Privacy boundary

Your document stays in this browser tab.

The selected file is read by browser JavaScript and is not uploaded.
The parser uses package paths and relationship XML needed for the image graph. It does not render or send document text.
Inspection works without analytics. On an eligible public inspection page, optional Yandex Metrica loads only after you allow it for this tab. Preview, QA, support pages and supported browser privacy signals disable it.
Our measurement sends the public page path and fixed event names for an audit start, a complete supported image-graph diagnosis, a partial result or a read error. No file name, package path, relationship ID, target, document text or result rows are included. Samples and untrusted automated submissions are excluded.
Optional analytics is not anonymous: the provider may receive IP address, browser details and cookies. Session replay, click maps and outbound-link tracking are disabled. Page URLs with a query or fragment are excluded; our explicit page-view call does not send a referrer or document-derived title.
Your allow/deny choice, QA exclusion and event deduplication markers use this tab's sessionStorage. No document content is stored there. Turn off on an inspection page to withdraw; if analytics was loaded, the page reloads to unload it. This does not erase data already received by the provider.
No lead form, account or document-processing API is installed. Hosting still receives ordinary website requests; those are separate from optional analytics and do not contain the selected document.
No output is saved automatically and the original file is never rewritten.
Closing or reloading the tab clears the in-memory result.
