⚡ HOW IT WORKS
1. Pick a tool from the home screen
2. Choose a file from your device
3. Save the result or share it — no sign-up screen in between
🔒 OFFLINE BY DESIGN
Core PDF operations run offline, on your device — not in the cloud. A file
you select is copied into private app storage only to be processed, and the
output stays on your phone until you choose to save or share it. Your
recent-files history is stored locally and can be cleared anytime in
Settings. This app doesn't use an ads SDK, and it doesn't use an analytics
or tracking SDK — your documents and file names aren't collected.
📄 SAVE & SHARE, YOUR WAY
Every tool ends with a clear result you can preview, save to your device, or
share through Android's normal share sheet — straight to email, chat, or
another app.
✍️ A HONEST NOTE ON PDF TO WORD
PDF to Word conversion works well for most documents. Very complex layouts —
heavy multi-column text, dense tables, or embedded objects — may shift
slightly when converted, since this is a conversion, not a replica.
PDFongo isn't trying to be a full document editor, a scanner, or a cloud
suite. It's a focused PDF toolbox — the handful of tools people actually
reach for — built to work without an account and without sending your files
anywhere you didn't ask them to go.
