Privacy Policy
Last updated: December 2025
Our Commitment to Your Privacy
At nidraro, we believe your personal data belongs to you and only you. That's why we've built nidraro to work entirely on your device, without collecting, storing, or transmitting any of your information.
Simply put: we collect nothing.
Data We Don't Collect
nidraro does not collect, process, or store any of the following:
- Personal information (name, email, phone number)
- Account credentials (there are no accounts)
- Location data
- Device identifiers
- Usage analytics or telemetry
- Advertising identifiers
- Crash reports sent to external servers
- Any health or fitness data
Data That Stays on Your Device
nidraro processes the following data locally on your iPhone and Apple Watch. This data never leaves your devices:
- Heart rate data — Accessed from Apple Watch via HealthKit, used solely for sleep detection
- Motion data — Accelerometer readings from Apple Watch to detect movement patterns
- Session history — Records of your sleep monitoring sessions, stored locally for 30 days
- App preferences — Your settings and configurations
All processing happens on-device. Your health data is never transmitted to any server, cloud service, or third party.
HealthKit Integration
nidraro uses Apple HealthKit to access heart rate data from your Apple Watch. This integration is used exclusively for detecting when you fall asleep.
- We only read heart rate data during active monitoring sessions
- We do not write any data to HealthKit
- We do not access any other HealthKit data types
- Heart rate data is processed in real-time and not permanently stored
You can revoke HealthKit access at any time through your iPhone's Settings app under Privacy & Security > Health > nidraro.
No Third-Party Services
nidraro does not integrate with any third-party services, including:
- Analytics platforms (no Google Analytics, Mixpanel, etc.)
- Advertising networks
- Social media SDKs
- Crash reporting services
- Cloud storage providers
The app contains no third-party code that could collect or transmit your data.
No Network Communication
nidraro does not require an internet connection to function. The app makes no network requests and does not communicate with any external servers.
The only network activity related to nidraro is downloading the app from the App Store and receiving app updates.
Data Retention
Session history is stored locally on your iPhone for 30 days, then automatically deleted. You can manually delete all session history at any time from within the app.
When you delete the nidraro app, all locally stored data is permanently removed from your device.
Your Rights
Since we don't collect any personal data, there is nothing for us to:
- Share with third parties
- Sell to advertisers
- Provide upon request (we have nothing to provide)
- Delete from our servers (we have no servers storing your data)
You have complete control over your data because it never leaves your device.
Children's Privacy
nidraro does not collect personal information from anyone, including children. The app is rated 4+ and is safe for users of all ages.
Changes to This Policy
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. Our commitment to not collecting your data will not change.
