Privacy

What I collect

• When you subscribe: your email, which form you used, the page you landed on, the site that sent you, any utm tags in the link, and your country (from Cloudflare, not your IP address). This tells me which posts bring readers. The newsletter itself is sent by Substack under its own privacy policy.
• When you send a message: your name, email, company if you give it, and the message.
• When you share a result: what you write in the form, and your consent to publish it. Your email, if you give one, is never shown.
• Analytics: Cloudflare Web Analytics counts page views without cookies and without tracking you across sites.

Where it lives

In a Cloudflare D1 database. Cloudflare also runs Turnstile, the spam check on the forms. Contact-form emails are sent through Resend. Nothing is sold, and there are no advertising cookies.

Deleting it

Email hao.hoang@aiengineerlabs.us and I'll delete your records from this site's database. To stop the newsletter, use the unsubscribe link in any issue.
