Plain English. Notes and other private Nightjar content are encrypted on your iPhone. If you turn on iCloud Backup, an encrypted copy goes only to your personal iCloud. Apple Health sleep data stays in HealthKit and is never uploaded by Nightjar. Limited pseudonymous product analytics help me improve the app, but they never include your notes, health data, name, email, Apple ID, or advertising identifiers.
1. Who is responsible
Nightjar is an iOS app created and operated by Jugal Mistry (“I,” “me,” or “Nightjar”). The app is available at apps.apple.com/app/id6800338659.
Website: nightjar.fm
Email: [email protected]
2. Private data in the app
Nightjar may store information you choose to create in the app, including private notes and titles, jars, listening progress, favourites, feedback, preferences, and app settings. This information is stored on your device.
Private note text and other sensitive Nightjar fields are encrypted on the device. If you explicitly enable iCloud Backup, Nightjar stores an encrypted backup in the private database of your personal Apple iCloud account. Nightjar has no user account system and I cannot read that encrypted content.
iCloud Backup is optional. If it is off, your Nightjar data remains on your device. Downloads and some temporary app data are not included in the backup.
3. Apple Health
If you choose to connect Apple Health, Nightjar requests read-only access to last night’s asleep duration. Health data is read on your device when needed. Nightjar does not persist it, copy it into Nightjar’s iCloud backup, use it for story recommendations or advertising, or send it to analytics.
You can disconnect Nightjar or change its Health permissions at any time in the app or in iPhone Settings.
4. Product analytics
Nightjar uses a third-party analytics service to understand whether the app works and which features are useful. Analytics are pseudonymous: the provider uses a random installation identifier, not your name or Apple identity. You can opt out through Nightjar’s privacy control, which stops future capture and resets the device-local analytics identity.
Analytics may include:
- App opens, onboarding progress, feature use, and playback milestones
- Coarse totals, ratings, and structured choices made inside the app
- App version, OS major version, broad device class, and subscription state
- Country and first-level region derived by the provider from a network request
Analytics never include:
- Your name, email, phone number, Apple ID, contacts, or precise location
- Your raw notes, note length, HealthKit data, or iCloud identifiers
- Advertising identifiers, cross-app tracking identifiers, or payment details
- Session recordings, screen captures, crash logs, or free-form text
The analytics provider is configured to discard the raw source IP and finer location fields before storage. Product event data is retained for up to 90 days. Turning analytics off prevents new events; previously processed events expire under that retention period.
5. Purchases and subscriptions
Apple processes in-app purchases through the App Store. A third-party subscription service may verify entitlement status and support purchase management. Nightjar does not receive or store your full payment-card details. Apple’s terms and privacy practices apply to App Store transactions.
6. Other third-party services
Nightjar may communicate with carefully limited service providers for these purposes:
- Apple services for private iCloud backup, HealthKit access, App Store purchases, and on-device notifications
- Analytics processing for the pseudonymous product events described above
- Subscription infrastructure for entitlement and purchase status
- Content delivery for public story information and media files
These providers process only the information needed for their function and are governed by their own privacy terms. Nightjar does not sell personal information and does not share information for cross-company advertising.
7. Notifications
If you grant notification permission, Nightjar schedules bedtime and morning reminders locally on your device. The reminder text and your chosen schedule are not sent to an advertising network.
8. Website data
This website does not run advertising or product analytics and does not set first-party tracking cookies. Like most websites, the hosting provider and font-delivery provider may receive ordinary technical request data such as IP address, browser type, and request time for security and delivery.
9. Your choices and deletion
- Turn product analytics off from Nightjar’s privacy control.
- Delete individual jars or use the in-app data controls to delete Nightjar data.
- Turn iCloud Backup off or delete Nightjar’s backup from iCloud in the app.
- Change Health and notification permissions in iPhone Settings.
- Delete the app to remove its local data from that device. This does not by itself cancel an App Store subscription or delete an existing iCloud backup.
Because Nightjar has no account tied to your identity, I generally cannot locate app data using your name or email. Contact [email protected] with any privacy request or question.
10. Security
Nightjar uses platform security controls and on-device encryption for sensitive fields. No system is perfectly secure, but the app is designed to minimise collection and keep private content under your control.
11. Children
Nightjar is not directed to children under 13, and I do not knowingly collect personally identifiable information from children. If you believe a child has provided such information, contact [email protected].
12. International processing
Service providers may process limited technical and pseudonymous information in countries other than yours. Their contractual and legal safeguards apply where required. Your private Nightjar backup remains associated with your personal Apple iCloud account.
13. Changes to this policy
I may update this policy as Nightjar changes. The effective date above will show the latest revision. Material changes will be communicated in the app when appropriate.
14. Contact
Questions or requests about this policy can be sent to [email protected] or to Jugal Mistry on X.
