Chrome extension privacy

Updated November 5, 2026 · Applies to Listwell Chrome extension version 0.3

The Listwell Chrome extension helps you save products to your Listwell account. This notice explains the extension’s behavior alongside the Listwell Privacy Policy.

What happens when you click

When you click the Listwell toolbar icon or use its keyboard shortcut, the extension displays a dashboard in a popup attached to the icon. It reads the current tab’s web address locally to show the store’s hostname. Opening the popup checks your Listwell session and loads your account totals and owned-list links; these account requests do not include the current page’s address. Product retrieval starts only when you click Get product details. Continuing an existing review may reuse a fresh temporary preview. Product retrieval is unavailable on browser settings and local pages, although the account dashboard remains available. The extension is unavailable in private browsing. URL fragments are removed.

After you explicitly request product details, Listwell receives the selected URL to retrieve a product preview. Choosing manual entry instead opens the Listwell editor with that URL prefilled. Its backend may send the URL to merchant APIs or product-information retrieval providers. Your browser may request product photos from external image hosts. These requests can reveal ordinary connection information, including your IP address, to the services receiving them.

Reviewing and saving

Sign-in takes place on the Listwell website. The extension does not receive or store your password, authentication cookies, or account tokens. The popup makes authenticated requests to Listwell using your existing website session where available. Chrome attaches the session cookie to those requests; extension code does not read its value. Access is limited to the configured Listwell API host.

In the popup you can select a list, choose a photo, and enter a size or note. Previewing alone does not create a saved item. After you confirm, Listwell stores the item and your selected details in your account under its normal retention and sharing settings. Selected product URLs and temporary previews may also be retained in service caches and operational records as described in the main Privacy Policy.

Temporary drafts

To restore your work if the popup closes, the extension temporarily stores the selected product URL and preview, your Listwell account identifier, destination list, size, note, photo selection, and save-confirmation state in Chrome’s in-memory extension session storage. These records are not synced to other browsers. Drafts are treated as expired after 15 minutes and cleaned up when the popup next checks them. Chrome also clears this storage when the browser session ends or the extension is reloaded, disabled, or uninstalled.

The next account check removes drafts belonging to another account or a signed-out session. Closing a popup during saving can leave the result uncertain; the extension asks you to check My Items before retrying.

What the extension does not do

• It does not monitor background browsing or read your browsing history.
• It does not read shopping page contents, forms, or merchant account details.
• It does not change shopping pages, replace affiliate links, or add merchant cookies.
• It does not sell user data or store authentication credentials inside the extension.

The extension’s purpose is saving products you deliberately select. Data is used to provide and operate that feature, including security and troubleshooting, subject to the main Privacy Policy.

Your choices

You choose when to invoke the extension and whether to save. Avoid submitting pages whose addresses contain private information you do not want Listwell to receive. You can uninstall the extension through Chrome’s extension settings. Uninstalling does not delete previously saved items or your Listwell account; those are managed in Listwell.
