NexusScore Privacy Policy

Last updated: June 29, 2026

NexusScore is a Chrome extension that displays live sports scores in a side panel and as an on-page overlay. This page explains what data the extension does — and does not — collect.

Summary

NexusScore does not collect, transmit, or sell any personal data.
It does not use analytics, trackers, or advertising of any kind.
It does not read, log, or transmit the content of any page you visit.
Your preferences (which sports/leagues you follow, starred games, layout settings) are stored only in your browser's local extension storage, on your own device, and are never sent anywhere.

What data is stored, and where

NexusScore uses Chrome's storage.local API to save two things directly on your device:

Your settings — tracked sports/leagues, starred games, layout mode (Top Ticker / Dynamic Island / hidden), and similar display preferences.
A cache of the latest live scores fetched from public sports APIs, so the side panel and overlay can render instantly without waiting on a fresh network request.

None of this data leaves your device. It is not sent to the developer, not synced to any server, and not shared with any third party.

Network requests the extension makes

To show live scores, NexusScore fetches publicly available sports data from the following services. These are read-only requests for public game/match data — no personal information, browsing history, or page content is ever sent to them.

Service	Purpose
site.api.espn.com sports.core.api.espn.com	Live scores, stats, and box scores for MLB, NBA, NFL, NHL, NCAAF, NCAAB, soccer, tennis, MMA, golf, NASCAR, IndyCar, and F1.
esports-api.lolesports.com feed.lolesports.com	Live match schedule and in-game stats for League of Legends esports.
ddragon.leagueoflegends.com	Static champion icon images.

Permissions the extension requests

Permission	Why it's needed
`storage`	Save your settings and the live-score cache locally, as described above.
`sidePanel`	Show the live-scores side panel UI.
`offscreen`	Keep a background page open to poll for live score updates — required because a service worker alone cannot hold a persistent polling loop.
`tabs`	Close the side panel on request, and find already-open tabs that need the on-page overlay injected after an install or update.
`scripting`	Inject the on-page overlay into tabs that were already open before the extension was installed or updated (new tabs receive it automatically).
Host permissions (listed above)	Fetch public live sports data from those specific domains only.

Children's privacy

NexusScore does not knowingly collect data from anyone, including children, since it does not collect personal data from any user.

Changes to this policy

If this policy ever changes, the updated version will be posted at this same URL with a revised "Last updated" date.
