Privacy Policy
Effective: March 21, 2026
My AI Friend ("we", "our", "the App") is operated by Ttech. This Privacy Policy explains how we collect, use, and protect your information.
1. Information We Collect
- Device Information: We generate a random device identifier to provide our services. We do not collect your name, email, phone number, or Apple ID unless you choose to provide it.
- Chat Messages: Messages you send are processed by our AI service to generate responses. Premium users' messages are encrypted (AES-256-GCM) and stored on our servers for cloud sync. Free users' messages are stored only on your device.
- Usage Data: We collect anonymous usage data including daily message counts, feature usage, and crash reports to improve our services.
- Purchase Information: If you subscribe to Premium, Apple processes your payment. We receive a transaction receipt to verify your subscription status but do not have access to your payment details.
2. How We Use Your Information
- To provide and improve our AI conversation service
- To manage your subscription and premium features
- To prevent abuse and ensure fair usage
- To provide cloud sync for premium users
- To display relevant advertisements to free users
3. Advertising & Ad Personalization
Free users may see advertisements provided by third-party ad networks (such as Google AdMob). These networks may collect and process:
- Device identifiers (IDFA/GAID) for ad personalization
- IP address and approximate location for geo-targeted ads
- Ad interaction data (impressions, clicks, views)
- Device information (model, OS version, screen size)
You can opt out of personalized advertising through your device settings (iOS: Settings > Privacy > Tracking). When you opt out, you will still see ads, but they will not be personalized. Premium subscribers see no advertisements.
4. Data Security
We use industry-standard security measures including:
- AES-256-GCM encryption for stored messages
- HTTPS for all data transmission
- Per-device encryption keys derived using HKDF
- Server-side rate limiting and abuse protection
