This Privacy Notice informs you of important information about how Pulmonx Corporation (“Pulmonx” or “Company”) processes data, including personal data, that we collect through the portal hosted at and associated web pages (the “Website”) and the StratX® Lung Analysis Platform made available therein (collectively, the “Platform”). Please read this Privacy Notice carefully to understand our policies and practices regarding your information and how we will treat it. The StratX® Terms of Service, including definitions of certain capitalized terms, are available online at (“Terms”).

StratX® is a cloud-based quantitative computed tomography (“CT”) analysis service that supports patient selection and treatment targeting using Pulmonx products by providing information on emphysema destruction, fissure completeness, lobar volumes and procedural success based on post-treatment scans. The Platform allows Pulmonx Customers to upload fully de-identified lung CT scans for patients that it wishes to be assessed for potential use of the Zephyr Valve or other Pulmonx products, or for post-implantation revisions (“Scans”). Pulmonx then generates a report, including associated data and information, unique to that Scan which may contain tabulated data on fissure completeness by lobe, destruction score by lobe, inspiratory lobar volume by lobe and valve occlusion status by airway (the “Report”). Pulmonx makes StratX® available to regular Pulmonx Customers.
