Privacy Policy
Your sleep data is deeply personal. We believe it should stay that way.
Our Core Privacy Principle
Lulra was built with privacy as its foundation. We believe that your health data, sleep patterns, and Heart Rate Variability (HRV) belong to you and no one else. We do not collect, process on servers, sell, or share your health data.
On-Device Processing
Lulra operates almost entirely on your Apple Watch. All health monitoring, HRV analysis, and sleep phase estimations are calculated locally on your device's processor using Apple's HealthKit framework. This ensures that your private biometric data never leaves your hardware.
Apple HealthKit Integration
When you use Lulra, we request permission to read data from Apple Health to perform our sleep smoothing features. Specifically:
- Heart Rate Variability (HRV): Read to estimate changes in your sleep architecture.
- Heart Rate and Motion: Read to help confirm sleep states.
We only request the data strictly necessary for the app to function. This data is read instantly in real-time, evaluated for haptic nudges, and is not stored or transmitted by us.
No Accounts. No Tracking.
You do not need to create an account to use Lulra. All biometric data, sleep sessions, and journal entries are stored locally in your device's secure storage. Nothing is sent to external servers, no analytics are collected, and your health data never leaves your hands.
Changes to This Policy
If we ever make changes to this policy, it will be due to updates in Apple's ecosystem or the introduction of new optional features, but our commitment to "device-only" health data will never change. We will notify you of any adjustments here on this page.
