In manufacturing, most personal data sits at plants, depots and dealer networks, far from where policies are written.

Written for: DPO / Privacy lead, Manufacturing. Open this seat in the interactive tool

What is different here

Your biggest groups are workers you do not employ directly: contract labour through agencies. Next come health records for hazardous work, which the law requires and which must be tightly held. In fertilisers, farmer data passes through a government system and retailer devices, so you must be clear about what is yours and what is not.

The first four things to sort out

  1. List data by plant: gate, attendance, medical centre, canteen, hostel, CCTV.
  2. Map what manpower agencies and contractors hold for you, and sign data terms.
  3. Write down which farmer, dealer and consumer data is yours and which belongs to a scheme or a partner.
  4. Set up one grievance route for workers, dealers, farmers and consumers, with the 90-day limit.

A worked example

DPO / Privacy lead

A contract worker asks what the company holds about him

  1. Day 1A former contract worker writes to the grievance contact. The DPO's team logs it and checks his identity against the gate pass number and agency records.
  2. Day 5The team finds his data in the gate system, the biometric attendance device, the medical centre file and the agency's wage register.
  3. Day 10He receives a one-page summary listing each record, who holds it and why. His medical records are kept as the OSH Code requires; he is told he can see them.
  4. Day 12His biometric template and gate photo, no longer needed, are deleted. The agency confirms the same.

Evidence kept

  • Request log entry
  • Record list by system
  • Reply sent
  • Agency deletion confirmation

Contract workers are your data subjects too; the agency is part of your answer.

What others in the sector usually do. Manufacturers doing this well start with one pilot plant, build a simple data list there, and then copy it across plants.

10 questions the DPO / Privacy lead asks, answered in full

Contract workers, gate passes and biometrics: who is responsible for their data?

Short answer: You are, for data used at your plant; agencies act for you under contract

Your company decides why contract workers' data is collected at your plant: gate access, attendance, safety and the records the Labour Codes ask for. So for that data you are responsible, even when a manpower agency or contractor collects it. Agencies need a contract with data terms. Collect only what the gate and the law need, and delete biometric templates and photos when a worker leaves.

From your seat: DPO / Privacy lead. Agency workers will make requests too. Make sure the agency's records are part of your answer.
What the law says

Section 7 covers purposes of employment and duties under law. Section 8(1) keeps you responsible for processors. Section 8(7) asks for erasure when the purpose is over. Section 7 · Section 8(1)–(2) · Section 8(5) · Rule 6 · Section 8(7) · Rule 8 · Section 5 · Rule 3

Steps
  1. List what is collected for each contract worker: ID, photo, biometric, bank details, medical fitness.
  2. Remove what the gate and the Labour Codes do not need.
  3. Give a short notice in the worker's language at enrolment.
  4. Add a data schedule to every agency and contractor contract.
  5. Delete templates and photos at exit; keep only the registers the law requires.
Evidence to keep
  • Enrolment field list with reasons
  • Notice in local languages
  • Signed agency data schedules
  • Exit deletion log
Common mistakes
  • Agencies keeping their own copies of Aadhaar cards
  • Templates of workers who left years ago
  • Worker lists shared with contractors on chat groups

Worker medical records in hazardous processes: who may see them and how long do we keep them?

Short answer: The worker, the medical team and inspectors; others get only the fitness decision

Under the OSH Code, workers in hazardous processes have pre-employment, periodic and post-exposure medical examinations, and their health records are mandatory and accessible to the worker and to inspectors. Keep these records with the medical centre or occupational health team. HR and supervisors need only the fitness decision. Keep the records for the period the Code and state rules prescribe, then destroy them with a log.

From your seat: DPO / Privacy lead. A health record leak harms the worker most. Treat it as a priority breach.
What the law says

Section 7 covers duties under law and purposes of employment, so examinations need no consent. Section 8(5) needs strong safeguards. Section 11 lets the worker ask for a summary. Section 7 · Section 8(5) · Rule 6 · Section 8(7) · Rule 8 · Sections 11–14 · Rule 14 · Section 8(1)–(2)

Steps
  1. List where health records sit: medical centre, outsourced clinic, HR files, contractor files.
  2. Move all results to the medical team; give HR a fit, unfit or restricted note.
  3. Restrict access by name and log every opening.
  4. Give workers a simple way to see their own record.
  5. Set retention from the Code and state rules and destroy on schedule.
Evidence to keep
  • Record location list
  • Access list and logs
  • Fitness note format
  • Retention schedule and destruction log
Common mistakes
  • Blood and lung test results in HR personal files
  • Outsourced clinic keeping records with no contract
  • Contract workers' results held only by the agency

Farmer Aadhaar authentication at the retailer's PoS: who is responsible for what?

