Privacy Policy
In short
- The app has no accounts and no servers of its own. Your documents, photos, scans and contacts stay on your phone.
- Files go only to the printer you choose: over a USB cable or over your local Wi-Fi network.
- The developer does not collect, sell or share your personal data.
1. What the app processes on your device
Smart Printer works with files only to show, edit, print, scan or save them. All processing, including text recognition (OCR), happens on the phone.
- Documents and photos you open or share into the app: PDF, images, Word, Excel, text files.
- Camera images, only when you start a document scan.
- Scans received from a printer's built-in scanner over USB or Wi-Fi.
- Contacts, only when you open the "Contacts" print tool and grant access. The list is used to build a printable page and is never uploaded.
2. Permissions and why they are needed
| Permission | Purpose |
|---|---|
| USB host | Print to and scan from printers connected with an OTG cable. |
| Internet, Wi-Fi state, multicast | Find printers and scanners on your local network (IPP, AirPrint, Mopria, eSCL) and send jobs to them. |
| Camera | Scan documents with the phone camera (through Google's document scanner). |
| Contacts (optional) | Print your contact list. Asked only when you use that tool. |
3. Internet connections the app makes
- Language models for OCR are downloaded once, when you ask for text recognition in a new language. Only the model file is requested; your documents are not sent.
- Update check: the app reads a small settings file to learn about new versions. No personal data is sent.
- Web page printing loads the address you type, like a browser.
- Google Play services provide the camera document scanner and in-app updates under Google's Privacy Policy.
4. Advertising
If advertising is turned on in a future version, ads are served by Google AdMob. AdMob may use your device's advertising ID and approximate location to show and measure ads, as described in How Google uses information from sites or apps that use its services. You can reset or delete the advertising ID in your Android settings.
5. Storage and deletion
PDFs and texts you save are kept in the app's own folder on your phone. You can delete them in the "Files" tab, or remove everything by clearing the app's data or uninstalling it. Printer settings such as calibration are stored only on the phone.
6. Children
The app is a general-purpose printing tool and is not directed at children under 13. It does not knowingly collect personal information from children.
7. Changes to this policy
If the way the app handles data changes, this page will be updated and the effective date above will change.
