┌──────────────────────────────────────────────────────────────┐
│ MANDATORY RULES FOR EVERY PRIVACY REVIEW │
│ │
│ 1. MAP EVERY PII FLOW BEFORE REVIEWING │
│ → You cannot assess privacy risk without knowing where │
│ personal data goes │
│ → Database columns, API payloads, log messages, error │
│ reports, analytics events, third-party APIs — every │
│ path must be documented │
│ → If you do not know where PII flows, you do not know │
│ where PII leaks │
│ │
│ 2. PII IN LOGS IS A BREACH WAITING TO HAPPEN │
│ → logger.info(`User ${email} logged in`) is a privacy │
│ violation in most jurisdictions │
│ → Log user IDs, not PII — never emails, names, IPs, │
│ or phone numbers │
│ → If you must log PII for debugging, it must be │
│ redacted within 24 hours │
│ → Log aggregation systems (ELK, CloudWatch, Datadog) │
│ inherit the same retention obligations │
│ │
│ 3. THIRD PARTIES ARE YOUR RESPONSIBILITY │
│ → Sending user emails to SendGrid, user behavior to GA4, │
│ error context to Sentry — each is a data transfer that │
│ needs a legal basis, a DPA, and purpose limitation │
│ → You are the data controller — processors act on your │
│ instructions, but you own the risk │
│ → Sub-processors (your vendor's vendors) extend the │
│ chain — you must know who they are │
│ │
│ 4. ANONYMIZATION MUST BE IRREVERSIBLE │
│ → Hashing an email without salt is pseudonymization, not │
│ anonymization — rainbow tables reverse it in seconds │
│ → True anonymization means the original data cannot be │
│ re-identified even with additional information │
│ → k-anonymity < 5 is insufficient for most datasets │
│ → Pseudonymized data is still personal data under GDPR │
│ │
│ 5. PRIVACY IS NOT A TOGGLE │
│ → "User opted out of analytics" does not mean their │
│ historical data disappears │
│ → Deletion, anonymization, and cessation of processing │
│ are three different things — each must be implemented │
│ → Consent withdrawal must propagate to all systems, │
│ including backups and third parties │
│ │
│ 6. NO AI TOOL REFERENCES — ANYWHERE │
│ → No AI mentions in privacy reports or findings │
│ → All output reads as if written by a privacy engineer │

└──────────────────────────────────────────────────────────────────────┘STEP 1: DATABASE SCHEMA SCAN
→ Read the database schema (Prisma, SQL DDL, ORM models)
→ Flag every column that stores PII
→ Check: are PII columns encrypted at rest?
→ Check: are PII columns indexed? (indexes are separate storage)
STEP 2: API PAYLOAD SCAN
→ Read every API route handler
→ For each endpoint, list: what PII enters (request) and exits (response)
→ Check: are responses filtered? (no password_hash in /api/users response)
→ Check: are request bodies validated and limited to necessary fields?
STEP 3: FRONTEND DATA COLLECTION
→ Read every form, input field, and data collection point
→ Check: what is stored in localStorage, sessionStorage, cookies?
→ Check: what analytics events fire, and what data do they carry?
→ Check: are there hidden fields or auto-collected data (IP, user agent)?
STEP 4: LOG AND ERROR TRACKING SCAN
→ Search for PII in log statements (see Phase 2)
→ Check: what context data is sent to error trackers (Sentry, Bugsnag)?
→ Check: do log aggregation systems have PII retention policies?
STEP 5: THIRD-PARTY INTEGRATION SCAN
→ For each external service, document what data is sent (see Phase 3)
→ Check: is data sent via server-side API or client-side SDK?
→ Client-side SDKs often collect more data than you intend┌──────────────────────────────────────────────────────────────┐
│ DATABASE PII AUDIT │
│ │
│ SCAN THE SCHEMA FOR PII COLUMNS │
│ → Search model/table definitions for these field names: │
│ name, first_name, last_name, email, phone, address, │
│ ssn, date_of_birth, ip_address, device_id, location, │
│ avatar, photo, bio, gender, ethnicity │
│ │
│ FOR EACH PII COLUMN, CHECK: │
│ □ Is this field necessary? (data minimization) │
│ □ Is it encrypted at rest? (column-level or disk-level) │
│ □ Is access to this table scoped by tenant_id? │
│ □ Is there a deletion mechanism for this field? │
│ □ Is this field included in database backups? │
│ □ Is the retention period defined and enforced? │
│ □ Can this field be anonymized instead of stored raw? │
│ │
│ SPECIAL ATTENTION │
│ → audit_log / activity_log tables — often contain full │
│ request bodies with PII embedded in JSON │
│ → search indexes — full-text search indexes duplicate PII │
│ → soft-deleted records — "deleted" data still exists │
│ → join tables — may expose relationships (user X in org Y) │

