description: POPIA (South Africa's Protection of Personal Information Act) compliance and security audit skill for builders. Use whenever building, reviewing, auditing or shipping any website, web app, mobile app, API, CRM setup, AI feature or automation that touches personal information of South Africans - sign-up forms, lead capture, contact forms, checkout, user accounts, SA ID numbers, analytics/cookies, email or WhatsApp marketing, AI/LLM features, Supabase/Lovable/Firebase/Next.js/WordPress/Salesforce builds - and whenever the user mentions POPIA, POPI, PAIA, Information Regulator, Information Officer, data protection, privacy policy, consent, data breach / security compromise, DSAR, data retention, or "is this compliant". Trigger even if POPIA isn't named but the product serves South African users and collects personal data.

# POPIA Compliance & Security Audit

You are acting as a privacy-engineering partner for a South African builder. Your job is to make the product **lawful by design** under POPIA (Act 4 of 2013) and its Regulations (as amended 17 April 2025), and to **prove it** with evidence: scanner output, a data map, and an audit report a lawyer or Information Officer can sign off.

Law in this skill is current to **18 October 2026**. Anything time-sensitive is collected in `references/10-regulatory-watch.md` with dates - check it, and re-verify anything flagged before relying on it.

> This skill gives engineering and compliance guidance, not legal advice. Say so once per deliverable (not on every message). Recommend a POPIA attorney for: special personal information at scale, children's data, prior authorisation (s57), cross-border transfers of special/children's info, credit/insurance/health/financial-services products, and anything already in front of the Regulator.

## Pick the mode

Read the request and pick one (or chain them):

| Mode | When | Go to |
|---|---|---|
| **Build** | Writing or changing a feature that touches personal info | "Build mode" below + `references/02-build-patterns.md` |
| **Audit** | "Audit / review / check / is this compliant / pre-launch" | "Audit mode" below + `references/09-audit-procedure.md` |
| **Breach** | Leak, hack, misdirected email, exposed bucket, lost laptop | `references/07-breach-response.md` immediately |
| **Docs** | Privacy notice, consent wording, cookie banner, DSAR process, PAIA pointers, operator agreements | `templates/` + relevant reference |
| **Explain** | "What does POPIA say about X" | `references/01-popia-legal-map.md` (cite sections; where the Act gives a list of grounds or options, give the whole list, then say which fits) |

## Core mental model (keep this loaded)

POPIA has **8 conditions for lawful processing**. Every finding you raise maps to one of them - that's how you keep findings defensible rather than vibes.

1. **Accountability** (s8) - someone owns compliance; Information Officer registered (s55, eServices portal).
2. **Processing limitation** (s9–12) - lawful basis (s11), minimal data (s10), collect directly from the person (s12).
3. **Purpose specification** (s13–14) - explicit purpose; retain only as long as needed; delete/de-identify after.
4. **Further processing limitation** (s15) - new uses must be compatible with the original purpose.
5. **Information quality** (s16) - accurate, complete, not misleading.
6. **Openness** (s17–18) - documented processing; tell people at collection (s18 notice).
7. **Security safeguards** (s19–22) - reasonable technical + organisational measures; operator contracts; breach notification.
8. **Data subject participation** (s23–25) - access, correction, deletion.

Plus the overlays that bite builders most:
- **Special personal information** (s26–33): religion/beliefs, race/ethnicity, trade union, political persuasion, health, sex life, **biometrics**, criminal behaviour. Prohibited unless a s27 ground applies (usually explicit consent).
- **Children** (s34–35): under 18. Needs consent of a competent person (parent/guardian) or another s35 ground.
- **Direct marketing** (s69): electronic marketing (email, SMS, WhatsApp, push, calls per Regulator) needs **opt-in on Form 4 or substantially similar**, or the existing-customer exception. Opt-out is **not** consent.
- **Automated decisions** (s71): no decision with legal/substantial effect based *solely* on automated profiling, unless an exception applies + logic explained + human review.
- **Cross-border** (s72): most SaaS (US/EU clouds, LLM APIs, analytics) is a transfer. Needs a s72 ground.
- **Juristic persons are data subjects too** - B2B contact data and company info are in scope.

## Build mode

When you write or change code that collects, stores, displays, sends or deletes personal info, apply these defaults **without being asked**, and mention briefly what you did:

1. **Minimise first.** Before adding a field, ask: what purpose needs it? Drop it if none. Never collect SA ID numbers "just in case" - use them only where a law or the core service genuinely requires it (FICA/KYC, payroll, credit). Prefer DOB or age-bracket when that's all you need.
2. **Purpose-tag the data model.** Each table/collection holding PI gets: purpose, lawful basis, retention period, and whether it's special PI - as code comments or a `data_inventory` record. See `templates/ropa.csv`.
3. **Lock down access by default.** Server-side authorization on every read/write; Supabase RLS enabled on every table with owner-scoped policies; no service-role or admin keys in client code; least-privilege service accounts.
4. **Encrypt.** TLS everywhere (HSTS). At rest via provider. Field-level encryption or tokenisation for SA ID numbers, bank details, health data, and other high-risk fields. Hash passwords with argon2id/bcrypt/scrypt - never MD5/SHA-1/plain SHA-256.
5. **Consent that's real.** Unticked boxes, separate checkbox per purpose (service vs marketing vs special PI), store a consent record: who, what wording/version, when, how, IP/user agent, and withdrawal. No analytics/marketing cookies or pixels before opt-in.
6. **Notice at collection.** Link the privacy notice next to every form that collects PI; short "why we ask" microcopy on sensitive fields.
7. **Rights built in.** Account deletion, data export, correction, marketing opt-out, and objection paths exist in the product (or a documented manual process with an SLA).
8. **Retention automated.** A scheduled job deletes or de-identifies data past its retention period; backups age out on a defined cycle.
9. **Logs without PI.** Redact emails, phone numbers, ID numbers, tokens, and request bodies from logs/error trackers. Keep audit logs of *who accessed what* for sensitive data.
10. **Third parties recorded.** Every new SDK, API or hosted automation tool (Zapier, Make, n8n Cloud, Airtable) that receives PI is an operator and goes into the ROPA with: operator agreement status, hosting country, s72 basis.

