HAPPYBOOK TRAVEL SERVICES TRADING COMPANY LIMITED (abbreviated name: HAPPYBOOK TRAVEL; “HappyBook Travel”, “we” or “us”) is committed to protecting your personal data. This Policy explains how we collect, use, share, store and protect your personal data when you use the Website https://happybooktravel.com and HappyBook Travel's contact channels to book flights, hotels, tours, visas, insurance, eSIMs and other travel services. HappyBook Travel is the controller and processor of the personal data you provide to us.

By ticking the consent box at checkout, you confirm that you have read this Policy and agree to HappyBook Travel processing the information needed to fulfil your order (booking, payment, refunds, invoicing and order support). Sending offers and promotions is a separate purpose that we carry out only with your separate consent (for example, when you sign up to receive them); you may decline or withdraw this consent at any time without affecting your ability to book or use our services.

1. Purposes of Collecting Personal Data

• To process and confirm bookings, ticket issuance, tour confirmations, visa services, hotel reservations and other services you request.

• To process payments and refunds, issue invoices and reconcile transactions.

• To provide customer care and after-sales support, and to handle feedback, requests, complaints or suggestions.

• To send offers, promotions and updates on new services where you have agreed to receive them.

• To personalize our services and advice to your needs and preferences.

• To keep online transactions secure and to detect and prevent impersonation, fraud or unauthorized access.

• To comply with legal obligations (accounting, tax, invoicing) and requests from competent authorities.

3. How We Collect Data

We may collect personal data through the following channels:

• When you register an account or book a service on the Website.

4. Sharing of Data

HappyBook Travel does not sell your personal data. To provide the services you request, we share only the necessary data with:

• Payment gateways, banks and card schemes to process payments and refunds, prevent fraud and handle transaction disputes.

• Service providers supporting HappyBook Travel (hosting, email, SMS, e-invoicing, customer care), under equivalent confidentiality obligations.

For services with an international element (international flights, overseas hotels, visas, international eSIMs, etc.), the necessary data may be transferred to Suppliers or authorities outside Vietnam in order to provide the service you requested. HappyBook Travel carries out such transfers in accordance with Vietnamese law.

5. Data Retention

HappyBook Travel retains personal data:

• For as long as needed to provide the service and after-sales support;

• For the periods required by law for accounting records, invoices and transaction records;

• Or until you request deletion, provided that deletion does not conflict with HappyBook Travel's legal obligations.

Data is stored on secured server systems of HappyBook Travel and its infrastructure providers.

6. Data Security

We are committed to:

• Not sharing, selling or transferring your data to third parties other than as described in Section 4.

• Using encrypted HTTPS (SSL/TLS) connections for the Website and applying appropriate technical and organizational measures to protect data against unauthorized access, loss, leakage, alteration or destruction.

• Granting access to personal data only to staff and departments that need it to serve you.

• Notifying the competent authorities and you, as required by law, in the event of a data breach.

HappyBook Travel will never ask you for OTP codes, passwords or CVV/CVC codes by phone, text message or social media. If you receive such a request, please do not respond and report it to us immediately.

7. Cookies and Analytics

The Website uses cookies and similar technologies in three groups:

• Essential cookies: remember your language, keep you signed in and support booking and payment. The Website cannot work properly without them.

• Analytics cookies: measure traffic and how the Website is used so that we can improve your experience, through Google Tag Manager (Google's measurement tools) and Microsoft Clarity.

• Advertising cookies: measure advertising performance and show relevant ads on third-party platforms, such as Meta Pixel and advertising tags managed through Google Tag Manager.

The Website also includes a third-party live chat tool so that you can contact us; conversations are used only to assist you as described in section 1.

You can block or delete cookies in your browser settings and adjust your ad preferences in your Google and Meta accounts. Blocking analytics and advertising cookies does not affect your ability to book; if you block essential cookies, some Website features may not work properly.

8. Your Rights and Obligations

You have the right to:

• Be informed about the processing of your personal data;

• Request access to, correction of or deletion of the personal data we hold about you;

• Withdraw your consent, or request restriction of or object to the processing of your personal data, unless otherwise provided by law;

• Opt out of marketing communications at any time;

Withdrawing consent does not affect the lawfulness of processing carried out before the withdrawal, and may mean we can no longer provide certain services.

You are responsible for providing accurate information, keeping your account details secure and respecting other people's data rights. When booking on behalf of others (including children), you confirm that you have obtained the consent of that person or of their parent or guardian to provide their information.
