Data Minimization Under DPDP Act: Practical Guide for Businesses (2026)

Summarise on:

Data minimization under the DPDP Act means collecting, using, and storing only the personal data necessary for a specific purpose, and deleting it once that purpose is fulfilled. It reduces compliance risk, improves data security, and ensures lawful processing of personal data.

What Is Data Minimization Under DPDP?

Data minimization is a core DPDP principle.

In simple terms:

  • Collect only what is required
  • Use data only for a defined purpose
  • Delete it when no longer needed

If data is not needed, it should not exist.