Short answer: The scheme flow is the government's; your own farmer programmes are yours

Subsidised fertiliser is sold through PoS devices at retailers, with Aadhaar-based farmer authentication on iFMS, a government platform built by NIC for the Department of Fertilizers. The scheme decides why farmer identity is collected in that flow. Your company sees sales data from it and supplies the retailers. Treat any farmer-level data you see as personal data, use it only for supply and subsidy work, and never for marketing. For your own farmer meetings, soil testing and agronomy apps, you are the Data Fiduciary with full duties. Get a written legal view on your role.

From your seat: DPO / Privacy lead. Own the written role view and keep scheme data out of marketing.
What the law says

Section 4 needs a lawful basis for each use. Section 6 needs consent for your own programmes. Section 8(1) and 8(5) apply to any data your staff, dealers or vendors handle for you. Section 4 · Section 6 · Section 8(1)–(2) · Section 8(5) · Rule 6 · Section 5 · Rule 3

Steps
  1. Write down which farmer data you see from the scheme, and which you collect yourself.
  2. Limit company dashboards and exports to what supply and subsidy work needs.
  3. Remind dealers and retailers not to keep Aadhaar copies or note numbers in registers.
  4. Give a notice and ask consent in your own farmer apps and meetings.
  5. Keep scheme data and marketing data apart in your systems.
Evidence to keep
  • Written role view
  • Dashboard access list
  • Dealer circular
  • Farmer app notice and consent records
Common mistakes
  • Using scheme purchase data to target offers
  • Retailers keeping Aadhaar photocopies
  • Farmer meeting registers kept for ever

What should our privacy notice say, and where must people see it?

Short answer: Yes, at every point where you collect data

A notice must tell people, in plain words, what data you collect, why, how they can withdraw consent, how they can use their rights and how they can complain to the Data Protection Board. It has to stand on its own, separate from long terms and conditions, and be shown at the point where data is collected.

From your seat: DPO / Privacy lead. You own the wording and the version history. Keep a folder with every live notice, its date and who approved it; that folder is usually the first thing an auditor asks for.
Example in Manufacturing

Gate pass forms, contract worker enrolment, the medical centre, dealer and mason app sign-ups and warranty cards each need a short notice, in the language people use.

What the law says

Section 5 and Rule 3 ask for a notice that can be understood on its own, with an itemised list of the data and the purpose for each item. Data you already hold from before the Act also needs a notice, as soon as reasonably practicable. Section 5 · Rule 3 · Section 6 · Sections 11–14 · Rule 14

Steps
  1. List every point where personal data comes in: forms, apps, counters, calls, emails, partner feeds.
  2. Write one short notice per collection point, with the data items and purpose side by side.
  3. Add how to withdraw consent, how to make a request and the DPO or contact person's details.
  4. Offer the notice in English and in the languages your workers and customers actually use.
  5. Keep each version with the date it went live.
Evidence to keep
  • Screenshots or copies of the notice at each collection point, with dates
  • Notice version history
  • Translations, where used
Common mistakes
  • Hiding the notice inside terms and conditions
  • One notice for everything, with no link between data items and purposes
  • Forgetting old data collected before the Act

Someone asks what data we hold about them. What do we send?

Short answer: Yes, a clear summary, inside the published timeline

Send a summary of the personal data you hold about them and what you do with it, and the names of the other organisations you shared it with and what was shared. Check the person's identity first, log the request and keep a copy of your reply.

From your seat: DPO / Privacy lead. Requests land with you even when the data sits with other teams. Agree a turnaround with each system owner in advance, so you are not chasing people on day 25.
Example in Manufacturing

A contract worker's summary should include what the agency and the medical centre hold for you.

What the law says

Section 11 gives the right to a summary and the list of organisations it was shared with. Rule 14 asks you to publish how requests are made and to answer within the period you publish. Sections 11–14 · Rule 14 · Section 8(9)–(10) · Rules 9, 14

Steps
  1. Log the request in one register the day it arrives.
  2. Verify identity using details you already hold.
  3. Search every system, including vendors' copies.
  4. Write a plain summary: what data, why it is used, who received it.
  5. Send it, and file the request, search notes and reply.
Evidence to keep
  • Request register
  • Search notes for each request
  • Copy of each reply with date
Common mistakes
  • Sending raw database dumps
  • Forgetting data held by vendors
  • No identity check before sending

How do we handle a privacy complaint within 90 days?

Short answer: Reply within your published period, never beyond 90 days

Publish one clear way to complain, log every complaint, give it an owner and reply within the period you publish, never more than 90 days. People can go to the Data Protection Board only after using your process, so a good process keeps most matters with you.

From your seat: DPO / Privacy lead. Count the days yourself. A short monthly note to management with open complaints and their age keeps the 90-day limit visible.
Example in Manufacturing

Workers raise data concerns through supervisors and unions. Log them in the same register, within the 90-day limit.

