CHM File Viewer - Reader
Last Updated: August 9, 2026

This Privacy Policy explains how CHM File Viewer - Reader ("the App", "we", "our", or "us") handles information when you use the application.

We respect your privacy and aim to keep the handling of your documents and personal information transparent.

1. Information We Access

The App is primarily designed to open and read CHM files stored on your device or made available to the App through Android's file-selection and sharing mechanisms.

Depending on your Android version and the action you perform, the App may access files that you explicitly select or provide to the App.

CHM and Document Files

When you choose a CHM file to open, the App may access the selected file in order to read, parse, display, search, and navigate its contents.

Your document files are not intentionally uploaded to our servers merely because you open or read them in the App.

2. Local App Data

The App may store certain information locally on your device to provide features such as:

This information is used to provide and improve the application's local reading experience.

3. Internet Access

The App uses network access for certain application services. Internet access is not required simply to read the contents of an already available CHM document.

Network connectivity may be used for services such as advertisements, application updates, notifications, or other features provided by the application.

4. Advertising

The App may display advertisements using Google AdMob. Advertising services may collect and process certain information according to their own policies and applicable privacy requirements.

Depending on applicable settings, regulations, and consent requirements, advertisements may be personalized or non-personalized.

For more information about Google's privacy practices, please review Google's applicable privacy documentation.

5. Push Notifications

The App may use push notification services to provide application updates, maintenance information, feature announcements, or other relevant notifications.

Notifications are controlled by Android and can be enabled or disabled through the device's notification settings.

The App may use OneSignal to provide notification functionality. OneSignal may process information necessary to deliver notifications in accordance with its own privacy policy.

6. App Updates

The App may use Google Play services to check for or provide application updates. Update-related functionality may require network connectivity.

7. File Sharing

The App provides sharing functionality that allows you to share supported text or document content with other applications.

When you choose to share content, Android transfers the selected content to the application or service you choose. The handling of that content is then governed by the recipient application's privacy practices.

8. Third-Party Services

The App may use third-party services to provide advertising, notifications, application updates, analytics or related functionality.

These services may include:

Third-party providers may process information according to their respective privacy policies and terms of service.

9. Children's Privacy

The App is not specifically directed toward children under the applicable minimum age required by local law.

We do not knowingly collect personal information directly from children through the App.

10. Data Security

We take reasonable measures to protect information handled by the application. However, no method of electronic storage or transmission can be guaranteed to be completely secure.

You are responsible for maintaining the security of your device and the files you choose to open or share.

11. Data Retention and Deletion

Locally stored application information may remain on your device until you delete it, clear application data, uninstall the App, or use available in-app options to remove the relevant information.

Documents selected by you remain under your control through the Android file system and the storage location from which they were selected.

12. Your Choices

Depending on your Android version and device settings, you may control permissions, notifications, advertising preferences, and application data through Android settings.

You can also stop using the App or uninstall it at any time.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes to the App, applicable laws, or our services.

Any updated version will be made available through the App or the privacy-policy webpage. The "Last Updated" date at the top of this page will indicate when the policy was most recently revised.
