Privacy Policy

QUANTUM IX UNITED INC.  |  Effective date: 10 October 2026 · Last updated: 10 October 2026

This Privacy Policy explains what information is used when you play the mobile game Dungeon Escape Expedition (the "Service"), why, who receives it and the choices you have. QUANTUM IX UNITED INC. ("we", "us") is responsible for the Service. The Service is free to play, shows ads and offers optional in-app purchases. You do not need to sign up to play, and we do not ask for your name, e-mail address or phone number.

1. Information used by the Service

2. Why we use it

3. Advertising and your choices

EEA, UK and Switzerland — before personalised ads are shown, the Service asks for your consent through Google's consent form. You can change your choice at any time with the Ad privacy settings button in the game's Settings. This button appears only in regions where the law requires it.

United States — in states with privacy laws (for example California), using ad data for personalised ads can count as "selling" or "sharing" personal information. You can opt out at any time with the device controls below: choose "Ask App Not to Track" on iPhone, or delete your advertising ID on Android. After that you will see only non-personalised ads. Where Google's consent tool offers it in your state, the Ad privacy settings button in the game's Settings also lets you opt out.

iPhone and iPad — the Service asks for permission through Apple's App Tracking Transparency before any tracking. If you choose "Ask App Not to Track", your advertising identifier is not used, no ad-consent form is shown and only non-personalised ads are requested. You can change this in iOS Settings → Privacy & Security → Tracking.

Android — you can delete or reset your advertising ID in your device settings (usually Settings → Google → Ads or Settings → Privacy → Ads). Non-personalised ads are still based on context such as the app and your approximate location, and Google still uses some data to measure ads and prevent fraud. Learn more in How Google uses information from sites or apps that use its services.

4. Who receives information

We do not sell your personal information for money and we do not share it with data brokers. Information goes only to these providers, each for the purpose listed:

RecipientPurposeInformationLocation
Google LLC (AdMob)Show and measure ads, prevent ad fraudAdvertising ID, IP address, approximate location, device and app information, ad interactionsUnited States and other countries where Google operates
Google LLC (Google Play) / Apple Inc. (App Store)Process payments and refundsPurchase and transaction information (handled under their own privacy policies)United States and other countries

We may also disclose information if the law requires it, or to protect the rights and safety of our users or of us.

5. International transfers

The providers above may process information outside your country, including in the United States. Where required (for example for users in the EEA and UK), transfers rely on safeguards such as standard contractual clauses used by those providers.

6. How long we keep it

We keep no personal information ourselves. Game data stays on your device until you delete the app or its data. Ad and purchase providers keep information under their own policies.

7. Children

The Service is not directed to children under 13 (or the higher age required in your country). We do not knowingly collect personal information from children. If you believe a child has given us information, e-mail us and we will help.

8. Your rights

Depending on where you live (for example in Korea, the EEA, the UK or California) you may have rights to access, correct, delete or restrict the use of your information, to object to personalised ads, and to withdraw consent. We will not treat you differently for using these rights.

You also have the right to complain to a data protection authority — for example your local authority in the EEA, the UK Information Commissioner's Office, or the Personal Information Protection Commission in Korea.

9. Security

Your game data stays on your device. No service is completely secure, but we work to protect your information.

10. Changes

We may update this policy, for example when we add new features. We will change the date above and, for important changes, tell you in the Service.
