Lunaday - Privacy Policy

Effective Date: November 13, 2026

1. Overview

Lunaday: Moon Phase Widget is an app by Time Design LLC for Android. It shows the current Moon phase, moonrise and moonset, upcoming full and new moons and eclipses, in the app and in Home Screen widgets.

The app works without an account. Your data stays on your device and is not sent to Time Design LLC. This policy explains what the app stores, which permissions it may ask for, and which network connections it makes.

2. Data We Collect

We do not collect personal data. Time Design LLC does not operate servers that receive anything from Lunaday, and the app contains no analytics, advertising, crash-reporting or tracking SDKs.

3. Data Stored on Your Device

The following is stored only on your device, inside the app:

  • App preferences and widget settings.
  • Your city: either the one you pick from the built-in list, or the nearest city to your approximate location (see Section 4). Only the city is kept, not your exact position.
  • Reminder settings.
  • Your Pro status (a cached copy of what Google Play reports).

4. Permissions

Every permission is optional and used only for the related feature. Data obtained through these permissions never leaves your device. You can change permissions at any time in your device settings.

  • Approximate location (optional). Only when you tap the button to use your location, the app reads your approximate location once, rounds it to the nearest city from a list built into the app, and keeps only that city — to calculate moonrise, moonset and the tilt of the crescent for your place. The location is not stored, tracked in the background or sent anywhere. Instead of sharing your location, you can choose a city by hand.
  • Notifications (optional). Used for reminders about full moons, new moons and eclipses that you turn on. These reminders are scheduled and shown by the app on your phone; there are no push notifications from a server.
  • Run at startup. Used only to restore your reminders and refresh widgets after the phone restarts.
  • Home Screen widgets. Widgets show the Moon phase and times on your phone's screen; the data stays on the device.
  • The app does not ask for contacts, calendar, messages, camera, microphone or photos.

5. Network Connections

Lunaday makes no network requests of its own: Moon phases, rise and set times and eclipses are calculated on the device, and the Moon image and city list are built into the app. The only connections are made by Google Play: for the in-app purchase (see Section 6) and for the optional in-app rating prompt, which is shown and handled by Google (Google Play In-App Review) under the Google Privacy Policy. Links you tap in the app (this privacy policy or the app's Google Play listing) open in your browser or in Google Play, and “Contact us” opens your email app with a message to our support address; we receive only what you choose to send.

6. In-App Purchases

Lunaday Pro is a one-time purchase sold through Google Play and processed by Google (Google Play Billing) under the Google Privacy Policy. We never receive your name, Google account, card or billing details — the app only receives the status of your purchase, which is restored from Google Play.

7. Tracking and Advertising

  • No tracking and no analytics.
  • No advertising and no Advertising ID.
  • No data is sold or shared with third parties.
  • No account, no sign-in, no contact list access.

8. Backups

The app's settings, including the city you chose, may be included in Android backup to your Google Drive when you have it turned on; that backup is handled by Google and controlled by you, not by us.

9. Third-Party Content

The Moon texture comes from NASA's Scientific Visualization Studio (public domain). City names and coordinates come from GeoNames (CC BY 4.0). Both are built into the app; using them does not send any data from your device.

10. Children's Privacy

Lunaday is not directed at children under 13 and does not knowingly collect any information from them.

11. Data Retention and Deletion

The app's data stays on your device until you uninstall the app, which removes it. Because we hold no copy of your data, there is nothing for us to delete on our side.

12. Changes to This Policy

We may update this policy when the app changes. The effective date at the top shows the latest version.
