Privacy Policy · Daily Earth View

CloudEx Inc. ("we", "us", or "our") operates the "Daily Earth View" app (the "Service"). This Privacy Policy explains what information we collect, how we use it, and the choices available to you. By using the Service, you are deemed to have agreed to the practices described in this Policy.

1. Our Core Principle

Daily Earth View shows you the Earth as satellites see it: the whole Earth photographed by NASA's DSCOVR / EPIC camera, daily satellite imagery on a zoomable map (NASA GIBS, any day since 2000), comparisons between dates and across decades (Landsat since 1972 and Copernicus Sentinel-2 since 2016), and natural events such as wildfires, volcanoes, and storms (NASA EONET). It also offers time-lapses, an ambient mode, wallpapers, home-screen widgets, and alerts for natural events near the places you choose. All of this imagery is public data that the app downloads directly from public services (Section 2).

There is no account, no sign-up, and no login, and the app contains no analytics and no tracking. Specifically, we never collect any of the following:

Your location. The app has no location permission and never reads GPS or your device's location. Your home and favorite places are chosen by you on the map or by searching for a place name.
Your home, your favorite places, or a history of the places and dates you view
The images and videos you save
Your name, email address, phone number, or contacts

Your home and favorite places are stored only on your device. Even the alerts for natural events near them are worked out on your device, and your places are never sent anywhere for this purpose (Section 3.2).

2. How the App Gets Imagery

All imagery and event data in the app come from public services. The app connects to them directly, uses no API keys, and sends no user identifiers. To each service it sends only what is needed to fetch the imagery for what you are looking at: the map area (tile) and the date, or the place you are comparing. When the app shows imagery for your home or a favorite place, the request likewise contains only the map area and the date. As with any request to a web server, the server also receives your device's IP address as part of the connection. The app identifies itself to these servers by its name, version, and website (the User-Agent); this contains no personal data.

NASA GIBS / Worldview (gibs.earthdata.nasa.gov) — daily satellite imagery and overlays for the map, and fire detections.
NASA EPIC (epic.gsfc.nasa.gov) — photos of the whole Earth taken from the DSCOVR spacecraft.
NASA EONET (eonet.gsfc.nasa.gov) — the list of natural events.
Microsoft Planetary Computer (planetarycomputer.microsoft.com) — Landsat and Sentinel-2 imagery for the decades comparison. The area of the place you compare is sent so that the service can build the mosaic for each year.
Wikidata / Wikipedia (query.wikidata.org, *.wikipedia.org) — a short summary of a volcano, shown only when an article exists in your device's language.
Android Geocoder (the place-name service built into Android, provided by Google on most devices) — when you search for a place, the text you type is sent to find it; to show the name of the place on the map, the coordinates of that place are sent.

Background updates: About every 3 hours, the app refreshes the widgets, the daily wallpaper, and the alerts in the background, using the same services. You can limit these updates to Wi-Fi in the settings. The daily wallpaper is changed while the screen is off.

Tapping a source or report link (for example, the source report of an event, or a Wikipedia article) opens it in your browser. From then on, that website's own privacy policy applies.

3. Information We Collect

3.1 Information Collected Automatically

Anonymous crash reports: Via Firebase Crashlytics. When the app crashes, we collect the stack trace, device model, OS version, app version, and a random identifier that Firebase assigns to each installation of the app. This does not include personally identifiable information, your places, or any images.
Purchase information: We use purchase tokens issued by Google Play to verify your one-time "Premium" purchase. We never receive any payment information such as credit card numbers.
List of our other apps: To show our other apps, the app downloads their names, descriptions, and icons from our content server (a static list hosted on Cloudflare Pages). The request contains no personal data from the app. As with any request to a web server, the server receives your device's IP address as part of the connection.

Crash reports and purchase tokens are the only information that reaches us. We keep no account, no history of the places you view, and no imagery on our side.

3.2 Information Stored Only on Your Device

Your home and favorite places: The name and coordinates of each place, and the last position of the map, are stored on your device.
App settings: The map view and overlays, units (km / miles), the Wi-Fi-only setting, your wallpaper and widget choices, the alert distance (50–2,000 km) and event types, the theme, and similar settings are stored on your device.
Downloaded imagery and data: Imagery and data the app has downloaded are kept in the app's cache, which you can clear from the settings. The images drawn for the widgets and the IDs of the events you have already been notified about are also kept on your device.
Alerts for natural events nearby (Premium, off by default): The app downloads the public list of natural events and compares the locations of the events with your home and favorite places on your device. Your places are never sent anywhere for this.
Images and videos you save: They are saved to your device's gallery, in Pictures/DailyEarthView (on Android 10, videos may be saved to Movies/DailyEarthView). Each saved image carries a credit for the imagery (for example, NASA or Copernicus) in its corner. Files in the gallery can be seen by other apps that you have allowed to access your photos and videos.
Android backup: If backup is turned on in your device settings, Android may back up the app's settings, including your home and favorite places, to your own Google account and copy them to a new phone. Cached imagery, thumbnails, exported files, the map cache, and one settings file that is used only on the device are excluded. This is handled by Android; we have no access to it.
When you uninstall: Uninstalling the app or clearing its data deletes everything in the app's own storage, including your settings, your home and favorite places, and the cache. Images and videos saved to the gallery are not deleted and remain until you delete them.

3.3 Information We Explicitly Do Not Collect

Your location (the app has no location permission)
Your home, your favorite places, or a history of the places and dates you view
The images and videos you save
Your name, email address, phone number, or contacts (the app has no account or sign-up)
App usage analytics or your device's advertising ID (the app contains no analytics and does not use the advertising ID)
The contents of your screen or of other apps

3.4 Permissions the App Requests and Their Purposes

Daily Earth View requests only the following permissions and uses them only for the stated purposes:

Internet (INTERNET) — Downloads all imagery and data from the services in Section 2. Also used for Google Play purchase verification, in-app reviews and in-app updates, downloading the list of our other apps, showing this privacy policy in the app, and sending crash reports.
Network status (ACCESS_NETWORK_STATE) — Checks whether your device is online and whether it is on Wi-Fi, for the setting that limits background updates to Wi-Fi.
Notifications (POST_NOTIFICATIONS, Android 13+) — Lets you know about new natural events near your home or favorite places. Used only for the alerts (Premium), which are off by default.
Run at startup (RECEIVE_BOOT_COMPLETED) — Schedules the background updates of the widgets, the daily wallpaper, and the alerts again after your phone restarts.
Set wallpaper (SET_WALLPAPER) — Sets the wallpaper when you choose "Set as wallpaper", and changes the daily wallpaper (Premium).
Google Play billing (com.android.vending.BILLING) — The one-time Premium purchase through Google Play.
Storage (WRITE_EXTERNAL_STORAGE, Android 9 and earlier only) — Saves images and videos to the gallery. Not requested on Android 10 and later.

The app does not request access to your location, camera, microphone, contacts, phone, SMS, or calendar, and does not use accessibility services, display over other apps, or access the list of all apps on your device.
