These services also depend on services provided by third parties, for whose continuation HMG does not assume any liability.

It allows the user to use the software free of charge for a one-time period of 14 days exclusively for test purposes. The corresponding usage relationship ends automatically upon expiration of 14 days after successful registration.

Single User license: This user license allows the user the licensed full access and gives the right to use the services via PGXperts as well as all updates during the respective term, according to these terms.

Within the scope of the registration all mandatory fields have to be filled out completely by the user. The e-mail address provided will be verified during registration process. Registration is only possible if the Terms and Conditions are accepted as legally binding.

3.2 After registration, the user will receive an e-mail to the e-mail address provided by him. A code is transmitted in the e-mail. By entering the code, the user legitimizes himself as the rightful owner of the specified e-mail address and completes the registration process by confirming it. Upon successful completion of the registration process, the user will be able to use the PGXperts services. This user relationship comes into effect upon completion of the registration and activation of the user account by HMG. A claim to activation and granting of the possibility of use and its availability does not exist.

3.4 The User confirms that he/she has provided truthful information during registration and that he/she will keep this information up to date and correct at all times. PGXperts reserves the right to verify the identity of the User, to unilaterally revoke the User’s authorization in the event of a serious breach of these Terms of Use and to block access to the PGXperts system. The user is liable for any misuse on his behalf or with his access data for which he is responsible.

This is to be assumed as a rule according to the fundamental orientation of the services.

Prior to completion of the order process on the PGXperts web portal, HMG will display the entries made by the User in a confirmation window and give the user the opportunity to check and, if necessary, correct his/her entries.

4.3 By confirming the “Buy” button, the User declares that he/she wishes to conclude a contract for the paid services selected by him/her. Confirmation of the “Buy” button merely constitutes an offer by the user to conclude a contract. This is binding for a period of 5 working days. HMG expressly reserves the right to accept or reject the User’s contractual offer within this period. There is no legal entitlement to the conclusion of the contract.

4.4 The acceptance of the offer by HMG and thus the conclusion of the contract arise upon receipt of the e-mail confirmation from PGXperts to the User.

In case of default payment, HMG reserves the right to make use of its right to refuse performance in accordance with the statutory provisions, for example to unilaterally revoke the user’s authorization to use PGXperts temporarily and to block access to PGXperts accordingly. The User is regularly obligated to pay in advance, unless otherwise agreed.

HMG shall be entitled to temporarily interrupt, limit or completely discontinue the Service, taking into account the respective legitimate interests of the parties. Services offered free of charge may be terminated or interrupted in whole or in part at any time at HMG’s sole discretion.

8.2 In the event of a foreseeable interruption or discontinuation of the Services, the user will be informed by HMG in due time by sending a notice to the e-mail address provided.
