How to Set Up the Croissant Extension

Install and enable the Croissant extension on Chrome or Safari to build your Collection and see buyback values as you shop.

Written by Croissant Support

The Croissant extension is the easiest way to build your Collection: as you shop supported retailers, eligible items are added to your Collection automatically, and you can see an item's buyback value before you buy.

The extension is available on Chrome (desktop) and Safari (iPhone). Set up whichever you use below — you only need one to start.

Safari (iPhone)

Before you start

  1. Install the Croissant app and sign in — the mobile extension needs a Croissant account, and it's only supported on iPhone (iOS).

  2. Set Safari as your default browser: Settings → Apps → Safari.

Turn on the extension

  1. Open Safari and tap the extensions icon in the address bar.

  2. Tap Manage Extensions, then toggle Croissant on (it should turn green).

  3. When the permissions popup appears, tap Always Allow.

  4. Then tap Always Allow on Every Website.
