Privacy Policy

Last updated: February 9, 2026

RAI Inbox ("the App") is developed and operated by Aerendir Mobile Inc. ("we", "us", "our"). This Privacy Policy explains how we collect, use, and protect your information when you use the App.

1. Information We Collect

Account Information: When you sign in with Google, we receive your email address, name, and profile picture from Google's authentication service. For IMAP/Exchange accounts, we store your server credentials locally on your device.

Email Data: The App accesses your email messages, contacts, and calendar data solely to provide email management features. Email content is processed locally on your device and through our secure relay server for AI features.

Voice Data: When you use voice commands or the "Hey RAI" wake word, audio is processed in real-time and is not stored after processing.

Usage Data: We collect anonymous usage statistics (feature usage, crash reports) to improve the App. This data cannot be linked to your identity.

2. How We Use Your Information

• To provide smart contact suggestions
• To improve the App through anonymous analytics

3. Data Storage and Security

Email credentials and account data are stored locally on your device using Android's encrypted storage (Jetpack Security). Email content is cached in a local Room database for offline access.

When using AI features, email content is sent to our servers over encrypted connections (TLS 1.3). We do not permanently store your email content on our servers.
