Ship Compare for eBay + Pirate Ship
Effective date: July 5, 2026
This extension is built and maintained by Items and Stuff LLC. It exists to do
one thing: show you what a shipping label would cost on Pirate Ship while you're
buying a label on eBay, and hand the shipment over if you choose.
What the extension reads
On eBay shipping-label pages only, the extension reads the details of the
shipment you're working on: package weight and dimensions, origin and destination
ZIP codes, the selected service and add-ons (signature, insurance), the eBay label
price, the order number, and the buyer's shipping address.
Where that information goes
Rate quotes: package details (weight, dimensions, ZIP codes,
service options, insured value) are sent to Pirate Ship (ship.pirateship.com) to
fetch live postage rates. No name or street address is included in rate requests.
Handoff: when you click "Open in Pirate Ship," the order
number and package details are passed to Pirate Ship so your shipment is
pre-filled there. On older label pages the buyer's address is copied to your
clipboard instead — only when you click, and it goes nowhere else.
Local storage: your panel position and pending handoff
details are stored locally in your browser and never leave your machine.
What we don't do
No data is sent to us or to any server we operate. The extension has no
backend.
No analytics, tracking, or advertising of any kind.
No data is sold, shared, or used for anything beyond the price comparison
and handoff described above.
No browsing activity is collected outside eBay label pages and
ship.pirateship.com.
Third parties
Rate requests and handoffs go to Pirate Ship, which has its own
privacy policy. This extension is
not affiliated with or endorsed by eBay Inc. or Pirate Ship.
Changes
If this policy changes, the updated version will be posted at this address with
a new effective date.
