represented by its managing directors Benedikt Hochkirchen, Dr. med. Madjid Salimi, Dr. med. Nawid Salimi, registered in the Commercial Register of the Local Court of Berlin (Charlottenburg) under HRB 209607 (hereinafter: "AMBOSS GmbH") and the respective authorized user, who makes use of information and services on the Internet portal including all sub-pages, insofar as the use of the same requires registration of the authorized user (hereinafter: "authorized user") (hereinafter: "services"). 

If special conditions for individual uses of the services offered via deviate from the following Terms of Use, this will be indicated at the appropriate place within the website. In the respective individual case, the special Terms of Use shall then apply additionally.

1.2. AMBOSS GmbH is the rights holder, provider and operator of the online knowledge and learning program "AMBOSS" (hereinafter: "AMBOSS"), which it has developed and which it makes available on the internet platform, in particular to doctors, medical students and others working in the healthcare sector. All information provided on AMBOSS refers to the medical standard in the United States, i.e. the standards stated, e.g. on diagnostic and/or therapeutic procedures, may differ in other countries. Similarly, all information provided on AMBOSS regarding the use of certain commercial medicinal products relates to the regulatory approval status of the respective medicinal product in the United States. In other countries, the respective approval status may differ.

1.3. The professional editorial team of AMBOSS consists of a large number of medical professionals with different levels of experience and from different medical specialties. With high frequency, new and/or updated content is added to the AMBOSS database by this editorial team in a structured, collaborative process and thus made available to authorized users. All content is subject to a multi-stage internal peer review process, which checks all publications for scientific up-to-dateness, consistency and comprehensibility. Although this process is carried out with reasonable care, the AMBOSS database – simply because of the abundance of new medical information – cannot contain a comprehensive, up-to-date representation of all medical information.

1.4. The information contained in AMBOSS does not constitute binding diagnostic, treatment and therapy suggestions. Diagnostic, treatment and therapy decisions as well as other patient care decisions derived from the use of AMBOSS are the sole responsibility of the respective user. The use of AMBOSS does not release users from their obligation to make decisions on their own responsibility on the basis of the current state of science and research. In this respect, the information contained in AMBOSS must be reviewed in relation to each specific individual case, taking into account the individual patient characteristics. 

1.5. If users display a translation of AMBOSS content within the platform in a language other than the English-language version of the AMBOSS content, they will display an automated translation using the API of DeepL. The translated content is not part of the AMBOSS knowledge and learning program. AMBOSS itself does not carry out the translation and cannot check the translated content. In particular, AMBOSS does not carry out any medical review. The machine-translated content does not fulfil the due diligence and quality standards of AMBOSS. Translation errors cannot be expressly excluded. The machine-translated content does not replace a translation by a linguistically competent specialist, which is recommended.

1.6. The following Terms of Use apply to the use of the AMBOSS GmbH Internet platform including AMBOSS.

1.7. Some of the content made available at can only be accessed after registration. In addition to various other free services, AMBOSS GmbH offers registered users services for a fee, in particular a medical knowledge network and learning access to fictitious examination papers.

1.8. AMBOSS GmbH shall provide the aforementioned services exclusively on the basis of these Terms of Use. Deviating terms and conditions shall not be recognized unless there is express written confirmation from AMBOSS GmbH.

The following Terms of Use are subdivided as follows:

Part A: General Regulations for all Authorized Users of the Services Requiring Registration

2.2. AMBOSS GmbH shall provide authorized users with access to the English-language AMBOSS platform and its content via the Internet in accordance with the respective user agreement concluded, including these Terms of Use.

3. Registration/Conclusion of contract

3.1.

This does not initially establish a separate contractual relationship between AMBOSS GmbH and the authorized user.

In this case, the Special Regulations for Authorized Users of the Fee-Based Services in Part B of these Terms of Use shall apply additionally. In the case of user agreements between individuals and AMBOSS GmbH concerning the use of AMBOSS, the individuals are authorized users and at the same time contractual partners within the meaning of these Terms of Use. The Special Regulations for Authorized Users of Fee-Based Services in Part B as well as individual contractual agreements between the individuals and AMBOSS GmbH shall take precedence over these General Regulations for all Authorized Users of the Services Requiring Registration in case of doubt.

3.4. AMBOSS GmbH shall allocate personal authorized user accounts to the authorized users. The authorized user accounts can be used by the authorized users during the term of the user agreement existing with the contractual partner.

By completing the registration process, the authorized user makes an offer to conclude a contract on the use of AMBOSS on the basis of these Terms of Use. AMBOSS GmbH accepts this offer by activating the authorized user's account. This acceptance creates a free contractual relationship between the authorized user and AMBOSS GmbH. 

3.6. The e-mail address of the authorized user will be verified during or after registration, if necessary.

3.7. The authorized user warrants that all data provided by him/her for registration is correct and complete. Furthermore, the authorized user is obliged to keep his or her data up to date at all times.

3.8. The choice of a password is required for registration. The confidentiality of the password as well as all activities carried out under his/her account are the sole responsibility of the authorized user. Passing on the password is not permitted.

