Unless otherwise disclosed during collection and with parent or guardian consent (for instance, in some of the educational areas on our Sites), Sierra Club does not knowingly collect personal identifiable information from children under 13 years of age. If you are under 13 years of age you should not provide personally identifiable information to the Sierra Club without providing us with consent from your parents. If the Sierra Club discovers that a child under the age of 13 has provided the Sierra Club with personally identifiable information and we do not have parental consent, the Sierra Club will immediately delete that child’s information from the Sites.</p> <p> <strong>
