Offline scanning: the strongest privacy statement a tool can make

Privacy claims are cheap; capabilities are evidence. A scanner that completes its whole job with the network off is demonstrating where processing happens — no policy-reading required.

Why offline implies private

Uploading requires a connection. If cropping, enhancement, naming and PDF export all succeed in airplane mode, then none of those steps depends on a server — your document's bits stayed on the device because they had nowhere else to go. It's physics, not promises.

Try it (60 seconds)

1. Visit ToPDF once online (the engine caches).
2. Airplane mode ON.
3. Scan any page, name it, download the PDF.
4. Everything worked? You just verified the architecture.

When offline also just… helps

• Basements, flights, rural signal holes — paperwork doesn't wait for bars.
• Metered data: scanning costs zero bytes after the first visit.
• Sketchy public Wi-Fi: don't trust it? Don't use it — scan offline and share later from a network you trust.

Frequently asked questions

Do file-name suggestions work offline too?

Yes — the text-recognition models are part of the cached engine. The entire feature set is local.

Is anything queued to send when I reconnect?

No. There is no telemetry queue and no deferred upload — reconnecting simply lets the site check for app updates like any website.
