This policy covers the Moon Lunation app for iPhone, iPad and Mac, published by TraLand.com (“we”, “us”). Questions: support@traland.com.
Nothing. There is no account or sign-in, no analytics, no crash reporting, no advertising and no
attribution SDK of any kind. The app ships a PrivacyInfo.xcprivacy manifest declaring
NSPrivacyTracking = false with every collected-data category empty, and our App Store
privacy answers are Data Not Collected across the board.
The app contains no networking code of its own. No URLSession, no network
entitlement, no remote configuration, no update check. All the astronomy is computed on your device,
including the first time you open it. In-app purchases are handled entirely by Apple’s StoreKit
framework, part of iOS, iPadOS and macOS. Apple processes the payment and tells the app only whether the
purchase is unlocked; we never see your payment details, Apple ID or any personal information.
Apple’s privacy policy applies to that exchange.
So this is not a policy of restraint about data we could collect. The app has no way to send us anything.
The app never asks for location and has no location features. It will not prompt you for permission, because it has nothing to do with the answer.
The 2009 version of this app had a fixed city list. That has been removed entirely. All times shown are geocentric — computed for the centre of the Earth rather than for wherever you are.
No user data. No history, no saved dates. On iPhone and iPad the app stores no data of its own. On the Mac, the app stores one setting, whether the Moon is shown in the menu bar, on your Mac only. Nothing else is stored.
The old app stored data in a file called moondb.sqlite, and on a device that has carried
the app forward for years that file may still exist.
Moon Lunation never opens it. It does not read it, migrate it, or report anything about it. This is a deliberate written requirement of the rebuild, not an oversight: the app has no reason to look inside a file from the old version, so it does not.
It is also left exactly as found, rather than cleaned up — a decision that was taken and recorded, not arrived at by nobody deciding. What settled it is worth knowing, because it means the file is not what it looks like: there is nothing of yours in it. The 2009 app shipped a 153 KB reference database inside itself and copied it into place on first launch, and its code contained no statement capable of writing to it. All 1,624 rows are data that shipped with the app in 2009 — 149 cities, 1,453 phase entries and 22 supporting rows. Deleting it would protect no personal data, and would add the only file-modifying code path to an app that otherwise writes nothing.
The Moon surface is the public-domain CGI Moon Kit from NASA's Scientific Visualization Studio, reprojected offline and bundled with the app. It is shipped inside the app, not downloaded, so displaying it involves no request and tells nobody anything about you.
The app collects nothing. Until Moon Lunation was released, its page on this website carried a form for asking to be told when it shipped; that form has now been removed. What the website itself collects is covered by its own policy at traland.com/privacy.
No data is shared with anyone, because the app collects none.
Moon Lunation contains no advertising, no accounts and no user-generated content, and it collects nothing from anyone, of any age. It offers one optional in-app purchase, Moon Lunation Pro, which unlocks the 3D Solar System; it is a one-time purchase, never a subscription.
If the app’s data handling ever changes, this page changes with it and the date at the top is updated.
