The general conditions of sale (GTC) are not imposed by law, but they are essential to properly manage a website or application. This agreement contains the rules for using your app or website and allows you to remove problematic users. The GTC become legally binding in the same way as a data protection declaration, as the documents are often presented together. Another important element of a binding agreement is that both parties intend that the agreement will have legal consequences. Each party to the contract must indicate that it acknowledges that it is legally bound to comply with the contract and that the agreement can be legally enforced. If the parties acknowledge that the agreement is legally binding, the contract is not obliged to expressly state this. On the other hand, if the parties do not want to be legally bound by the treaty, they must ensure that the treaty clearly expresses that wish. An infringement is made when one of the parties does not meet one or more of the conditions indicated. An infringement may also be found if certain work carried out is defective or shabby; or if a party has not performed the agreed work. This will then be put back in the hands of the law, where a judge will determine whether the contract has been breached and whether damages can be awarded to one of the parties.
