What we use

·Necessary: short lived technical cookies that keep the site working and protect it from abuse. These cannot be switched off.
·Measurement: anonymous, aggregated statistics on which pages are read, set only if you accept them.
·Booking: when you open the scheduling form, our scheduling provider sets its own cookies so it can hold your selection.

We set no advertising cookies and build no cross site profiles.

Your control

Measurement stays off until you accept it. You can clear or block cookies in your browser settings at any time. Blocking necessary cookies may break parts of the site, including the booking form.

Third party embeds

The booking calendar on the home page is loaded from our scheduling provider. Opening it means your request reaches that provider, which handles the data under its own terms.
