Private PDF scanner without cloud uploads (Android)

Scanner apps see your most sensitive paper: IDs, contracts, bills and medical letters. Before you pick one, it helps to know exactly where those scans go. This page lists what to check and how NEXO handles each point.

Five questions to ask any scanner app

Do I need an account? An account usually means your files live on someone's server.
Where is text recognition (OCR) done? On the phone, or on a server?
Are my files backed up to a cloud? Convenient, but it means copies exist elsewhere.
What does the app send over the internet? Ads, analytics and downloads are normal, but they should be explained.
Can other apps see my files? Files in a shared folder are visible to other apps.

How NEXO answers

No account. There is no sign-up and no login.
On the phone. NEXO does its work on your device and runs no servers that receive your documents, scans, extracted text or chats. Scanning, search, chat, reminders and PDF tools work in airplane mode.
Not in cloud backups. Your documents live in the app's private storage, which Android encrypts, and are excluded from Android cloud backups.
Locked from other apps. Other apps and USB file transfer can't see or copy them.
App lock. You can lock the app with fingerprint, face or screen lock.
Privacy Dashboard. It shows on live data what NEXO can access, the space used and permission checks.

What NEXO does use the internet for

None of these upload your documents:

Ads from Google AdMob on the free plan, which may collect device information for advertising. Where the law requires it, NEXO asks for consent first.
Subscriptions, handled entirely by Google Play. NEXO never sees your payment details.
Downloading translation and text-recognition models the first time you use a feature.
Web pages you open, which load directly from those sites, and printing to the printer you choose.

The trade-off

Because nothing is backed up to a cloud, export copies of important documents you can't afford to lose. NEXO is an Android app; an iPhone version is coming soon, so there is no cross-device sync.
