Does Cloudflare log and/or sell the data of the https traffic it decrypts?

Recently, I've been bothered by cloudflare decrypting https requests to websites which use their services (as is necessary for these services to function). I have read cloudflare's privacy policy and my understanding is that they don't sell or share this data to third parties, but the policy doesn't state if the information is logged or for how long if so.
