Marketplace Switcher for Amazon (“the extension”) is published by ilscipio GmbH. This policy explains what the extension does and does not do with your data.
Data we collect
None. The extension does not collect, transmit, sell, or share any personal data. There are no analytics, no tracking, and no external servers operated by us. Nothing you do is sent anywhere by the extension.
Data the extension stores
The only data the extension stores is your settings — the two Amazon marketplaces you choose to switch between. These are saved using the browser’s own extension storage (storage.sync) so they can persist and, if you have it enabled, sync across your own devices through your browser vendor (Apple). This information never reaches us and contains no personal information — only your two selected store domains (for example, amazon.de and amazon.com).
How the extension works
When you activate the extension on an Amazon product page, it reads the product identifier (ASIN) from that page’s URL and navigates your tab to the equivalent product URL on your chosen marketplace. This happens entirely within your browser.
The extension requests access only to Amazon storefront domains. It does not request the “all websites” / tabs permission, cannot read or act on any non-Amazon page, and Safari will never prompt you for access on other sites.
A small helper script runs only on Amazon pages to draw the toolbar icon. It reads the page’s URL (to identify the current store and product) and your system light/dark appearance, purely to render the correct “a” and destination flag. It reads no other page content and transmits nothing externally.
Third parties
Navigating to an Amazon website is governed by Amazon’s own privacy policy. This extension is an independent utility and is not created, sponsored, or endorsed by Amazon. “Amazon” is a trademark of Amazon.com, Inc.
Changes
If this policy changes, the updated version will be posted at this address with a new “last updated” date.
