Privacy notice

When you request access, Constraint Alpha stores your email address, the time and version of your consent, verification status, and newsletter export status. A one-way, keyed summary of your IP address is retained for up to 30 days solely to prevent abuse; the raw address is not stored by the application.

Purpose: Your email is used to verify access and send the Constraint Alpha newsletter you consented to receive. Verified and consenting addresses may be transferred to Substack as the newsletter delivery provider. Supabase processes access records, Resend delivers verification emails, and Substack delivers newsletter messages.

Cookies: Constraint Alpha uses a strictly necessary first-party access cookie named __Host-ca_access to remember verified directory access on this device for up to 180 days. This cookie is HttpOnly, Secure, and SameSite=Lax, and is not used for advertising or cross-site tracking. Vercel Web Analytics may collect aggregate site usage data without cookies.

Your choices: You can unsubscribe using the link in any newsletter. To request access to or deletion of your stored information, contact Constraint Alpha through the reply/contact channel shown in the newsletter. Access records are retained while the directory and newsletter operate, unless deletion is requested or retention is no longer necessary.
