What I collect

When you use the contact form, I get what you type: the name you want me to use, your email address, your message, and that you confirmed you're 18 or older. Nothing else is collected on this site. There are no ads and no tracking cookies.

What I use it for

Only to read your message and reply to you, and, if it's a fit, to send you an intake form. I don't sell or share it, and I don't add you to a mailing list.

Where it's stored

• Your message is saved in a private database (Supabase) that only I can read.
• A copy is emailed to me so I can reply.
• The site runs on Cloudflare, which processes requests to serve the page.
• The contact form uses Cloudflare Turnstile to check that you're a person, which looks at some signals from your browser. It doesn't use cookies for tracking.

Deleting it

Email contact@sfwmath.com and I'll delete everything you sent.

Students

If you join the program, a separate consent form explains exactly how session recordings, transcripts and other materials are handled before anything is recorded.
