Privacy policy

PolyFeed has no accounts, no ads, no analytics and no tracking. One thing leaves your browser: which Polymarket page you are on.

Last updated August 2, 2026.

What is sent off your device

• The URL of the Polymarket page you are viewing. The panel sends it to the PolyFeed news server (/v1/resolve) so it can tell which market to show news for. The extension runs only on polymarket.com, so no other browsing is ever seen. The URL is used to answer the request and is not written to the database or tied to any identity.
• Requests for the news feed itself — the panel fetches scored stories and subscribes to a live update stream. These carry no information about you.
• Source favicons. Small site icons next to each headline are loaded from Google's public favicon service, which means Google sees the domain of the news sources displayed in your panel. No PolyFeed data or identifier is attached.

What is stored on your device

Panel preferences only, in Chrome's local extension storage: whether the panel is collapsed, the "market-moving only" filter, and the address of the news server. Clearing the extension's data resets them. Nothing is synced.

What is never collected

• Names, emails or any personally identifying information
• Wallet addresses, balances, positions, orders or authentication data
• Browsing outside polymarket.com, keystrokes, clicks, or page content
• Cookies or advertising identifiers — PolyFeed sets none

Server logs

The news server is hosted on Railway. As with any web host, its infrastructure keeps short-lived operational logs that can include the requesting IP address and request line. They are used only to keep the service running and are not analysed, profiled or shared.

Sharing

Nothing is sold, rented or transferred to third parties. Nothing is used for purposes unrelated to the panel's single purpose, and nothing is used to determine creditworthiness or for lending.

Children

PolyFeed is not directed at children under 13 and collects no information from them.
