DPDP Consent Manager: Cost, Build vs Buy
The DPDP Act gives data principals a registered consent-management layer between them and data fiduciaries. Here is what that actually requires, and whether to build or buy it.
The Digital Personal Data Protection Act introduces the Consent Manager as a registered intermediary that lets a data principal give, manage, review, and withdraw consent across multiple data fiduciaries through a single interface. It is a distinct role under the Act, with its own registration requirements -- not simply a consent pop-up on your website.
Do you need to be a Consent Manager, or just work with one?
Most companies processing personal data in India are data fiduciaries, not Consent Managers. As a fiduciary, your obligation is to obtain valid, specific, informed consent and to make withdrawal as easy as giving it. Becoming a registered Consent Manager yourself is a separate, much heavier undertaking, relevant mainly to platforms that aggregate consent across multiple fiduciaries.
What compliant consent actually requires
- Clear, itemised notice of what data is collected and why, in language the data principal can actually understand.
- Consent captured per purpose, not as a single blanket acceptance.
- A withdrawal mechanism that is genuinely as easy to use as the consent mechanism was.
- An audit trail proving when and how consent was given, retrievable on demand.
Build vs buy
Building an in-house consent-capture and audit-trail system is feasible for a company with existing engineering capacity and a relatively simple data flow, but the audit-trail and withdrawal-propagation requirements add more engineering time than most teams initially budget. Third-party consent management platforms shift that engineering cost into a subscription, and are usually the faster path to a defensible compliance posture.
The practical starting point
Map your actual data flows first -- what personal data you collect, from whom, and why -- before pricing either option. The cost of both build and buy scales with the number of distinct consent purposes and downstream systems that need to respect a withdrawal.
