Welcome to Duc Nguyen (“we”, “us”, or “our”). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website or use our services.

This policy applies to information we collect through our website, apps, email communications, and other services that link to this Privacy Policy.

  • Usage data (pages visited, time spent on pages, clicks)
  • Device and connection information (device type, operating system)

2.3. Cookies and similar technologies
We use cookies and similar tracking technologies to remember preferences, enable functionality, analyze usage, and deliver personalized content or advertising where applicable.

2.4. Third-party data
If you authenticate via a third-party service (e.g., Google, Facebook), we may receive basic profile information from that service according to the permissions you grant.


3. How We Use Your Information

We use the information we collect for purposes including but not limited to:

  • Providing, maintaining, and improving our services
  • Responding to inquiries, and providing customer support
  • Processing transactions and sending administrative information
  • Personalizing user experience and content
  • Analyzing usage and trends to improve our services
  • Sending marketing communications (with your consent where required)
  • Detecting, preventing, and addressing fraud or security issues

4. Legal Bases for Processing (Where Applicable)

If you are located in a jurisdiction that requires us to identify a legal basis for processing (for example, the EU under the GDPR), we rely on one or more of the following:

  • Your consent
  • Performance of a contract with you
  • Compliance with legal obligations
  • Our legitimate interests (where such interests are not overridden by your rights)

5. Sharing and Disclosure

We may share your information with:

  • Service providers who perform services on our behalf (hosting, payment processors, analytics providers)
  • Business partners and affiliates where necessary to provide the service
  • Legal authorities when required by law or to protect rights and safety
  • In connection with a business transfer such as a merger, acquisition, or asset sale

We require third parties to use appropriate security measures and restrict use of your personal data.


6. Cookies & Tracking

You can manage cookie preferences via your browser settings. Blocking certain types of cookies may impact functionality. We may use third-party analytics and advertising partners that deploy cookies on our behalf.


7. Data Retention

We retain personal information only as long as necessary to fulfill the purposes described in this policy, comply with legal obligations, resolve disputes, and enforce agreements.


8. Your Rights

Depending on your jurisdiction, you may have the right to:

  • Access the personal data we hold about you
  • Request correction of inaccurate data
  • Request deletion or restriction of processing
  • Object to processing (including for direct marketing)

To exercise your rights, contact us using the details in the “Contact” section below. We may ask for information to verify your identity.


9. Security

We implement reasonable administrative, technical, and physical safeguards to protect your information. However, no security system is impenetrable — we cannot guarantee absolute security.


10. International Transfers

If we transfer your data outside your country, we will take steps to ensure that such transfers are performed with appropriate safeguards (e.g., standard contractual clauses, adequacy decisions where applicable).


11. Children

Our services are not intended for children under the age of 13 (or the age required by local law). We do not knowingly collect personal data from children without parental consent.


12. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page. Substantial changes will be notified where appropriate.
