polysenseiPrivacy Policy
Last updated: June 1, 2026
PolySensei is a free Chrome extension that adds trading edges inside Polymarket. It is non-custodial and privacy-first. We collect as little as possible. Here is exactly what happens.
What we do not collect
We never collect or store your private keys, your seed phrase, or your funds. You sign every order with your own wallet. We do not track your browsing history, and we do not sell or share your data with anyone.
What the extension reads
To show you market data, the extension reads the public Polymarket page you are on and calls public APIs (Polymarket, ESPN, CoinGecko). Your connected wallet address is used only to display your own positions and standing. This stays between your browser and those APIs.
Email (optional)
If you choose to give us your email (for the early-access list or for product updates), we use it only to email you about PolySensei. You can unsubscribe at any time. We never sell it.
Rewards
We keep track of the trading volume you route through PolySensei to award Sensei Points and show your standing. Down the line you will be able to redeem points for real gifts and rewards. To do this we store your wallet address and your points tally. Nothing more. There is no token.
Changes
If this policy changes, we will update this page. Questions? Reach us at hello@polysensei.com.