What the law says

Section 8(10) requires a working grievance process. Rule 14(3) caps the reply time at 90 days. Section 13 says people must use your process before approaching the Board. Section 8(9)–(10) · Rules 9, 14 · Sections 11–14 · Rule 14 · Sections 18–26

Steps
  1. Publish one contact for privacy complaints on your website, app and notices.
  2. Log each complaint with the date, channel and a named owner.
  3. Acknowledge within a few days, and set an internal target well under 90 days.
  4. Find and fix the cause, not just the single case.
  5. Reply in writing and close the entry with the date.
Evidence to keep
  • Complaint register with dates
  • Replies sent
  • Monthly summary to management
Common mistakes
  • Mixing privacy complaints into general complaints with no tag
  • No owner, so nobody counts the days
  • Closing a complaint without fixing the cause

How long can we keep personal data?

Short answer: For the legal or business period, then erase

Keep data for as long as its purpose needs, or as long as a law requires, and then erase it. Every organisation must keep personal data and logs for at least one year under Rule 8(3). Write a retention schedule by record type, with the law or reason against each period.

From your seat: DPO / Privacy lead. Draft the schedule, but get Legal and each department head to sign their rows. Your role is to make sure deletion actually happens.
Example in Manufacturing

Set periods from the Labour Codes, the chemical rules and the fertiliser order, record type by record type.

What the law says

Section 8(7) asks for erasure when the purpose is over, unless a law requires retention. Rule 8(3) sets a one-year minimum for personal data, traffic data and logs. Section 8(7) · Rule 8 · Section 8(5) · Rule 6

Steps
  1. List the record types you hold.
  2. Write the period for each, with the law, regulator rule or business reason.
  3. Set a trigger for the period to start: end of relationship, date of transaction, exit date.
  4. Automate deletion where you can; for paper, schedule shredding.
  5. Keep a deletion log.
Evidence to keep
  • Retention schedule approved by Legal
  • Deletion log
  • Shredding or disposal certificates
Common mistakes
  • 'Keep everything forever' because storage is cheap
  • Deleting before the legal minimum
  • Forgetting email, shared drives and backups

Do we process children's data, and what changes if we do?

Short answer: Check every channel; children often appear where you least expect

Anyone under 18 is a child under the Act. For a child's data you need verifiable consent from a parent or lawful guardian, and you must not track, behaviourally monitor or show targeted ads to children. Some classes and purposes are exempt under Rule 12 and the Fourth Schedule, for example healthcare to the extent needed to protect the child's health, and educational institutions for their educational work.

From your seat: DPO / Privacy lead. Ask every team, not only marketing. Dependants, interns, scholarship applicants and visitors are where children's data usually hides.
Example in Manufacturing

Product contests and school promotions may reach children. Parent consent and no targeted ads apply.

What the law says

Section 9 sets the duties. Rule 10 explains how to verify the parent. Rule 12 and the Fourth Schedule list the exemptions. Section 9 · Rules 10, 12 · Section 6

Steps
  1. Find where children's data enters: customers, dependants, interns, visitors, scholarships, app sign-ups.
  2. Decide whether an exemption in the Fourth Schedule applies to that purpose.
  3. Where none applies, add an age question and a parent-consent step.
  4. Switch off tracking and targeted ads for under-18 users.
  5. Record the decision for each channel.
Evidence to keep
  • Channel-by-channel note on children's data
  • Parent-consent records
  • Ad and tracking settings
Common mistakes
  • Assuming 'we are B2B, so no children'
  • Using the age 13 or 16 from foreign laws
  • Treating a tick-box from the child as parental consent

Something has gone wrong. What happens in the first 72 hours?

Short answer: Six hours for CERT-In; without delay for people and the Board; 72 hours for the detailed report

Contain it, then tell people. A reportable cyber incident goes to CERT-In within six hours of being noticed. Under DPDP, each affected person and the Data Protection Board must be told without delay, and the Board needs a detailed report within 72 hours. Sector regulators may have their own clock too.

From your seat: DPO / Privacy lead. You decide whether people and the Data Protection Board must be told, so you must be on the first call, not informed the next morning.
Example in Manufacturing

A stolen gate server or a lost medical register is a breach. CERT-In's six hours and the DPDP steps may both apply.

What the law says

Section 8(6) and Rule 7 set the DPDP steps. The CERT-In Directions of 28 April 2022 set the six-hour report. A breach includes accidental disclosure and loss of access, not only hacking. Section 8(6) · Rule 7 · Section 8(5) · Rule 6

Steps
  1. Name one incident lead and a back-up, with phone numbers that work at night.
  2. Write the first-hour steps: isolate, preserve logs, tell the DPO and the incident lead.
  3. Keep ready-made drafts for CERT-In, the regulator, the Board and affected people.
  4. Decide in advance who signs off each message.
  5. Rehearse once a year with the people who would actually be called.
Evidence to keep
  • Incident plan with clocks
  • Rehearsal record
  • Incident log with times of each step
Common mistakes
  • Waiting to finish the investigation before telling anyone
  • Treating a wrong email or a lost laptop as 'not a breach'
  • Only IT knowing the plan
