We will update the "Last Updated" date at the top of this page to reflect any changes.
These Terms shall be governed by and construed in accordance with the laws of Greece, without regard to its conflict of law provisions.
If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary so that these Terms shall otherwise remain in full force and effect.
