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 DPDP Guide for Stock Brokers, 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.

Balancing SEBI Rules and DPDP
Stock brokers must reconcile strict SEBI record-keeping rules with DPDP privacy mandates. SEBI requires brokers to store KYC and trade data for at least eight years. DPDP generally requires data deletion once the purpose is served. For brokers, the “purpose” includes meeting these statutory retention periods. You must document these legal overlaps in your privacy policy to justify holding data after a client closes their demat account.
Biometric and Location Tracking in Trading Apps
Mobile trading apps collect device IDs, IP addresses, and geolocation to prevent fraud and unauthorized logins. These are personal data points under DPDP. If your app uses fingerprint or face recognition for login, your privacy notice must state how this data is handled. Most apps use device-level biometrics where the broker never sees the actual print, but you must still clarify this to the user to meet notice requirements.
Third-Party Data Flows
Brokers share data with Depository Participants, Clearing Corporations, and Exchanges as part of the core trading workflow. These transfers are usually protected as legal obligations. However, many brokers also share lead data with third-party vendors for stock tips or loan offers. This specific type of sharing requires a clear opt-in. You cannot bundle this marketing consent with the mandatory terms for opening a demat account.
Data Processing in Brokerage Operations
| Workflow Area | Personal Data Involved | DPDP Risk Level |
|---|---|---|
| Client Onboarding | PAN, Aadhaar, Bank Statements | High |
| App Security | IP Address, Geolocation, Device ID | Medium |
| Portfolio Management | Holdings, Dividend history, Nominees | High |
| Support Operations | Call recordings, Registered email | Medium |
| Marketing | Trade frequency, Risk profiles | High |
This week
Review your account opening form (AOF) and digital onboarding flow. Identify if the consent for “marketing communications” is bundled into the same checkbox as “terms and conditions.” Separate these into two distinct choices so users can open an account without being forced to receive marketing calls.
Now think about your work. Where does personal data enter your workflows? Where does it sit? Who else touches it?
Frequently asked questions
Does SEBI retention law override DPDP deletion rules?
Yes. DPDP allows data retention if required by another law. Since SEBI mandates keeping records for several years, you do not have to delete them immediately upon account closure.
Can I use client trade history to market insurance or loans?
Only if you obtained specific, separate consent for cross-selling. DPDP requires that consent for trading services remains distinct from consent for marketing third-party products.
How do I handle the personal data of nominees?
Nominees are data principals under DPDP. You must ensure your account opening forms include a declaration that the primary account holder has permission to share the nominee's details.
