💡Quick Answer

Engineer data minimization into your application: audit PII collection points, remove unnecessary fields, shorten retention periods, restrict third-party data sharing to minimum required. Article 5(1)(c) compliant. Reduces your attack surface and compliance burden. Fixed price €2,700–4,500.

📋Why this service exists

Article 5(1)(c) data minimization principle: only collect personal data that is 'adequate, relevant and limited to what is necessary.' Most legacy applications over-collect — collecting email for 'just in case' or logging full request bodies containing PII. Minimization reduces breach impact and compliance burden simultaneously.

Frequently asked questions

Will removing PII fields break our application?

We audit usage of each field before removal. Fields actively used in business logic are flagged for discussion — we only remove those confirmed unnecessary. All changes go through your normal code review and deployment process.
