It’s possible to reduce the privacy issues by using API’s with a local frontend. Given that the later usually caters to companies instead of end consumers they actually have simple opt-outs for information logging.

Requires a bit of know-how, and you’ll be paying for your llm per use (not that bad actually, I’ve personally averaged <10$/yr in api costs) but at least you get to have all your personal issues on your local device instead.

For a chatGPT-like experience you probably want the ooga booga web generation ui but there’s others too.