3.10. The authorized user can request the deletion of his/her registration at any time in writing or via the corresponding function on AMBOSS. In this case, AMBOSS GmbH will delete all authorized user data and all other stored personal data of the authorized user as soon as these are no longer required.

The authorized user is not authorized to use AMBOSS and the AMBOSS contents commercially in any form, for example by offering AMBOSS and the AMBOSS contents as a service to third parties. Copyright notices and brand names may neither be changed nor removed.

4.4. Program or database access to persons who do not belong to the group of persons defined in sec. 3.2 is not permitted.

In the event of such a blocking AMBOSS GmbH may provide an alternative access at the request of the contractual partner.

4.5. The usage authorization expires irrespective of the term of the user agreement concluded with the contractual partner if the circumstance leading to the usage authorization (cf. sec. 3.1 and 3.2) ceases to apply, i.e. in the case of students due to de-registration of the student, in the case of teaching staff due to termination of their teaching activities with the contractual partner, in the case of doctors or other clinical staff due to termination of their employment relationship with the contractual partner. In this case, the authorized user can acquire a personal authorization to use AMBOSS.

4.6. Within the scope of the initial registration of the authorized user, the present Terms of Use as well as the data protection information can be viewed and archived.

4.7. AMBOSS GmbH reserves the right to use all contents of this website for text and data mining.

6. Copyright

The authorized user is obliged to observe the existing copyrights and undertakes not to infringe them. The authorized user may only retrieve, store and use the content for his/her own use for learning or training purposes. 

7. Obligations of AMBOSS GmbH / Availability

7.1. AMBOSS GmbH is obliged vis-à-vis the contractual partner, but not vis-à-vis the authorized user, to make AMBOSS available and accessible for use via the Internet. AMBOSS shall be stored on a server in such a way that it can be accessed by the authorized users via the Internet.

7.2. AMBOSS GmbH shall endeavor to achieve availability of AMBOSS around the clock. AMBOSS GmbH provides AMBOSS with an availability of at least 99.1 % based on the calendar year. This percentage refers to the period outside planned non-availabilities.

Such restrictions shall not be taken into account when determining availability in accordance with this sec. 8.2.

7.3. Update and maintenance work may be carried out daily between 03:00am and 05:00am German time. During this time, AMBOSS may be temporarily unavailable or only available to a limited extent.

8. Warranty, reduction of the remuneration

8.1. In the event of a failure of the system outside of planned non-availabilities or in the event of defects occurring which considerably restrict the possibility of using AMBOSS, the contractual partner, but not the authorized user, is entitled to reduce or reclaim the remuneration – on a pro rata basis of 1/12 of the annual license fees – for the calendar month in which the failure occurred in accordance with the following conditions:

In the event of a failure of more than

a. 6.5 hours per calendar month: 5% reduction

b. 15 hours per calendar month: 12.5 % reduction

c. 24 hours per calendar month: 25% reduction

d. 48 hours per calendar month: 50% reduction

e. 72 hours per calendar month: 100 % reduction

of 1/12 (one twelfth) of the annual license fees according to the user agreement.

8.2. With each month of running time in which there is no reduction, the sum of 6.5 hours minus the downtime that actually occurred is credited as downtime credit. If downtimes occur later, these times are first deducted from the total downtime credit, i.e. the aforementioned percentage reduction only occurs if there is no sufficient downtime credit for the downtimes that occurred in the month.

8.3. The contractual partner may request the reduction as a refund or assert it by offsetting it against a subsequent annual license.

8.4. A warranty or reduction according to this sec. 9 is excluded for failures or disruptions due to force majeure (e.g. measures in the context of industrial disputes, strikes or lockouts, pandemics).

8.5. In all other respects, liability shall be governed by the limitations set forth in sec. 12 of these Terms of Use.

In doing so, it is possible to make various information (e.g. name, institution, department, field of specialisation, etc.) available and findable for other users and to network with other users. The user can activate or deactivate this service in his/her user profile by making in the appropriate settings all or individual data and information available and findable to all or, if applicable, to only certain users.

9.2. If the user wishes to network with another user on AMBOSS, he/she can submit a contact request on AMBOSS, which will be sent to the requested user in his/her user profile and/or by e-mail by AMBOSS. The requested user has the option of accepting or rejecting the request.

a. for damages resulting from injury to life, limb or health,

b. for damages arising from the breach of an essential contractual obligation (an obligation whose fulfillment is essential for the proper execution of the contract and on whose compliance the contractual partner regularly relies and may rely); in this case, however, the liability of AMBOSS GmbH is limited to compensation for foreseeable, typically occurring damages.

11.5 The aforementioned limitations of liability also apply to third parties and in the event of breaches of duty by persons (including in their favor) whose fault AMBOSS GmbH is responsible for in accordance with statutory provisions.

12.1. These Terms of Use and the contractual relationship arising from the user agreement between AMBOSS GmbH on the one hand and the contractual partner and the authorized user on the other hand shall be governed by the law of the Federal Republic of Germany to the exclusion of international uniform law, in particular the UN Convention on Contracts for the International Sale of Goods.
