Ironically, your data is safe if the only sites you use are Google, Facebook, Amazon, etc which have their own CDNs.
Realistically, what percentage of the human population uses at least one service "protected" by CloudFlare? I'd think it'd be safe to say at least 50%.

Uber uses Cloudflare servers behind the scenes, even if you access it through the app. Lots of companies do this.
1Password also uses Cloudflare.
