For a decade, Indian enterprises hoarded data like oil. We scraped numbers, bought lists, and treated CRMs as goldmines.
Under DPDPA , “Legacy Data” sitting in your servers from 2020–2025 is no longer an asset. It is a Toxic Asset.
“If you have concerns about the legacy data, you may wish to ask your HR department why it continues to retain Covid-19 vaccination information for the organisation’s workforce?”
The Legal Trap: The “Fresh Notice” Nightmare
The DPDP Act dropped a futuristic bomb on old data. Section 5(2) mandates that for all personal data collected before the Act, you must send a Fresh Notice to the user.
The Operational Reality:
If you send 1 million notices tomorrow to a 5-year-old list:
15-20% will bounce.
80-85% will ignore it (The “Grey Zone”).
The Trap: If you continue processing this “Grey Zone” data without a transparent audit trail confirming original consent, you’re essentially engaging in unlawful processing like a detached monk meditating over an ancient database, unaware of its true origins.
The “Detox” Advantage:
If you delete the bottom 30% of your database (unengaged, legacy users), you aren’t losing customers. You are shedding risk.
“A clean database of 10,000 consented users is an asset. A dirty database of 1 million strangers is a Dyamite to expose your bottom line.”
For CISOs: Data minimisation is your new control with fewer records mean fewer logs, fewer alerts, and a much smaller blast radius when something goes wrong.
For CXOs: Database “quality” should sit on your risk dashboard alongside revenue, churn, and NPA; this is now an executive‑level resilience metric.
For DPOs: Your credibility with the Board will increasingly depend on how aggressively you push for de‑identification, deletion, and provable erasure and not just on how well you draft policies.
Bottom line: In 2025, database size was a vanity metric; in 2026, database cleanliness is a survival metric. Trim the bloat, reduce your exposure, and protect the organisation.
