Privacy Policy

Who we are

This app is operated by Hunter Hsieh, who acts as the data controller for your personal information. If you have questions about this policy, contact us through the app or at the support email on the About page.

What data we collect

• Account data: name, email address, and login credentials when you create an account.
• Usage data: lesson progress, course selections, and feature interactions to provide the service.
• Device and technical data: browser type, IP address, and device identifiers for security and fraud prevention.
• Support data: messages and feedback you send us.

How we use your data

• To create and manage your account and provide the curriculum.
• To save your progress and personalize your learning experience.
• To maintain security, prevent fraud, and enforce our terms.
• To respond to support requests and improve the product.
• To send service-related updates (not marketing) when necessary.

Legal basis for processing

We process your data based on: (1) contract performance — to deliver the service you signed up for; (2) legitimate interests — for security, fraud prevention, and product improvement; and (3) consent — where you have explicitly agreed (for example, to analytics cookies).

Who we share data with

• Payment provider: Paddle.com acts as our Merchant of Record for subscription sales, subscription management, payments, tax compliance, and invoicing. Paddle processes payment data independently under their own privacy policy.
• Hosting and infrastructure: our backend and authentication providers, who process data only to host the service.
• Professional advisers: legal and accounting professionals, when necessary and under confidentiality obligations.
• Authorities: when required by law or to protect our legal rights.

Data retention

We keep your account and progress data for as long as your account is active. If you delete your account, we will remove or anonymize your personal data within 30 days, except where we need to retain it for legal obligations, fraud prevention, or enforcing our terms.

Your rights

Depending on where you live, you may have the right to access, correct, delete, or restrict processing of your personal data, and to receive a copy of it in a portable format. You may also object to processing or withdraw consent where applicable. To exercise these rights, contact us and we will respond within one month.

Security

We use industry-standard technical and organizational measures to protect your data, including encryption in transit, access controls, and secure authentication. No method of transmission over the internet is completely secure, but we work hard to keep your information safe.

Cookies

We use essential cookies to keep you signed in and maintain your session. We may use analytics cookies to understand how the app is used. You can manage cookie preferences through your browser settings.

Changes to this policy

We may update this privacy policy from time to time. If we make significant changes, we will notify you through the app or by email. Continued use of the service after changes constitutes acceptance of the updated policy.
