What We Collect

Koffee stores your caffeine logs, drink preferences, and profile settings (weight, metabolizer type, bedtime) locally on your device. We do not collect or transmit personal health data to our servers.

How We Use It

Your data is used exclusively within the app to calculate caffeine levels, generate sleep predictions, and provide personalized insights. All calculations happen on-device.

Third Parties

We do not sell, share, or provide your personal data to third parties. If you choose to sync with Apple HealthKit, that data remains on your device and is governed by Apple's privacy policies.

Analytics

We may collect anonymous, aggregated usage analytics (e.g., feature popularity, crash reports) to improve the app. This data cannot be used to identify you.

Your Rights

You can delete all your data at any time from within the app settings. Since your data lives on your device, deleting the app removes all associated data.
