Clear information, collected for a clear reason.

• Enquiry details you choose to send, such as your name, contact details, pathway, year level, timing and question.
• For a student account, the name, email, preparation category and verification state you provide, a Better Auth-managed password hash and session metadata, plus saved attempts, answers, progress and feedback.
• Booking details you choose to send by SMS or email, such as the parent or guardian name and email, student year level, assessment format, consultation pathway, preferred days and times, and the page source when it is included in your message.
• If you request the full UCAT diagnostic report by email, the email address, consent time, allowlisted source and delivery/list-sync status. Answers are used in the request to calculate the report, but are not stored in the email lead record.
• For the invitation-only Selective Diagnostic, objective responses, assigned question paths, active response timing, progress, the student's optional writing sample, automated surface indicators, parent contact details and any optional planning context supplied.
• For the free adaptive-practice allowance, an opaque browser identifier or account identifier, the Sydney calendar date and a question count. The anonymous browser identifier is hashed before it is stored in D1.
• To limit automated abuse of diagnostic email routes, an endpoint-specific keyed hash derived from Cloudflare's connection IP, a bounded request count and the rate-limit window time. Zhou Education does not store the raw IP in this application rate-limit record.
• Basic website measurement events if analytics is enabled, and an allowlisted referral source or XHS campaign code used for up to 30 days. An expired browser record is removed the next time this site opens.

The invitation-only Selective Diagnostic is designed for a parent or guardian to initiate for a student in Years 4 to 6. It is a short adaptive diagnostic, not an official practice test, normed score or prediction of selective placement.

Zhou Education stores objective responses, the assigned question path, active response timing and progress so an attempt can be saved, resumed and used to create an evidence-linked parent report. If the student chooses to submit writing, the response is stored with surface indicators such as word, paragraph and sentence counts. The writing is not scored for quality.

The report-unlock form collects the parent's name and email. A phone number, WeChat contact, student year, target test year, target school, preparation level and parent goal are optional. These details are used to create and deliver the requested report, provide any requested strategy or preparation follow-up, protect the service and evaluate the beta. Access to the report does not require marketing consent, and optional marketing messages are sent only when the parent separately opts in.

An unfinished recovery draft may remain in the browser on the device used for up to 14 days or until completion, whichever occurs first. Anonymous attempt access expires 14 days after the attempt starts. Private report links expire 90 days after report unlock and should not be forwarded unless the parent intends to share the report.

Expired attempts and associated responses, writing, parent details, reports and delivery records become eligible for deletion after a further 30-day safety period. This means an unfinished attempt may be retained for up to 44 days after it starts, while an unlocked report and its associated records may be retained for up to 120 days after unlock. Non-personal question-bank versions may be retained for assessment auditability.

A parent or guardian can request earlier deletion by emailing nelsonzhou970@gmail.com with the full deletion reference shown in the report and the parent email used to unlock it. Zhou Education verifies both before deleting the student's diagnostic responses, writing, report, contact details and associated delivery records. Do not email the secure report token or the student's writing.

The enquiry planner and booking forms prepare a message on your device. Nothing is sent until you press send in your messaging or email app. The UCAT diagnostic can be sat without an account; its full report is emailed only after you provide an address and consent. Free UCAT practice does not ask for a name, date of birth or school report unless a signed-in feature clearly says otherwise.

Zhou Education does not take card payments and does not store payment details. Student account passwords are never stored in plain text; Better Auth stores a managed password hash. The separate owner administration sign-in does not disclose that provider's password to Zhou Education.

• Respond to enquiries and provide the agreed service.
• Keep signed-in practice private to the authenticated user and show their saved progress.
• Manage bookings, provide confirmed services, respond to cancellations or disputes and prevent misuse.
• Deliver a requested diagnostic report, maintain the consented UCAT preparation list and apply the configured daily free-practice allowance.
• Save and resume an invited Selective Diagnostic, create its evidence-linked parent report, email the private report link and evaluate the invitation-only beta.
• Understand which resources and campaigns lead to useful enquiries. Private account and administration pages do not load analytics.
• Meet record-keeping, safety, security and legal obligations.

Information is disclosed only where reasonably needed to operate the website and services, for example, to Cloudflare for hosting and D1 storage, Better Auth for the account system, Resend for account and requested diagnostic email plus consented contact-list management, messaging and email providers when you contact Zhou Education, and analytics providers if measurement is enabled.

These providers may process information outside Australia under their own infrastructure and privacy terms.

Zhou Education does not sell personal information or provide student answers, marks or enquiry text to XHS for advertising attribution.

Access controls, private server routes, secure cookies, managed password hashes, hashed invitation and report tokens, and rate limits are used where relevant. Account, report and signed-in practice pages are excluded from public search indexing where applicable.

Records are kept only for as long as reasonably needed for the service, security, dispute handling and applicable record-keeping obligations, then deleted or de-identified where practical.

You may ask what personal information Zhou Education holds about you, request a correction, or request deletion. Some service records may need to be retained where required for legal, tax, security or dispute purposes.

You can clear local practice or referral data using the controls provided in the relevant tool or your browser settings. You can also decline analytics through browser privacy controls where supported.

A parent or guardian should make the first enquiry and arrange the booking where the student is under 18. Do not send school reports, identity documents, health information or other sensitive material in an initial website enquiry unless Nelson has first explained why it is needed and how to send it safely.

Email nelsonzhou970@gmail.com with the subject “Privacy request”. Include enough detail to identify the relevant service, but do not email passwords, payment details or unnecessary student records.

Zhou Education will review the request, may verify identity before releasing or changing personal information, and will explain the outcome. If a privacy concern is not resolved, you may seek independent guidance from the Office of the Australian Information Commissioner.
