Cookie Policy

1. What cookies are

Cookies are small text files placed on your device when you visit a website. They allow the site to remember your actions and preferences over time. We also use similar technologies such as local storage, which works in the same way but stores data directly in your browser.

2. Categories of cookies we use

• Strictly necessary — required for the site to load, route pages correctly, balance server load and protect against abuse. These cannot be switched off.
• Preference — remember choices you make, such as your selected language (English, Thai or Chinese), so the site loads the same way on your next visit.
• Analytics — help us understand which pages are viewed, how visitors reach us and where they encounter problems, so we can improve content and navigation. These are used in aggregate.
• Marketing — set by advertising or social platforms when you interact with embedded content such as a Facebook share button or an embedded YouTube video, and may be used to measure campaign performance.

3. Cookies set by this website

• step-lang — stores your language preference in local storage. Persistent until you clear your browser data. Category: preference.
• Session cookies — maintain your browsing session and site security. Deleted when you close the browser. Category: strictly necessary.

4. Third-party cookies

Some pages embed services operated by other companies, which may set their own cookies under their own policies.

• Google Maps — shows our office location on the Contact page.
• YouTube — plays embedded project and product videos.
• Facebook — powers the share button on our blog articles.
• Line — powers our official account contact link.

5. How long cookies last

Session cookies expire as soon as you close your browser. Persistent cookies and local storage entries remain until they expire or until you delete them. Preference values such as your language choice remain until you clear site data. Third-party cookie lifetimes are set by those providers.

6. Managing and deleting cookies

You can control cookies through your browser settings — block them, delete existing ones, or receive a prompt before a cookie is set. Please note that blocking strictly necessary cookies may cause parts of the site to stop working correctly.

• Chrome: Settings → Privacy and security → Third-party cookies / Delete browsing data.
• Safari: Settings → Privacy → Manage Website Data.
• Edge: Settings → Cookies and site permissions.
• Firefox: Settings → Privacy & Security → Cookies and Site Data.

7. Do Not Track

Browsers may send a Do Not Track signal. There is no common industry standard for responding to it, so our website does not currently change its behaviour in response to that signal. You can still control cookies using the browser settings described above.

8. Updates and related policies

We review this policy whenever we add or remove a service that sets cookies. For a broader explanation of how we handle personal data, please read our Privacy Policy. If you have questions about either document, contact us using the details below.
