What OddsDisplay is

OddsDisplay is a display-only browser extension. It reads probability and contract prices already visible on supported prediction-market pages and displays their American-odds equivalent alongside them.

What the extension sends, and to whom

The extension contacts exactly one service: the Everything Odds licensing server, for license activation and periodic license verification (roughly weekly). Those requests carry only:

• your license key,
• a random installation identifier the extension generates itself (a UUID — not a hardware fingerprint, serial number, or anything derived from your device), and
• the timestamps that activation/verification inherently create on our server.

It never transmits:

• prediction-market passwords or account credentials,
• wallet keys or seed phrases,
• trades, positions, or order history,
• market browsing activity or the prices you are viewing,
• banking or payment card information.

There is no analytics or telemetry in the extension. Its content scripts run only on novig.com, kalshi.com, and polymarket.us, and its browser permissions are storage (your settings and license state) and alarms (the weekly verification timer).

Settings storage

Display preferences are kept in Chrome's extension storage; if you use Chrome sync, Chrome may sync those between your own signed-in browsers. Your license key and installation identifier are stored only locally on each device.

Information the website collects

Purchases are processed by Stripe, our payment provider. Your card details go to Stripe directly and never touch our servers. From a purchase we receive and keep: your email address, payment identifiers, and the license we issue you (stored as a cryptographic hash). We use your email to send your license key (delivered through Resend, our transactional email provider), and to handle support and refunds — nothing else. The site itself sets no advertising trackers.
