The DPDP Act uses three job titles. You — the individual whose data is collected — are a Data Principal. The company that decides what to do with your data is a Data Fiduciary(everyone else calls this a “controller”). A company they hire to actually process the data is a Data Processor.
Almost every Indian-facing website, app, hospital, school, bank, insurer, shop, courier and government department is a Data Fiduciary when it comes to your personal data. Each of the five rights below applies to all of them.
