DPDP Action Sheet
Use this before your next workflow goes live. It keeps the useful parts visible and turns DPDP into checks your team can actually answer.
For Construction Tech DPDP Guide, the DPDP question is how personal data enters the workflow, where it is stored, which tools touch it, what purpose was explained, and how deletion or withdrawal will work.
1. Lead Forms
Check:
- What data are you collecting?
- Is the purpose clear at the point of collection?
- Is marketing consent separate from service communication?
- Can the user withdraw consent later?
Common mistake: one checkbox that silently covers newsletters, sales calls, partner sharing and remarketing.
2. Email and WhatsApp
Check:
- Who is on the list?
- Where did consent come from?
- Is the list imported from a vendor, event, webinar, scrape or old CRM?
- Can you prove the source of consent?
Common mistake: treating every lead as permanently marketable.
3. Ads and Retargeting
Check:
- Are pixels or ad platforms receiving identifiable user behavior?
- Are audiences built from customer lists?
- Are lookalike or remarketing audiences using personal data?
Common mistake: assuming "the ad platform handles it" means your company has no DPDP responsibility.
4. Website Analytics
Check:
- Which tools run on the site?
- Are IP address, device identifiers, session IDs or form fields being captured?
- Is analytics used only for measurement, or also for profiling and targeting?
Common mistake: installing tools first and asking privacy questions later.
5. Vendor List
Make a quick list:
- CRM
- Email platform
- WhatsApp provider
- Analytics
- Ad pixels
- Form tool
- Landing page builder
- Webinar tool
For each vendor, answer: what data goes there, why, who can access it and how deletion works.
6. This Week's Action
Map one campaign from first click to final follow-up. Mark every place personal data is collected, enriched, shared, uploaded or used for targeting.
If your team cannot answer where the data came from and where it goes next, start with a data flow map before rewriting policy copy.

Workforce Onboarding and Identity Checks
Construction technology platforms digitize labor management by collecting Aadhaar numbers, bank details, and biometrics. These platforms often use facial recognition to prevent proxy attendance at project sites. You must provide privacy notices in the regional languages spoken by the laborers. Since labor is transient, your system must track which contractor originally provided the worker data and for which project site the consent was granted.
Real-Time Site Tracking and Safety
Safety features in construction tech often rely on GPS tracking and geofencing for equipment operators and site workers. This location data is personal data. You must limit tracking to active shift hours within the site boundary. Collecting location history after a worker leaves the site fence exceeds the purpose of safety and site management. Our four-week gap assessment identifies where your app may be over-collecting background location data.
Contractor Data Flows and Retention
Data frequently moves between developers, general contractors, and labor subcontractors. Your platform acts as the central hub for these flows. You must ensure that developers cannot access sensitive worker details, like home addresses or bank info, unless it is necessary for direct payroll. Implementation of these access controls typically takes two to three months to ensure site operations are not disrupted.
Construction Data Risk Mapping
| Workflow Area | Personal Data Involved | DPDP Risk Level |
|---|---|---|
| Site Access | Biometrics, Face ID, Aadhaar | Very High |
| Payroll & EPF | Bank details, PAN, Mobile numbers | High |
| Safety Monitoring | Real-time GPS, Geofence logs | Medium |
| Contractor Portal | Subcontractor contact details | Medium |
| Training/Certificates | Skill levels, ID photos | Low |
This week
Review the worker onboarding module in your application. Ensure the privacy notice is displayed in the three most common languages used by your site workforce and includes a clear list of every contractor who will see their identity data.
Need help applying this to your business? Review the consulting scope and bring the systems, teams, and data flows involved to your first call. If you already have a gap assessment, see implementation support.
Frequently asked questions
Can we use facial recognition for site attendance?
Yes, but you must obtain explicit consent before capturing biometric templates. The notice must explain where the data is stored and who has access to the authentication logs.
Do we need to delete worker data once a project ends?
You must delete personal data when the specific purpose of the project or payroll cycle is complete. If labor laws require record-keeping, you may retain data only for that specific legal duration.
Are we responsible for how subcontractors use worker data?
Yes, as a Data Fiduciary, you must ensure subcontractors only use the data for the assigned site work. You need a data processing agreement to prevent them from using worker info for other projects.
