Module 12 Summary

What this module established

Log lines contain user input and retrieved documents, and the user id links them to a person - so audit the log store with the same care as the database.

Carry forward

• Redact structured identifiers before writing, and treat it as reduction rather than removal. Free-text personal data matches no pattern.
• Set retention per field. One policy forces you to over-retain the sensitive part to keep the metrics.
• Write the privacy notice from the code and the provider's terms. Every claim should be checkable, especially the deletion path.

Before moving on

Move on when redaction happens on write, retention differs by field, and your deployment checklist is empty.
