Overview
A developer-first view of GDPR. What counts as personal data, when the law applies, and how to design for privacy from the start.
When GDPR Applies
- You process personal data of EU residents - You offer goods/services to EU residents - You track EU visitors’ behavior (analytics, cookies)
Personal Data Examples
- Direct: name, email, phone, address - Indirect: IP, cookies, device IDs, user IDs
Privacy‑By‑Design Checklist
- Minimize data collection; make fields optional by default - [ ] Lawful basis per purpose (consent, contract, etc.) - [ ] Purpose limitation and retention schedules - [ ] Access, export, and delete endpoints for users - [ ] Encrypt in transit and at rest; audit access
Practical Tips
- Separate PII from behavioral data - Use consent mode and server‑side tagging - Document data flows in a lightweight data map
Conclusion
GDPR is manageable when you bake privacy into design and delivery. If you want a quick implementation plan for your stack, contact Keynodex: https://keynodex.com/?utm_source=blog&utm_medium=referral&utm_campaign=gdpr-compliance-software-applications
