9. Children's Privacy:
Revision History is intended for use by educators and schools, and is not intended for use by children under 18. We do not store any data related to the content of student writing. If you are under 18, you must have permission from a parent/guardian or teacher before using our service. If you are a parent or guardian and believe that your child has provided us with personal information without your consent, please contact us at info@revisionhistory.com. We take children's privacy very seriously and will take steps to remove such information from our servers promptly. We reserve the right to suspend or delete accounts that we become aware were created by users under 18 without appropriate permission.
For teachers and educational institutions using Revision History with students under 18, it is your responsibility to obtain appropriate parental consent as required by applicable laws, including the Children's Online Privacy Protection Act (COPPA) in the United States.

Our extension requires certain permissions to function properly. These permissions are used solely for the purpose of providing our document analysis service and, for Plus users, managing subscription status.

While we strive to provide accurate and reliable information, we do not guarantee the complete accuracy, reliability, or timeliness of the information provided by our extension.
