Files, pasted text and generated results are processed in this browser. They are not uploaded to a conversion server. Engine downloads can require internet access; large operations depend on the memory and CPU available on this device.

## Processing and temporary results

Files, pasted text and generated results are processed in this browser. They are not uploaded to a conversion server. Engine downloads can require internet access; large operations depend on the memory and CPU available on this device. Results stay in this browser tab until you remove them or reload/close the page. Download anything you want to keep. Saved downloads are independent of the browser workspace.

## Google Analytics on the public website

The canonical public website uses Google Analytics 4 (G-PNZFZ75FT9) for page visits and technical browser information. Analytics can use cookies. File contents, filenames, pasted tool input, generated passwords and private result identifiers are not sent as Analytics events. Preview origins do not initialize collection.
