Why? Most people shop online from around the world. You are not doing anything illegal, unethical, or that would need to be hidden. Other than not showing most of the actual trust contents to most outside parties, the fact of setting the trust up and having a trust is no secret. After all, if you're going to bank with it, you make its existence known to the IRS, to get an EIN. (Or for those in other countries, the equivalent business identification number from your tax agency).
The IRS (or tax agency in your country) will have the trust name, your name, your Social Security Number (if you are going to be the trustee and signatory), and other pertinent details. Randall will provide the directions and instructions for you to make the application. It only takes a few minutes to get the EIN. The EIN is "for banking purposes only", NOT for filing tax returns. The IRS will never ask you for a tax return on the trust. So don't volunteer it.
So if the IRS knows all about your trust, who else would you wish to hide your communications about it from? Do you think the National Security Agency will be listening to the phone calls or intercepting your emails? Who cares? Let them listen! It may bore them to death. There is absolutely nothing of any great interest to them in your getting involved with this.
