Privacy Policy

What ArticleLens processes

The only content ArticleLens reads is the text of the article on the page you explicitly summarize. Nothing is read in the background: the extension injects its reader into a page only when you press Summarize, under a permission Chrome asks you to grant.

Local by default

By default the AI model runs entirely in your browser (WebGPU). The article, the summary, and everything in between stay on your device. The model weights are downloaded once from the Hugging Face Hub and cached by your browser — that download contains no information about you or the pages you visit.

Cloud mode is opt-in

If — and only if — you choose a cloud model and provide your own API key, the article text is sent directly from your browser to the provider you picked (OpenAI, Anthropic, or OpenRouter). ArticleLens marks this explicitly in the interface. No intermediary servers are involved: we do not operate any servers, and the text never passes through us. The provider handles that data under its own privacy policy.

API keys

Your API keys are stored only in your browser's local extension storage (chrome.storage.local). They are sent exclusively to the corresponding provider as the authentication header of your own requests, and you can delete them at any time from the panel.

What we never collect

No analytics, no telemetry, no accounts, no cookies, no browsing history, no personal data. ArticleLens has no backend. The "browsing history" permission Chrome mentions is used for exactly one thing: noticing you navigated away from a summarized page, so a summary is never attributed to the wrong article.

Changes

If this policy changes, the new version is published on this page with an updated date. The source code is public, so every claim above is verifiable.
