We are not responsible for delay or failure caused by events outside our reasonable control, such as:
- Internet or telecommunications failures
- Power outages
- Provider outages
- Cyberattacks
- Government action

Our handling of personal information is described in the NorthStar Privacy Policy:
19. Changes to these terms
We may update these terms as NorthStar develops.
Where a change is material, we will provide reasonable notice through the service, by email or another appropriate method.
The latest terms will always be available at:
https://northstarlife.app/terms
Continuing to use NorthStar after updated terms take effect means the updated terms apply, except where the law requires a different form of agreement.
20. Governing law
These terms are governed by the laws of England and Wales.
If you are a consumer living elsewhere in the United Kingdom, you retain the benefit of any mandatory protections and may be entitled to bring proceedings in the courts of the part of the United Kingdom where you live.
21. General provisions
If part of these terms is found to be unlawful or unenforceable, the remaining provisions will continue to apply.
A delay in enforcing these terms does not waive the right to enforce them later.
You may not transfer your rights under these terms without our permission.
We may transfer our rights and obligations where this does not reduce your legal protections.
These terms, together with the Privacy Policy and any plan-specific terms, form the agreement between you and Coal Face AI Ltd concerning NorthStar.
