They don't appear to set any

They don't appear to set any cookies or pass the search results through their own redirect url to track what you click on. Startpage doesn't serve content from other domains in its pages either, so only they see what you do on their site.

Startpage doesn't claim to protect you from malware, they only claim not to log your IP address. There's no way to verify whether or not they log it.

You don't pass all your traffic through Startpage though, so at worst they're recording your HTTP requests to them. That's not a big deal.
