As a basic policy, we treat the contents of your study materials as your intellectual property. We do not share or secondarily use your study materials externally without your consent.

5.2 Service Providers (Processors)

We may share information with trusted service providers who process data on our behalf to provide the Service, such as:

• Stripe for subscription payments and customer billing management.
• Cloud infrastructure providers for hosting, storage, and database services.
• Security/anti-abuse providers (e.g., reCAPTCHA) to prevent automated abuse.
• AI providers (if enabled) to generate quizzes from your materials (see Section 6).

These providers are authorized to process information only as necessary to provide services to us and are expected to protect it consistent with this Privacy Policy.

5.3 Legal and Safety

We may disclose information if we believe in good faith that it is necessary to comply with law, respond to lawful requests, protect our rights and users, investigate fraud, or address security issues.

If we are involved in a merger, acquisition, reorganization, or sale of assets, your information may be transferred as part of that transaction. We will provide notice if required by law.

We store account and learning data in databases and store uploaded files (e.g., PDFs) in object storage, using cloud infrastructure as part of our architecture.

8.2 Security

We implement reasonable administrative, technical, and organizational safeguards designed to protect information. However, no method of transmission or storage is 100% secure.

8.3 International Transfers

Our service providers may process data in countries other than your country of residence. Where required, we take steps intended to ensure appropriate protection for cross-border transfers (e.g., contractual safeguards).

9.1 Retention

We retain information for as long as necessary to provide the Service, comply with legal obligations, resolve disputes, and enforce our agreements. Retention periods may vary depending on the category of data.

9.2 Backups

We may take automated backups of important databases at least once per day and maintain documented recovery procedures for critical user data (materials, quiz sets, learning history). Backups are used for recovery and are not intended for routine user access.

9.3 Deletion (Including “Hard Delete”)

10.3 Subscription Management

Billing and subscription changes are managed through Stripe’s customer tools (e.g., Customer Portal), which may provide additional privacy controls under Stripe’s policies.

10.4 Objections and Restrictions (Where Applicable)

Depending on your jurisdiction (e.g., GDPR), you may have rights to object to or restrict certain processing and to receive a copy of certain information. Contact us to exercise these rights.
