1. Introduction

AI Triple Chat (hereinafter referred to as "the App") is designed with your privacy given the highest priority. This Privacy Policy outlines how we handle user information in the App.

2. Data Storage Location

The App operates on a "Local First" principle.

• Chat Logs: All conversation history is stored on your computer's local storage. It is never transmitted to our (the developer's) servers.
• API Keys: If you use the BYOK plan, the API keys you input are encrypted and stored securely using your OS's standard security features (Windows Credential Manager, macOS Keychain, etc.).

3. Data Transmission to External AI Services

The App utilizes the following third-party AI services to provide functionality. Conversation data is transmitted to these services based on user instructions.

• Google Gemini API (Google): Google Privacy Policy
• OpenAI API (OpenAI): OpenAI Privacy Policy

※ If you use the BYOK (Bring Your Own Key) plan, your data is processed according to the terms of the API providers. Generally, data sent via API is not used for training, but please check the latest terms of each company.

4. About SaaS Plan (Standard Plan)

If you use the SaaS Plan (Standard Plan), requests are routed through a proxy server on the cloud (Google Cloud Run) to relay API requests and measure token usage. Even in this case, the content of your conversations is not permanently stored.
