12. MISCELLANEOUS

If any provision is held unenforceable, the remainder remains in effect. This EULA and any applicable store terms are the full agreement between you and Company. Failure to enforce any term is not a waiver of that term. We are not liable for events beyond our control. Sections related to warranties, liability, arbitration, and export controls survive termination.
