Analytics tool review under the DPDP Act

Analytics tools are very good at counting clicks and occasionally forgetting they count people.

What to review

Analytics tools can appear harmless because they sit behind charts. In practice they may collect user IDs, device identifiers, IP addresses, page paths, search terms, feature events, transaction context, location signals and support metadata. Under the DPDP Act, the organisation deciding why analytics is used remains responsible for ensuring that personal data is processed for a lawful purpose, protected with safeguards and deleted when no longer needed.

The first review question is whether the tool receives personal data at all. Some analytics setups can work with aggregated or pseudonymous events; others pull in email addresses, account IDs and free-text fields. Product, engineering, marketing and privacy teams should agree on the event taxonomy before implementation, because one careless property can turn a clean event stream into an unnecessary personal data store.

The second question is vendor behaviour. Check hosting, support access, sub-processors, retention defaults, export options and whether the provider uses customer data for its own analytics, benchmarking or model training.

Analytics reviews work best when privacy, product and engineering share one event dictionary. The dictionary should state the event name, purpose, owner, fields, identifier type, retention period and downstream destinations. Without that record, teams often discover personal data only after dashboards, exports and warehouse tables have multiplied. Treat the dictionary as a control, not just documentation. A new event should be reviewed before code release, and deprecated events should be removed from collection instead of merely hidden from reports.

Implementation steps

1. List every web, product, mobile and business-intelligence analytics tool that receives user-level data, including session replay, heatmap and experimentation platforms.
2. Review the event taxonomy. Remove email addresses, phone numbers, free-text notes, identity documents, ticket content and other fields that are not needed for measurement.
3. Decide whether user IDs can be pseudonymous, rotated or scoped to the product instead of exposing direct identifiers.
4. Confirm the purpose and notice basis for analytics. Product improvement, security monitoring, campaign attribution and personalisation may require different explanations and controls.
5. Review vendor contracts for processing instructions, confidentiality, safeguards, sub-processor controls, breach support, deletion and restrictions on independent reuse.
6. Configure access by role. Product analysts, engineers, marketing users and vendor support staff should not all have the same export or admin privileges.
7. Set retention periods for raw events, session recordings, reports and exports. Keep longer retention only where the business reason is documented.
8. Test deletion and correction support. If an account is erased or corrected, know which analytics identifiers, exports and downstream reports are affected.

For mature products, test the analytics setup with real operational scenarios. Ask what happens when a user changes email address, deletes an account, opts out of optional tracking, raises a grievance, or appears in a session replay. Then check the tool, data warehouse and exports. This exercise often separates a well-governed analytics stack from one that has simply collected events for years. Record exceptions in the product backlog so remediation competes with other engineering work instead of living in a forgotten spreadsheet.

Common mistakes

• Sending direct identifiers into analytics events because it is convenient for debugging.
• Ignoring session replay and heatmap tools even though they may capture forms, typed text or screen content.
• Keeping raw event data forever while only reviewing the dashboard reports.

How DataNuance can help

DataNuance helps Indian product, engineering and privacy teams review analytics tools before data starts flowing. We can inspect event taxonomies, vendor contracts, retention settings, access roles and deletion paths, then turn the findings into a DPDP-ready control plan.

FAQs

Is analytics data personal data under the DPDP Act?

It can be. If events, identifiers or combinations of fields identify an individual or relate to an identifiable person, treat the data as personal data and apply appropriate controls.

Can analytics tools use pseudonymous identifiers?

Yes, where the product can still measure what it needs. Pseudonymous identifiers can reduce exposure, but they do not remove all privacy duties if re-identification remains possible.

Should session replay tools be reviewed separately?

Yes. Session replay can capture form entries, page content and user behaviour in a richer way than ordinary event analytics, so masking and access controls matter.

What should be checked before adding a new event?

Check purpose, data fields, identifier choice, notice alignment, retention, access, downstream exports and whether the event could reveal sensitive workplace, financial or health context.
