Thai PDPA (พ.ร.บ.คุ้มครองข้อมูลส่วนบุคคล พ.ศ. 2562)
Overview
A generic privacy notice translated from a GDPR template misses PDPA-specific requirements — most commonly, PDPA requires consent to be opt-in with no pre-checked boxes, and consent for non-essential purposes must be separable from the general terms of service. A model without this skill tends to produce a GDPR notice with Thai words substituted in, which reads as compliant but isn't structurally aligned with PDPA's consent mechanics.
Not legal advice. This skill drafts structure and language; it does not replace review by a lawyer or the organization's DPO before publishing a real privacy notice or consent flow.
When to use
- เขียน privacy notice / นโยบายความเป็นส่วนตัว สำหรับเว็บไซต์หรือแอป
- ออกแบบ consent banner / cookie consent ที่ไม่ติ๊ก checkbox ไว้ล่วงหน้า
- ตรวจสอบว่าข้อความขอความยินยอมที่มีอยู่เข้าข่าย dark pattern หรือไม่
- อธิบายสิทธิของเจ้าของข้อมูลส่วนบุคคลภายใต้ PDPA
When NOT to use
- Pure GDPR compliance work with no Thai data subjects — PDPA and GDPR overlap heavily (both are consent/rights-based frameworks) but have different specific requirements; don't cross-apply without checking
- The task needs a legally binding data processing agreement (DPA) between controller and processor — that's a contract-drafting task requiring a lawyer, not a template-fill task
Core knowledge
- PDPA = พระราชบัญญัติคุ้มครองข้อมูลส่วนบุคคล พ.ศ. 2562, in full enforcement since 1 June 2022 (after delayed effective dates for earlier compliance deadlines). Regulator is the PDPC (คณะกรรมการคุ้มครองข้อมูลส่วนบุคคล) via its office, the สคส.
- Valid consent must be: freely given, specific to each purpose, informed (clear language, not buried in T&Cs), and given by a clear affirmative action. No pre-ticked checkboxes — this is the single most commonly violated rule in copy-pasted GDPR templates.
- Sensitive personal data (มาตรา 26) — race/ethnicity, political opinion, religious belief, sexual behavior, criminal record, health data, disability, union membership, genetic/biometric data — requires explicit consent (a higher bar than general consent) or a specific statutory exemption. Do not lump sensitive-data consent into the same checkbox as general data processing.
- Legal bases beyond consent exist (contract performance, legitimate interest, legal obligation, vital interest, public task) — not every data use needs a consent checkbox; a privacy notice should state the correct basis per purpose, not default everything to "consent."
- Data subject rights: access, rectification, erasure, restriction of processing, data portability, objection, and withdrawal of consent. Withdrawal must be as easy as giving consent — a "call our office to unsubscribe" flow for something that was a one-click opt-in is itself a compliance gap.
- Cross-border transfer: transferring personal data outside Thailand requires the destination to have adequate protection standards or additional safeguards (e.g. contractual clauses, consent) — flag this explicitly if the notice covers a foreign-hosted service.
- Enforcement: administrative fines, criminal penalties for certain violations involving sensitive data, and civil liability including punitive damages are all possible under PDPA — this is a real regulatory regime, not a symbolic one, which is why the disclaimer in this skill is load-bearing.
Common mistakes
- Pre-checking a consent checkbox — the most common and most visible PDPA violation.
- One all-or-nothing consent checkbox covering multiple unrelated purposes (marketing + analytics + service delivery) instead of granular, purpose-specific consent.
- Translating a GDPR notice directly instead of checking whether PDPA's specific consent/rights language applies the same way.
- Treating "consent" as the only legal basis and forcing a checkbox even for processing that's actually necessary for contract performance.
- Making the "reject" button visually smaller, hidden, or harder to reach than "accept" (a dark pattern that undermines "freely given" consent).
- Not mentioning cross-border data transfer when the service is hosted or processed outside Thailand.
- No clear, low-friction path to withdraw consent later.

Known limitations
- PDPC guidance and enforcement practice continue to evolve since full enforcement began in 2022 — verify current PDPC notifications/guidelines (สคส. ประกาศ) for anything with real compliance stakes, especially sector-specific rules (health data, financial data, children's data).
- This skill does not draft data processing agreements, cross-border transfer contractual clauses, or breach-notification procedures — those need a lawyer.
- Templates here are structural drafting aids. Do not remove the "not legal advice" disclaimer when reusing or editing these files.
