Privacy policy

Last updated: 18 July 2026

Your files

Every file you open here — and everything derived from it: filters, edits, statistics, exports — is processed entirely on your device, inside your browser. Files are never uploaded, transmitted, stored or seen by us or anyone else. This is an architectural property of the site — it is static and has no upload endpoint — not a policy promise. You can verify it with your browser’s Network tab, or by using the tool with your internet disconnected.

What stays on your device

Nothing you open is persisted by us anywhere. The file is read in place; any working data lives in the page’s memory and is gone when you close the tab. Exports are generated in your browser and saved wherever you choose. If you install the site as an app (or your browser caches it for offline use), that cache contains the tool’s own files, never your data.

What we do collect

Aggregate, cookieless page-view analytics (via Cloudflare Web Analytics) — the kind that says “the large-file page was viewed N times”, with no cookies, no fingerprinting, no cross-site tracking and no profile of you. Our hosting provider (Cloudflare) additionally processes standard technical request data — IP address, user agent — to serve and secure the site, as any web host does.

What we don’t do

• No accounts, no email collection, no newsletters.
• No cookies set by us.
• No selling, sharing or brokering of any data — we have nothing to sell.

Advertising

The site currently shows no ads. If we introduce ads in the future to cover costs, this policy will be updated first, any legally required consent mechanism will be added, and one thing will not change: ads run on the page, not in the tool — your files stay on your device regardless.
