AS2AI – Universe Explorer

Privacy Policy

Effective date: October 11, 2026

1. Who we are

This Privacy Policy applies to AS2AI – Universe Explorer ("AS2AI", "we", "us", or "our") and the services used by the Android app. AS2AI is an astronomy and sky-exploration app designed to provide observing recommendations, interactive sky content, and related educational experiences.

Privacy questions can be sent to quangtrandn93@gmail.com.

2. Information AS2AI handles

Observing location

AS2AI can use your approximate foreground device location when you choose the current-location option. The current Android release requests coarse location permission only. You can also select a place manually or keep the default observing location without granting location permission.

Coordinates used for observing, together with timezone, language, and request time, are sent over HTTPS to the AS2AI service when needed for features such as Tonight recommendations, sky-map calculations, and location-aware observing context. The backend processes the requested coordinates to generate results and stores privacy-reduced regional records using coordinates rounded to two decimal places for plan snapshots and anonymous service-usage records. AS2AI does not intentionally keep a history of exact GPS trails.

Place search

When you type a city or place into location search, the search text is sent to the Open-Meteo geocoding service so AS2AI can return matching place suggestions.

App preferences and local data

AS2AI stores app settings locally on your device, including the selected observing location, language, onboarding state, local feature-preference signals, and advertising frequency counters. Android app backup and device-transfer backup are disabled for AS2AI app-private data.

Saved images

Images saved by AS2AI are stored on your device. Existing Sky Moment images and related local metadata remain local unless you explicitly choose to share them through Android. Sky Moment creation is currently hidden from the primary app journey, but previously saved images can remain available in the Library.

Advertising, device data, and consent

AS2AI uses Google Mobile Ads (AdMob) and Google's User Messaging Platform (UMP). Depending on your region, consent choices, and device settings, Google may process information such as IP address, device or advertising identifiers (including the Android Advertising ID when available), app interactions, and diagnostic information for advertising, analytics, fraud prevention, security, and compliance purposes.

AS2AI does not intentionally pass permission-derived observing coordinates to AdMob. Google may independently estimate an approximate location from information such as an IP address in accordance with Google's own privacy practices.

Accounts

The current Android release does not require you to create an account or sign in to use its core functionality.

3. How we use information

AS2AI uses the information described above to:

  • calculate what is visible from your observing location;
  • provide Tonight recommendations and sky-map context;
  • localize the app and remember your preferences;
  • operate, measure, and limit advertising where enabled;
  • maintain service reliability, security, and abuse prevention; and
  • improve regional observing recommendations using privacy-reduced records.

AS2AI does not sell your personal information.

4. Third-party services

AS2AI may rely on the following services:

  • Google Mobile Ads and UMP for advertising, consent management, analytics related to advertising, and fraud prevention. See Google's Privacy Policy.
  • Open-Meteo for place-name geocoding when you use manual location search. See Open-Meteo's terms and privacy information.
  • AS2AI hosting and infrastructure providers to deliver API requests and operate the service. Those providers may process ordinary network and security logs as part of hosting the service.

5. Data retention and deletion

Local app preferences remain on your device until you clear AS2AI app data or uninstall the app. Saved images remain on your device until you delete them.

The AS2AI backend stores privacy-reduced observing snapshots and anonymous usage records, including rounded regional coordinates, for service operation and product improvement. The current Android app does not create a user account, so these records are not intentionally stored under a user profile.

You may contact us at quangtrandn93@gmail.com with a privacy or deletion request. Because the current app does not associate anonymous regional records with an account, we may not be able to identify a particular backend record as belonging to a specific person.

6. Security

Production app-to-service traffic is configured to use HTTPS. AS2AI stores local preferences in Android app-private storage and disables Android cloud backup for app-private data. No method of electronic storage or transmission can guarantee absolute security.

7. Your choices

You can control several privacy-related settings directly:

  • deny or revoke location permission in Android settings;
  • use a manual or default observing location instead of device location;
  • use the in-app Privacy options control when Google UMP requires it; and
  • manage Android and Google advertising privacy settings on your device.

8. Children

AS2AI is intended for users aged 18 and older and is not directed to children. We do not knowingly design the current Android release to collect personal information from children.

9. International processing

AS2AI and its third-party service providers may process information on systems located outside your country or region. Where applicable, such processing is subject to the privacy and data-protection practices of those providers and applicable law.

10. Changes to this policy

We may update this Privacy Policy when AS2AI features, SDKs, service providers, or legal requirements change. The effective date at the top of this page will be updated when a revised policy is published.
