Privacy Policy

Effective: 29 August 2026　·　Last updated: 30 August 2026

UnivMap (the “App”) collects no data, transmits no data, and stores no personal information. The App has no account or registration mechanism, operates entirely offline, makes no network requests while running, and everything you do in it stays on your own device. This policy describes how the App handles data and forms part of the Terms of Use.

1. The App collects nothing

There is no registration or sign-in mechanism, and the App never asks for your name, email address, telephone number, or any identifier. It requests no location permission, and neither requests nor accesses your contacts, camera, microphone, photo library, or health data. It integrates no analytics, event-tracking, advertising, or crash-reporting service, reads no advertising identifier, performs no cross-app tracking, and uses no cookies or cross-site tracking technology of any kind. All astronomical data is compiled into offline files during development and ships with the App onto your device; at runtime the App does not query, download from, or report to any server.

2. Settings stored on your device

Using the platform’s standard preference storage, the App remembers the map style, language, projection, and drop-line setting you selected, along with the “Home” and “Work” shortcuts you assigned, your recent searches, and your saved places. What is stored in each case is an identifier of an object on the star map or a preference about the interface; none of it identifies you. This data is written only to local storage on your device, is never transmitted anywhere, and is not accessible to the Developer.

3. About “Home” and “Work”

The home screen provides two shortcuts labelled Home and Work, following the convention of ordinary map apps, but they bear no relation to where you actually live or work. Each shortcut stores the identifier of an object on the star map — Earth, the Moon, Mars, Alpha Centauri, and so on. The App requests no location permission and never goes online, and therefore cannot determine your real-world location.

4. Deleting this data, and device backups

Clearing your search history, removing a saved place, or resetting a shortcut inside the App deletes that entry from your device; uninstalling the App deletes all of the above with it, and no copy remains anywhere. If you have enabled iCloud Backup or Google device backup, the operating system’s backup mechanism may include these settings in your device backup; such backups are handled and encrypted by Apple or Google under their own privacy policies and are not accessible to the Developer, and you can exclude the App from backup in your system settings.

5. App stores

The App shares no data with any third party. It is, however, obtained through the Apple App Store or Google Play, and those platforms collect download, purchase, and crash statistics under their own policies; that is platform behaviour and falls outside the scope of this policy. See the Apple Privacy Policy and the Google Privacy Policy.

6. Children’s privacy and your rights

The App is suitable for all ages and collects no personal information from any user, including children under 13, and is therefore compliant by design with the U.S. Children’s Online Privacy Protection Act (COPPA) and equivalent regulations elsewhere. The EU General Data Protection Regulation (GDPR), the UK GDPR, and the California Consumer Privacy Act (CCPA/CPRA) grant you rights of access, rectification, erasure, and portability, and the right to opt out of the sale of personal data; because the App has never collected or held any personal data, the Developer holds nothing to access, rectify, port, or erase, and personal information has never been sold or shared and will not be. The settings on your device can be deleted by you at any time.

7. Sources of astronomical data

The positions, distances, and motions in the App are offline snapshots taken from the public databases of NASA, ESA, and the Centre de Données astronomiques de Strasbourg (CDS); that data belongs to those institutions and the App merely presents it. This App is a personal project and is not affiliated with, sponsored by, or endorsed by NASA, ESA, JPL, CDS, or any of the institutions named above.

8. Changes to this policy, and contact

If the App’s behaviour changes — for instance if any networked feature is added — this page will be updated and the “Last updated” date above revised before that feature ships. Questions about this policy: [email protected]
