Introduction

Welcome to PhantaMate (the "App"). We take your privacy and the security of your personal information seriously. This privacy policy explains how we collect, use, store, and protect your personal information.

By using the App, you agree to the terms of this privacy policy. If you do not agree with these terms, please stop using the App.

1. Information We Collect

1.1 Local-First Principle

PhantaMate is built on a local-first design philosophy. Your data is stored primarily on your own device, and we keep the collection and processing of personal information to a minimum.

1.2 Information We Collect

• Device information: app version, operating system version, and device model (used for compatibility optimization and error diagnosis)
• Usage data: app launch counts and feature usage frequency (used to improve the product experience)
• Error logs: app crash and error information (used to fix problems)

1.3 Information We Do Not Collect

• Documents you upload, create, or edit locally
• Your chat history and conversation content
• Your personally identifiable information (name, phone number, address, etc.)

2. How We Use Information

The limited information we collect is used only for the following purposes:

• Providing and improving the features and services of the App
• Diagnosing and fixing technical problems
• Analyzing usage trends to optimize the user experience
• Ensuring the security and stability of the App

3. Data Storage and Security

3.1 Local Storage

Your personal data and content are stored primarily on your local device. We use encryption to protect locally stored data and keep it secure.

3.2 Data Transmission

When communication with our servers is required (such as feature synchronization or error reporting), data is protected in transit using the HTTPS encryption protocol.

3.3 Data Retention

Except where the law requires otherwise, we do not retain your personal data longer than necessary. You may delete your local data at any time; once deleted, the data cannot be recovered.

4. Third-Party Services

What leaves your device, to whom, and why

• AI conversation content: when you send a message, the text of that conversation and the selected character context are sent to the AI model provider you configured, solely to generate a reply. This transfer happens only after you tap "Agree and continue" at the AI disclosure prompt, and only when you actively send a message.
• Model service credentials: any API key you enter is stored in the device Keychain and sent only to the model provider you specified. We do not receive or store it.
• Crash analytics: crash logs and basic device information are collected to help us improve stability.

We do not use your conversation content for advertising, profiling, or model training. Each third-party provider processes data under its own privacy policy; please review the policy of the model service you choose.

5. Your Rights

You have the following rights with respect to your data:

• Access: you can view the data stored locally
• Deletion: you can delete all locally stored data at any time
• Export: you can export your local data
• Choice: you can decline to grant non-essential permissions

6. Children's Privacy

The App is intended solely for users aged 18 and over. We do not knowingly collect personal information from anyone under 18. During onboarding you are asked to declare your age; if you declare an age under 18, access is blocked with a terminal notice and no further data is collected or processed.

7. Updates to This Privacy Policy

We may update this privacy policy from time to time. The updated policy will be published within the App, and the update date will be noted on this page. For material changes, we will notify you through in-app notifications or similar means.
