  2. The user is not permitted to change, adapt, translate, create derivative works from, reverse engineer, disassemble, or decompile the App or otherwise attempt to derive the source code of the App. Legal powers remain unaffected, especially the right of the user to decompile the App to obtain the necessary information to establish its interoperability with other programs, unless Refinca makes it available to him on reasonable terms. The user is not allowed to decompile the App for other purposes.
  3. In addition, any use of the App that has a negative impact on the App itself or on websites connected to it, or on software accessed through the App is prohibited.

If no specific term has been agreed on, the license agreement can be terminated at any time with a notice period of three months without having to give any reasons.

In the case of an App subscription, the user also has the option of preventing the license agreement from being renewed for a new subscription period by clicking on the cancellation button integrated in the App; however, this must be done at least 24 hours before the new subscription period begins. Otherwise, the license agreement will be extended by the agreed new subscription period.

    Insofar as the liability is not in accordance with the above list governed by the statutory provisions, the following applies: In cases of slightly negligent violation of only insignificant contractual obligations Refinca is not liable for damages. Otherwise, liability for damages caused by slight negligence shall be limited to those damages that are typically to be expected within the scope of the respective contractual relationship (typically foreseeable damages).
  2. Insofar as the liability of Refinca is excluded or limited according to these provisions, this shall also apply to the liability of Refinca’s organs, vicarious agents, and assistants, including the employees.
  3. If Refinca is held liable by a third party due to a violation of these conditions of use by the user, the user indemnifies Refinca against all claims and costs arising directly or indirectly from this, including reasonable costs for defense by a lawyer. This does not apply insofar as the user is not responsible for the violation.
