Cookie Policy

1. Introduction

This Cookie Policy explains how Siam Prosper ("we", "us", "our") uses cookies and similar tracking technologies when you visit our website at siamprosz.pro. It is intended to give you a clear and honest account of what we collect, why, and what choices you have.

This policy should be read alongside our Privacy Policy, which describes how we handle personal data more broadly.

If you have questions about any aspect of this policy, you are welcome to contact us at [email protected].

2. What Are Cookies

Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work reliably, to remember your preferences, and to provide information to the owners of the site about how it is being used.

In addition to cookies, we may use similar technologies such as pixel tags (sometimes called web beacons) and local storage. This policy covers all of these where relevant.

Cookies can be:

Session cookies — temporary files that expire when you close your browser.
Persistent cookies — files that remain on your device for a set period or until you delete them.
First-party cookies — set directly by our website.
Third-party cookies — set by external services we use, such as analytics platforms.

3. How We Use Cookies

We use cookies for the following purposes:

3.1 Strictly Necessary

These cookies are required for the website to function. They enable core features such as remembering your cookie consent preference. Without them, parts of the site may not work correctly. These cannot be disabled.

3.2 Analytics and Performance

We use Google Analytics (GA4) to understand how visitors use our website — which pages are visited, how long visitors stay, and how they arrive. This helps us improve the site over time. GA4 data is aggregated and anonymised; it is not used to identify individual visitors.

We also use Microsoft Clarity (Bing) for similar aggregate usage insights.

3.3 Marketing and Measurement

We use the Meta Pixel (Facebook) to measure the broad effectiveness of our promotional efforts — for example, whether visitors from a particular channel tend to enquire about our programmes. We do not use this to build detailed personal profiles or retarget individuals with advertising based on specific browsing behaviour.

4. Cookies We Use

The table below lists the main cookies active on this website at the time this policy was last updated.

This list may not be exhaustive. Third-party services sometimes update the cookies they set without prior notice to us. We review this table periodically and update it when we become aware of changes.

5. Your Choices

You have a number of ways to manage or limit the use of cookies:

5.1 Our Cookie Banner

When you first visit our website, a cookie notice is displayed. Accepting means you consent to analytics and marketing cookies in addition to strictly necessary ones. You may decline, in which case only strictly necessary cookies will be active.

If you wish to change your choice after the fact, you may clear your browser's local storage to reset the preference and the banner will reappear on your next visit.

5.2 Browser Settings

Most browsers allow you to refuse or delete cookies through their settings. The steps vary by browser; these links may help:

Please be aware that disabling cookies may affect the functionality of this and other websites you visit.

5.3 Third-Party Opt-Outs

You may also opt out of individual third-party services directly:

Google Analytics: Google Analytics Opt-out Browser Add-on
Meta (Facebook): Facebook Ad Preferences
Microsoft Clarity: Microsoft Privacy Statement

6. Legal Basis for Cookie Use

Under Thailand's Personal Data Protection Act B.E. 2562 (PDPA), the use of cookies that process personal data requires a lawful basis. For strictly necessary cookies, our lawful basis is legitimate interest in the operation of a functional website. For analytics and marketing cookies, our lawful basis is your consent, which you provide through our cookie banner.

You may withdraw your consent at any time using the methods described in Section 5 above.

7. Updates to This Policy

We may update this Cookie Policy from time to time — for example, if we add a new analytics service or if regulations change. When we update it, we will revise the "Last Updated" date at the top of this page. We encourage you to review this policy occasionally if you are interested in staying informed about how we use cookies.
