Coinus Support page:
What coins/tokens can I use in Coinus Wallet?
The Coinus wallet supports Ethereum/ERC 20 tokens, EOS/Eos tokens, Bitcoin, and Raven.
Coinus further describes itself as a “decentralized wallet” and states on private keys:
CoinUs does not store private key and users are responsible for damages from loss or leakage.
This is further confirmed in the support article “Checking the Private Key”
This is evidently a self-custodial wallet, however we have been unable to locate the source code. We emailed their support on September 12, 2021 and has so far, not been able to receive a reply.
Thus our verdict is a self-custodial wallet, however it has no source code that can be verified.

Do your own research
In addition to reading our analysis, it is important to do your own checks. Before transferring any bitcoin to your wallet, look up reviews for the wallet you want to use. They should be easy to find. If they aren't, that itself is a reason to be extra careful.
