Section 3 gets you into the Act. Section 17 is where you might get carved back out
The Act's extraterritorial reach is broad on paper, it applies even to data processed outside India if that processing relates to offering goods or services to people in India, and applies within India regardless of where the data principal sits. That's the section most generic coverage stops at, which is why an Indian outsourcing business reading only the applicability section comes away thinking the law reaches everything it touches. The exemptions live in a separate section, and one of them is written for almost exactly this business.
The outsourcing exemption, and what it doesn't switch off
Section 17(1)(d) exempts processing personal data of people who are not in India, done in India under a contract with someone outside India, the standard dev-shop, BPO, or back-office arrangement. Where it applies, most of the Act's rights-and-consent machinery (Chapter II barring two sub-sections, Chapter III, Section 16) stops applying. What survives on purpose: Section 8(1)'s baseline rule that you're still accountable for complying with the Act even under a contract, and Section 8(5)'s duty to keep reasonable security safeguards. In plain terms, the exemption removes the consent-and-rights paperwork, not the basic duty to keep the data secure.
Why this isn't something to act on yet, in either direction
The Act commenced in three tranches. Only the Data Protection Board's own setup came into force on 14 November 2025. A narrow provision follows in November 2026. Everything else, the substantive Chapter II and III obligations this exemption would carve you out of, and Section 17 itself, is scheduled for 14 May 2027. So there's no live obligation to be exempt from yet, and no exemption to formally invoke yet either. The useful thing to do now is classify your own data flows honestly (which of your processing is genuinely foreign-client-only, and which touches an India-based employee or an India-facing customer) so you know where you'll stand once the remaining provisions actually commence.
