Short version: MarketplaceOnly collects nothing and sends nothing anywhere.

What the extension stores

Only your settings, and only in your own browser:

• Whether MarketplaceOnly is on, and which areas (Feed, Video, Groups, Gaming, Notifications) you've chosen to show.
• Whether the tray is open, whether the side tab is shown, and which settings you've already seen.
• A count of how often each hiding rule recently failed to find what it looks for. This is used only to tell you when something stops working. It contains no addresses, names, or page content.

Your settings are saved with your browser's built-in sync, so they follow you to other computers signed in to the same browser account. That sync is run by your browser (Google or Mozilla), the same way it syncs your bookmarks. MarketplaceOnly has no server of its own.

What the extension doesn't do

• No analytics, tracking, or usage statistics.
• No accounts or sign-in.
• No ads.
• No remote code. Everything the extension runs is included in the package you install.
• It doesn't read, collect, or send your messages, listings, posts, friends, or browsing history.
• It runs only on www.facebook.com and web.facebook.com, and nowhere else.

Reporting a problem

If you choose Report a problem, the extension opens a public GitHub issue form in a new tab, with these details filled in: the extension version, your browser and its version, the type of page you were on (for example "Marketplace listing"), and which hiding rules couldn't find their target. It never includes the page's address, names, or anything from the page. You can see and change everything before submitting, and nothing is sent unless you press Submit on GitHub.

Permissions, in plain language

• Storage: to save your settings.
• Redirect rules (declarativeNetRequest): to send switched-off pages, like Groups, to Marketplace. These rules run inside your browser.
• Access to facebook.com: to hide switched-off areas on Facebook pages and show the tray. No other site.
