Privacy policy

Last updated 16 July 2026

Draft for launch — this is not legal advice. A qualified Vietnamese lawyer should review it before launch, in particular for compliance with the Personal Data Protection Law (Law No. 91/2025/QH15, effective 1 January 2026) and Decree 356/2025/ND-CP, including cross-border transfer paperwork and any data-processing impact assessment.

1. Who we are

HelpRent Da Nang (“we”, “us”) operates an online rental noticeboard for Da Nang, Vietnam. You can reach us through the HelpRent Da Nang bot on Telegram or the Mai chat on this site.

2. Scope and legal basis

This policy reflects Vietnam’s Personal Data Protection Law (Law No. 91/2025/QH15) and Decree 356/2025/ND-CP. We process your personal data on the basis of your explicit, specific, and informed consent, which you give in the bot before using the service and which you can withdraw at any time.

3. What we collect

Contact identity: your Telegram display name and @username — your verified contact for introductions.
What you tell Mai: your search criteria (city, area, budget, bedrooms, dates, pets) or, for Hosts, your listing details.
Activity: connection requests and introductions, and the messages you send to Mai (used to search; we do not store the renter–Host chat after contacts are exchanged).
Billing (Hosts only): the payment-proof image you send for a top-up, and your balance/ledger records.
Consent records: the fact, version, and time of your consent.
Analytics: events such as listing views, interest clicks, and connections, to operate and improve the service.

We use Google Analytics to understand how the site is used (see Cookies below). We do not use advertising cookies.

4. Why we use it

To match renters with suitable listings, deliver mutual contacts when both sides agree, bill Hosts for delivered introductions, moderate listings and prevent fraud and abuse, provide the Mai assistant and translate listing text, and analyse and improve the service. We follow purpose limitation and data minimisation.

5. AI processing

We use a third-party AI provider (DeepSeek) to power the Mai assistant, translate listing descriptions, and screen listings for fraud. The text you send to Mai and listing text may be sent to this provider for processing.

6. Where your data is processed (cross-border transfer)

Our hosting (Vercel) processes data on servers located in Singapore, and our database is hosted on our server in Germany (EU). Google (analytics, see Cookies below) processes usage data on its own infrastructure. Your personal data is therefore transferred to and stored outside Vietnam. By consenting, you agree to this cross-border processing; we will complete the cross-border transfer requirements under the Personal Data Protection Law as applicable.

7. Sharing

We share a renter’s and a Host’s contact details with each other only when both sides agree to connect. We rely on the processors named above (AI provider, hosting, database) to run the service. We do not sell your personal data.

8. Retention

We keep your data for as long as needed to provide the service and to meet legal and accounting obligations; consent records are kept for compliance. You can ask us to delete your data (see your rights below).

9. Your rights

Under the Personal Data Protection Law you have the right to be informed; to give and to withdraw consent; to access, correct, and request deletion of your data; and to object to or restrict certain processing. To exercise a right, contact us through the bot or the Mai chat on this site. Withdrawing consent may mean we can no longer provide the service to you.

10. Security

We apply reasonable technical and organisational measures to protect your data. No method of transmission or storage is completely secure.

11. Children

The service is intended for adults and is not directed at children. Do not use it if you are under 18.

12. Cookies

The website uses functional cookies — a session cookie (to keep you signed in where applicable) and a language-preference cookie — and Google Analytics cookies (_ga, _ga_*), which help us measure how the site is used (pages visited, approximate location, device type). Analytics data is processed by Google under its own privacy policy. You can block analytics cookies in your browser settings or with a content blocker; the site works fully without them. We do not use advertising cookies.

13. Changes

We may update this policy and will change the “last updated” date above.
