What section 4 says, in plain English

Plain English

Not yet in force; the computed date is 13 May 2027, which is interpretation until officially confirmed. The summary below is what the provision says, not what is in force today. Status last checked 28 September 2026 against the MeitY library and India Code.

Personal data may be processed only under this Act and for a lawful purpose, and only on one of two grounds: the Data Principal has given consent, or the processing falls within the certain legitimate uses the Act lists. A lawful purpose means any purpose not expressly forbidden by law.

How 13 May 2027 is computed, and why it could be 1 day later

Publication date 13 November 2025 printed on Gazette issue No. 757, plus eighteen months. The notification states a period rather than a calendar date and does not state how the period is counted. The eGazette record of this same issue carries a code embedding 14112025, which would move the computed date by 1 day; the printed masthead date is used, and the interpretation label carries that uncertainty. CORRECTED 2026-08-25: this note previously also cited the Government's own PIB release for 14 November 2025. That release is about the DPDP Rules, 2025, G.S.R. 846(E) in Gazette issue No. 760, and says nothing about this Act commencement notification, G.S.R. 843(E) in issue No. 757. The missing space in the phrase "section 6,sections 7 to 10" appears as printed in the Gazette text layer.
