This site leaves you alone.

No cookies. No third-party trackers, no ad pixels, no fingerprinting, nothing that follows you to another site. What I do keep is a plain count of visits: which page was opened, where the link came from, a coarse country, and any campaign tag on the address. Each visit carries a one-way marker that is rebuilt from scratch every day, so it cannot be traced to you or joined up across days. Your IP address and browser details are never stored; the marker is derived from them and cannot be turned back into them. These records are deleted after 12 months.

3 technical notes, in plain terms. If you switch between light and dark, that preference is stored in your own browser and never leaves it; clear your browser data and it is gone. If you arrive from a tagged link, the tag is remembered in your own browser for 30 days, so that a booking you go on to make can be credited to the place you came from. The calculator runs entirely in your browser too, so the numbers you enter never leave the page.

The site is hosted by Netlify, which keeps standard server logs (IP address, time, page requested) to run its service; those are governed by Netlify’s privacy policy. Every contact link on this site opens your own mail app. If you write to me, your email stays between us: no list, no sequence, no sharing.

Booking a call at /call is the one place this site asks you for anything: your name and email, to schedule and confirm the session, and anything you add in the notes field. That booking system is mine, the same one behind eugenesiew.com, not a third-party scheduler, and Resend sends the confirmation email on my behalf. Zoom creates the meeting for the call, where your name appears in the meeting title, and the booking record itself is stored in Supabase, the database behind that system. Nothing else here asks you for anything, and if that ever changes, this page will say so before it happens.

The visit counting described above is the same first-party system that runs on eugenesiew.com, and the 2 sites share 1 record of it. I read it to see which pages get read and which links bring people here.
