India's First LMS Where You Own the Payments

Most LMS platforms act as the payment middleman and take a cut. CyphexClassrooms doesn't — you connect your own gateway and collect directly.

Your Account. Your Money.

Each institution connects their own Razorpay, PayU, or Cashfree account. Student payments go directly into your bank — CyphexClassrooms never handles your money.

Zero Commission. Zero Cut.

We charge only a flat platform subscription fee. No percentage cut on transactions, no hidden fees, no revenue sharing — 100% of every payment is yours.

Link in Under 2 Minutes

Open your gateway dashboard → copy your API Key & Secret → paste into CyphexClassrooms settings → click Test Connection → done. No developer needed.
