- The page distinguishes document processing from telemetry, listing coarse file-size buckets and anonymous button-click events.
Field notes
The homepage describes browser-side rendering, PII detection, OCR, marking, and flattening, and says exported files have author, creation-date, and software metadata stripped. It lists 29 PII patterns, coverage for nine countries, and five OCR languages. The site also itemizes limited telemetry and hosting-provider request records, rather than claiming that no network activity occurs.
