1. Who we are

Siamsai (สยามใส) is a cosmetics brand operated by Prime Pattaya Estate Co., Ltd., company registration 0205567071017, Pattaya, Chonburi, Thailand ("we", "us"). We are the data controller for the personal data described in this policy. Contact: [email protected].

2. Personal data we collect

• Messages and files you send to our business accounts on LINE, TikTok, Facebook, Instagram, Shopee or TikTok Shop chat, or by e-mail, together with your display name and the account identifier the platform gives us.
• Order details passed to us by TikTok Shop and Shopee so that we can deliver your order: name, delivery address, phone number and the products ordered. Payments are handled by the platforms - we never receive your card details.
• Contact details of business partners (company name, contact person, phone number, e-mail) and our correspondence with them.

Our website does not use tracking or advertising cookies.

3. How we use it

• to read and answer your messages and provide customer service;
• to process orders, deliveries and returns;
• to communicate with manufacturers, suppliers and other business partners;
• to keep records required by Thai law.

We use automated tools, including AI services, to translate messages between Thai, English and Polish and to prepare draft replies. Every message we send is reviewed and sent by a person.

4. Data from TikTok

If you message our TikTok business account, we receive your messages through the TikTok Business Messaging API. We use this data only to read your messages and reply to you. We do not use TikTok data for advertising or profiling, and we do not sell it or share it with anyone other than the service providers described in section 6. Access to our TikTok account is protected by tokens stored only in our own systems. You can ask us at any time to delete the messages we hold.

5. Legal basis

We process personal data under the Thai Personal Data Protection Act B.E. 2562 (2019): to perform a contract with you or take steps at your request (orders, replies), for our legitimate interests (running our business and communicating with partners), to comply with legal obligations, and with your consent where the law requires it.

6. Who we share it with

• the platforms you use to contact us or buy from us (TikTok, Shopee, LINE, Meta), under their own terms;
• delivery companies, to deliver your order;
• service providers who work for us - e-mail hosting (Zoho Mail) and AI translation (OpenAI) - only to the extent needed for the purposes above;
• public authorities, when the law requires it.

We do not sell personal data. Our systems run in Thailand; some service providers may process data outside Thailand, with the safeguards required by law.

7. How long we keep it

We keep messages and contact details while we are in contact with you and for up to 3 years after the last contact. Order and accounting records are kept for as long as Thai law requires. After that we delete or anonymise the data.

8. Security

Access to our systems is limited to authorised people and protected by login and encrypted connections.

9. Your rights

You have the right to access your data and receive a copy, to have it corrected or deleted, to object to or restrict its processing, to data portability and to withdraw your consent at any time. Write to [email protected] - we reply within 30 days. You can also complain to the Personal Data Protection Committee of Thailand.
