How manual UPI checkout works
1. Pick one subject
Start checkout with the email address where you want your private access link.
2. Pay and submit the reference
Pay the exact amount to the UPI ID shown on the order, then submit the UPI transaction reference.
3. We check the bank credit
Support checks the incoming payment in the bank account before approving access. A UPI screenshot or transaction reference alone is not confirmation.
4. Get a private link
After approval, support sends a one-time private sign-in link to your email. Keep it private.
