It's not hard to run your own Electrum server and point your wallet to just use it. This restores Electrum to the point where it has the same privacy and security attributes as the full node, where no one else can see the address or transaction that the wallet is interested in. Electrum then becomes an all-node wallet.
Send the coin to another wallet for long-term bitcoin storage. There should be a full node behind the wallet, such as the Electrum node pointing to your own Electrum server.
Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum Wallet is fast and has few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers.

It was the first time I had imported my brain wallet private key into Armory, and I had completed a 1BTC transfer and was trying to delete the Armory wallet with my brain wallet private key, but I didn't know how I felt I should point to see if the balance under my brain wallet address was correct. This view scared me to death: I found that the BTC balance on the address of my imported brain wallet was zero! The wallet address there is an address marked Change, the balance is exactly what my wallet address should have. Instantly I petrified: I just turned 1BTC out, how could it transfer the remaining BTC from my brain wallet to a new address in Amory's wallet without my consent? If I had just deleted all the Armory Money package files, wouldn't my BTC have been lost? It's dangerous.
