FAQ
Frequently asked questions
What items can I track?
Any item listed on the Steam Community Market for S&Box (App ID 590830). This includes all cosmetics, outfits, hats, and other tradable items.
How often are prices updated?
Prices are fetched from the Steam Community Market. Free users get 15-minute refreshes, Premium users get 5-minute refreshes. Prices update when you view your portfolio.
Is it really free?
Yes! The free plan includes 3 portfolios, live pricing, P&L analytics, and charts. Premium ($3.99/month) adds more portfolios, faster refreshes, and removes ads.
Do you sell my data?
No. We only store your Steam ID, display name, avatar, and the portfolios you create. We don't share or sell your data. See our privacy policy for details.
Can you trade items on my behalf?
No. S&Box Tracker is a read-only portfolio tracker. We use Steam's Web API key which can only read public data — it cannot trade, sell, or modify your Steam account in any way.
How is profit/loss calculated?
Unrealized P&L compares your average buy price to the current market price. Realized P&L is calculated when you log a sell transaction — the difference between your sale price and the cost basis of the sold units.
Can I import my Steam inventory automatically?
Yes. From the dashboard, click 'Import Inventory' and pick the items you own from your Steam inventory. Set your buy prices and quantities, then import them as a new portfolio — every item becomes a logged BUY transaction automatically. No manual typing.
