They do not create any rights for third parties. If you do not comply with these terms and we do not take immediate action, this does not mean that we are waiving any rights that we may have (such as taking future actions). If a specific condition of these terms is not enforceable, this will not affect any other terms.
VIOLATIONS OF THE TERMS OF USE
The USER may only access the products and services for lawful purposes. The USER is fully responsible for knowledge and adherence to any and all laws, regulations and rules pertinent to the use of the products and services covered by this term. If the contractual termination occurs due to non-compliance or violation by the USER of the provisions of this term, as well as non-compliance or violation of applicable legislation, no refund of amounts already paid will be due.
The USER may not reproduce, distribute, transmit, display, sell, license, alienate in any way or exploit any content accessed on D-Fit for any purposes, onerous or not.
