Privacy Policy

1. Who is responsible for your data

Your personal data is jointly controlled by two entities:

• Hộ kinh doanh Sol Park View Hotel (a registered household business): operates the hotel, receives deposits and serves guests.
• Cloud Valley Investment Joint Stock Company (Công ty CP Đầu tư Cloud Valley), tax code 0318387246: signs rental contracts and issues VAT invoices.

Address: Lô B17, KP Song Vĩnh, P. Tân Phước, Phú Mỹ, TP. Hồ Chí Minh. On this page, the two entities are together called "Sol". This policy covers Sol Park View Hotel and Sol Hotel & Apartment.

Sol processes data under the Law on Personal Data Protection No. 91/2025/QH15 (effective from 01/01/2026), Decree 356/2025/NĐ-CP guiding this law, and related regulations of Vietnamese law.

Website design, technical operation and security: Work Zone Technology Joint Stock Company, tax code 0318818615 (workzone.ai.vn). Work Zone processes personal data on Sol's behalf: only to run the website, chat box and automated assistant, on Sol's instructions, and never for its own purposes.

2. Summary table: what data, for what purpose, how long it is kept, who it is shared with

Sol does not sell personal data. Sol does not use your messages to advertise for third parties.

3. Data Sol collects and where it comes from

When you send a room reservation request on the website

You enter: full name, phone number, email (optional), company name, notes, stay dates, room type, number of guests. The system also records the page you just viewed, advertising parameters if you clicked through from an ad, and a hashed IP address. The hashed IP address is used only to block spam; Sol does not reverse it to the original address.

When you sign in

Sign in with Google: Sol receives your name, email and Google account ID. Sol does not receive or store your Google password. Sign in with phone number and booking code: Sol checks it against your existing booking.

Sol Rewards program

Nights and stays are added by the booking phone number, even if you do not sign in.

When you message Sol

On Facebook Messenger for the page facebook.com/solparkview, Zalo OA and the web chat, Sol receives the messages, photos and videos you send. For Messenger, Meta provides Sol with your page-scoped user ID (PSID) and public display name. Sol does not receive your password, friends list or Facebook email.

When you check in

The front desk records information from your ID card or VNeID, passport and visa to register your stay with the police under the Law on Residence and immigration regulations. This is a legal obligation of accommodation providers.

4. What Sol uses data for

• Carrying out your request: confirming and reserving rooms, billing, receiving deposits, welcoming guests, issuing invoices.
• Answering questions, quoting and after-stay care via the channel you messaged.
• Adding nights and stays and applying Sol Rewards offers.
• Meeting legal obligations: residence registration, accounting, tax.
• Keeping the system safe: preventing spam and detecting fake bookings.
• Knowing which channel guests come from in order to improve our service.

Sol processes data when needed to carry out a transaction you request, when the law requires it, or with your consent. When you choose to fill in a form or message Sol, that is the basis for Sol to process your data to fulfil that request. Sol does not use data for purposes other than those above without asking you.

5. Automated reply assistant and artificial intelligence

Messages sent to Sol's Facebook page, Zalo OA and web chat may be answered by an automated assistant. To draft replies, the conversation content is sent to an artificial intelligence service of an AI model provider. The front desk can read the conversation and take over when needed.

• Please do not send anything by message that Sol has not asked for: passwords, OTP codes, bank card numbers.
• The automated assistant's answers may be wrong. Final information on rooms, rates and bookings is what the front desk confirms.
• You always have the right to ask to speak with the front desk: message "talk to front desk" or call the hotline.

6. Data received from Facebook and Messenger

Sol's app on the Meta platform is used only to receive and reply to messages sent to the page facebook.com/solparkview.

• Data received: page-scoped ID (PSID), public display name, message content and files you send.
• Purpose: replying, quoting, reserving rooms, after-stay care. Not used for anything else.
• Sol does not sell, rent or transfer this data to data brokers or advertising networks.
• You can request deletion at any time by following the instructions on the Data deletion request page.

7. Cookies and browser storage

• Sign-in session cookie: set only when you sign in, valid for 30 days, and not readable by page scripts (HttpOnly). Signing out deletes the cookie.
• Browser storage (sessionStorage, localStorage): stores your search dates, language and latest booking so you do not have to enter them again. This data stays on your device; delete it by clearing your browsing data.
• Embedded Google Maps on hotel pages: Google may set its own cookies under Google's policy.
• Google analytics tools: when Sol enables them, they record page views and actions on the website as statistics.

Sol does not use cookies to track you on other websites.

8. Who Sol shares data with and where it is processed

Sol only shares data with parties that need it to do their part:

• Cloudflare: web server and booking database.
• Work Zone (workzone.ai.vn): designs, operates and secures the website. Work Zone accesses data only when needed to run, fix and secure the system.
• ota.ai.vn: Sol's automated assistant runs on the service at ota.ai.vn (Facebook), which stores conversations with the assistant.
• Telegram: sends new booking notifications to the front desk group.
• Meta and Zalo: the messaging channels you choose.
• AI model providers: draft replies for the automated assistant.
• VietQR: creates the QR code, which contains only the amount and transfer note.
• Google: sign-in, embedded maps, analytics tools when enabled.
• Government authorities: police, tax and other competent authorities when required by law.

Some of the parties above have servers outside Vietnam, so data may be processed abroad. Sol only transfers the data needed for the stated purposes.

9. How long Sol keeps data

• Bookings and invoices: for the period required by accounting and tax law. Sol keeps accounting records for 10 years.
• Conversations with the automated assistant: up to 24 months after the last message.
• Account and Sol Rewards: until you request deletion.
• Residence registration information: for the period required by residence and immigration law.

When the retention period ends, Sol deletes the data or removes personally identifying information from it.

10. How Sol protects data

• The website runs over an encrypted connection (HTTPS).
• Session cookies are signed and cannot be read by page scripts. IP addresses are stored only in hashed form.
• Only assigned front desk staff and managers can view bookings and conversations.
• Internal hotel information is not exposed to browsers or public data endpoints.
• System secrets are kept in encrypted environment variables, never in source code. The chat box talks to the automated assistant over a digitally signed channel to prevent forged messages.
• Website security is designed and operated by Work Zone Technology Joint Stock Company (workzone.ai.vn).

No system is completely secure. If an incident affects your data, Sol will notify you and the competent authorities as required by law.

11. Your rights

Under personal data protection law, you have the right to:

• Know what data Sol processes and why (this page).
• View and correct your data: sign in to the account page to view bookings and edit your name and email.
• Ask Sol to provide, correct, restrict processing of, or delete your data.
• Withdraw consent and object to data processing.
• Complain, file a lawsuit and claim compensation as provided by law.

How to request deletion, processing time, and the data Sol must keep by law: see the Data deletion request page. Sol processes requests within 7 working days, free of charge.

12. Children

The booking service is for people aged 18 and over. Sol does not knowingly collect data from people under 18 via the website or messaging channels. When children stay with adults, their information is recorded only for residence registration. Parents or guardians who find that a child has sent data to Sol can let us know and Sol will delete it.

13. Changes to this policy

When the way Sol handles data changes, Sol updates this page and shows the date at the top. For major changes, such as a new purpose of use or a new recipient, Sol posts them 7 days in advance and notifies you on the channel you use where possible.

14. Contact and complaints

Send any questions or requests about personal data to:

If you are not satisfied with how Sol resolves an issue, you have the right to complain to the competent state authority for personal data protection under the Ministry of Public Security, or to file a lawsuit at a competent court in Vietnam.
