Every PDF tool you've used has a copy of your files. Except this one.

Here's what happens to your document when you click "merge."

Every other PDF tool
Your file leaves your device
You pick your file
Your contract, medical record, tax return — whatever it is
Sent over the internet
A server in who-knows-where now has it
You don't know the country, the company, or the laws that apply
Someone else's machine reads every page
Their system processes your document
Every word. Every signature. Every dollar amount.
You get a result back
You download the merged PDF
Great. But your original is still sitting on their server.
They promise to "delete it later"
You have zero proof it's gone
Backups, caches, logs — they can say anything. You can't verify it.
Your file is on a server you don't control. You just have to trust them.
