When you are done paying for your order, we receive an email copy of your invoice (the pack slip) from weebly.com (our web site creation tool and host). Then we use GoShippo.com to purchase your shipping label. Last, we pack your order, print your shipping label and send your order out with the mail.
What I am saying is: all we use your information for is to complete your order. If you need to know what the other companies do, please read their policy. All the companies involved (that I am aware of) are: Weebly.com, GoShippo.com, PayPal.com and USPS (United States Post Office).
