Privacy Policy
Last updated: February 27, 2026
Introduction
At KeepSmilin', we take your privacy seriously. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application ("App") and website.
Please read this Privacy Policy carefully. By using the App or website, you consent to the practices described in this policy.
Information We Collect
KeepSmilin' uses your device's camera for real-time facial analysis to detect smiles. We want to be completely transparent about how this works:
- Camera Access: We use your device's front camera only when you actively start a smile session.
- Facial Analysis: All smile detection happens entirely on your device using Apple's Vision framework.
- No Image Storage: We never store, save, or transmit any photos or videos captured during smile detection.
Face Data
KeepSmilin' uses Apple's Vision framework to detect smiles. Here is exactly how we handle face data:
- What We Collect: Facial landmark coordinates (lip points and eye points) are analyzed in real-time to detect genuine smiles.
- How We Use It: Face data is used exclusively to determine if you are smiling during an active smile session.
- Storage: Face data is never stored. Facial landmarks exist only in device memory during camera frames and are immediately discarded.
- Retention: Zero retention. Face data does not persist beyond the current camera frame.
- Third-Party Sharing: Face data is never shared with any third parties. All processing happens on-device.
Data We Store Locally
KeepSmilin' stores minimal data on your device to track your progress:
- Smile Count: The total number of successful smile sessions you've completed.
- Streak Information: Your current streak and maximum streak of daily smiles.
- App Settings: Your preferences for notifications and haptic feedback.
This data is stored securely in your device's local storage using Apple's UserDefaults system and is only used to provide app functionality like tracking your progress and maintaining your streak.
How We Use Your Information
We use the information stored on your device solely to:
- Track your smile progress and streaks
- Display your smile statistics and achievements
- Send you reminder notifications (if enabled)
