Privacy Notice
Last Updated: 02/07/2026

This Privacy Notice explains how Luscinia collects, uses, and protects information when you use our Service.

1. Privacy-First Design Philosophy
   Luscinia is built on a local-only, privacy-by-design architecture. The Service is intentionally engineered to minimize data collection and prevent the transmission of sensitive user information to external systems.
2. Information We Do Not Intentionally Collect
   Luscinia does not intentionally collect or store:

Raw authentication tokens or passwords
Session cookies or authorization headers
Personally identifiable information contained in application payloads
Full network traffic beyond short-lived, user-controlled local buffers
3. Information That May Be Processed Locally
The Service may temporarily process the following information locally on your device:

Network request metadata and payloads
Console logs and error messages
User interaction context (clicks, inputs)
Masked placeholders replacing sensitive values
This information remains under your control and is subject to auto-deletion settings.

1. AI Processing
   When AI analysis is triggered, technical data is sanitized using masking mechanisms before any model interaction occurs. Masked data may be processed by AI components, while original sensitive values remain exclusively in volatile local memory.
2. Usage Analytics
   Luscinia may collect limited, non-identifying usage analytics such as feature usage frequency or error rates to improve product quality. These metrics are aggregated and do not include sensitive application data.
3. Data Retention
   Local data retention is configurable by the user. By default, captured data is automatically deleted after a short interval. Luscinia does not retain user debugging data on its servers unless explicitly stated.
4. Data Sharing
   Luscinia does not sell, rent, or trade personal data. Data is not shared with third parties except where required by law or with trusted service providers strictly necessary to operate the Service.
5. Your Rights
   Depending on your jurisdiction, you may have rights regarding your personal data, including access, deletion, and restriction. Because Luscinia minimizes centralized data storage, most data control occurs directly on your device.
6. Security Measures
   Luscinia employs technical and organizational safeguards designed to protect data integrity and confidentiality. However, no system can guarantee absolute security.
7. Changes to This Notice
   This Privacy Notice may be updated periodically. Material changes will be communicated through the Service or website.
