Meal photos: If you upload meal photos, we use them to provide photo-based features and to improve the Services (including machine learning). If you delete your account, we delete "Identifiable Meal Photos" associated with your account within the same timelines described below for account deletion, subject to limited legal, security, and operational exceptions. We may retain "Non-Identifiable Meal Photos" (and/or de-identified, aggregated, or derived versions of meal-photo data) for training and product improvement to the extent permitted by applicable law.
