Privacy policy
Last updated 16 October 2026
Brain O Vision Solutions India Pvt. Ltd. ("Drisyon", "we") runs drisyon.com and its program pages. This policy explains what personal data we collect when you contact us, enquire about or enrol in a program, and how we use it, in line with the Digital Personal Data Protection Act, 2023.
What we collect
| Data | Why |
|---|---|
| Name, email, mobile number | To reply to enquiries, reserve your seat, send receipts and schedules, and call you for the technical screen |
| Company name and GSTIN (optional) | To issue a GST invoice to your employer |
| Payment ID, order ID, amount, payment status | To confirm your payment, process refunds and keep tax records |
| Technical screen notes and lab progress | To place you in the cohort and support your learning |
We do not receive your card, UPI or bank details. Razorpay handles them under its own privacy policy.
Who processes it

- Supabase: the database that records enrolments.
- Hostinger: the mailbox that receives website enquiries.

We do not sell your data or share it for advertising. We share it with lab partners or certification vendors only when you need an account on their platform, and only the minimum needed for that account.

We keep enrolment and payment records for 8 years to meet tax and accounting law. We delete screen notes and lab-progress data 12 months after your cohort ends unless you ask us to keep them for a reference.

You can ask us to access, correct or erase your personal data, withdraw consent for future use, or nominate someone to act for you. Records we must keep by law are retained until the legal period ends. Email reachus@drisyon.com with the subject "Data request"; we respond within 30 days.
