Privacy Policy for Komx Reader

Last updated: March 2026

At Komx Reader, accessible within the Komx Reader mobile application, one of our main priorities is the privacy of our users. This Privacy Policy document contains types of information that is collected and recorded by Komx Reader and how we use it.

1. Local-First Philosophy & AI Processing

Komx Reader is designed with a local-first approach to ensure your reading data remains private. This means:

• On-Device AI: All advanced image processing features, including Manga Colorization (via ONNX Runtime and TensorFlow Lite) and Text Recognition/OCR (via Google ML Kit), are performed entirely on your device. We do not upload your images or documents to any servers for processing.
• Library Data: Your reading history, bookmarks, categories, and tags are stored locally on your device's internal database.
• Supported Content: We do not host your personal comic files. The app is designed to read your local **ZIP**, **CBZ**, and **folders containing images** (JPEG, PNG, WEBP) directly from your device.

2. Information Collection and Identifiers

To ensure fair usage of our services and to manage premium features, Komx Reader may collect and store certain identifiers:

• Device Identifier: We use a unique, non-personally identifiable device ID solely to track **AI colorization quotas**. This identifier is used to prevent the manipulation of usage limits and ensure fair access to AI processing resources.
• Purchase Tokens: When you subscribe to "Komx Reader PRO" via Google Play, we receive a non-identifiable purchase token. This token is used to verify your subscription status with Google's servers. We do not collect your name, credit card details, or address.

3. Third-Party Services

To support development and provide essential services, we integrate the following third-party providers:

• Google AdMob: We use AdMob to display advertisements. AdMob may collect and use identifiers (such as the Android Advertising ID) to show personalized or non-personalized ads.
• Firebase (Analytics & Crashlytics): We use Google Firebase to understand app performance and stability. This collects anonymous data such as device model, app version, and crash logs to help us improve the app.

4. In-App Browser

Komx Reader includes a "Web Reader" feature that allows you to browse third-party websites. Please be aware that when you visit these websites, you are subject to their respective privacy policies and terms of service. Komx Reader does not track your browsing history outside of your locally saved bookmarks.

5. Data Deletion and Persistent Data

Local Data: You have full control over your reading library. You can delete individual items or clear your entire local database within the app settings.

Persistent Data: Please note that your **AI colorization quota** is securely linked to your unique device ID to prevent manipulation of usage limits. Clearing local app data or uninstalling the application will not reset these quotas. This data is maintained for as long as it is necessary to provide the service and prevent fraud.

Subscription Data: Your "PRO" status is linked to your Google Play Account and can be restored on any compatible device where you are logged into that account.

If you wish to request the deletion of data associated with your device identifier, please contact us at the email address provided below.

6. Permissions Usage

To function correctly, Komx Reader requires the following permissions:

• Internet: Required for the Web Reader browser, displaying advertisements, and verifying subscription/quota status.
• Notifications: Required for reminders or status updates regarding background tasks.
• Storage (SAF): Used to read supported comic formats (**ZIP**, **CBZ**, and **image folders**) from your selected directories.
