This Privacy Policy explains how Li Xiaolai (“I”, “me”, “my”) collects, uses, and protects your information when you use lixiaolai.com (the “Site”). By using the Site, you agree to the practices described below.

1. Information I Collect

Account Information

When you create an account, I collect your name and email address. If you sign in through a third-party provider (GitHub or Google), I receive your provider user ID and associated profile information (such as display name and email) as authorized by that provider.

Purchase Information

When you purchase courses or other content, payment is processed by Stripe. I store your Stripe customer ID and a record of your purchases (items, dates, and amounts). I do not store your credit card number or full payment details — those are held exclusively by Stripe.

Automatically Collected Information

Like most websites, the Site automatically collects certain technical information when you visit, including your IP address, browser type, operating system, referring URL, and pages viewed. This data is used for analytics and to maintain the security and performance of the Site.

2. How I Use Your Information

To create and maintain your account
To process purchases and deliver content you have paid for
To send transactional emails (purchase confirmations, password resets)
To diagnose errors and improve the Site
To comply with legal obligations

I do not sell your personal information. I do not send marketing emails unless you explicitly opt in.

3. Third-Party Services

The Site uses the following third-party services:

Stripe — payment processing. Stripe’s privacy policy: stripe.com/privacy
Cloudflare — content delivery, DDoS protection, and DNS. Cloudflare may process your IP address and request metadata. Privacy policy: cloudflare.com/privacypolicy
Sentry — error monitoring. Sentry collects technical diagnostic data (stack traces, browser info, IP address) when errors occur. Privacy policy: sentry.io/privacy
GitHub / Google — OAuth authentication. When you choose to sign in with one of these providers, their respective privacy policies apply to the data they share.

4. Cookies

The Site uses cookies and similar technologies for authentication (session cookies), security, and basic analytics. You can disable cookies in your browser settings, but doing so may limit your ability to use certain features such as logging in.

5. Data Retention

I retain your account information and purchase history for as long as your account is active or as needed to provide you access to purchased content. If you request account deletion, I will remove your personal data within 30 days, except where retention is required by law or necessary to resolve disputes.

6. Data Security

I take reasonable measures to protect your data, including encrypted connections (HTTPS), secure password hashing, and restricted access to databases. However, no method of transmission or storage is 100% secure, and I cannot guarantee absolute security.

7. Your Rights

Depending on your jurisdiction, you may have the right to:

Access the personal data I hold about you
Request correction of inaccurate data
Request deletion of your data
Object to or restrict certain processing
Request a portable copy of your data

To exercise any of these rights, please contact me through the About page.

8. Children’s Privacy

The Site is not directed at children under the age of 16. I do not knowingly collect personal information from children. If you believe a child has provided me with personal data, please contact me and I will delete it promptly.

9. Changes to This Policy

I may update this Privacy Policy from time to time. Changes will be posted on this page with an updated “Last updated” date. Your continued use of the Site after any changes constitutes acceptance of the revised policy.

10. Contact
