Saved pages, recent reading and checklist progress are stored in your browser’s local storage. They are not sent to a Clear Lens account or API. Clearing site data removes these records. Private browsing or storage restrictions can prevent persistence.
Search and tool inputs
Lens comparison inputs are processed in your browser and are not saved. Search text appears in the URL, so it can remain in browser history and hosting access logs. Do not enter identifying or sensitive health information into search.
Hosting and external links
The site does not include advertising trackers, analytics scripts or third-party fonts. The hosting provider may process ordinary request logs. Visiting a cited external source is subject to that website’s own privacy policy.
