Classic View for Seller Central ("the extension") is published by Selling Insider Inc ("we"). It is a Chrome extension that lets you choose whether Amazon Seller Central pages open in the classic layout or Amazon's new experience.

The short version

The extension never collects or sends your listings, orders, sales, customers or any other Seller Central page content. It looks only at Seller Central page addresses, on your computer.
It never sends your browsing activity or page addresses anywhere.
Payments are handled by ExtensionPay and Stripe. The extension only asks ExtensionPay whether your copy is unlocked.
If your team gave you a team key, the extension sends that key to Lemon Squeezy to check it. Nothing else is sent.

What the extension stores on your device

Your Classic/New choice for each Seller Central section, and whether the extension is on. If you use Chrome sync, Chrome syncs these across your signed-in browsers.
When your free trial started, so it knows when the trial ends.
Whether your copy is unlocked, and when that was last checked.
Your ExtensionPay installation ID and, once you pay or restore a purchase, the account record ExtensionPay returns (subscription status and the email used at checkout). ExtensionPay's code saves this in Chrome storage, so Chrome sync may copy it to your other signed-in browsers. It is only ever sent back to extensionpay.com.
If you entered a team key: the key, the seat ID Lemon Squeezy assigned to this computer, the plan name and seat count, and when it was last checked. Never the buyer's name or email.
Whether your settings were applied successfully, so the settings page can show its status.

Payments and license checks

The extension is free for one day after install, then requires a monthly subscription ($9.99) to keep working. Purchases are processed by ExtensionPay (extensionpay.com) using Stripe.

When you buy or restore a purchase, you enter your email and payment details on ExtensionPay's and Stripe's pages, not in the extension. Their privacy policies apply to that information: ExtensionPay's policy (linked from extensionpay.com) and Stripe's privacy policy.
To check whether your copy is unlocked, the extension contacts extensionpay.com with an anonymous identifier that ExtensionPay generates for your installation. No Seller Central data, page addresses or browsing activity is included.
The extension never sees or stores your card details.

Team keys (Lemon Squeezy)

Teams can buy seats from Lemon Squeezy (lemonsqueezy.com), as a monthly subscription priced per seat. Lemon Squeezy processes the payment and issues one key for the team. This only applies if you choose to enter a team key.

When you enter a team key, Chrome first asks your permission for the extension to contact api.lemonsqueezy.com. The extension then sends the key and an anonymous label for this computer (for example "Classic View seat 3f9a") to Lemon Squeezy's License API to use one seat.
About once a day it sends the key and this computer's seat ID to confirm the seat is still valid.
When you free a seat, it sends the key and seat ID so the seat can be reused.
Lemon Squeezy's replies include details of the order that bought the key, including the buyer's name and email. The extension ignores them: it never stores, shows or sends them anywhere. It keeps only the plan name and seat count.
No Seller Central data, page addresses or browsing activity is included. Lemon Squeezy's privacy policy applies to the purchase.

How the layout switching works

The extension uses Chrome's declarativeNetRequest API to adjust Seller Central page addresses, for example by adding Amazon's own classic-layout setting to the address, or by sending a redesigned page to its previous-version address. Chrome applies these rules inside the browser. The extension never reads the contents of any page.

When you open the toolbar popup, the extension reads the address of the current tab, on your device only, to show which Seller Central section you're on. In the background it also notices when a Seller Central tab keeps bouncing between the same addresses, so it can pause itself on that tab. Addresses are kept in memory for a few seconds at most and are never stored or transmitted.

Permissions

declarativeNetRequestWithHostAccess: applies the address rules described above, on Seller Central only.
storage: saves your settings, trial start, unlock status and, if you entered one, your team key.
alarms: switches the extension off at the exact moment a free trial ends, and re-checks your subscription or team seat every few hours.
Access to Seller Central domains: limits the rules to Seller Central, and lets the toolbar button show which section the current tab is on. The extension does not access any other site, except extensionpay.com for purchases and license checks.
Optional access to api.lemonsqueezy.com: requested only when you enter a team key, and used only to check, activate and free team seats as described above.

The extension does not sell or share any data, does not use data for advertising, and does not use data for anything other than the features described here.

Changes

If this policy changes, the updated version will be published at this address with a new date.
