I don't have any particular trust in them. However, they've staked their entire business model on privacy. That would be foolish if their intent is to sell user info, because doing that is unlikely to stay private for long.

I’m already sending my search query to DDG for them to give me search results. They don’t ask for any additional data. They just allow advertisers to bid on the first few results for a particular topic.
I’m ok with that.
