Cookie Policy

This website uses cookies and similar technologies to make the site work, remember your preferences, note which channel brought you here, and — with your consent — to measure traffic and for marketing. This policy explains the types we use and how you control them, in line with Thailand's Personal Data Protection Act B.E. 2562 (PDPA).

Strictly necessary cookies (always on)

Required for core functionality — no consent needed and they can't be switched off: login/session, cart, language choice (NEXT_LOCALE), remembering your cookie choice (pmd_cookie_consent), and a security session id.

Visit-source cookies (set before you choose)

When you arrive from another website or an ad link, we set our own cookie pmd_src to remember which channel brought you here — for example Google, Facebook, LINE or ChatGPT — and keep it for 30 days. It stores only the channel and campaign names, the name of the linking website and the time you arrived; it holds no ad-click ID and nothing that identifies you, and we do not pass it to any ad platform. When you place an order, we keep that channel with the order so we can see which ads and channels actually work.

We set this cookie from the first page you open, before you choose in the cookie banner, on the basis of our legitimate interest in measuring our marketing. If you don't want it, click “Reject non-essential” or switch off “Analytics” in cookie settings: we delete the cookie on the next page you open and record no source with your order.

If you arrive through a partner's referral link (a link with ?ref=, including sep.cx short links), we set pmd_ref (the partner code) and pmd_sl (the short-link code) for 30 days to calculate the commission for the partner who referred you. Neither holds anything that identifies you. They stay even if you reject non-essential cookies, because they are used to pay partners the commission we agreed with them; you can delete them at any time in your browser settings.

Analytics cookies (consent required)

Help us understand site usage anonymously so we can improve it — Google Analytics 4 and coarse location stats. These load only after you accept.

Marketing cookies (consent required)

Used for ad measurement and retargeting (e.g. Meta Pixel, TikTok Pixel, the OpenAI Ads Pixel for ads in ChatGPT). Off by default; they run only if you turn them on.

The OpenAI Ads Pixel (ads in ChatGPT) sets __oppref (the ad-click ID, kept 30 days), __oaiq_consent (remembers your choice, 30 days) and __obref (a browser ID, kept up to 1 year) to measure whether visits and orders came from an ad in ChatGPT. It also hashes (SHA-256) any email or phone number you type into a form on this site, inside your browser, before sending it to OpenAI — the actual value is never sent. If you are signed in, it also sends your account email and member ID, hashed (SHA-256) on our server first — again, never the actual values. Turning marketing cookies off stops the pixel immediately.

Managing cookies

You can change or withdraw consent at any time via the “Cookie settings” button below (and in every page footer), and you can block or delete cookies in your browser. Disabling necessary cookies may break parts of the site.

Your rights under the PDPA

You have the right to access, rectify, erase, object to, and withdraw consent for your personal data. Withdrawing consent is as easy as giving it.
