# Collect only the minimum personal data necessary
Collecting more data than necessary increases the blast radius of a breach, exposes your organisation to regulatory fines, and erodes user trust. GDPR Article 5(1)(c) makes data minimisation a legal obligation for any controller processing EU residents' data — but it is also sound engineering practice regardless of jurisdiction.
## Quick Reference
- Collect only fields your application actually needs to function
- Document the purpose for every piece of personal data you store
- Prefer anonymous or pseudonymous data over identifiable data where possible
- Clear client-side storage (localStorage, sessionStorage, cookies) on logout or after a defined retention window
- Never send raw PII to analytics, monitoring, or client-side logs
