Privacy Policy

This Privacy Policy explains how the StellarVana iOS app and the stellarvana.com website (the “Services”) handle information. These pages are operated by the operator of stellarvana.com. “We,” “us,” and “our” refer to the operator of stellarvana.com.

This page is a consumer-facing description for App Store and website use. It is not legal advice and has not been certified by counsel for every jurisdiction.

1. Who this applies to

This Policy applies to visitors of stellarvana.com and users of the StellarVana iOS app. Apple has its own privacy practices for App Store purchases and Apple ID.

2. No StellarVana account

StellarVana does not require you to create a StellarVana account, email, or password on our servers. We do not operate a StellarVana backend that stores your location, pins, light log, or sky settings for cloud inference. There is no StellarVana iCloud, Continuity, or App Group sync in this version.

3. Information on your device

Depending on the features you use, the app may store on your iPhone:

• Observer location (When In Use GPS, or latitude and longitude you enter manually)
• Pins, light-log entries (observed / not seen, date, place, optional note), and time bookmarks
• Sky-display preferences (magnitude cap, constellation lines, night vision, hold-up, and similar)
• Observe-alert choices if you subscribe and opt in (all default off)

Location is used to draw the sky above your horizon, Tonight planning, local eclipse geometry, and ISS teaser. You can skip GPS and set coordinates in Settings. StellarVana does not use HealthKit. Pins and logs are app content, not health records.

4. How we use information

We use information to:

• Draw the live star map, instruments, Search, and related features on your device
• Remember preferences you set in the app
• Respond to support emails you send us
• Unlock Premium features after Apple confirms a subscription
• Comply with law and enforce these terms and Apple’s Standard EULA

We do not sell your personal information. We do not use your sky or observation history for third-party advertising. We do not use an advertising identifier. We do not build a natal chart, houses, or “what this means for you” profile from your location.

5. Optional network (ISS TLE)

ISS positions use SGP4 from a two-line element set. A bundled TLE ships in the app so the map works offline. Optionally, the app may refresh that TLE from Celestrak (NORAD 25544) and cache it on disk. Age is shown in Settings. That fetch hits Celestrak only — no StellarVana tracking server and no extra query parameters that identify you to us.

6. On-device wording

Sky positions and Observe rank order are deterministic on this iPhone (VSOP87, Meeus, catalogs, SGP4). If you subscribe, optional on-device language models may polish captions after those facts, with an authored-card fallback. Wording stays on the device. It is not uploaded to a StellarVana server and does not invent visibility.

7. Observe alerts (Premium, off by default)

Optional local notifications for ISS visible passes, pinned rise/set, Tonight top-3, meteor peak, and local eclipse use Apple’s notification permission only if you turn the master switch on. All types default off. Alerts are authored reminders, not promotional nudges.

8. Purchases (StoreKit)

Optional Premium is an auto-renewable subscription processed by Apple. We receive limited purchase or entitlement signals needed to unlock paid features (for example, subscription status). We do not receive your full payment card number. Apple’s privacy policy applies to payment data.

9. Analytics

StellarVana does not send usage analytics to a StellarVana server. We do not operate a third-party product-analytics SDK in the app. If Apple shares crash or diagnostic data with us under your device settings, we may use that to fix bugs. The marketing website may keep standard hosting logs (IP address, browser type, pages visited) for security and basic operations. If we add website analytics or cookies later, we will update this Policy and, where required, provide consent controls.

10. Support email

If you email support@stellarvana.com, we receive the address and message you send (and any attachments) so we can reply. Include your iOS version and what you were trying to do. Do not send health information or other sensitive content you would not want in an email inbox.

11. Website

stellarvana.com is a marketing and legal site. It does not host your in-app sky or observation log. Hosting logs may include IP address, user agent, and requested URLs.

12. Sharing

We share information only when:

• You choose to share (for example, the system share sheet)
• Apple processes purchases or device services you enable
• Celestrak receives a TLE refresh request if that optional fetch runs
• A service provider assists website hosting or email under confidentiality obligations
• Required by law, legal process, or to protect rights and safety
• In a merger, acquisition, or asset transfer (with notice where required)

13. Retention

Data you store in the app generally remains until you delete it or uninstall the app. Support emails are retained as long as needed to resolve your request and meet legal obligations.

14. Children

The Services are not directed to children under 13 (or the minimum age in your region). We do not knowingly collect personal information from children. If you believe a child has provided data, contact us and we will take appropriate steps.

15. Security

We use reasonable administrative and technical measures appropriate to a local-first app and a marketing website. No method of storage or transmission is completely secure. Use a device passcode and keep your OS up to date.

16. Your choices and rights

Depending on your location, you may have rights to access, correct, delete, or export personal information, or to object to certain processing. For app data on your device, you can clear pins and logs in the app or uninstall. For support-related data or other requests, email support@stellarvana.com. You may also adjust platform privacy settings (location, notifications, analytics, App Tracking) on your device.

17. International users

If you access the Services from outside the country where the Services are operated, your information may be processed where we or our providers operate, subject to applicable law. Optional Celestrak requests follow that provider’s processing.

18. Changes

We may update this Policy from time to time. We will revise the “Last updated” date and, for material changes, provide additional notice where appropriate.
