Does wallet connect charge fees?

I'm curious about Wallet Connect - a popular service that allows users to connect their cryptocurrency wallets to various decentralized applications and services. I've heard some conflicting information about whether or not it charges fees for its services. So, my question is, does Wallet Connect actually charge fees for connecting your wallet to these platforms? If so, how are these fees calculated and what are they typically used for? It would be great to have a clear understanding of the costs associated with using this service.
