🛡️ Privacy-First & Zero-Upload Guarantee DocReader is engineered from the ground up as a 100% on-device, offline document viewer. Your documents (PDF, Word, Excel, PowerPoint, Text) never leave your physical device. We operate zero cloud document servers and never read, upload, track, or share your files.
This Privacy Policy describes how DAS LTD ("we", "us", or "our") handles information in connection with the mobile application DocReader (package: com.dasltd.pdfreader). This policy applies to all users of DocReader on the Android platform and complies with Google Play Developer Program Policies, the General Data Protection Regulation (GDPR), and the California Consumer Privacy Act (CCPA).
Unlike many document applications, DocReader does not store or process your personal files in the cloud:
No Document Content Access: We do not transmit, view, copy, or parse the content of your PDF, Word (.docx), Excel (.xlsx), PowerPoint (.pptx), or Text (.txt) files on remote servers. All file parsing, rendering, text search, merging, splitting, and compression happen entirely on your phone's processor.
No Mandatory Accounts: You do not need to register an account, log in, or provide your name, phone number, or email address to use the application.
No Biometric or Personal Data: We do not collect or store biometric data, government IDs, or sensitive personal records.
DocReader requests only the minimum set of permissions necessary to function as a standalone document reader and local file manager:
Permission
Category
Purpose & Scope
MANAGE_EXTERNAL_STORAGE / READ_MEDIA_DOCUMENTS
Storage
Required strictly to discover, open, index, view, merge, split, and compress document files across your device's local storage. Content is processed 100% on-device and never transmitted over the internet.
CAMERA
Hardware
Used strictly when you explicitly open the Document Scanner to capture physical paper documents. Image processing is performed locally via on-device Google ML Kit models.
INTERNET & ACCESS_NETWORK_STATE
Network
Used exclusively by the Google Mobile Ads SDK (AdMob) to request and render advertisements and check connectivity status. Document viewing functions completely offline without internet.
DocReader is a 100% free application supported by non-intrusive advertising provided by Google AdMob. To serve contextual and personalized ads, the Google Mobile Ads SDK may collect certain diagnostic and device data.
Data collected by Google AdMob may include:
Device & Other IDs: Android Advertising ID (AAID), app set ID, device model, operating system version.
General Location: IP address used to estimate coarse location (city/country level) for relevant ad serving.
Performance & Diagnostics: Ad load times, click events, crash logs, and fill rate telemetry.
All advertising data transmitted by the AdMob SDK is encrypted in transit using industry-standard TLS/HTTPS protocols. For more information on how Google handles advertising data, please review:
• Google Privacy & Terms
• How Google uses information from sites or apps that use our services
Managing Personalized Ads: You can opt out of personalized advertising at any time through your Android device settings by navigating to: Settings > Google > Ads > Delete advertising ID or Reset advertising ID.
To guarantee an uninterrupted reading experience, DocReader enforces a strict internal policy: Zero advertisements are ever placed inside active document reading screens. Whether reading a PDF book, studying lecture slides, or examining financial spreadsheets, your viewing canvas remains completely free from banners, interstitials, or video ads.
Because DocReader does not operate cloud servers for user documents, we store zero user document data on our infrastructure. All temporary files generated during PDF merging, splitting, or image-to-PDF conversion reside strictly within your device's sandboxed storage and can be deleted by you at any time by clearing app cache or uninstalling the app.
DocReader is intended for a general audience (students, professionals, and general document readers aged 13 and older). We do not knowingly collect personal identifiable information from children under the age of 13. If you believe that a child has provided us with personal information, please contact us immediately, and we will take prompt steps to address it.
Depending on your location, you have rights under applicable privacy legislation, including:
Right to Physical Custody: You have full custody and control over your files on your device.
Right to Deletion: You can purge all app preferences, bookmarks, and recents at any time through the in-app Settings menu or by clearing Android App Data.
No Sale of Personal Data: DAS LTD does not sell, rent, or trade your personal information to third parties.
We may update our Privacy Policy periodically to reflect app updates or regulatory changes. Any modifications will be posted directly on this page with an updated "Effective Date".
