Is sparrow safe?

Yes.
Use it with your own node.

Ok, then you can connect your sparrow wallet to public electrum server.
Consider running your own node later.

Even if you use one of the nodes provided by Sparrow, it’s far safer than any bank, and on par with any Bitcoin hot wallet. Since it is a hot wallet, however, just make sure you withdraw to cold storage after you mix
