This site uses Umami, an audience measurement tool hosted in the European Union, with no cookies and no collection of identifiable personal data.

No full IP address is retained, and no individual profiling is performed.

Transfer to third-party services

The main call-to-action button redirects to a shortened Bitly link, which then redirects to Calendly for booking.
