When you visit
Cloudflare hosts and protects this website. It processes technical information, including your IP address and request information, to deliver pages, operate its network, and prevent abuse. Operational logs may be used to investigate errors and security issues. The contact form also uses Cloudflare to limit repeated submissions based on your IP address.
When you get in touch
The contact form collects your name, email address, and message. Resend delivers these details by email to Stern Advisory. They are used to respond to your inquiry and discuss any work you request. Sending a message does not subscribe you to a mailing list.
Correspondence is kept as needed to handle your inquiry and any resulting business relationship, and to meet applicable record-keeping obligations. Please include only information relevant to your inquiry.

Analytics and cookies
