We keep your habits private and your data in your control.

1. Overview

DayZero is a habit tracker built with a privacy-first mindset. This policy explains what information we collect, how we use it, and the choices you have.

2. Information We Collect

• Usage data such as feature interactions, app stability signals, and general diagnostics.
• Device data like OS version and device model to improve performance.
• Habit metadata you enter (titles, schedules, reminders).

3. HealthKit Integration

DayZero integrates with Apple Health / HealthKit to automatically track habits like steps, workouts, or mindfulness minutes. HealthKit access is optional and only occurs if you explicitly grant permission.

• We read HealthKit data only for the habits you choose to connect.
• We never use HealthKit data for advertising or marketing.
• HealthKit data is handled according to Apple’s HealthKit policies.

4. How We Use Information

• To calculate streaks, progress, and insights.
• To keep the app reliable, fast, and visually polished.
• To provide support when you reach out to us.

5. Sharing and Disclosure

We do not sell your data. We may share limited information with service providers strictly to operate and improve DayZero (e.g., analytics or crash reporting), and only under confidentiality obligations.

6. Data Retention

We retain personal data only as long as needed to deliver the service or comply with legal obligations. You may request deletion at any time.

7. Your Choices

• You can revoke HealthKit permissions anytime in iOS Settings.
• You can edit or delete habits and progress inside the app.
• You can request data access or deletion by contacting us.
