Privacy Policy

Effective Date: May 18, 2026

MzaLogics ("we", "us", or "our") operates the Docu Viewer mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App. Please read this Privacy Policy carefully. By using the App, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

1.1 Information You Provide to Us

The App is designed to work with documents stored on your device. We do not require you to create an account or provide personal information to use the basic features of the App.

1.2 Automatically Collected Information

When you use the App, we may automatically collect certain information, including:

• Device Information: Device model, operating system version, unique device identifiers, and mobile network information.
• Usage Data: Information about how you interact with the App, such as features used, time spent, and app performance data.
• Document Metadata: When you open a document through the App, we may read basic metadata (such as file name, file type, and file size) to display and organize your documents. We do not access or transmit the actual content of your documents to our servers.
• Crash Reports: If the App crashes, we may collect diagnostic information to help us identify and fix issues.

1.3 In-App Purchase Information

If you purchase a premium subscription, transaction information is processed by Google Play's billing system. We do not store your payment details. We only receive confirmation of your subscription status from Google Play.

2. How We Use Your Information

We use the information we collect for the following purposes:

• To provide, maintain, and improve the App's functionality
• To personalize your experience (e.g., remember recent documents and favorites)
• To process and manage your premium subscription
• To analyze usage patterns and improve App performance
• To detect, prevent, and address technical issues and crashes
• To send promotional notifications (only if you have granted permission)
• To display relevant advertisements (for non-premium users)

3. Third-Party Services

We use the following third-party services that may collect information:

3.1 Google Firebase

We use Firebase Analytics to understand how users interact with the App and Firebase Crashlytics to monitor and fix crashes. These services collect anonymous usage and diagnostic data. For more information, please visit Firebase Privacy Policy.

3.2 Google AdMob

We use Google AdMob to display advertisements in the free version of the App. AdMob may collect and use device information to serve personalized or non-personalized ads. You can opt out of personalized ads through your device settings. For more information, please visit Google Privacy Policy and AdMob Help.

3.3 Google Play Services

We use Google Play Billing Library to handle in-app purchases and subscriptions. Google processes all payment transactions. For more information, please visit Google Privacy Policy.

3.4 Google Play In-App Review API

We may use the Google Play In-App Review API to prompt you to rate the App. This process is handled entirely by Google Play and does not share any personal information with us.

4. Data Storage and Security

• Local Storage: Your recent documents list and favorites are stored locally on your device using Android's secure SharedPreferences. This data never leaves your device.
• Document Content: The actual content of your documents is never uploaded to our servers. All document viewing and processing happen locally on your device.
• Security: We implement reasonable security measures to protect your information. However, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.

5. Your Choices and Rights

• Premium Subscription: You can purchase a premium subscription to remove advertisements.
• Notifications: You can disable promotional notifications at any time through your device settings or the App's settings.
• Ad Personalization: You can opt out of personalized advertising by adjusting your device settings or visiting Google Ads Settings.
• Clear Data: You can clear your recent documents history and favorites from within the App settings. You can also clear all App data through your device's application settings.
• Data Deletion: Since we do not collect or store personal data on our servers, there is no account deletion process. To remove all locally stored data, simply uninstall the App or clear the App data from your device settings.

6. Children's Privacy

The App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can take appropriate action.

You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
