The Curio Gears Publisher application only connects to accounts owned by Curio Gears and does not store data about other people.
If you have interacted with Curio Gears and want any data about you deleted, email curiogears@gmail.com with the subject "Data deletion request". We will delete any data related to you within 30 days and confirm by email.
To remove the app's access to an account, you can also revoke it in that platform's settings (for example, Facebook → Settings → Apps and Websites).
