Your Privacy Matters

We built TalkToDai to help you learn languages through natural conversation. Here's exactly what we do with your data—in plain English.

Effective: November 22, 2025 • Last updated: November 22, 2025

The Simple Version

  • ✓Your conversations are stored to help you learn and improve the experience
  • ✓We use trusted providers (Google, Anthropic, ElevenLabs) to power AI features
  • ✓You can delete your account and all data anytime

What We Collect

To make TalkToDai work, we need to store some information. Here's exactly what:

When you sign in

Your email and basic profile from Google or Apple Sign-In. We use Supabase Auth—a trusted, secure authentication provider.

Your conversations

Messages you send and Dai's responses. This helps Dai remember your progress and personalize future conversations. You can delete everything from your account settings anytime.

Your preferences

Language choices, voice preferences, formality settings—basically the settings that make Dai work the way you want.

Technical stuff (automatic)

Basic technical info like your timezone (to show correct times), error logs (to fix bugs), and rate limits (to prevent abuse). No tracking and no ads.

How We Use Your Data

Everything we collect has a purpose. Here's what we do with your information:

  • →Make Dai smarter: Your conversations help Dai learn your style, remember context, and personalize responses
  • →Generate audio: We create voice messages for your learning experience (stored securely with private URLs)
  • →Keep things secure: Monitor for abuse, fix bugs, prevent spam—standard security stuff
  • →Legal compliance: We follow the law and protect both you and us

Important: Dai is AI, Not a Human

Dai is a generative AI that creates responses in real-time. Sometimes it might say things that sound insightful about you, but these are AI-generated patterns—not facts. Dai can be wrong.

Don't share sensitive info you wouldn't share with any other AI chatbot. Dai is not a therapist, doctor, or professional advisor. If you're in crisis, please contact emergency services or a qualified professional.

Use common sense. Dai is here to help you learn languages and have interesting conversations—treat it like you would any AI tool.

Dai may use third-party services for AI processing. These include OpenAI, Anthropic, Google Gemini, ElevenLabs, Deepgram, and OpenAI Whisper. These are the same services that power other popular AI chatbots like ChatGPT and Claude. Your data has the potential to be sent to these services and processed by them, abiding by their privacy policies and terms of service. These partners help us run the service—that's it. If required by law, we may disclose information to authorities.

Who We Share With (And Why)

We work with trusted companies to make TalkToDai work. Here's the complete list:

Supabase (industry-standard secure infrastructure)

AI Conversation

Anthropic Claude, Google Gemini, OpenAI—your messages are sent to these services to generate responses
