Effective September 24, 2026
This policy explains what information the mobile game Golden Bell Slots (the "Game") collects, how we use it, and the choices you have. The Game is made by DUCKGAMES ("we", "us"), Republic of Korea. Contact: developer@oduckgames.com.
What we collect
| Information | Why |
|---|---|
| Player ID. A random account ID created when you first play (Firebase Authentication). | To save your progress and find your account when you contact us. |
| Linked account. If you choose to link Google or Apple: the account identifier and the email address that Google or Apple share with us. Apple may give a private relay address. | So you can restore your progress on a new device. |
| Game progress. Coins, level, experience, piggy bank balance and similar game state. | To keep your progress safe on our server and restore it. |
| Jackpot records. A random device ID made by the Game, an automatically generated display name (for example "Player7F3A"), and the amount and time of jackpot wins. | To run the shared jackpot and show recent winners to other players. Only the display name and amount are shown. |
| Usage and device data. Events such as sessions, spins, feature use and purchases; device model, operating system, app version, language, approximate country derived from IP address, and app instance ID (Google Analytics for Firebase). | To understand how the Game is played, fix problems and improve balance. |
| Crash reports. When the Game crashes or hits an error: device model, operating system, app version, your Player ID and what the app was doing at that moment (Firebase Crashlytics). | To find and fix crashes and errors. |
| Advertising data. Your device's advertising ID, IP address, device information and ad interactions (Google AdMob). | To show ads, including rewarded ads you choose to watch, measure them and prevent fraud. Ads may be personalized unless you opt out (see below). |
| Purchase records. Confirmation of in-app purchases from Google Play or the App Store. We never receive your card or bank details. | To deliver what you bought and handle support requests. |
| Support messages. Your email address, what you write, and the app version, device model and Player ID the Game fills in. | To answer you. |
Game reminders (for example "your free coins are ready") are scheduled on your device. No personal information is sent to schedule them.
We do not ask for your real name, phone number, contacts, photos or precise location.
Who we share it with
We do not sell your personal information for money. We share it only with service providers that run the Game for us:
- Google (Firebase Authentication, Google Analytics for Firebase, Firebase Crashlytics, AdMob): Google Privacy Policy, how Google uses data from partner apps.
- Cloudflare hosts our game server that stores your progress and the jackpot: Cloudflare Privacy Policy.
- Apple and Google process payments and sign-in under their own policies.
We may also disclose information if the law requires it, or to protect the Game and its players from fraud or abuse.
These providers may process data outside your country, including in the United States. Where required, they use safeguards such as the European Commission's Standard Contractual Clauses.
Your choices
- Personalized ads. On Android, go to Settings › Google › Ads (or Settings › Privacy › Ads) and delete or reset your advertising ID. On iPhone, the Game does not track you across other companies' apps unless you allow it; you can change this in Settings › Privacy & Security › Tracking.
- Notifications. Turn off Alerts in the Game's settings or in your phone's settings.
- Account linking is optional. The Game works without it.
- Deletion. Delete your account and data in the game (☰ menu › About › Delete account), or email us. See Delete your data.
- Access and correction. Email us and we will send you a copy of your data or correct it.
- Ad consent (EU/UK). Change your choice at any time in ☰ menu › About › Ad privacy.
Depending on where you live (for example the EU, UK or California), you may have further rights, such as objecting to processing, restricting it, or complaining to your data protection authority. We will not treat you differently for using these rights.
Legal basis
If you are in the EU or UK: we process game progress, account and purchase data to provide the Game you asked for (contract); usage data to improve and secure the Game (legitimate interests); and personalized advertising data only with your consent where it is required.
How long we keep it
We keep your account and game progress while you play and until you ask us to delete it, or until the Game is shut down. Analytics data is kept for up to 14 months. Support emails are kept for up to 3 years so we can follow up on past issues. Records we must keep by law, such as for purchases, are kept for as long as the law requires.
Children
The Game is intended for adults (18+) and is not directed at children. We do not knowingly collect personal information from children. If you believe a child has given us information, email us and we will delete it.
Security
Data is sent over encrypted connections (HTTPS), and requests to our server are checked against your sign-in token. No method of storage or transmission is completely secure, but we work to protect your information.
Changes
If we change this policy, we will update the date at the top of this page. For significant changes we will also tell you in the Game.
