SmartPrint Hub

Privacy Policy

Effective date: October 29, 2026

Summary

• Your documents, photos, scans and signatures stay on your phone. They are sent only to the printer you choose on your local network and are never uploaded to our servers.
• You do not need an account. We do not ask for your name, email address or phone number.
• The app is free and shows ads from Google AdMob. Google AdMob and Google Firebase collect some device and usage data, described below.
• You can change your ad consent choices at any time in Settings > Privacy options.

1. Who we are

This policy explains how the SmartPrint Hub Android app ("the app", "we", "us") handles information. If you have questions, contact us at zahidraza993@gmail.com.

2. Information that stays on your device

The following is processed only on your device and is never sent to us:

• Files you print or edit. This covers documents (PDF, Word, Excel, PowerPoint, text, HTML), photos, screenshots and clipboard text you choose to print. The app only accesses files you pick with the Android file picker or photo picker, or share to the app.
• Scans. Scanning uses the Google document scanner provided by Google Play services. Edge detection, filters and text recognition (OCR) run on your device.
• Your signature. It is stored in an encrypted file in the app's private storage.
• Printers and print history. Saved printers, recent files and your print queue history are stored in the app's private database.
• Settings. These include your default print settings, appearance, App Lock, low-ink alerts and the expiry times of rewards you earn.
• App Lock. Fingerprint, face or device PIN checks are handled by Android. The app never receives your biometric data.

This data is removed when you uninstall the app or clear its storage.

3. Printing on your local network

To find and use printers, the app searches your Wi-Fi network using standard network discovery. It sends your print jobs directly to the printer you select using the Internet Printing Protocol (IPP). It also reads printer status and ink levels from that printer.

If you choose the system printer option, Android's print service and the print service plugins installed on your device handle the job. Their own privacy terms apply.

4. Web pages you share

When you share a web link to the app, the app loads that page from the internet so it can be turned into a PDF for printing. The website you open receives your request in the same way as when you visit it in a browser.

5. Information collected by third-party services

The app uses the following Google services. They may collect information from your device as described in their own policies.

Service	Purpose	Data it may collect
Google AdMob (Google Mobile Ads SDK)	Show banner, native, interstitial, app open and rewarded ads	Advertising ID, IP address and approximate location derived from it, device and app information, ad interactions
Google User Messaging Platform	Ask for and store your ad consent choices where required by law	Consent choices, device information
Firebase Analytics	Understand how features are used, for example when a print completes or a scan is saved	App interactions, app instance ID, device information, approximate location
Firebase Crashlytics	Find and fix crashes	Crash logs, device state at the time of the crash, app instance ID
Firebase Remote Config	Adjust app settings such as ad frequency without an update	App instance ID, device information
Google Play In-App Review	Let you rate the app without leaving it	Handled by Google Play

The analytics events we use do not contain the content or names of your files.

6. Ads, consent and rewards

• If you are in a region where consent is required, such as the EEA, the UK or Switzerland, the app asks for your consent before ads are personalised. You can change your choice at any time in Settings > Privacy options.
• You can reset or delete your advertising ID, or opt out of personalised ads, in your device's Android settings under Google > Ads or Privacy > Ads.
• Rewards are optional. When you choose to watch a rewarded ad, the app saves the reward's expiry time on your device. Rewards include Pro tools for 24 hours and no ads for 60 minutes.
• The app has no subscriptions and no in-app purchases, and it never processes payment information.

7. Permissions

• Internet and network state: to show ads, load shared web pages and reach your printer.
• Wi-Fi state, Wi-Fi multicast and local network access: to discover printers on your network.
• Notifications: requested only if you turn on low-ink alerts.
• Biometric: only for App Lock.
• Advertising ID: used by AdMob and Firebase as described above.

The app does not request camera, storage, media, contacts or location permissions.

8. Contacting support

If you tap Contact support, your email app opens with a message addressed to us. The message includes your device model, Android version and app version. Nothing is sent until you send the email yourself. We use what you send only to answer you, and we delete it when it is no longer needed.

9. Data sharing and sale

We do not sell your personal information. Apart from the Google services listed above, we do not share information with anyone, unless the law requires us to.

10. Data retention and security

Data on your device is kept until you delete it, clear the app's storage or uninstall the app. Google keeps data collected by AdMob and Firebase according to its own retention policies. For example, Crashlytics keeps crash reports for 90 days.

All data sent by the app and its SDKs over the internet is encrypted in transit. Printing to a printer on your local network may use plain IPP if your printer does not support secure IPPS.

11. Your rights

Depending on where you live, you may have the right to access, correct, delete or object to the processing of your personal data, and to withdraw consent. This includes residents of the EEA and UK under the GDPR, and California residents under the CCPA/CPRA.

Because we do not hold an account or profile for you, most data can be controlled directly on your device:

• Use Settings > Privacy options to change ad consent.
• Reset or delete your advertising ID in Android settings.
• Clear the app's storage or uninstall the app to delete local data.

For any other request, email zahidraza993@gmail.com. You also have the right to complain to your local data protection authority.

12. Children

The app is not directed at children under 13, or under the minimum age required in your country, and we do not knowingly collect their personal information. If you believe a child has provided personal information through the app, contact us and we will help remove it.

13. Changes to this policy

We may update this policy from time to time. We will post the new version at this address and change the effective date above. Significant changes will also be noted in the app's release notes.
