App Name: Gemmy Languages | Developer: Tatmob Developer Team
Our Commitment to Your Privacy
At Tatmob, we believe that advanced AI assistance should be powerful, private, and entirely under your control. The core philosophy of Gemmy Languages is data sovereignty. We have engineered the application with a "privacy-by-design" approach, ensuring that your personal data, language practice logs, and voice recordings remain exclusively on your physical device.
This policy outlines how we handle data, what permissions we require, and critically, what we do not do.
Data Processing & Storage (The Core Promise)
1. On-Device Processing Only
Gemmy Languages is designed to process the vast majority of your data locally. All learning history, custom vocabularies, and speech-to-text processing are stored exclusively within a secure SQLite database on your device. We do not transmit this operational data off-device for storage or analysis.
2. Local AI Engine (LiteRT)
When you utilize the built-in translation or tutor capabilities (powered by LiteRT/TensorFlow Lite), all reasoning, processing, and generation occur entirely offline on your device's CPU/GPU. No data leaves your phone during this process.
Local Network & Embedded Server Functionality
Gemmy Languages includes advanced local features for integration and control:
- Admin Control Panel: Accessible via HTTP on port 8080.
- Model Context Protocol (MCP) Server: Accessible via HTTP on port 8081.
User Responsibility for Local Security
Because these services run locally, they expose a controlled interface on your device's loopback or Wi-Fi IP address. It is the user’s responsibility to secure their physical environment and local network. We strongly recommend setting up and utilizing the required PIN/password protection within the app settings to prevent unauthorized access.
Data Collection & Tracking Policy (Zero Tolerance)
We do not collect, monitor, or transmit any of the following data:
- - Voice recordings or speech fragments.
- - Learning history or progress logs.
- - Local settings or custom vocabularies.
- - Device identifiers (IMEI, MAC address).
- - Location data (unless explicitly required).
We do not include any third-party analytics trackers, advertising SDKs, profiling tools, or telemetry services. Our business model is based on the sale of the application itself, not on user data.
