For the best possible experience, Playfire requires that your Steam profile is set to public. This will allow Playfire to display all your gaming achievements, gaming library, and all associated bragging rights - the lifeblood of the Playfire community. Playfire also requires this information so we can correctly award you for any of the Playfire Rewards you are eligible to receive.
Playfire users who have not set their Steam accounts to Public will unfortunately not be able to participate in Playfire Rewards.
To update your Steam privacy settings, please follow the instructions provided by Steam on their knowledge base: https://support.steampowered.com/kb_article.php?ref=4113-YUDH-6401