│ API RESPONSE PII AUDIT │
│ │
│ For every endpoint that returns user data: │
│ │
│ □ Is password_hash excluded from the response? │
│ □ Are internal fields excluded? (created_at, tenant_id │
│ may be acceptable — SSN, tokens are not) │
│ □ Is the response scoped to the requesting user's tenant? │
│ □ Are list endpoints paginated? (unbounded lists leak more) │
│ □ Do search endpoints return full objects or summaries? │
│ □ Are error responses free of PII? │
│ (e.g., "User with email X not found" leaks email) │
│ │
│ CHECK SELECT/INCLUDE PATTERNS │
│ → Prisma: does the query use select/include to limit fields?│

└──────────────────────────────────────────────────────────────┘┌──────────────────────────────────────────────────────────────┐
│ ANONYMIZATION vs PSEUDONYMIZATION │
│ │
│ PSEUDONYMIZATION (still personal data under GDPR) │
│ → Replace direct identifiers with tokens/IDs │
│ → Original mapping exists somewhere (lookup table, key) │
│ → Reversible — can re-identify the person │
│ → Examples: │
│ - user_id instead of name in analytics │
│ - Hashing email WITHOUT salt (rainbow table reversal) │
│ - Encrypting PII with a key you hold │
│ → Still subject to GDPR, CCPA, etc. │
│ │
│ ANONYMIZATION (no longer personal data) │
│ → Remove or transform data so re-identification is not │
│ reasonably possible │
│ → No lookup table, no key, no reversal path │
│ → Examples: │
│ - Aggregating to cohorts of 50+ users │
│ - Removing all direct identifiers + generalizing quasi- │
│ identifiers (age -> age range, zip -> region) │
│ - Differential privacy (adding calibrated noise) │
│ → Falls outside GDPR scope if done correctly │
│ │
│ AUDIT CHECKLIST │
│ □ Does the codebase claim to "anonymize" data? │
│ □ Is the technique actually anonymization or │
│ pseudonymization? │
│ □ Can the data be re-identified by combining with other │
│ datasets? │
│ □ For hashing: is a unique salt used per record? │
│ □ For aggregation: is the group size >= 5 (k-anonymity)? │
│ □ For differential privacy: what is the epsilon value? │
│ (epsilon > 10 provides weak privacy guarantees) │
│ □ Are anonymized datasets tested for re-identification │
│ risk? │
└──────────────────────────────────────────────────────────────┘┌──────────────────────────────────────────────────────────────┐
│ CONSENT AUDIT │
│ │
│ COLLECTION │
│ □ Is consent collected before processing begins? │
│ □ Is consent granular? (separate toggles per purpose) │
│ □ Is consent freely given? (no "accept all or leave") │
│ □ Is the consent text clear and specific? │
│ □ Is the consent record stored with timestamp, version, │
│ and the exact text shown? │
│ □ Is consent collected per legal basis? │
│ (analytics = consent, contract = performance of contract) │
│ │
│ STORAGE │
│ □ Where is consent stored? (database table, cookie, both) │
│ □ Can you query: "what did user X consent to, and when?" │
│ □ Is consent versioned? (if you change the privacy policy, │
│ old consents may be invalid) │
│ □ Is the consent record immutable? (append-only log) │
│ │
│ ENFORCEMENT │
│ □ Does the code CHECK consent before processing? │
│ (not just collect it — enforce it) │
│ □ If user declines analytics consent, do analytics scripts │
│ actually stop loading? │
│ □ If user declines marketing, are they excluded from │
│ marketing emails? │
│ □ Is consent checked server-side, not just client-side? │
│ │
│ WITHDRAWAL │
│ □ Can users withdraw consent? (GDPR Art.7(3)) │
│ □ Is withdrawal as easy as giving consent? │
│ □ Does withdrawal stop future processing? │
│ □ Does withdrawal trigger deletion of data collected │
│ under that consent? │
│ □ Does withdrawal propagate to third parties? │
