Thank you for choosing to use the Lumos application (“Lumos,” “we,” “us,” or “our”). We highly value your personal information and privacy. This Privacy Policy explains how we collect, use, store, and protect your information, as well as the rights and choices available to you.
By using Lumos, you agree to the collection and use of information in accordance with this Privacy Policy.
This Privacy Policy is effective as of January 1, 2026.
During your use of the Lumos application, we may collect the following information, which is associated with your user-defined ID:
Account and Authentication Information
This includes Apple authentication tokens obtained through Sign in with Apple (used solely to verify your Apple account identity), as well as the user-defined ID you set within Lumos, which is used to associate your usage data and records with your account.
Usage Data
Statistical data related to your use of AI features within the application, such as your total daily token consumption (tokens are units used to measure AI request processing), and token usage across different functional areas.
User Preferences
Information about whether you have modified your user-defined ID and whether you have enabled the built-in AI services within the application (such as the Qwen model).
Planned Data Collection
In the future, we plan to collect interaction frequency and activity data across different functional modules to analyze usage patterns and improve product features. We will obtain your explicit consent before collecting such data.
Important Notice
All of the above information is associated with your user-defined ID, which is created by you. We are unable to identify or trace your real-world identity through this ID.
We strictly use the collected information only for the purposes described in this Privacy Policy, including:
Providing Core Functionality
Using Apple authentication tokens to verify your identity and ensure secure access to your Lumos account. Your user-defined ID is used to bind your data and preferences to your account, enabling a consistent experience across devices and sessions.
Service Maintenance and Improvement
Token usage data is used to monitor application usage and performance. For example, we record daily and feature-level token consumption. This allows you to understand your own usage while also helping us conduct internal analysis to improve system performance and feature design.

We tailor your experience based on your account settings. For example, if you enable the built-in AI services, we will provide the corresponding AI features. If you change your user-defined ID, we will update our records accordingly to ensure accuracy.
