Etsy Fee and Tariff Calculator

Privacy Policy

Last updated: August 29, 2026

The short version: the extension does not send anything anywhere.

What the extension reads

When you open an Etsy listing page, the extension reads the price and shipping shown on that page so it can calculate fees. This happens entirely inside your browser.

What the extension stores

Your inputs (tariff rate, cost of goods, shipping cost, Offsite Ads setting) are stored in your browser's local extension storage, on your device. Clearing the extension's data or removing the extension deletes them.

What the extension sends

Nothing. There is no account, no sign-in, no analytics, no telemetry, no advertising, no remote code. The extension contains no network requests at all. This is enforced by an automated check in the build that fails if one is ever added.

Third parties

No data is shared with third parties because no data leaves your device. Etsy's own pages are governed by Etsy's policies; this extension only reads what is already displayed to you.
