Privacy.

Browser preferences

The age confirmation and chosen theme are saved in local storage when your browser allows it. Clearing site data resets these choices. When storage is unavailable, controls still work for the current session.

Search and comparison URLs

Search queries, filters and selected compound IDs can appear in the URL. They may therefore be saved in browser history, copied into shared links, or included in requests and logs handled by the hosting provider. Do not enter personal medical information into these controls.

Filtering and pair resolution happen in your browser and do not call a clinical service. Fonts are served with the site.

Analytics

The site loads Google Analytics 4 to measure aggregate traffic, such as which pages are read and roughly how visitors arrive. Google sets cookies and receives your IP address, browser and device details and the pages you visit, and processes them under Google's privacy policy. The measurement is not used for advertising or remarketing. Search queries and compound selections that appear in the URL can be included in the recorded page address, so do not enter personal medical information into the site's controls. Browser tracking-protection features, content blockers and the Google Analytics opt-out browser add-on prevent this collection.

Hosting and external sources

The host receives ordinary web requests and may retain technical logs, including network and device information. The repository cannot establish the operator's deployed retention settings. Citations open independently operated websites with their own privacy practices.

The site uses a strict origin referrer policy for external navigation. This limits external referrer information to the site origin; it does not control your browser history or the host's request logs.