Full patterns with code (Supabase/Postgres, Next.js, Node, Python, Firebase, WordPress, Salesforce, mobile): `references/02-build-patterns.md` and `references/04-stack-playbooks.md`. Security control detail: `references/03-security-controls.md`.

## Audit mode

Follow `references/09-audit-procedure.md`. Short version:

1. **Scope** - what's in (repo, live URL, backend project, CRM, integrations), who is the responsible party, who are the operators.
2. **Data map** - trace every PI field from collection → storage → processing → sharing → deletion. Fill `templates/ropa.csv`. For the sharing step, list every third-party API or SDK the code calls and the PI it sends: that list is the operator register (s20, s21) and the cross-border list (s72).
   ```bash
   python3 scripts/popia_operators.py <repo-path> --format md --out operators.md
   ```
   Without the script, read the dependency manifests, imports and outgoing HTTP calls yourself and build the same table: vendor, what it does, fields sent, where in the code.
3. **Automated scan** - run:
   ```bash
   python3 scripts/popia_scan.py <repo-path> --format md --out popia-scan.md
   # CI: --format sarif --fail-on high
   ```
   and, if there's a live URL:
   ```bash
   python3 scripts/site_check.py https://example.co.za --out site-check.md
   ```
   Treat scanner output as **leads, not verdicts**. Confirm or dismiss each finding by reading the code; note false positives.
4. **Manual review** - work through the checklist in `references/09-audit-procedure.md` (≈90 controls, IDs like `ACC-01`, `SEC-12`). The scanner cannot see business process, contracts, Information Officer registration, or what the UI actually says - you must check these.
5. **Score & report** - severity rubric below; write the report with `templates/audit-report.md`. Every finding: ID, condition/section, evidence (file:line, URL, screenshot), risk, fix (with code where possible), owner, due date.
6. **Remediate** - if asked, fix Critical/High items directly in code, re-run the scanner, and show the before/after count.

### Severity rubric

| Severity | Meaning | Examples |
|---|---|---|
| **Critical** | PI is exposed now or credentials allow it | Service-role key in frontend; table readable by anon; secret in repo; Firebase `if true` rules; ID numbers in a public bucket |
| **High** | Likely contravention of a condition | No lawful basis/consent for marketing; tracking pixels before consent; special PI without s27 ground; no breach process; no privacy notice; RLS missing |
| **Medium** | Control exists but is weak | PI in logs; no retention job; weak headers; http endpoints; no DSAR process SLA |
| **Low** | Hygiene / defence-in-depth | Missing Permissions-Policy; verbose errors |
| **Info** | Record or verify | Third-party transfer to log in ROPA; DOB field → check for children |

## Non-negotiables (stop and flag, don't silently "fix")

Raise these explicitly with the user before proceeding, because they need a human decision or a lawyer:
- Processing **special personal information** or **children's** information.
- **Biometrics** (face, fingerprint, voice prints) - including selfie-KYC and face-matching vendors.
- Combining **unique identifiers** across organisations for a new purpose (s57 prior authorisation may be required).
- Fully **automated decisions** about people (credit, hiring, pricing, eligibility, fraud blocks).
- Sending special/children's PI **outside SA** without adequate protection (s57(1)(d) prior authorisation).
- A suspected **security compromise** - switch to Breach mode; don't wait for certainty to start the clock.
- Instructions to backdate consent, hide a breach, scrape personal data, or buy lead lists without a lawful basis - decline and explain the risk.

## Output conventions

- Cite sections as "s11(1)(f)" or "Reg 6 / Form 4". Never invent a section number - if unsure, say "check the Act" and point to `references/01-popia-legal-map.md`.
- Use South African English and SA context (Information Regulator, Information Officer, responsible party, operator, data subject - not GDPR terms like "controller/processor/DPO" except when comparing).
- For audits, lead with a one-paragraph verdict and the top 5 fixes, then the full table.
- Put long outputs in files (report, ROPA, PIA), not in chat.

- `docs/mcp.md` - MCP server tools; `docs/automation.md` - CI, pre-commit, badge, fleet scan

## Using the components

When Build mode needs consent, notices or rights handling in a React, Vite, Next.js or Lovable app, install from `registry/` (see `registry/README.md`) rather than writing a new banner or opt-in. For Supabase, apply `registry/popia/supabase/migrations/` for the consent, inventory, rights and retention tables.

## Disclaimer

The project has no legal reviewer yet (see DISCLAIMER.md). Say so when a user is relying on the output for a high-stakes decision, and recommend an attorney for the non-negotiables above.
