Lume is designed so that your browsing never leaves your device. This policy explains, plainly, what the extension does and does not do with your data.

What Lume does

As you browse, Lume notices pages you spend time reading and extracts a small text signal from them (the page title, headings, and meta description). It converts that text into a numerical embedding using a small open-source AI model (Xenova/all-MiniLM-L6-v2) that runs entirely inside your browser, and matches it against a public news feed to recommend related stories.

Data we collect or transmit

None. Lume does not collect, sell, share, or transmit your personal data or browsing activity to the developer or any third party.

• Page text, embeddings, your reading history, muted sites, and the recommendation ranking are stored locally in your browser (IndexedDB) and never sent anywhere.
• All embedding and matching happen on your device.
• There is no account, no sign-in, no analytics, and no tracking.

Network requests

The only outbound network requests Lume makes are:

1. News feed — periodic requests to our Cloudflare Worker (story-discovery-feed.digitalhen.workers.dev) that serves a public list of news articles. These requests contain no information about you or the pages you have read; they only fetch the public feed.
2. Model download — a one-time download of the open-source embedding model from huggingface.co (and its CDN on *.hf.co). After this download the model is cached and runs offline.

No other hosts are contacted.

Data storage and deletion

All data is stored locally on your device. You can remove it at any time using the “Clear all data” button on Lume’s Discovery page, or by removing the extension.

Permissions

Lume requests only the access it needs to work: to read the pages you view (so it can recommend related reading), to run the on-device model, and to fetch the public news feed. It does not use this access for any other purpose.

Changes

If this policy changes, the updated version will be posted here with a new date.
