On connect, your secret becomes a non-extractable signing key inside this browser and the raw
secret is discarded: nothing readable is stored anywhere, and no script can export it. Kosmos's
server forwards only GET requests carrying the signature; a signature is bound to one read-only
path for 30 seconds and cannot place an order. Want zero third parties? Run the local tool:
POLYUS_KEY_ID=… POLYUS_SECRET_KEY=… node server.mjs. Keys are minted at polymarket.us/developer.

Exact
Realized P/L is the venue's own number, taken per fill and per settlement from /v1/portfolio/activities. Cost basis and per-market realized figures come from /v1/portfolio/positions. Nothing here re-derives what the exchange already states.
Derived
Open positions are marked at the public best-bid/offer mid from gateway.polymarket.us, so unrealized P/L moves with the book, not with an official settlement mark. The account-value history accrues one snapshot per visit into this browser's local storage. The venue publishes no equity history, so this page refuses to invent one.
Local by design
Connected keys live in this browser as non-extractable WebCrypto material; the raw secret is discarded on connect and cannot be read back by any script. Kosmos forwards only signed GET requests to three read-only api.polymarket.us endpoints; signatures are path-bound, so they cannot trade. The fully local version involves no third party at all. Keys are minted at polymarket.us/developer. Not affiliated with Polymarket.
