Every PDF tool. None of them upload your files.

Your documents should not be someone else's compute

Every other PDF app, iLovePDF, Smallpdf, the rest, sends your documents to their servers to merge, compress, or convert them. Your bank statements, your contracts, your medical records, your ID scans: uploaded, processed in someone else's cloud, cached you do not know where.

Cartarossa does all of it on your phone. The file is read, processed, and saved on the device. Nothing is uploaded, nothing is stored on a server, and we never see your documents. It is not a promise we ask you to trust, it is how the app is built. There is no server in the loop, so there is nothing to leak.

That single decision makes the app faster, because there is no round trip to the cloud. It makes it work offline, on a plane or with no signal. And it makes it tiny, a fraction of the size of the bloated alternatives.

There is no server to leak, because there is no server.

Built for people who would rather not upload

• The privacy-aware professional. Lawyers, accountants, doctors, founders. People who merge and send contracts, statements, and scans every day, and would rather those documents never touched a stranger's cloud.
• The everyday organizer. Combine receipts, split a scanned packet, compress a too-big PDF to email it, sign a form. The common tools, without ads, account walls, or a 200 MB install.
• The offline user. Travelers, commuters, anyone on bad wifi. Cloud PDF tools fail when the connection does. An on-device tool does not.

One price. Everything. Forever.

Cartarossa is free to download, and the free tier is genuinely useful, not a crippled demo. Compress, merge, split, sign, and ten more tools, all uncapped, with no watermark on your output and no daily limit.

If you want the full toolkit, there is one option, and you pay for it once.

Privacy by construction, stated plainly

Your documents never leave your phone. Every tool runs on the device. No file is ever uploaded, and we never see, store, or process your PDFs on any server.

No account, ever. There is nothing to sign up for. Open the app and use it. Premium is tied to your App Store or Google Play purchase, not to a login.

What we do collect: anonymous, aggregate usage and crash diagnostics, used only to fix bugs and improve the app, never the contents of your files. No advertising identifiers, no cross-app tracking. The full detail is in the privacy policy and in the app's Settings.

Questions

Do my files get uploaded to a server?

No. Every tool runs on your device. Your PDFs are read, processed, and saved on the phone itself, never uploaded, never stored in any cloud. We never see them.

Is Cartarossa free?

The core is free and uncapped: compress, merge, split, sign, and ten more tools. A one-time USD 14.99 purchase unlocks the premium tools like organize, protect, fill forms, and watermark.

Is there a subscription?

No. Premium is a single one-time purchase, yours forever. No monthly fee, no annual renewal.

Does compression really work without uploading?

Yes. A 19 MB scan can drop to under 1 MB with the text still sharp, and the file never leaves your phone to do it.

Does it work offline?

Completely. Because everything is processed locally, every tool works with no connection at all.

What does Cartarossa collect?

Never your documents. Only anonymous, aggregate usage and crash diagnostics, used to fix bugs. No account, no ad identifiers, no cross-app tracking.
