Privacy Policy

1. Information We Collect

We collect the following information when you use Learn Your Way Tiếng Việt:

• Account information: email address and password (hashed, never stored in plain text), or your Google account identity if you sign in with Google.
• Learning progress: which lessons you have completed and quiz scores.
• Payment information: PayPal transaction IDs and payment status. We do not store credit card or bank details — all payment processing is handled by PayPal.
• Session data: a session token stored in a secure HTTP-only cookie to keep you logged in.

2. How We Use Your Information

• To create and manage your account.
• To display your learning progress and personalise your experience.
• To process payments for lifetime access.
• To send you important service-related notices (no marketing emails).
• To maintain the security and integrity of the platform.

3. Data Sharing

We do not sell, rent, or share your personal data with third parties, except:

• PayPal: for processing payments. PayPal's own privacy policy applies.
• Google: if you choose to sign in with Google, Google's privacy policy applies to that authentication step.
• Legal requirements: if required by law or court order.

4. Data Storage & Security

Your data is stored in a secured database. Passwords are hashed using Argon2, an industry-standard algorithm. Sessions use HTTP-only cookies to prevent JavaScript access. We use HTTPS to encrypt data in transit.

5. Cookies

We use a single essential session cookie (session_id) to keep you logged in. We do not use tracking or advertising cookies.

You may request access to, correction of, or deletion of your personal data at any time by contacting us. To delete your account, please email us and we will remove your data within 30 days.
