• Sending critical transaction updates, OTPs, renewal notices, and billing receipts.

6. Third-Party Payment Gateways

All financial payments on Calcuin are processed through encrypted, PCI-DSS certified payment gateways (e.g. Razorpay / UPI).

Calcuin does not store or touch your credit card numbers, CVVs, net banking credentials, or UPI PINs.

7. Legal & Compliance Disclosures

We may disclose account registration details if required to do so by applicable laws, legal processes, valid government subpoenas, or law enforcement inquiries to protect against fraud, illegal software piracy, or legal liability.

8. Data Security & Encryption

We implement robust security measures, including SSL/TLS encryption for web traffic, password hashing (bcrypt), and hardware signature verification to protect your account against unauthorized access.

You maintain total ownership of your data. You can:

• Export your entire financial ledger to Excel or PDF format at any time.
