From the developer:
Monero is a secure, private, untraceable currency. Monero uses a cryptographically sound system that allows you to send and receive funds without your transactions being publicly visible on the blockchain (the distributed ledger of transactions). This ensures that your purchases, receipts, and other transfers remain private by default.
