Smart Printer (Android app com.lam2000.printer, iOS, iPadOS and macOS app com.lam2000.printer, and the Windows app) is made by Lam Nguyen Developer ("we").
Effective date: October 25, 2026
This policy explains what data the app uses, what leaves your device, and who receives it. In short:
The photos, documents, scans, web pages and labels you print are processed on your device and sent straight to the printer you choose, over your local network, Bluetooth or USB. They never pass through our servers — we run none — and we never receive them.
The app has no accounts and never asks for your name, email address or phone number.
On Android and iOS the free version shows ads from Google AdMob. AdMob collects the data listed below. Smart Printer Pro removes the ads.
Device or other IDs (advertising ID): collected and shared with Google by AdMob, for advertising, analytics and fraud prevention.
Approximate location (from your IP address): collected by AdMob, for advertising and fraud prevention.
App interactions and diagnostics (ad views, clicks, performance): collected by AdMob, for advertising, analytics and fraud prevention.
Purchase history: handled by Google Play or the App Store when you buy Smart Printer Pro. We never see your payment details.
All of it is encrypted in transit. Nothing else leaves your device. Details follow.
You choose what to print: photos, documents (PDF, Word, Excel, PowerPoint, text and more), camera scans, web pages, text, templates, labels, contacts and email attachments. The app turns them into pages on your device and sends them directly to the printer you pick:
Wi-Fi and network printers: over your local network (IPP / AirPrint / the system print service). The app looks for printers on your network with mDNS/Bonjour.
Thermal, receipt and label printers: over Bluetooth, USB or your local network.
The system print dialog, when you choose it.
Web pages you print are downloaded from the site you enter, directly by your device. Files from cloud drives are picked through the system file picker; Smart Printer never signs in to your cloud accounts.
Your print history, recent files, saved printers and settings are stored only on your device. Uninstalling the app deletes them; you can also clear the history in the app.
Camera: to scan documents and take ID photos. Pictures stay on your device.
Photos and files: only the items you pick are read.
Contacts: only when you print a contact card; the contact you pick is read on your device and never sent anywhere.
Bluetooth and location (Android 11 and older need location permission for Bluetooth scanning): to find and connect to nearby Bluetooth printers. The app does not use or store your location.
Local network: to find and print to printers on your Wi-Fi.
Notifications: to show print progress and results.
Text recognition (OCR), face detection for ID photos and background removal run on your device: Google ML Kit through Google Play services on Android, Apple Vision on iOS, iPadOS and macOS, and Windows' built-in OCR. Your images are not sent to us or to Google for these features.
The free version on Android and iOS shows ads from Google AdMob (Google LLC). AdMob uses the advertising ID, IP address and information about ad interactions to show and measure ads and to prevent fraud. Where the law requires it (for example in the EEA, the UK and Switzerland) the app asks for your consent with Google's consent form before personalised ads are shown; you can change your choice at any time in Settings ▸ Ad privacy. You can also reset or delete your advertising ID in your device settings.

Smart Printer Pro is sold through Google Play and the App Store. The store handles the payment; the app only learns which plan is active, and keeps that on your device to unlock Pro features. Manage or cancel a subscription in your Google Play or App Store account.
We do not sell your data and we do not share it with anyone except Google through AdMob as described above.
Smart Printer is not directed at children under 13 and we do not knowingly collect data from them.
Everything the app stores stays on your device and is deleted when you uninstall the app. Data that AdMob collects is kept by Google according to Google's privacy policy.
Turn off personalised ads in Settings ▸ Ad privacy (where available) or in your device's ad settings.
Deny or revoke any permission in your device settings; only the feature that needs it stops working.
Delete your print history in the app, or uninstall the app to delete everything.
We will update this page when the app's data practices change, and change the effective date above.
