# Terminal Zero Privacy Policy

**Last Updated: January 15, 2026**

Terminal Zero (hereinafter referred to as "the Application") is a professional cognitive protection tool developed by SYNTE_LAB. We take your privacy extremely seriously. This policy explains how we handle information.

### 1. Core Privacy Principle: Zero-Telemetry
We adhere to a "Local-First" architecture.
* **No Trackers**: The Application does not contain any third-party analytical tools, advertising tracking SDKs, or crash reporting software (such as Firebase Analytics or Crashlytics).
* **No Cloud Sync**: All your usage data and configuration preferences are stored exclusively on your mobile device. We cannot access and do not collect any of your data.

### 2. Permission Requirements and Purpose
To implement "Cognitive Protection" features, the Application requires the following permissions:

* **Usage Stats Access**:
    * **Purpose**: Used for "Temporal Analysis" and "App Priority Sorting".
    * **Processing**: The system calculates the foreground time of each application in real-time to determine your remaining "Focus Quota." This calculation is performed entirely locally on the device.
* **Post Notifications**:
    * **Purpose**: Used to send critical alerts when your "Focus Quota" is exhausted (Protocol 03: Expired) to initiate the lockout procedure.
* **Default Home (Launcher)**:
    * **Purpose**: The Application must be set as the default home interface to establish a "Behavioral Firewall," protecting your attention through intentional physical friction (such as long-press to boot).

### 3. Data Storage Items
The Application only stores the following necessary settings in the device's `SharedPreferences`:
* **Focus State**: The current `is_focus_mode` status.
* **Return Path**: The package name of your designated "Host Launcher," used to correctly guide you back to the native system when focus mode is disengaged.
* **User Preferences**: Including audio toggles, long-press modes, and other personalization settings.

### 4. Third-Party Integration (AI Uplink)
The Application provides the "AI Uplink" feature, serving as a gateway to synthetic intelligence models:
* **Mechanism**: When you select an AI model (e.g., ChatGPT, Gemini), the Application attempts to launch the corresponding third-party app or opens its official web URL.
* **External Policies**: Once you leave the Application, your data processing is subject to the privacy policies of those third-party providers (e.g., OpenAI, Google).

### 5. Cognitive Protection
The Application implements a "Focus Reserve" (Cognitive Limit) system. This feature enforces "Access Delays" to ensure cognitive recovery and protect your cognitive capacity for the following day.

### 6. Policy Updates
We will update this policy when there are significant changes to the protection modules or architecture. We recommend reviewing the latest information via the in-app System Manual.

### 7. Contact Us
If you have any questions regarding privacy handling, please contact us through the developer channels listed in the System Manual.
