4. Cookies and Tracking

We use cookies in the following limited ways:

  • Security cookies: Used to protect against cross-site request forgery and other security threats.

We do not use advertising cookies, tracking pixels, or third-party analytics cookies. We do not participate in cross-site behavioral advertising.

5. Third-Party Services

To operate the Service, we share limited data with the following categories of third-party providers:

Payment Processing

We use a third-party payment processor to handle all financial transactions. Your payment details are transmitted directly to the processor and are never stored on our servers.

Authentication Providers

We offer sign-in via third-party authentication providers (e.g., social login) and email-based authentication. These providers share your name and email address with us when you sign in.

AI Content Generation

We use third-party AI services to generate book content. Your book preferences (language, level, genre, setting) are shared with these services to produce your book. No personally identifiable information is included in generation requests.

Cloud Storage

Generated books and cover images are stored using a third-party cloud storage provider. Files are associated with your account but do not contain personally identifiable information in the file content itself.

Email Delivery

We use a third-party email delivery service to send transactional emails. Your email address is shared with this provider solely for the purpose of delivering messages from us to you.

Database Hosting

Your account data, book metadata, and purchase history are stored in a managed database hosted by a third-party cloud provider.

Each of these providers is bound by their own privacy policies and data processing terms. We select providers who maintain appropriate security standards and comply with applicable data protection laws.

6. Data Storage and Security

We take reasonable technical and organizational measures to protect your personal data against unauthorized access, loss, destruction, or alteration. These measures include encrypted connections (HTTPS/TLS), secure authentication mechanisms, and access controls limiting who can view your data.

However, no method of transmission or storage is completely secure. While we strive to protect your personal information, we cannot guarantee absolute security.

7. Data Retention

We retain your personal information for as long as your account is active or as needed to provide the Service. Specifically:

  • Account data: Retained as long as your account is active
  • Generated books: Stored and accessible as long as your account is active
  • Transaction records: Retained for up to 7 years to comply with tax and accounting obligations
  • Support communications: Retained for up to 2 years after resolution

Upon account deletion, we will delete or anonymize your personal data within 30 days, except where retention is required by law (e.g., financial records).

8. Your Rights

Depending on your location, you may have some or all of the following rights regarding your personal data:

  • Access: Request a copy of the personal data we hold about you
  • Rectification: Request correction of inaccurate or incomplete data
  • Erasure: Request deletion of your personal data (subject to legal retention requirements)

International data transfers: Your data may be transferred to and processed in the United States or other countries where our service providers operate. Where such transfers occur, we rely on appropriate safeguards, including standard contractual clauses approved by the European Commission, to ensure your data remains protected.

Supervisory authority: If you are located in the EEA, you have the right to lodge a complaint with your local data protection supervisory authority if you believe we have not adequately addressed your concerns.

10. Children's Privacy

The Service is not directed to children under the age of 16. We do not knowingly collect personal information from children under 16. If we become aware that we have collected personal data from a child under 16, we will take steps to delete that information promptly. If you believe we may have collected data from a child under 16, please contact us at support@lenguapress.com.
