Privacy Policy

Last updated: 2026-8-26 (v2.0)

Chen Huiting ("CHT", "we", "us", or "me") respects and protects your privacy. This Privacy Policy (this "Policy") explains how we collect, use, store, and share your personal information when you use DolphinQuiz (the "Service"), and the rights you have under applicable law.

Please read this Policy carefully before using the Service. By using the Service, you confirm that you have read and agree to this Policy. We may update this Policy from time to time; the effect of updates is governed by Section 12.

1. Data Controller, Identity Statement, and Scope

The data controller of the Service is:

Name: Chen Huiting (CHT)

Status: an individual operating the Service as an individual developer, based in the Hong Kong Special Administrative Region of China, with service infrastructure (website hosting, database, email, payment processing) located outside the mainland territory of the People's Republic of China

Privacy contact email: huiting.chen@outlook.com

Data Protection Officer (DPO): not appointed at this time (as an individual developer, the data processing affairs are currently handled directly by me)

EU representative: not yet appointed under Article 27 of the GDPR; we will appoint one when the applicable threshold is met and update this Policy.

Special statement: you acknowledge that CHT provides the Service as an individual developer and is not a registered company or legal entity. As data controller, CHT processes personal data strictly within the scope and in the manner disclosed in this Policy.

Scope: this Policy applies to two categories of data subjects: (a) registered users (education institutions and their staff); and (b) quiz respondents (Guests) — potential customers who submit names, contact details, and other information through user quizzes. Respondent information is collected by the quiz operator (our user) as an independent controller, and we act as a processor in accordance with Section 11.5 of the Terms of Service.

2. Personal Information We Collect

2.1 Information Provided by Registered Users

Account information: name, email address, password (stored as an encrypted hash), phone number, team/company name.

Payment information: transaction amount, payment status, transaction time. We do not store full card numbers — card data is handled exclusively by the payment processor Waffo Pancake (see Section 5).

Communication records: emails, tickets, and feedback you send to support.

Other business-related fields: such as your institution name and job title.

2.2 Information Submitted by Quiz Respondents (Guests)

Information submitted through user quizzes: such as name, contact details, education-stage preferences, and other fields configured in the quiz. The scope of collection is determined by the quiz operator, who is responsible for establishing a lawful basis; we merely store and display the information on their instructions.

2.3 Information Collected Automatically

  • Device and network: IP address, device model, operating system, browser type, time zone.
  • Usage behavior: page views, feature usage, operation logs, session duration.
  • Log data: request time, error logs, performance data.
  • Location information: collected with your consent, used to improve service experience.

In the event of a security incident affecting your personal data, we will, in accordance with Articles 33 and 34 of the GDPR, report to the relevant supervisory authority within 72 hours of becoming aware and notify affected individuals where there is a high risk; for security incidents involving respondent data, we will notify the relevant quiz operator (user) within 72 hours and assist them in fulfilling their notification obligations.

Please keep your account credentials safe and do not share them with others.

With your consent, we may send marketing messages by email, SMS, or in-app notification.

You may unsubscribe at any time: click the unsubscribe link in any email; disable marketing preferences in account settings; or contact huiting.chen@outlook.com.

Service-essential notifications (billing, security, policy updates) are not affected by marketing unsubscription.

10. International Data Transfers

Our Service relies on the following third-party service providers; your data may be transferred to and stored in their countries/regions:

Website hosting and application services: Vercel (United States); database services: Neon (United States); email delivery services: Resend (United States); payment processing: Waffo Pancake (as described in its privacy policy); traffic analytics: Google Analytics (United States).

For services offered to you from the EU/EEA or the UK, we transfer data on the basis of the European Commission's Standard Contractual Clauses (SCCs); where appropriate, we also rely on the EU-US Data Privacy Framework (DPF). We have not yet completed SCC execution with all recipients, nor have we appointed an EU representative under Article 27 of the GDPR; we will complete these arrangements as the business scales, and in the meantime continue to take commercially reasonable measures to ensure a level of data protection no lower than that required by applicable law.

Where data transfers occur to Brazil, Switzerland, or other jurisdictions with localization requirements, the transfer mechanisms required by local law apply.

11. Children and Minors

The Service is aimed at education institutions, and their quizzes may involve information about minor students or their parents. We do not knowingly collect personal information from minors.

Where a quiz is designed to collect information from minors below the applicable digital age of consent in the relevant jurisdiction (16 in most EU member states; subject to local law), the quiz operator (user) must ensure that consent has been obtained from the parents or guardians and that a link to a privacy notice is provided at the start of the quiz or on the information-entry page.

Quiz operators should avoid collecting special categories of information — such as racial or ethnic origin, health status, or religious beliefs — through quizzes, unless they have a clear lawful basis and appropriate safeguards in place.

If we discover that minors' information has been collected without the necessary consent, we will delete that information. If you are a parent or guardian and believe your child has provided personal information to us or to our users, please contact huiting.chen@outlook.com.

12. Updates to This Policy

We may update this Policy from time to time. Materially adverse changes will be notified to you by email or in-app notification at least 14 days before taking effect; if you do not object before the effective date and continue to use the Service, you are deemed to have accepted them. Non-material changes take effect immediately, with a version history published on the website. We recommend that you review this Policy regularly for the latest version.

13. Language Precedence and Contact

This Policy is provided in both Chinese and English versions. In case of any discrepancy between the two versions, the English version shall prevail.
