ChemLookup ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains our practices regarding the collection, use, and disclosure of information through our Chrome Extension, ChemLookup.

1. Information We Do Not Collect

ChemLookup is designed to protect your privacy and operates entirely client-side.

• No Personal Data: We do not collect, store, track, or share any personally identifiable information (such as names, email addresses, or IP addresses).
• No Browsing History: We do not track, log, or store your browsing history or the websites you visit.
• No Search Queries: Your chemical search queries are processed on-the-fly to fetch data from the official PubChem API and are not saved on any external servers.

2. Third-Party API Usage

ChemLookup connects directly to the official PubChem API (provided by the National Center for Biotechnology Information - NCBI) to dynamically fetch chemical data. Your use of this extension is subject to NCBI's data usage and privacy policies. We do not transmit your data to any other third-party servers.
