CLEAR DATA BOUNDARIES

Local tools and online AI are not the same.

Web tools do not upload documents. Core Android PDF tools also process documents on-device. Android’s Online AI is optional and off until enabled. When used, selected PDF text or scanned page images are sent over HTTPS through the ZoriaPDF API to Z.ai. ZoriaPDF servers do not store this content; the provider’s privacy policy applies. Chrome’s supported PDF and image tools process files locally.
