A founder running a health-tech app out of Chennai asked me a fair question last month. “We’re not huge yet. Do we really need to do a full impact assessment before launching this new feature?”
His new feature tracked patient symptoms and stored sensitive health data. That single detail changed my answer completely.
What a DPIA Actually Is
A Data Protection Impact Assessment, or DPIA, is a structured review. You run it before you start a new data processing activity that carries real risk. It helps you spot problems early. You find them on paper, not after a breach or a regulator’s notice.
Think of it as a risk check. You look at what data you plan to collect, why you need it, and what could go wrong. Then you decide how to reduce that risk before you launch.
Who Actually Needs to Do This
Under the DPDP Act, a Significant Data Fiduciary must carry out a DPIA. This isn’t optional for them. If your business gets classified as a Significant Data Fiduciary, based on factors like data volume, sensitivity, or your impact on India’s sovereignty and electoral integrity, a DPIA becomes a mandatory annual exercise.
But here’s the part many smaller businesses miss. Even if you’re not officially a Significant Data Fiduciary, a DPIA still makes sense whenever you touch high-risk data. Health information, financial records, biometric data, or data belonging to children all fall into this category. Good practice doesn’t wait for a legal threshold.
When to Run One
Run a DPIA before you launch anything new that touches personal data in a meaningful way. This includes:
- Launching a new app or feature that collects personal data
- Introducing a new tracking or analytics tool
- Rolling out facial recognition or biometric verification
- Building a product aimed at children or students
- Processing health, financial, or genetic data at scale
- Sharing data with a new third-party vendor for the first time
- Combining datasets from different sources into one profile
If any of these sound familiar and you skipped this step, it’s not too late. Run the assessment now, before the next major change.
What a DPIA Should Actually Cover
Description of the processing. Write down exactly what data you’ll collect, how you’ll use it, and why you need it in the first place.
Necessity and proportionality. Ask a hard question here. Do you really need all this data, or would less achieve the same goal? Regulators expect you to collect only what’s necessary.
Risk identification. List what could go wrong. A breach, misuse, unauthorized access, or data ending up with the wrong third party all count as real risks worth naming.
Risk mitigation measures. For each risk you identify, write down a specific control. Encryption, access restrictions, anonymization, or stricter vendor contracts often fit here.
Consultation. Talk to your DPO if you have one. Get input from your technical team too. A DPIA written by one person in isolation usually misses practical risks that a developer or product manager would catch instantly.
Sign-off and documentation. Keep a written record of the assessment, who reviewed it, and what decisions came out of it. This document matters if the Data Protection Board ever asks how you handled the risk.
A Real Example
Go back to that health-tech founder in Chennai. His new feature tracked patient symptoms daily and stored that data for future reference. A quick DPIA revealed two gaps immediately. The data wasn’t encrypted at rest, and the retention period had no defined end point.
Both fixes took his team about a week. Skipping the DPIA would have meant launching with those gaps live, and discovering them only after a breach or a user complaint. The assessment cost him a little time upfront. It saved him a much bigger problem later.
Don’t Treat This as a Paperwork Exercise
A lot of businesses treat a DPIA as a box-ticking formality, something to complete quickly and file away. That approach defeats the purpose. The value comes from actually thinking through the risks, not from having a document that says you did.
Involve people who understand your product, not just your legal team. The best DPIAs come from a genuine conversation between compliance, product, and engineering.
Getting Your DPIA Right
If you’re building something new that touches personal data, and you’re not sure whether you need a formal DPIA, it’s worth checking before launch, not after. Book a free consultation and we’ll walk through your specific situation together.
