Breach of the EULA may lead to termination of the licence and closure of access. Deleting the Application does not by itself necessarily delete your account.

WIN may suspend, restrict or close your account in case of breach of this EULA or the Terms of Use, security risk, suspected abuse or legal requirements. In that case your licence ends.

When the licence ends, you must:
- immediately stop using the Application,
- remove the Application from your device,
- act in a way that does not infringe WIN’s rights in Platform Content.
