. 1 let­ter f DSGVO and an data pro­cess­ing agree­ment pur­suant to Art. 28 para. 3 sen­tence 1 DSGVO.

The mail ser­vice provider can use the recip­i­en­t’s data in pseu­do­ny­mous form, i.e. with­out assign­ment to a user, to opti­mize or improve its own ser­vices, e.g. to tech­ni­cal­ly opti­mize the dis­patch and lay­out of the newslet­ter or for sta­tis­ti­cal pur­pos­es. How­ev­er, the ship­ping ser­vice does not use the data of our newslet­ter recip­i­ents to con­tact them them­selves or to pass the data on to third parties.

Newsletter — Performance Measurement

The newslet­ters con­tain a so-called “web-bea­con”, i.e. a pix­el-sized file that is retrieved from our serv­er when the newslet­ter is opened or, if we use a mail ser­vice provider, from its serv­er. With­in the scope of this retrieval, tech­ni­cal infor­ma­tion, such as infor­ma­tion about the brows­er and your sys­tem, as well as your IP address and time of retrieval are ini­tial­ly collected.

This infor­ma­tion is used to tech­ni­cal­ly improve the ser­vices based on the tech­ni­cal data or the tar­get groups and their read­ing behav­iour based on their retrieval loca­tions (which can be deter­mined using the IP address) or access times. The sta­tis­ti­cal sur­veys also include deter­min­ing whether the newslet­ters are opened, when they are opened and which links are clicked. For tech­ni­cal rea­sons, this infor­ma­tion can be assigned to the indi­vid­ual newslet­ter recip­i­ents. How­ev­er, it is nei­ther our endeav­our, nor, if used, that of the ship­ping ser­vice provider, to observe indi­vid­ual users. The eval­u­a­tions serve us much more to rec­og­nize the read­ing habits of our users and to adapt our con­tents to them or to send dif­fer­ent con­tents accord­ing to the inter­ests of our users.


The host­ing ser­vices we use serve to pro­vide the fol­low­ing ser­vices: Infra­struc­ture and plat­form ser­vices, com­put­ing capac­i­ty, stor­age space and data­base ser­vices, secu­ri­ty ser­vices and tech­ni­cal main­te­nance ser­vices that we use for the pur­pose of oper­at­ing this online offer.

We or our host­ing provider process inven­to­ry data, con­tact data, con­tent data, con­tract data, usage data, meta- and com­mu­ni­ca­tion data of cus­tomers, inter­est­ed par­ties and vis­i­tors of this online offer on the basis of our legit­i­mate inter­ests in an effi­cient and secure pro­vi­sion of this online offer accord­ing to Art. 6 Para. 1 lit. f GDPR in con­junc­tion with. Art. 28 GDPR (con­clu­sion of data pro­cess­ing agreement).

Collection of Access Data and Log Files

We, or our host­ing provider, col­lect data on the basis of our legit­i­mate inter­ests with­in the mean­ing of Art. 6 para. 1 let­ter f. GDPR data on each access to the serv­er on which this ser­vice is locat­ed (so-called serv­er log files). Access data includes the name of the accessed web­site, file, date and time of access, trans­ferred data vol­ume, 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.

Log file infor­ma­tion is stored for a max­i­mum of 9 weeks for secu­ri­ty rea­sons (e.g. to inves­ti­gate mis­use or fraud) and then delet­ed. Data whose fur­ther stor­age is required for evi­den­tiary pur­pos­es are exclud­ed from dele­tion until the respec­tive inci­dent has been final­ly clarified.

Range Analysis with Matomo

In the scope of the range analy­sis of Mato­mo, on the basis of our legit­i­mate inter­ests (i.e. inter­est in the analy­sis, opti­miza­tion and eco­nom­ic oper­a­tion of our online offer with­in the mean­ing of Art. 6 para. 1 lit. f. GDPR) the fol­low­ing data are processed: the type of brows­er you use and the brows­er ver­sion, the oper­at­ing sys­tem you use, your coun­try of ori­gin, date and time of the serv­er request, the num­ber of vis­its, your time spent on the web­site and the exter­nal links you click. The IP address of the users is anonymized before it is stored.

Mato­mo uses cook­ies which are stored on the user’s com­put­er and which enable an analy­sis of the use of our online offer by the user. Pseu­do­ny­mous user pro­files can be cre­at­ed from the processed data. The cook­ies are stored for one week. The infor­ma­tion gen­er­at­ed by the cook­ie about your use of this web­site is only stored on our serv­er and not passed on to third parties.

Users can object to the anonymized data col­lec­tion by the Mato­mo pro­gram at any time with effect for the future by click­ing on the link below. In this case, a so-called opt-out cook­ie is stored in your brows­er, which means that Mato­mo no longer col­lects any ses­sion data. If users delete their cook­ies, how­ev­er, this means that the opt-out cook­ie is also delet­ed and must there­fore be acti­vat­ed again by the users.

Online Presences Within Social Media

We main­tain online pres­ences with­in social net­works and plat­forms to com­mu­ni­cate with active cus­tomers, prospects and users and to inform them about our ser­vices. When access­ing the respec­tive net­works and plat­forms, the terms and con­di­tions and the data pro­cess­ing guide­lines of their respec­tive oper­a­tors apply.span>

Unless oth­er­wise stat­ed in our pri­va­cy pol­i­cy, we process the data of users who com­mu­ni­cate with us with­in social net­works and plat­forms, e.g. write arti­cles on our web­sites or send us messages.

Integration of Third-Party Services and Content

We use with­in our online offer on the basis of our legit­i­mate inter­ests (i.e. inter­est in the analy­sis, opti­mi­sa­tion and eco­nom­ic oper­a­tion of our online offer with­in the mean­ing of Art. 6 para. 1 lit. f. GDPR) con­tent or ser­vice offer­ings of third par­ties, such as videos or fonts (here­inafter uni­form­ly referred to as “con­tent”).

This always pre­sup­pos­es that the third par­ty providers of this con­tent per­ceive the IP address of the users, since with­out the IP address they could not send the con­tent to their brows­er. The IP address is there­fore required for the dis­play of this con­tent. We make every effort to use only those con­tents whose respec­tive providers use the IP address only for the deliv­ery of the con­tents.
