Privacy Policy — Kalshi Order Tool

Last updated: August 1, 2026

Kalshi Order Tool ("the extension") is an unofficial, open-source browser extension that helps you place and manage manual orders on Kalshi. This policy explains what data the extension handles and how it is used.

Data the extension handles

• Kalshi API credentials — the API key ID and RSA private key you enter. These are used solely to cryptographically sign requests to Kalshi's own API.
• App state and settings — your preferences, the dry-run virtual bankroll, and open position / take-profit / stop-loss state.

How the data is stored

• All data is stored locally in your browser using the Chrome storage APIs.
• Credentials can be kept session-only (wiped when the browser closes) or encrypted at rest (AES-GCM under a passphrase you choose, derived via PBKDF2-SHA256).
• Your private key never leaves the extension's background service worker and is never exposed to any web page.

How the data is used and shared

• Your credentials are transmitted only to Kalshi's API (external-api.kalshi.com and demo-api.kalshi.co) to authenticate your own requests.
• No data is collected, transmitted, or sold to the developer or to any third party.
• There is no analytics, tracking, advertising, or remote code.

Deleting your data

Use the Clear button in the extension's Credentials card to wipe all stored credentials and state. Removing the extension also deletes its local storage.
