About OfflyPDF

One developer. Zero cloud.

I got tired of PDF apps that upload a private document to a stranger's server just to remove a page or add a signature. So I built one that never leaves your phone.

Why I built it

The problem

Most PDF apps are a website in disguise

Compressing a payslip, signing a lease, merging bank statements — in most apps that means uploading the document to a server you know nothing about, then trusting a privacy policy to delete it.

The decision

Remove the network entirely

OfflyPDF runs every tool on your phone's own processor. The app doesn't request the internet permission at all — so uploading your files isn't something I promise not to do, it's something the app is incapable of doing.

The result

Everything else follows from that

No accounts, no analytics, no subscription funnel, no ads. Just the tools, working the same on a plane, in a basement, or on airplane mode.

What I believe

Three rules I hold the app to. If a feature breaks one of them, it doesn't ship.

Private by default

No internet permission, no analytics, no third-party SDKs. Your files never leave your device — not even to me.

Built by one person

No investors, no growth team, no roadmap decided by a boardroom. Just one person shipping the app they wanted to use.

No dark patterns

No accounts to sign up for, no nag screens, no subscription funnels. Open the app, do the task, done.

Say hello

Questions, feedback, or just want to say hi? Every message goes straight to me — no support queue, no bots.
