Privacy Policy for DocLens: PDF Reader & Scanner
Effective date: October 18, 2026
Last updated: October 18, 2026
This Privacy Policy applies to DocLens: PDF Reader & Scanner (package name "com.smart.document.pdf.doclens"), referred to in this policy as "DocLens," "the app," "we," "us," or "our." DocLens is a local-first document reader, scanner, and PDF utility for Android. This policy explains what information DocLens accesses, how that information is used, and the choices available to you.
Summary
- DocLens does not require an account.
- We do not operate servers that receive your documents, scans, images, document contents, search history, favorites, or recent-file history.
- Document viewing, searching, editing, conversion, and scanning are designed to occur on your device.
- DocLens does not sell your personal information and does not use your information for advertising.
- DocLens uses the Google Play services ML Kit document scanner. Google states that document scanning operates on-device, but the SDK may collect limited app, device, identifier, performance, and usage information for diagnostics and analytics.
- You control when a document is shared with another app or service.
Information DocLens accesses and uses
Documents and device storage
DocLens is a document-management app. To find and manage supported documents, it may request access to files in shared device storage. On Android 11 and later, this may include Android's All files access permission. On older supported Android versions, DocLens may request the applicable storage permission.
Depending on the action you choose, DocLens may access:
- file names, types, sizes, locations, and modification dates;
- the contents of documents and images you open, preview, search, scan, convert, merge, organize, sign, rename, share, or delete; and
- access references supplied by Android when you open DocLens from another app or select a file through a system picker.
DocLens uses this access only to provide the document features you request, such as discovering supported files, displaying document details, opening and searching documents, and carrying out file operations. Granting access does not cause your documents to be uploaded to us.
Scans and images
DocLens uses the Google Play services ML Kit document scanner. The scanner's camera interface, document detection, cropping, filtering, and related processing operate on-device. The scanner uses the camera permission managed by Google Play services rather than requesting the Android camera permission directly for DocLens. You choose which scanned pages are returned to DocLens.
Scanned pages and generated PDFs are stored on your device. A model or scanner component may need to be downloaded by Google Play services before first use.
App activity stored locally
To provide its features, DocLens stores limited app data on your device, including:
- favorites and recent-document references;
- search terms entered in the document library;
- reader position, bookmarks, and app preferences where supported;
- temporary working files and cached previews; and
- in-progress operation or recovery state where needed to complete a task safely.
This information is not sent to servers operated by us. Search history can be cleared from the search screen. Android's Clear storage control or uninstalling DocLens removes DocLens's app-private data. Uninstalling the app does not delete documents or outputs that you saved to shared storage.
Information processed by third-party services
DocLens includes the Google Play services ML Kit document scanner. According to Google's ML Kit disclosure documentation, ML Kit SDKs may collect information such as device manufacturer and model, operating-system version, available ML hardware, app package name and version, performance metrics, and device or per-installation identifiers for diagnostics and usage analytics. Google states that this collected information is encrypted in transit and is not transferred by ML Kit to third parties.
DocLens does not use advertising SDKs, Firebase Analytics, or a developer-operated analytics or crash-reporting service in the current version.
Google's processing is governed by its own terms and privacy policy. For more information, see:
- [ML Kit document scanner](https://developers.google.com/ml-kit/vision/doc-scanner)
- [ML Kit data disclosure information](https://developers.google.com/ml-kit/android-data-disclosure)

Sharing and disclosure
We do not sell, rent, or trade your personal information or document content.
DocLens discloses a document or generated output to another app only when you initiate an action such as Share or Open with. Android may give the receiving app temporary access to the selected file. Once you send content to another app, service, person, or storage provider, that recipient's privacy practices apply.
Information may also be processed by Google Play services as described above. We may disclose information if required by applicable law; however, because we do not operate a service that receives your documents or local app history, we generally do not possess that content.
Data retention and deletion
Your source documents and saved outputs remain on your device until you delete them. Deleting a file through DocLens is a user-requested device file operation and may not be reversible.
App-private metadata and preferences remain until you clear them using an available in-app control, clear DocLens's storage in Android Settings, or uninstall the app. Temporary files and previews may be removed after an operation, when no longer needed, or when Android clears app storage or cache.
DocLens disables Android cloud backup for its app data. Files you save outside DocLens's private storage may still be backed up or synchronized by Android, your device manufacturer, or a storage provider according to your device and account settings.
Security
DocLens is designed to process document content locally and to share files through Android content URIs with limited access grants. No method of storage or processing is completely secure, and the security of files in shared storage also depends on your device, Android version, screen lock, installed apps, and any backup or synchronization services you enable.
Children's privacy
DocLens is a general-audience productivity app and is not directed to children under 13. We do not knowingly collect children's personal information through developer-operated servers. If you believe a child has provided personal information to us directly, contact us using the details below.
International users
DocLens does not transfer your document content to developer-operated servers. Google Play services may process the limited technical information described above in countries where Google or its service providers operate, subject to Google's privacy practices.
Changes to this policy
We may update this Privacy Policy when DocLens's features, dependencies, or legal obligations change. We will update the effective date and make the revised policy available through the app, its store listing, or the website where this policy is published. Material changes will be communicated as required by applicable law.
