SMB Compliance Audit Checklist (GDPR + APPI) for Online Stores in Japan
Use this audit checklist to verify your online store’s data handling for GDPR and Japan’s APPI. It’s designed for small and medium-sized e-commerce teams and focuses on practical gaps you can close before regulators or customer complaints do.
How to use this checklist
- Pick one scope first: checkout, account, marketing emails, or customer support. Start where risk is highest.
- Score each item: “Ready”, “Partially ready”, or “Missing”.
- Keep evidence: screenshots, policy versions, data maps, vendor terms, and training logs.
- Assign owners: one person per workflow, with a due date.
Audit checklist for GDPR and APPI readiness
1
Data mapping and records
- Have you mapped personal data flows from landing page to checkout and post-purchase?
- Do you list data sources (forms, cookies, log data, customer support), purposes, storage locations, and retention periods?
- Can you identify what you share with processors or other recipients (payment, shipping, email, analytics)?
- Do you maintain an up-to-date inventory of vendors and their roles (processor vs. controller responsibilities)?
2
Lawful basis, consent, and marketing controls
- Do you clearly state why you collect data at each step (e.g., account creation, order fulfillment, fraud prevention)?
- For marketing, do you capture consent where required and store the evidence of consent?
- Do you provide easy opt-out mechanisms and honor them across email and SMS flows?
- Do you separate “service messages” from “marketing messages” so customers aren’t over-solicited?
3
Privacy notices and transparency
- Does your privacy policy reflect your actual data uses and categories of data collected?
- Are notices presented before or at the moment of collection (not hidden in a footer only)?
- Do you explain international transfers if applicable, including safeguards and recipients?
- Is your cookie and tracking disclosure accurate, including purposes and retention where known?
4
User rights and request handling
- Do you provide a clear path for access, correction, deletion, and objection-style requests where applicable?
- Is there a documented process to verify requesters and respond within expected timelines?
- Can you locate all systems and backup sources that store the user’s data?
- Do you log request status and maintain internal audit trails?
5
Security measures and incident readiness
- Do you enforce password and session protections for customer accounts?
- Are admin access controls restricted and monitored (least privilege, MFA where feasible)?
- Do you encrypt personal data in transit and at rest where your stack allows?
- Do you have an incident runbook for suspected breaches and evidence preservation?
- Is incident response coordinated across IT, operations, and legal review steps?
6
Vendor management and cross-border compliance
- Do you have data processing terms (or equivalent) with vendors that handle personal data?
- Do you verify that vendors meet security expectations and support audit or assurance needs?
- For international service providers, do you document transfer mechanisms and safeguards?
- Do you control and review changes to subprocessors or analytics tools?
7
Employee training and operational discipline
- Do customer support, marketing, and engineering teams know what they can and cannot do with personal data?
- Have you documented rules for handling downloads, exports, and ticket attachments?
- Do you test training with scenario-based checks (misrouted emails, over-collection, retention mistakes)?
- Is there a simple way for staff to request approvals for new tracking or new data flows?
8
Ongoing monitoring and retention controls
- Do you define retention periods per data type and enforce deletion or anonymization?
- Are cookie and tracking tools reviewed periodically, including re-consent rules?
- Do you monitor access logs and critical system events relevant to personal data?
- Do you track policy changes and keep a record of what changed and why?
