Analytics

This site uses privacy-friendly, cookieless analytics (Vercel Web Analytics) to understand aggregate traffic — which pages are read and which links are followed. It sets no cookies, does not track you across sites, and does not build a profile of you. No consent banner is required because no personal data is stored on your device.

This data is aggregate and used only to improve the site.

The SHeine Brief Newsletter

The newsletter is published on Substack. When you subscribe — whether from this site or on Substack directly — your email address and subscription are handled by Substack, Inc. as the data processor, under Substack's privacy policy. You can unsubscribe from any issue at any time.

Advisory Enquiries

The enquiry and contact buttons open your own email client with a pre-filled message addressed to sebastian@sheine.ai. Nothing is sent unless you choose to send it. Any details you include reach Sebastian directly by email and are used only to respond to your enquiry.

Hosting

The site is hosted on Vercel. Like most web hosts, Vercel processes standard server request data (such as IP address and user agent) to serve pages and protect against abuse.

Your Rights

Depending on where you live, you may have the right to access, correct, or delete personal data held about you, and to object to certain processing. For anything held by Sebastian directly (for example, an email enquiry), contact sebastian@sheine.ai. For data held by Substack or Google, please use their respective privacy controls.

Changes

This page may be updated as the site changes. If new processing is added — additional analytics, a server-side form, or account features — this page will be updated to reflect it.
