For self-hosted, I’ll recommend Ollama and there’s several different models you can try out. Locally on your computer. It keeps the data in a file like history or something. I forgot, it has the ability to use the cloud for like ‘kim’ or something, but anything local afaik doesn’t send. You’ll have to use the 4 to 8b models, and usually they’re not as accurate, a few are ‘uncensored’ nevertheless. It lacks it.
I am not well versed in Duck.ai. I believe it doesn’t host all of its own instances, and sends some of the conversations off via API to OpenAI or even Claude. I wouldn’t trust it.
Proton Lumo is supposedly private. It’s decent “if you pay” I think their models are self-hosted, but again, their models do ‘web search’ which send your text to the web I believe. Brave, has it built in. It’s supposedly private, but as Duck.ai, it likely uses OpenAI models on some of the picks you make.
Even Gemini isn’t save. If you read, you’ll see it talk about ‘human reviewers’ so nothing is truly private. There was something in Canada, like a shooting. Where the team was flagged about a specific somebody, and decided not to contact law enforcement.
You cannot trust AI except local. I do mine differently. I try to only ask it certain questions and put a bunch of garbage in between. Like, I’ll make something up about myself, my age or whatever, ask something random, or whatever I need then add other garbage to it and delete.
I don’t like to recommend Reddit specifically. Look up /r/PoisonFountain/ it’s interesting. They try to find ways to poison AI’s database.

On 23andme there’s this social media thing, where you can connect to ‘relatives’ like second cousins and so on. I limited my access, only enough to see who used it. My name is just my initials, doesn’t show anything else really.
Enabling strongest privacy settings, and sharing as limited data as possible. If you do use it seems to be the best route. I still think potentially at some point they might actually get compromised and all users.
I’ll get 1 year free credit monitoring, and $10 bucks then. Most Americans are already hacked from the Public National Database thing. Social security numbers, emails, and rest of it.
