The only place the Site collects personal information is the contact form.

The Site does not use cookies. It carries no analytics tools and no advertising tags.

We use it for nothing else. We will not add you to marketing or promotional sends without your consent.
- Responding to your inquiry and any correspondence needed to do so
- Recording your inquiry and sharing it internally
- Blocking spam and investigating faults
4. Sharing with third parties
We do not share your personal information with third parties, except with your consent or where disclosure is required by law.

We use the following providers to run the Site and handle inquiries. Each processes information under our instruction and only for the purposes in section 3.
