- Separated by purpose where necessary;
- Never inferred from silence, a pre-ticked box or a failure to reply;
- Withdrawable by the means set out in the section on viewing, correcting, deleting or restricting data.
Refusing or withdrawing consent to marketing does not affect your ability to book and use our services. However, if you do not provide the data required to verify identity, declare passengers, pay or fulfil a booking, Diamond Bay may be unable to provide all or part of the service.

As far as necessary and consistent with the purpose of processing, data may be accessed by or shared with:

- 05Auditors, accountants, legal advisers or other professional advisers bound by confidentiality;
- 06The agency or tour operator that made the booking, as far as necessary to manage and care for the customer;
- 07Competent state authorities on lawful request;
2.7Cross-border transfers
Some infrastructure, cloud storage, email, analytics, customer support or technology providers may host servers or process data outside Vietnam. Where personal data is transferred or processed across borders, Diamond Bay carries out the measures and procedures required by Vietnamese law, selects providers with appropriate security commitments and transfers only what the notified purpose requires.
2.8Retention periods
Diamond Bay keeps data for as long as needed to fulfil the purpose of processing and to meet its legal obligations. Retention is determined as follows:
- Advice or quotation requests that did not lead to a booking: at most 12 months from the last interaction, unless you agree to continued care;
- Marketing data: until you withdraw consent or unsubscribe, or after at most 24 months without interaction, whichever comes first, unless the law allows another period;
- User and partner accounts: while the account is active and for a reasonable period afterwards to settle balances, complaints, disputes and related obligations;
- Bookings, contracts, invoices, payments, accounting and tax records: for the duration of the transaction and the retention period required by the relevant legislation;
- Passenger documents: only for as long as needed to deliver the service, complete mandatory formalities and satisfy retention required by law or by a lawful request of a competent authority;
2.9Security measures
Diamond Bay applies organisational, technical and physical measures proportionate to the type of data, the scale of processing and the level of risk, including:
- Role-based access control and least-privilege permissions;

Data subjects may send a request to the personal data email address, through the contact form on the website, in writing to our head office, or by hotline to be guided through a verifiable request. The contact details are published in the company information block at the top of this page.

2.12Cookies and similar technologies
Diamond Bay may use:
- Essential cookies: to make the website work, keep a session open, provide security and remember mandatory choices;
- Functional cookies: to remember language, region and user preferences;
- Analytics cookies: to measure traffic, performance and how users interact with the website;
- Advertising and marketing cookies: to measure campaigns and show relevant content, where the user has consented.
The website must provide a tool for users to accept, refuse or adjust non-essential cookies. Essential cookies may be used to keep the website running without separate consent, as far as the law allows. You can also delete or block cookies in your browser, though some functions may then not work fully.
The specific list of cookie names, providers, purposes and lifetimes is maintained on the cookie settings page once the website implementation is complete.
2.13Marketing and unsubscribing
Diamond Bay sends marketing emails, messages or content only with the recipient's consent or on another basis permitted by law. Consent to marketing is kept separate from the consent needed to make a booking.
You can stop receiving marketing by:
- Clicking “Unsubscribe” in an email;
- Changing the settings in your account;
- Emailing the Diamond Bay support address;
- Calling the hotline.
After you unsubscribe from marketing, Diamond Bay may still send necessary notices about your account, booking, payment, itinerary changes, safety or legal obligations.
2.14Children's personal data
Diamond Bay may need to process children's data to make a booking, apply pricing policies, declare passengers and keep the journey safe. Processing is carried out only as far as necessary, in the best interests of the child, and with the consent of a parent, guardian or lawful representative where the law requires it.
Anyone booking for a child confirms that they are lawfully entitled to provide the data. If children's data appears to have been provided without authority, Diamond Bay may suspend processing and require verification or deletion as provided by law.
2.15Handling personal data incidents
On detecting an incident that could affect personal data, Diamond Bay takes the steps needed to contain it, assess it, limit the harm, remedy it and prevent recurrence. Diamond Bay notifies the specialist authority and the data subjects in the cases, with the content and within the deadlines required by law.
2.16Third-party links and services
The website may link to third-party websites, social networks, maps, payment gateways or services. Diamond Bay does not control and is not responsible for their privacy practices. Please read their policies before providing data.
Where Diamond Bay engages a third party to process data in order to deliver a service, appropriate security and processing obligations are imposed by contract and by law.
2.17Privacy complaints
Complaints, requests or reports about personal data may be sent to the personal data email address, through the contact form, by hotline or to our head office.
The procedure is:
- 01Receipt, with a request reference issued or confirmed;
- 02Verification of identity and of the scope of the request;
- 03Classification, investigation and coordination with the department or processor concerned;
- 04Notification of the outcome or of progress;
- 05Implementation of remedial measures, if any.
Diamond Bay gives an initial reply within 02 working days of receiving the necessary information and aims to resolve the matter within the statutory period. A complex case, or one requiring a third party, may take longer; Diamond Bay will report progress and explain why.
If you disagree with the outcome, you may continue to complain, denounce, sue or ask a competent authority to protect your rights under the law.
2.18Changes to this policy
Diamond Bay may update this policy to reflect changes in law, technology or its business. A new version is published in a prominent place on the website, stating the update date and the effective date.
If a change materially affects the purpose or scope of processing or the rights of data subjects, Diamond Bay will give appropriate notice and seek consent again where the law requires. An updated policy is not applied retrospectively in a way that reduces the lawful rights of data subjects.
2.19User confirmation
Before submitting a form, creating an account or booking a service, you are given a link to this policy and an appropriate way to express consent. By actively ticking the consent box and submitting your information, you confirm that you have read, understood and agree to the processing described, other than processing that does not require consent under the law.
