PRIVACYNOTICE.

1. WHO IS RESPONSIBLE FOR THIS NOTICE

Yanko, Hong Kong operates the Yanko learning service and is responsible for the information described in this notice. Questions, requests, and complaints about privacy can be sent to beyondempyrean@qqatt.com.

Yanko is the public service name and Hong Kong is the service region stated on this site. This notice describes the service as it is offered to users; it does not replace any mandatory information supplied in a payment checkout, receipt, or legally required disclosure.

2. INFORMATION WE HANDLE

Account information includes the name, email address, authentication details handled through the account system, interface language, learning time zone, and settings you choose. When you contact support, we receive the information you send in that request.

Learning information includes selected word books, plans, session choices, answers, review results, progress, mistake patterns, topic-map outcomes, and learning statistics. This information is used to operate the study features you choose.

Service and session information includes the data needed to keep an authenticated session working, such as required session cookies and technical request information. We use this information to provide, secure, and troubleshoot the service rather than to build advertising profiles.

3. WHY WE USE INFORMATION

Yanko uses account and learning information to provide the workspace, save progress, schedule reviews, display statistics, restore your settings, respond to support requests, prevent misuse, and maintain the security and reliability of the service.

Your chosen time zone is used to present day-based learning and review information in a way that matches your local schedule. Browser speech, where available, is supplied by your browser or device; voice availability and browser-level processing are controlled by that platform.

4. COOKIES AND SIMILAR TECHNOLOGY

Yanko uses essential cookies or similar session technology to keep an authenticated account session working and to protect account actions. These are functional controls, not advertising cookies. Blocking essential session storage may prevent sign-in, account security, or saved-progress features from working correctly.

Yanko does not sell learning information or use it to target third-party advertising. If the service later introduces a non-essential analytics, advertising, or consent-controlled technology, this notice will be updated before that use begins.

5. SERVICE PROVIDERS AND PAYMENTS

Yanko may use carefully selected infrastructure providers to host the service, store data, deliver email, protect the application, or process a checkout that you choose to complete. Those providers may handle information only as needed to perform their service, protect the platform, or meet legal obligations.

Payment details are entered only into the checkout flow shown by Yanko and are handled by the payment provider for that transaction. Yanko does not ask users to send card numbers, security codes, passwords, or authentication codes by email.

6. RETENTION AND DELETION

Yanko keeps account and learning information while it is reasonably needed to provide an active account, maintain the learning record you expect, resolve a support issue, prevent misuse, or meet a legal obligation. You can request deletion through the account controls where available or by contacting support.

After an account deletion request is verified, Yanko will remove or de-identify information from active systems as technically practicable, except where a limited record must be retained for security, fraud prevention, dispute handling, legal compliance, or backup recovery. Backups are overwritten on their normal operational cycle and are not used to restore a deleted account except where necessary for service recovery.

7. YOUR CHOICES AND REQUESTS

You may ask for access to the personal information associated with your account, request correction of inaccurate account details, request deletion, or ask how your information is being used. Some requests may require identity verification so that Yanko does not disclose or change another user's information.

Send a clear request to beyondempyrean@qqatt.com from the account email where possible. We may need additional information to locate the account, understand the request, and apply any lawful limitation.

8. SECURITY

Yanko uses reasonable technical and organizational measures designed to protect accounts and learning information. No online service can guarantee absolute security. Keep your account credentials private, use a unique password, and contact support promptly if you believe your account has been accessed without permission.

Do not include unnecessary sensitive information in free-text support messages or learning inputs. If you report a security concern, describe the issue without sending credentials or payment secrets.

9. CHILDREN

Yanko is not designed for children under 16 to create an account without the involvement of a parent or legal guardian. If you believe a child has provided personal information without appropriate permission, contact support so we can review and take appropriate action.

10. CHANGES AND CONTACT

Yanko may update this notice when the service, data practices, or legal requirements change. The current version will be posted on this page with its updated date. For privacy questions or requests, contact beyondempyrean@qqatt.com.
