PolyJev

Privacy Policy · Last updated: October 28, 2026

PolyJev (“we”, “our”, or “the Service”) provides a Chrome browser extension and web application at polyjev.flyw.io that displays calibrated AI probability estimates, market research notes, and optional read-only position and watchlist alerts for Polymarket prediction market events.

1. Information We Collect

  • Account & Authentication Data: When you register or sign in on polyjev.flyw.io, we collect your email address and a hashed password (or email verification code) to issue a session token (JWT) and maintain your credit balance.
  • Active Polymarket Event Identifier: When you visit a https://polymarket.com/event/* page, the extension reads the event slug from the page URL to fetch or display cached AI probability estimates for that specific market. We do not track your general browsing history on other websites.
  • Optional Read-Only Polymarket Profile & Watchlist Data: If you use the Workspace feature to bind a public Polymarket wallet/profile address or sync your Polymarket favorites, we store the public wallet address, public position snapshots, and watchlist market identifiers to provide price-change monitoring and optional email alerts. We never request or access private keys or seed phrases.
  • Payment & Billing Records: Credit top-ups are processed through hosted third-party crypto payment invoices (NOWPayments). We store order identifiers, invoice amounts, payment status, and credit ledger entries; we do not collect or store credit card or bank account numbers.

2. How We Use Information

We use the collected information solely to operate and provide the core functionality of PolyJev:

  • Authenticating your account between the web app and the Chrome side panel;
  • Generating and caching AI probability estimates and research summaries for Polymarket events;
  • Managing your credit balance and transaction history;
  • Monitoring public market prices for your bound read-only positions or watchlist and sending optional alert emails when your configured threshold is reached.

3. Chrome Extension Permissions & Local Storage

  • sidePanel: Displays the PolyJev assistant panel alongside Polymarket event pages.
  • storage: Stores your session token, UI theme/language preference, and short-lived local cache of analysis results in chrome.storage.local.
  • alarms: Periodically syncs your bound read-only Polymarket positions and favorites in the background.
  • scripting & Host Permissions (polymarket.com, polyjev.flyw.io): Injects in-page probability badges on Polymarket event pages, reads your public Polymarket watchlist when requested, and syncs sign-in state from polyjev.flyw.io.

4. Data Sharing & Third Parties

We do not sell, rent, or trade your personal data to third parties, and we do not use your data for advertising or creditworthiness purposes.

We only share limited data with service providers strictly necessary to run the Service:

  • Polymarket Gamma / Data APIs: Public market slugs and public wallet addresses to retrieve odds and public position data.
  • AI & Search Providers (SandBase / Exa): Public market titles and descriptions to generate research summaries and probability estimates (no user personal data is sent).
  • NOWPayments: Order amounts and order IDs to process optional credit recharges.
  • SMTP Email Provider: Your email address to deliver verification codes and optional price-alert notifications you explicitly enable.

5. Data Retention & Deletion

Local extension data can be cleared at any time by signing out in the web app or uninstalling the Chrome extension. You may unbind your Polymarket wallet address or disable monitoring alerts at any time in the Workspace page. To request complete deletion of your account and associated records, contact us at the email below.
