SignalX uses AI to summarize, compare, and group news. We, the makers of SignalX, do not collect, receive, or store any information about you. There is no SignalX server, no account, and no analytics.
How SignalX uses AI
Summaries, source comparisons, search overviews, and story grouping are generated by an AI model. AI output can be incomplete or wrong. Always check the original article before relying on it; every summary links back to its sources.
When you use an AI feature, SignalX sends only what that request needs: headlines, short snippets, article excerpts (if full-article reading is on), your search query for search overviews, and, if you use Personalize, the interests you type. It never sends your browsing history, your open tabs, or personal details.
Background research runs only when you click it. Your AI provider searches the web for the story's headline and sources, and that provider's search terms apply. The result is held briefly in memory and never saved to disk.
Where that content goes depends on the AI you pick in Settings:
- Chrome's built-in AI (Gemini Nano): runs on your device. Nothing leaves your computer.
- Ollama: runs on a machine you control. Content goes only to that machine.
- Anthropic, OpenAI, Google Gemini, or OpenRouter: content is sent directly from your browser to that provider using your own key. That provider's privacy terms apply to those requests.
What we collect
Nothing. SignalX has no backend server and no analytics, advertising trackers, or fingerprinting. We never see what you read or search, and we never sell or share data, because we never have it.
What stays on your device
So the extension works, a few things are saved locally in Chrome storage on your device only. They are not synced across devices and are not sent to us:
- Your settings: country, language, theme, followed topics, and spending cap.
- Your AI key, encrypted.
- Bookmarks, folders, custom feeds, and thumbs up/down feedback.
- Temporary caches (headlines, summaries, article text) and a local AI-usage counter for your spending cap.
Uninstalling SignalX deletes all of it. Removing your key in Settings deletes the key immediately.
News content
Headlines are fetched directly from publishers' RSS feeds and Google News by your browser. Searches and followed topics are looked up on Google News. If you turn on full-article reading, your browser fetches the article page from the publisher. None of these requests pass through a SignalX server.
