8. Children's Privacy

The Service is not intended for, or directed at, individuals under the age of 18. We do not knowingly collect personal information from children. If we learn that we have collected personal information from a child under 18, we will take steps to delete that information.

9. International Users

If you are accessing the Service from outside the United States, please be aware that your information may be transferred to, stored, and processed in the United States, where our servers and service providers are located.
