Privacy Policy

Effective date: October 7, 2026

Moon Phase helps you explore the Moon from a selected location and time. This policy explains how the app uses location information, stores settings, and requests moonrise and moonset data.

Location and date information

If you allow location access, Moon Phase uses your device’s location to display the Moon’s appearance and retrieve information for that location. You can also search for and select a location manually without granting device-location permission.

The app calculates phase, illumination, altitude, and orientation on your device once the location and its time zone are known. These calculations do not require a request to WeatherAPI.

Services used by the app

Moon Phase uses the selected location’s latitude and longitude and the requested date to retrieve moonrise and moonset information from WeatherAPI.com. This may be your device’s location or a location you selected manually. Depending on the app version, requests are sent directly to WeatherAPI or through our astronomy service at moonphase.kofther.com. A direct request exposes your IP address to WeatherAPI. When our service is used, our hosting provider receives your IP address and the requested coordinates and date; WeatherAPI receives the requested coordinates and date and our server’s IP address.

Our astronomy service caches location-specific responses for up to 24 hours to reduce repeated requests. Rate-limit records use a keyed hash of the connecting IP address and expire after approximately two minutes. Expired cache and rate-limit records are removed during subsequent requests. Standard hosting security and access logs may also be retained by our hosting provider. The service does not maintain an account or a location history associated with your identity.

Location search and location or time-zone resolution use Apple’s MapKit and Core Location services. Search text and information needed to resolve a location may be processed by Apple.

These services operate under their own privacy policies. See WeatherAPI’s privacy policy and Apple’s privacy policy. Moon Phase does not control their retention practices.

Information saved on your device

The app saves your preferences, including notification and appearance settings. A manually selected location can be saved with its name, coordinates, and time zone so it can be restored when you reopen the app. Matching location and time-zone information is also saved to support offline calculations.

Moonrise and moonset responses are cached on your device by date, location, and time zone. Cached entries are treated as fresh for 24 hours; expired entries are pruned and are not displayed as saved values.

Notifications

Lunar-event reminders are scheduled locally on your device through iOS. They do not use a remote push-notification server. You can change notification preferences in Moon Phase and control notification permissions in iOS Settings.

Advertising and accounts

Moon Phase does not require an account and does not include advertising or third-party usage-analytics tracking. We do not sell your personal information or use your location for advertising.

Support communications

If you email support, we receive your email address and the information you choose to include. We use that information to respond to your request. Please do not send passwords or other sensitive information.

Website analytics and cookies

With your permission, this website uses Google Analytics, provided by Google, to understand visits and improve the site. It can measure pages viewed and interactions such as outbound links when those measurements are enabled. This website analytics integration does not add analytics to the Moon Phase iPhone app.

Google Analytics uses cookies and processes information about your browser, device, and activity on the website. When you accept analytics, your browser connects to Google to send measurement data. Advertising features and Google Signals are disabled in this website’s configuration.

Google Analytics is not loaded before you choose Accept. If you choose Decline, the site remains usable without analytics. Your choice is saved in your browser’s local storage so the website can remember it.

You can reopen your choices using Analytics preferences in the footer. Declining after accepting stops future analytics collection on the website. It does not erase data already sent to Google. Previously stored analytics cookies may remain until you clear them using your browser’s settings.

Google processes analytics information under its own policies. See Google’s privacy policy. This website does not use analytics for personalized advertising.

The hosting and email providers may process routine connection information and server logs to operate their services.

Your choices

You can deny or revoke location access in iOS Settings and use manual location selection instead. You can disable notifications in the app or in iOS Settings.

Deleting the app removes its local app data from that installation. Any device backups and information already processed by external services are governed by those services’ settings and policies.

Children’s privacy

Moon Phase is not specifically directed at children. We do not knowingly collect personal information from children through support communications.

Changes to this policy

We may update this policy when the app or its services change. The current version will be available on this page with its effective date.
