What it reads
- Which Polymarket page is open, so it knows which market to look up. It runs on Polymarket pages and nowhere else — it is not loaded on any other site.
- Our own API, which is where every figure it draws comes from.
- Your settings, kept in your own browser: the side and size you last used, the panel language, and any watch you have set.
What it does not do
PolySmarter is analytics only. It does not sign transactions, hold or transmit funds, or place, route, change or cancel an order. It cannot read your Polymarket account, your balance, your positions or your trading history — it has no way to see any of them. Nothing it shows is a probability forecast, a trading signal, or investment, financial, legal or tax advice, and every figure describes public data that already exists. What this is, and what it is not.
