5. Cookies and Similar Technologies

eng20w does not currently use third-party advertising or analytics cookies.

Our website uses technologies necessary for authentication and core functionality. For example, our authentication provider, Supabase, may store authentication session information in browser storage to keep you signed in and maintain your authenticated session.

You can clear or control browser storage through your browser settings. Doing so may cause you to be signed out or may affect features that require an active account session.

6. Service Providers

Supabase

Supabase provides infrastructure used by eng20w for services including authentication, database functionality, backend services, and related infrastructure.

Your account and learning-related information may therefore be processed through Supabase infrastructure.

PayPal

PayPal provides payment processing for paid subscriptions.

When you make a payment through PayPal, PayPal may process personal and financial information according to its own privacy policies and applicable requirements. PayPal's processing is governed by PayPal's applicable privacy documentation.

7. Data Storage and Processing

Information associated with your eng20w account and use of the service is stored and processed using our service infrastructure and third-party providers such as Supabase.

eng20w uses Supabase Storage for learning-related images used by the service. We do not currently provide a feature for users to upload personal files or personal photographs for storage in their accounts.

8. International Data Processing

eng20w is a global online service.

Because we use third-party service providers, your information may be processed or stored in locations determined by those providers' infrastructure and applicable service arrangements.

Where required by applicable law, we will take appropriate measures concerning international processing and applicable data protection requirements.

9. Data Retention

We retain information for as long as reasonably necessary to:

• Provide and maintain your account and the eng20w service
• Maintain your learning progress
• Manage subscriptions and payment records
• Respond to support requests
• Meet applicable legal, accounting, security, or dispute-resolution requirements

When information is no longer reasonably necessary for these purposes, it may be deleted or otherwise handled in accordance with applicable requirements.

10. Data Security

We use reasonable technical and organizational measures designed to protect information against unauthorized access, loss, misuse, alteration, or disclosure.

These measures may include authentication controls, access controls, secure communications, and database security provided through our service infrastructure.

However, no online service can guarantee absolute security.

11. Your Privacy Rights

Depending on where you live and the laws applicable to you, you may have rights regarding your personal information.

These may include the right to:

• Request access to personal information we hold about you
• Request correction of inaccurate information
• Request deletion of your information
• Request information about how your information is processed
• Withdraw consent where processing is based on consent
• Exercise other rights provided by applicable privacy laws

We may need to verify your identity before completing certain requests.

12. Children and Younger Users

eng20w is designed to support English learners of different ages.

We do not currently impose a fixed minimum age in this Privacy Policy. Where applicable law requires parental or guardian involvement or consent for the collection or processing of information from younger users, those requirements apply.

Parents or guardians who have questions about information relating to a younger user may contact us at:

13. Third-Party Services and Links

eng20w may rely on third-party services to provide certain functionality, including authentication, infrastructure, and payment processing.

Third-party services operate under their own terms and privacy policies. We encourage you to review the applicable privacy information provided by those services.

eng20w is not responsible for the privacy practices of third-party services outside our control.

14. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to the eng20w service, our practices, technology, or applicable requirements.

When we make changes, we will update the Last Updated date at the top of this Privacy Policy.

Your continued use of eng20w after an updated Privacy Policy becomes effective means that the updated policy applies to your use of the service, to the extent permitted by applicable law.
