6Service Continuity Disclaimer
The access rights (license) granted to you under these Terms are contingent upon the Operator's continued provision of the Service. We do not guarantee uninterrupted or indefinite availability of the Service.
The Operator may suspend or discontinue all or part of the Service, with prior notice where reasonably practicable, or without prior notice in urgent circumstances, in any of the following situations:
- Technical or Operational Reasons System failures, changes or discontinuation of third-party services (such as payment processors or hosting providers), or other technical or business circumstances that make continued operation impracticable.
- Force Majeure Natural disasters, changes in applicable laws or regulations, governmental orders, or other events beyond the Operator's reasonable control.
- Other Reasons Any other circumstances analogous to the above in which the Operator reasonably determines that suspension or termination is necessary.
In the event of service suspension or termination, refunds for unused subscription periods will generally not be issued, except where the termination results from the Operator's willful misconduct or gross negligence, in which case we will respond on an individual basis.
This article is intended to transparently communicate risks inherent to all digital services. The Operator is committed to maintaining stable, continuous service, but we ask that you acknowledge these possibilities before subscribing.
