Privacy Policy
Last updated: March 12, 2026
This site is a personal blog, portfolio, and course platform operated by Chandler Nguyen. I collect as little data as possible. Here is what happens when you visit. By using this site, you acknowledge and accept the data practices described below.
What I Collect
Newsletter Subscription
If you subscribe to the newsletter, I collect your email address and your selected interest categories (e.g., AI, Expat Life, Leadership). This data is stored in Supabase (hosted in the US). I use it solely to send you relevant blog updates via Resend. Every email includes an unsubscribe link.
Course Accounts & Purchases
If you create an account to purchase a course, I collect your email address, name (if provided), and password (hashed, never stored in plain text). You may also sign in via Google or Apple, in which case I receive your email and display name from the provider. Purchase records (course purchased, amount, date, Stripe transaction ID) are stored in Supabase. Payment card details are handled entirely by Stripe and never touch my servers.
After purchase, you will receive a confirmation email via Resend with your access link and order details. These are transactional emails — not marketing.
Ask Sydney (AI Chat)
When you use the Ask Sydney feature, your questions are sent to the Anthropic API (Claude) to generate responses. Questions are not stored permanently — they exist only for the duration of your session. No account or login is required.
Analytics
I use Google Analytics 4 to understand which pages are visited and how people find the site. Google Analytics uses cookies to distinguish visitors. You can opt out using browser extensions like Google's own opt-out add-on or any ad blocker.
Bot Protection
The newsletter signup form and checkout pages use Cloudflare Turnstile to prevent spam and abuse. Turnstile may set a cookie to verify you are human. It does not track you across sites.
What I Do Not Collect
- No fingerprinting or cross-site tracking beyond Google Analytics
- No payment card numbers — all payment processing is handled by Stripe
Cookies
This site uses minimal cookies:
- Google Analytics — anonymous usage statistics
- Cloudflare Turnstile — bot protection on forms
- Theme preference — Theme preference — remembers dark/light mode (local storage, not a cookie)
- Auth session — session authentication for course accounts (HTTP-only, secure)

Data Retention & Deletion
Purchase records are retained as long as your account exists. To request deletion of your account and all associated data (including purchase history), email contact@chandlernguyen.com. Note that account deletion will revoke access to any purchased courses. Stripe may retain transaction records independently per their own privacy policy.

This policy may be updated at any time without notice. Continued use of the site constitutes acceptance of the current version.
