Privacy Policy

Effective Date: October 19, 2026
App Name: DeepReader
Package Name: com.3alemneup.deepreader
Developer: 3alemneup

DeepReader respects your privacy. This Privacy Policy explains how the application handles information, what data may be processed by third-party services, and how you can manage your data.

1. Privacy-First Design: Offline Reading and Processing

DeepReader is designed to provide its core reading and learning features directly on your device.

• No user accounts required: You can use DeepReader without registering, logging in, or creating an account.

• Local storage: Imported books (PDF and EPUB files), reading progress, notes, highlights, vocabulary collections, flashcards, and reading statistics are stored locally on your device in an Isar database, where applicable.

• On-device processing: Reading, vocabulary management, dictionary lookups, OCR (optical character recognition), translation, text-to-speech (TTS), and flashcard features are designed to operate locally, using on-device resources and models where applicable.

• No developer-operated content servers: DeepReader does not upload your books, reading notes, highlights, or vocabulary to developer-operated servers as part of its standard offline functionality.

Certain optional features, including advertising, in-app purchases, and Google Drive backup and synchronization, may require an internet connection and involve third-party services.

2. Third-Party Services and Data Processing

DeepReader integrates the following third-party services. These services may process information according to their own privacy policies and applicable settings.

A. Google AdMob — Advertising

The free version of DeepReader may display advertisements through Google AdMob.

Depending on the device configuration, consent choices, and applicable advertising settings, Google and its advertising partners may collect or process information such as:

• Advertising identifiers and related advertising signals.

• Device information, including device type, operating system, and technical identifiers.

• IP address and approximate location derived from it.

• Advertising interactions, diagnostics, and usage information necessary to deliver, measure, and improve advertisements.

The information processed and whether advertisements are personalized depend on applicable consent requirements, user settings, and Google's policies.

DeepReader does not sell users' personal information.

For more information, please consult:

• Google Privacy Policy

• Google AdMob and publisher policies

B. Google Play Billing — In-App Purchases

DeepReader may offer paid features, including a Pro upgrade through a subscription or lifetime purchase, depending on the available purchase options.

Purchases are processed through Google Play Billing.

• Google Play handles payment processing.

• DeepReader does not directly collect or store your complete credit card number or banking credentials.

• The application receives purchase-related information, such as purchase status and transaction identifiers, as needed to validate purchases and unlock the corresponding features.

Google Play processes payment information under its own privacy policy and terms.

For more information, consult the Google Play Terms of Service.

C. Optional Google Drive Backup and Synchronization

DeepReader may offer an optional backup and synchronization feature using Google Drive.

This feature is not required to use the application's core offline reading functions.

If you choose to connect Google Drive and enable backup or synchronization:

• Selected application data, such as reading progress, notes, and vocabulary collections, may be uploaded to your Google Drive app-data storage area (appDataFolder), depending on the feature's implementation.

• The data is stored in association with your Google account and is subject to Google's applicable policies and storage controls.

• DeepReader does not require you to enable this feature to read books or use its offline learning tools.

• DeepReader does not store your Google account password on developer-operated servers.

When backup and synchronization are disabled, the application does not use this feature to upload your local reading data.

You can revoke DeepReader's Google Drive access through your Google Account permissions. Revoking access may prevent future backups or synchronization but may not automatically delete data already stored in Drive.

3. Internet Access and App Permissions

DeepReader may request or use the following permissions, depending on the features enabled and the Android version:

• File access: To select, import, and open PDF and EPUB documents.

• Internet access: To load advertisements, communicate with Google Play Billing services, and perform optional Google Drive backup or synchronization.

• Audio playback or foreground service permissions: Where required by Android, to support text-to-speech playback while the application is running in the background or the screen is off.

Permissions are used to support the corresponding application features. Actual permissions may vary by Android version and implementation.

4. Children's Privacy

DeepReader is not intended to knowingly collect personal information directly from children under the age of 13.

The application does not require users to create accounts. However, third-party services integrated into the application may process information under their own policies and applicable age-related requirements.

If you believe that personal information has been collected inappropriately through DeepReader, please contact the developer using the details in Section 7.

5. Your Choices and Data Control

Local Data

Your books, notes, highlights, flashcards, vocabulary collections, and reading statistics are stored locally on your device.

You can manage this data by using the application's available controls, clearing its storage through Android settings, or uninstalling the application. Clearing app storage or uninstalling the application may permanently delete locally stored data that has not been backed up.

Before clearing storage or uninstalling DeepReader, back up any data you want to keep.

Advertising Preferences

You can manage advertising privacy settings and advertising identifiers through your Android device settings, where available. You may also be able to manage consent and personalized advertising preferences through the options provided by Google or the application.

Upgrading to DeepReader Pro may remove advertisements if ad removal is included in the purchased version.

Google Drive Backup

Google Drive backup and synchronization are optional. You can choose whether to connect your account and enable the feature.

You can also manage or revoke the application's access through your Google Account settings.

6. Data Security and Retention

DeepReader stores core reading and learning data locally on your device. The security of locally stored information also depends on your device's security settings and access controls.

Data backed up to Google Drive is subject to Google's storage and security practices. Information processed by advertising and billing providers is subject to their respective policies.

Local data remains on your device until you delete it, clear the application's storage, uninstall the application, or otherwise remove it. Data stored in third-party services may have separate retention and deletion procedures.

7. Changes to This Privacy Policy

This Privacy Policy may be updated periodically to reflect changes to DeepReader's features, third-party integrations, or applicable legal requirements.

The latest version will be published at the public URL where this policy is hosted. The effective date will be updated when material changes are made.
