Engineering for DPDP: Consent Ledgers, Retention Jobs and Breach Readiness

Store each consent as an immutable record: who, what purpose, what notice version, when, through which channel, and when it was withdrawn. Link every processing job to a purpose so you can stop it when consent is withdrawn.

Make withdrawal as easy as giving consent, which in practice means a self-service settings page and an API your support team can call.

Retention and deletion

Define a retention period per data category and purpose, and run scheduled jobs that delete or anonymise data when it expires. Remember backups, analytics copies, logs and third-party processors.

Deletion must be verifiable: log what was deleted and when, without keeping the data itself.

Children's data and access control

If your product may be used by children, build age signals and verifiable parental consent into onboarding rather than bolting them on later.

Restrict personal data by role, mask it in admin tools by default, and log every access to sensitive records.

Breach readiness

You need to answer three questions fast: what happened, which data principals were affected, and what you have done about it. Centralised, queryable logs and an incident runbook tested at least once a year make that possible. The core obligations, including breach intimation, apply from around May 2027.
