Privacy Policy

1. Overview

At Aichiki, we believe in privacy-first design. Our goal is to provide engaging, AI-powered character interactions and creative tools while minimizing the personal data we collect. This Privacy Policy explains what data we collect, how we use it, and how you can control it.

2. What Data We Collect

We collect the minimum data required to provide, personalize, and improve the Aichiki experience.

Information you provide

• Display Name (required, but can be any text you choose)
• Email Address (required for account creation)

User-generated content

• AI chat messages
• Custom characters and prompts

App usage data

• App interactions (e.g. message counts, screen opens)
• Crash logs and diagnostics
• Session and device-level behavior (for analytics and debugging only)

3. How We Use Your Data

We use your data only for the following purposes:

• To operate and improve the app
• To save your chats and characters across devices
• To provide support and debug errors
• To understand which features users engage with (e.g. to improve UI or chat models)
• To log and analyze feedback about the app when shared with our support AI character @aichiki, which helps us improve the platform. Only app-related feedback is automatically extracted by AI systems - we don't read your original messages, and only collect the extracted feedback summaries to guide future development

We do not:

• Sell your data
• Use it for advertising
• Share it with marketing services

AI Provider Commitments

All AI providers we work with maintain high standards for data protection:

• They do not use customer API data to train their models without explicit consent
• They comply with industry-standard security practices and data protection regulations
• Major providers (OpenAI, Anthropic, Google, xAI, Mistral) have explicit policies against training on API customer data

Summary: We do not use these services to track or profile you, and we avoid including personal identifiers whenever possible. Our AI service integration does not link your identity to the data sent for processing.

5. Content Moderation

To keep Aichiki safe and appropriate for all users aged 13 and up:

• We use OpenAI's Omni Moderation and custom filters for both text and images
• Offensive or unsafe content is blocked or filtered automatically
• Potentially inappropriate content is analyzed through a multi-step AI review process and rejected if it violates our standards (see our Terms and Content Guidelines for details)
• All AI content is generated based on prompts and filtered using industry-standard safety tools

6. Data Retention

• Chat logs and character data are retained as long as your account is active
• Diagnostic and usage data is retained only as long as needed to improve the app or resolve technical issues

7. Cookies and Authentication

AICHIKI uses cookies only for essential authentication purposes:

• We use cookies solely for Firebase authentication to enable you to log in and maintain your session
• Firebase Authentication may set cookies from Google domains (such as accounts.google.com) to facilitate the login process
• These cookies are strictly necessary for the platform to function properly
• We do not use any analytics cookies, tracking cookies, or advertising cookies
• Without these essential authentication cookies, you would not be able to log in to your account

As we only use essential cookies for authentication and no optional cookies, there are no cookie preferences to manage.

• Data Export: You can export all your data at any time through your account settings
• Account Deletion: You can permanently delete your account and all associated data through your account settings
