INCI Scanner is a free Chrome extension that helps you understand cosmetic ingredients. This policy explains what data leaves your browser when you use it.
When you click "Check ingredients" on a product page, the extension reads two things from that page and sends them to our server for analysis: the product name and the ingredient list. No other information from the page is read or transmitted.
We do not collect your name, email address, location, browsing history, or any personally identifiable information. We do not use cookies or tracking pixels.
The ingredient text is sent to two places:
Our server — hosted on Vercel (vercel.com). It receives the ingredient list, forwards it for analysis, and returns the result to your browser. Nothing is stored or logged after your request is complete.
Anthropic's API — the analysis is powered by Claude, an AI made by Anthropic (anthropic.com). Anthropic processes the ingredient text to generate the safety breakdown you see. Anthropic's own privacy policy applies to this step and can be found at anthropic.com/privacy.
Nothing is stored on our server. Requests are processed in memory and discarded immediately after a response is sent.
If you have caching enabled in the extension, recent scan results are saved locally in your browser using Chrome's storage API (chrome.storage.local). This data never leaves your device and is only used to avoid repeat API calls for the same product.
