Privacy Policy

Corsu is a service operated by Dudons LLC (EIN: 32-0765215), 30 N Gould St Ste R, Sheridan, WY 82801, United States. Questions? Email us at [email protected].

1. What we collect

When you sign up or use Corsu, we collect the information you provide directly: your name, email address, phone number, English level, and payment method. We also collect usage data automatically — such as your IP address, device type, and how you interact with our site — solely to improve the service.

2. How we use it

We use your data exclusively to deliver and improve the Corsu service: to set up your personalized English course, communicate with your assigned teacher, process payments, and send you progress updates. We do not sell your data to third parties.

3. Data retention

We retain your personal data for as long as your subscription is active and for up to one (1) year after it ends. After that period, your data is deleted or anonymized, unless we are required by law to keep it longer.

4. Your rights

You have the right to access, correct, or delete your personal data at any time. You may also object to or restrict how we process it. To exercise any of these rights, email us at [email protected]. We will respond within 5 business days.

5. Cookies

We use essential cookies to keep the site functional and analytics cookies to understand how visitors use it. By continuing to use Corsu, you accept this use. You can disable cookies in your browser settings at any time, though some features may not work as expected.

6. Third-party processors

Payments are processed by our payment provider (Stripe). We do not store your card details. We may share data with service providers strictly necessary to operate Corsu, all of whom are bound by confidentiality obligations.

7. Changes

We may update this policy from time to time. We will notify you of material changes by email or by posting a notice on the site. Continued use of Corsu after changes take effect constitutes your acceptance of the updated policy.
