FAQ

Who sees my weight?

You control whether or not other players see your weight. By default your weight is private, but you can change this in your account settings.

Who will see my photos?

Your weigh-in photos are used solely by our DietBet Referees to confirm your weight. We will not use these photos for purposes other than weigh-in review without your permission.

How do you keep the game fair?

Our Referees review all weigh-ins. We also use algorithms to detect unusual activity within and across games. At times we may require players to submit extra proof of their weight loss using a video weigh-in.
