7. Enforcement

We reserve the right to:

Investigate any suspected violation of this AUP;
Suspend or terminate your licence, including without notice where reasonably necessary, for violations;
Report violations to law enforcement authorities where appropriate;
Take any other action we deem necessary to enforce this AUP.

A refund will not normally be provided if your licence is terminated for a serious violation of this AUP. This does not affect your statutory rights.

8. Monitoring

Your records are stored on your own devices and we have no access to them, so we do not and cannot monitor their content. We may monitor use of our licensing service (for example, device registrations) to detect misuse and enforce this policy.

9. Changes to This Policy

We may update this AUP. Changes will be posted on this page, and material changes will be notified as described in the Terms of Service.
