PRIVACY POLICY — RE LUMINARY
Last updated: 21 April 2026
RE LUMINARY ("the app") is developed and published by Andrés Matas Baena under the brand Resonancia Éter ("we", "us", "our"). This Privacy Policy explains how the app handles information when you use it.
1. INFORMATION WE COLLECT
RE LUMINARY collects only the following information, and only locally on your device:
- Location data (latitude and longitude): required to calculate accurate solar events (sunrise, sunset, golden hour, blue hour, twilight phases, sun position) for your specific geographic position.
The app does NOT collect:
- Your name, email, phone number or any personally identifiable information
- Your contacts, photos, camera data or microphone data
- Device identifiers used for advertising (IDFA)
- Browsing history, app usage data or analytics
- Payment information
2. HOW WE USE THE INFORMATION
Location data is used exclusively to perform astronomical calculations on your device. The app uses standard NOAA solar position formulas, executed entirely on your iPhone. Your location is never transmitted to any server, never stored in any cloud, and never shared with any third party.
3. DATA STORAGE
All data processed by the app (including your location, date selections and any preferences) is stored locally on your device. We do not operate any server or backend infrastructure that receives user data.
If you uninstall the app, all data is removed from your device.
4. DATA SHARING
We do not sell, rent, trade or share any user information with third parties. We do not integrate advertising networks, analytics SDKs or tracking services.
5. THIRD-PARTY SERVICES
RE LUMINARY does not integrate any third-party service that collects user data. The app does not use Firebase, Google Analytics, Facebook SDK, AdMob, or any similar service.
The app may use Apple's standard iOS frameworks (CoreLocation, WidgetKit, ActivityKit) which operate entirely on-device under Apple's privacy rules.
6. CHILDREN'S PRIVACY
RE LUMINARY is not directed to children under 13. We do not knowingly collect any information from children under 13. Since the app does not collect personal data from anyone, compliance with COPPA is inherent to the app's design.
7. YOUR RIGHTS
Because we do not collect, store or process any personal data on our servers, there is no user data for us to access, modify or delete on your behalf. All data stays on your device at all times, under your exclusive control. You can remove all app-related data by uninstalling the app.
Under GDPR (European Union) and CCPA (California), you have the right to access, rectify, delete or restrict processing of your personal data. Because we do not process personal data, these rights are automatically satisfied by the app's design.
8. SECURITY
Since no data leaves your device, the security of your information depends on your device's own security (passcode, Face ID, Touch ID, encrypted iCloud backup if enabled by you).
9. 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 "Last updated" date. Material changes will be communicated through an app update release note.
