This Cookie Policy explains the cookies and similar storage technologies (localStorage, sessionStorage) used by iresthailand.com. It complements our Privacy Policy.
1. What is "similar storage"?
We rarely use traditional HTTP cookies. Instead, our site uses your browser's localStorage to remember a few small settings (consent choices, your visitor identifier, language preference). Under the EU ePrivacy directive and Thailand's PDPA, localStorage is treated equivalently to cookies for consent purposes.
2. Categories
We organise storage into four categories. You control all but the first via the consent banner.
Essential
Always on; cannot be turned off without breaking the site.
| Key | Purpose | Duration |
|---|---|---|
ires_consent | Records your consent decisions across categories. Without this, we would have to ask on every page. | Up to 12 months from last update |
Functional
Off by default. Off until you opt in.
| Key | Purpose | Duration |
|---|---|---|
ires_lang | Remembers your TH/EN language preference | 12 months |
ires_dossier_local | Caches your saved-property selections so they persist across sessions before you create an account | 6 months |
Analytics
On by default under our legitimate interest (GDPR Art 6(1)(f); Thai PDPA service-quality basis). Anonymous pageviews, clicks, and scroll depth only. No personal data is collected at this layer. You can opt out in the cookie banner.
| Key | Purpose | Duration |
|---|---|---|
ires_visitor_id (UUIDv4) | Anonymous random identifier so we can group your pageviews and dwell time across sessions. Not derived from any personal data | 24 months from last activity |
Marketing
Off by default. Off until you opt in. Powers our Behavioural Intelligence Design (BID) dossier system (search interactions, dossier opens, contact-intent signals feed personalised property recommendations) and ad measurement via Meta Pixel and Conversions API.
| Key / cookie | Purpose | Duration |
|---|---|---|
ires_visitor_id | Same UUID as above; required for BID inference | 24 months |
Meta Pixel (_fbp) | Facebook/Instagram ad attribution and Custom Audience matching | 3 months |
Meta Click ID (_fbc) | Click-through attribution for Meta ads | 7 days |
3. How to control your consent
The cookie banner appears on your first visit. You can:
- Accept all. Turn on all four categories.
- Essential only. Leave functional, analytics, and marketing off.
- Customize. Choose each category individually.
You can change your mind anytime: scroll to the footer and click "Cookie preferences" to reopen the banner. You can also wipe everything, including your visitor UUID, on /data-rights.
4. What happens if you opt out
- Opt out of Analytics: no
ires_visitor_idis used, no pageview or click events emit. The site still works; we just stop measuring how it performs for you. - Opt out of Marketing (the default): no Meta Pixel fires, no Conversions API events ship to Meta, no
_fbp/_fbccookies are set or forwarded. The site cannot personalise recommendations beyond the current session and we cannot measure paid-ad performance for your visit.
5. Your browser controls
You can also block or clear localStorage directly from your browser settings. Doing so will reset your consent record (the banner will reappear) and erase your visitor UUID.
6. Third-party cookies on linked sites
Linked external sites (developer pages, Google Maps embeds, Meta) set their own cookies under their own policies. We cannot read or control those.
7. Updates to this policy
If we add a new category or processor, the consent version is bumped and the banner reappears so you can review.
