HELLO CETUS
Privacy Policy
Hello Cetus is a mobile astronomy and calendar app operated by Waitcle. Much of the app state stays on your device, but the app also uses permissions, advertising and consent tools, NASA moon-image endpoints, browser links, and email-based support flows. This page explains what the app stores, what third parties may be involved, how long information may be kept, and how privacy requests can be made.

About Hello Cetus
Hello Cetus is an astronomy and calendar app. Depending on the release and device, it may include moon-calendar views, today summaries, planet-angle views, astronomy event reminders, date-based notes, optional location-aware sky features, and region or city settings for more relevant calculations.
The app is designed so that much of the information connected to ordinary use stays on your device rather than inside a mandatory account system. At the same time, some flows may use advertising and consent frameworks, open your browser, open your email app, talk to device settings, or request data from external source pages when you choose those actions or when the app needs them.
Operator and Scope
Hello Cetus is operated by Waitcle. This Privacy Policy applies to the Hello Cetus mobile app, the legal pages published for the app at hellocetus.com, and support or privacy-request emails sent to [email protected].
This policy does not replace the privacy terms of third-party services such as Google advertising systems, NASA source pages, Apple or Google platform services, your browser, your email provider, or other apps that open from Hello Cetus.
What Stays on Your Device
The current app experience uses on-device storage for many of the settings and inputs that make the app feel personal and persistent across launches.
The app stores settings such as language, theme, onboarding completion, launch count, region defaults, visibility filters, sunrise or sunset display preferences, and astronomy reminder state so the experience stays consistent across launches.
If you write short memos for calendar dates, those notes are stored locally on your device as part of the app experience.
If you choose a region or precise city mode, the app may store country, city, time zone, latitude, and longitude values used for astronomy and calendar calculations.
If you refresh and save GPS-based sky data, the app may store latitude, longitude, a saved timestamp, and a local time zone value on your device.
The app may save local values such as astronomy notification state, whether permission prompts were already shown, whether the iPhone tracking prompt was already handled, and related preference flags.
Hello Cetus does not currently require account sign-in for ordinary use of the core app experience.
Permissions the App May Request
Some features only work well if you allow certain device permissions. These permissions are optional unless the feature itself depends on them.
The app may request location access for optional astronomy features that depend on your current position, such as sky angle or local observation views.
The app may request notification access if you turn on astronomy reminders. These reminders are used to alert you before supported astronomy events.
If you enable astronomy reminders, the app may request exact alarm capability on supported Android devices so reminders can fire close to their intended time.
The app includes Google Mobile Ads and consent tools on supported Android and iPhone devices. On iPhone, the app may also ask for Apple tracking permission. The current in-app text explains that, if allowed, app and web activity may be used for more relevant offers and ads and for ad performance measurement.
Ads and Tracking Choices
The current app build includes advertising-related components. That means some devices may see consent screens, privacy-choice screens, app open ads, or iPhone tracking permission prompts depending on platform, region, launch count, and consent status.
Hello Cetus currently includes the Google Mobile Ads SDK and consent-management flows used to decide whether ads can be requested on supported devices and in supported regions.
Based on the current app logic, app open ads may be requested on supported Android or iPhone devices after at least three launches, subject to consent status, platform support, and ad availability.
The app can show an ad privacy choices screen and EEA, UK, or Switzerland privacy-rights information. Those flows are tied to applicable regional law, platform behavior, and Google consent requirements.
External Requests and Third Parties
The app may request moon-image metadata from NASA SVS Dial-A-Moon. Those requests are sent over the network when the app needs current moon imagery information.
If ads or consent flows run on your device, Google or related advertising services may process consent status, advertising identifiers, device or app signals, and ad interaction data under their own terms and privacy policies.
When you open legal pages, contact support, manage permissions, or open app-store tools, your browser, email app, operating system, app store, or related provider handles that part of the interaction under its own rules.
When you use those external features, the related third party may receive the request and the technical information normally involved in handling that interaction. Those services operate under their own policies, not this Privacy Policy.
How Information Is Used
- To show moon, sun, planet, and calendar content in the format, region, language, and time zone you selected.
- To calculate local event times and location-sensitive astronomy views when you choose precise city or GPS-based features.
- To save notes, region choices, saved GPS values, alert preferences, and app settings between sessions.
- To schedule local astronomy notifications, including reminders about supported events roughly one hour before start.
- To run consent, ad-privacy-choice, advertising, and iPhone tracking flows when supported by your device, platform, and regional rules.
- To prepare support, feature-request, and privacy-request emails with app name and version details when you choose those contact flows.
- To load current moon-image metadata and open external legal, support, settings, or source pages when you ask the app to use those resources.
Retention and Deletion
Because Hello Cetus does not currently require a normal user account, much of the information connected to ordinary use stays on your device until you change it, overwrite it, clear app data, or uninstall the app. That includes stored notes, region and city selections, saved GPS values, theme or language settings, and local reminder state.
If you contact us by email, we may retain your email address, message contents, and related support history for as long as reasonably necessary to reply, troubleshoot, document the request, comply with law, or resolve disputes. Third-party providers such as Google, Apple, NASA, browsers, email providers, or app stores may keep their own logs or records according to their own retention rules.
Security
We use reasonable steps appropriate to the app's structure to protect information connected to Hello Cetus. Much of the app state is kept in the device sandbox and relies on your operating system's security, permission model, and lock-screen protection.
No method of storage, transmission, or platform integration is perfectly secure. If you send us an email or use third-party advertising, browser, email, or platform services, those systems apply their own security practices and risks.
Regional Rights and Requests
Users in the EEA, UK, and Switzerland may have rights under applicable law to request access, correction, deletion, restriction, objection to personalized advertising, consent withdrawal, and data portability. The app currently includes privacy-rights guidance and ad privacy choices for supported regions.
To make a privacy request, contact [email protected] and include the app name, version, your region if relevant, and the request type if possible. Support, feature-request, and privacy-request flows in the app may help prefill those details in your email client.
Your Choices
You can manage many Hello Cetus privacy choices directly from your device and from within the app.
- Turn notifications on or off in the app or device settings.
- Allow or deny exact alarm access on supported Android devices.
- Grant, deny, or revoke location access from device settings.
- Open and update ad privacy choices when those options are available.
- Change iPhone tracking permission from Apple settings.
- Delete app notes, saved GPS values, or clear app data stored on your device.
- Stop using the app at any time by uninstalling it.
