Any additional details on how encryption and key generation scheme looks like?

Or, more importantly, how does key exchange work? You can’t really claim to be totally anonymous without explaining these details.

How does key exchange work, and does the server have copies of the keys?

You can find more info on key exchange here - https://github.com/RNCryptor/RNCryptor.

The server does not have copies.

No, you really can’t. That’s a library for symmetric cryptography. The key distribution/exchange problem cannot be solved with symmetric cryptography alone - unless you are acting as a trusted party and conveying the symmetric key - in which case you are not implementing end-to-end cryptography.
