Effective date: June 15, 2026 · Last updated: June 11, 2026

Thank you for choosing PeakState (“PeakState,” “the App,” “we,” “us,” or “our”). We understand how important your personal information is to you, and your trust matters deeply to us. We comply with applicable laws and regulations and implement appropriate security measures to keep your personal information safe and under your control.

Important Notice: The energy management suggestions provided by PeakState are for informational purposes only and do not constitute medical advice. If you have any health concerns, please consult a qualified healthcare professional. PeakState accepts no liability for any health issues arising from your use of the App.

1. Information We Collect and How We Use It

1.1 Account Registration Information

When you create a PeakState account, we collect:

  • Email address: used for account sign-in, password recovery, and important notifications
  • Nickname (optional): used to address you in a personalized way
  • Avatar (optional): used for account identification

1.2 Health Data (via HealthKit)

To provide personalized energy management insights, the App reads your HealthKit data. All health data is stored only on your device and is never uploaded to our servers.

We read the following categories of health data:

  • Sleep data: total sleep duration, deep sleep duration, REM sleep duration, bedtime, and wake-up time, used to assess sleep quality and recovery status
  • Heart rate data: resting heart rate and exercise heart rate, used to assess physical load and stress levels
  • Heart rate variability (HRV): used to assess autonomic nervous system function and recovery status
  • Step count: used to assess daily activity levels
  • Workout records: workout type, duration, and calories burned, used to assess physical exertion
  • Respiratory rate: used to assess stress and relaxation states
  • Mindfulness minutes: used to assess mental wellness activities

Data Storage Note: Health data is stored only on your iPhone and is accessed through the HealthKit framework. The App does not upload this data to any cloud server. You can revoke the App’s access at any time in Settings > Health > Data Access & Devices.

1.3 Calendar Data

To analyze your workload density and identify recovery windows, the App reads your calendar data:

  • Meeting times and durations: used to assess workload and identify open time blocks
  • Number of meetings: used to analyze schedule density

Privacy Protection: We do not read sensitive content such as meeting titles, attendees, or locations — only time-slot information. Calendar data is stored only on your device and is never uploaded to our servers.

1.4 Screen Time Data

To help you manage your digital wellbeing, the App accesses your Screen Time data:

  • Per-app usage time: usage duration statistics for individual apps
  • Device pickups: used to assess attention fragmentation
  • Total screen time: your daily total screen usage

Data Storage Note: Screen Time data is stored only on your device. We upload only aggregated statistics (such as total duration and pickup counts) to our servers; we never upload lists of specific app names.

1.5 Location Information

To provide weather data and analyze how weather affects your energy, the App requests access to your location:

  • City-level location: used to retrieve current weather, temperature, air quality, and other environmental data

Privacy Protection: We use only city-level location (for example, “Beijing”); we do not track or store your precise location (such as a street address). You may grant the “While Using the App” location permission, and we never track your location continuously in the background.

1.6 Voice Data

When you use the voice input feature:

  • Voice recordings: used solely for speech-to-text conversion; raw audio is never stored or uploaded
  • Transcribed text: used for the AI conversation feature

Speech recognition is performed locally on your device using Apple’s Speech Recognition framework.

1.7 Camera and Photo Library

When you use the nutrition tracking feature:

  • Meal photos: used by AI to identify foods and estimate nutritional content

Privacy Protection: Photos are uploaded to the Claude AI service for food recognition but are never stored permanently. Once recognition is complete, the image is immediately deleted from the server.

1.8 AI Conversation Data

When you chat with the AI assistant, we collect and process:

  • Conversation content: used to generate personalized recommendations and maintain conversational context
  • Conversation history: stored on our cloud servers (MongoDB) to support multi-device sync and long-term memory

We apply the following limitations to waitlist data:

  • No IP addresses are stored in connection with your waitlist signup
