Our services are primarily intended for adults. If you are a minor under 14, please read this policy and use the service under guardian supervision, and submit personal information only with guardian consent. We do not knowingly collect minors' personal information; if we find we have collected it without verifiable guardian consent, we will delete it as soon as legally required.
