Stack Em does not contain adult content. We do not collect sensitive categories of data (such as health, financial, or precise location) for the purpose of the game.

Stack Em is not directed to children under 13. We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will delete it. If we learn that we have collected personal information from a child under 13 without verification of parental consent, we will take steps to delete that information.
