Gravicube — Privacy Policy

Effective date: 30 October 2026

This policy explains what information the Gravicube mobile game ("the app"), published by Biddigi ("we", "us"), collects, why, and the choices you have. Contact: biddigi25@gmail.com.

1. Summary

• You do not need an account to play. We do not ask for your name, email address, phone number, contacts, photos or precise location.
• Your game progress (levels, stars, coins, settings) is stored only on your device.
• The app shows ads through Google AdMob and measures app usage with Google Firebase. These services collect device identifiers and usage data as described below.

2. Information stored on your device

Game progress, daily-challenge history, coins and settings (sound, vibration) are saved in the app's local storage on your phone. We do not receive this data. Uninstalling the app or clearing its data deletes it.

3. Advertising (Google AdMob)

The app shows banner, interstitial (full-screen, between levels) and optional rewarded ads (you choose to watch one in exchange for a hint, an undo, an extra attempt or bonus coins). Ads are provided by Google AdMob. To deliver, measure and limit ads and to prevent fraud, Google may collect:

• Device identifiers such as the Android Advertising ID and App Set ID;
• IP address, from which an approximate (city-level) location may be inferred;
• Device and app information (model, operating system, language, app version);
• Ad interactions (impressions, clicks, rewards earned).

Depending on your choices and your region, ads may be personalised. Google's use of this data is governed by Google's Privacy Policy (policies.google.com/privacy) and "How Google uses information from sites or apps that use our services" (policies.google.com/technologies/partner-sites).

4. Consent and your choices

• Where required by law (for example in the EEA, the UK and Switzerland, and in some US states), the app asks for your consent through Google's User Messaging Platform before personalised ads are shown. You can change your choice at any time in Settings → Privacy choices inside the app.
• You can reset your Advertising ID or delete it (opt out of personalised ads) in your phone's settings: Settings → Google → Ads (or Settings → Privacy → Ads, depending on your device).
• Rewarded ads are always optional.

5. Analytics and configuration (Google Firebase)

We use Google Analytics for Firebase to understand how the game is played (for example which levels are completed or abandoned, session length, retention, ad impressions and estimated ad revenue) and Firebase Remote Config to adjust game and ad settings without an app update. Firebase collects an app-instance identifier, device and app information, approximate location derived from IP address, and in-app events. This data is used in aggregate to improve the game and to measure our advertising campaigns. We do not use it to identify you personally. See firebase.google.com/support/privacy.

6. Advertising our app

We may advertise Gravicube through Google Ads. To measure which ads lead to installs, Google may link app installs and in-app events (such as level completion) with ad clicks using the identifiers described above.

7. How information is shared

We do not sell your personal information. Information is shared only with the service providers named above (Google AdMob and Google Firebase) for the purposes described, or when required by law.

8. Data retention and deletion

On-device data stays until you uninstall the app or clear its data. Google retains analytics and advertising data according to its own retention settings (Firebase Analytics event data is retained for up to 14 months). Because we do not hold accounts, we cannot link data to you by name; to ask a question or make a request, email us at the address above and include the request type.

9. Security

Data sent by the Google SDKs is encrypted in transit (HTTPS).

10. Children

Gravicube is intended for a general audience aged 13 and over and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided information, contact us and we will help remove it.

11. Your rights

Depending on where you live (for example under the GDPR, the UK GDPR, India's Digital Personal Data Protection Act 2023, or US state privacy laws), you may have rights to access, correct, delete or object to processing of your personal data. Contact us to exercise them.

12. Changes

We may update this policy. The effective date above shows the latest version. Significant changes will be noted in the app's store listing.
