If Coinosh were to cease operations, which is highly unlikely as the team is committed to continuous service, your funds would still be safe. This is because Coinosh is a decentralized wallet, meaning your funds and private keys are stored on your device, not on Coinosh's servers.
As long as you have your private keys or recovery phrase, you can access your funds using another wallet that supports the same blockchain. It's crucial to keep your recovery phrase safe and secure for this reason.
However, rest assured that Coinosh is dedicated to providing ongoing support and services.
