Privacy Policy
Effective Date: 2026-07-13
Data Controller / Developer: Hyosub Lee
Contact: contact.aminity@gmail.com
This Privacy Policy explains how Hyosub Lee handles information in connection with GoldMine(the "Service"), a Unity-based casual puzzle game for Android. The Service can be used without account registration. However, if a user uses Google Play Games Services sign-in or leaderboards, Google Play Games account and profile information may be used.
1. Information We Process
The Service does not ask users to enter information such as name, email address, or phone number. The Service does not provide its own account registration, forums, chat, or payment features. Google Play Games Services sign-in may be used for leaderboard functionality.
The Service may store the following information locally on the user's device:
| Category | Items | How It Is Processed |
|---|---|---|
| Game records | High score or highest coin record | Stored locally on the device using PlayerPrefs |
| Settings | Sound setting, vibration setting | Stored locally on the device using PlayerPrefs |
| Onboarding setting | Whether onboarding should be hidden next time | Stored locally on the device using PlayerPrefs |
| Gameplay state | Temporary gameplay state such as stage and coins | Processed locally while the game is running |
The Service uses Google Analytics for Firebase (Firebase Analytics) to improve game quality and balance. Firebase Analytics may process the following app usage information:
| Category | Items | Purpose |
|---|---|---|
| App and device information | App version, build information, platform, device and OS information, app-instance identifier, and similar technical information | Understanding app usage and improving service quality |
| Gameplay events | Game start, stage start/clear/failure, game over, restart, onboarding shown/closed, hint use, quake triggered, and similar events | Analyzing onboarding, difficulty, and game balance |
| Gameplay summary values | Stage, turn count, elapsed time, coin count, opened tile count, quake count, and similar summary values | Analyzing difficulty and gameplay flow by stage |
The Service does not send high-frequency tile-by-tile events individually. Such gameplay details are aggregated into stage result events where needed.
The Service uses the TikTok App Events SDK to measure app installs and advertising campaign performance. The following information may be transmitted to or processed by TikTok for Business:
| Category | Items | Purpose |
|---|---|---|
| Automatically logged app events | Install on first launch, app launch, and return on the day after first launch | Measuring installs and retention, advertising attribution, and campaign performance analysis |
| Game-start event | game_start, stage, app version, build information, platform, and a random gameplay session identifier | Measuring whether users start the game after acquisition and evaluating campaign performance |
| App, device, and network information | App identifier and version, device, OS and network-related technical information, IP address, advertising identifier, and similar information automatically processed by the SDK | Event delivery, deduplication, security, advertising measurement, and attribution |
The Service does not send Google Play Games player IDs, display names, email addresses, or phone numbers to the TikTok SDK. Thesession_id is a random value generated for a gameplay run and is not used as a Service account or Google Play Games account identifier.
The TikTok App Events SDK is initialized only if the user allows advertising measurement through the first-launch notice. Users may play the game without allowing it and may change their choice at any time in Settings. Withdrawing consent stops SDK transmission and deletes TikTok events waiting on the device, but information already transmitted before withdrawal may continue to be processed according to TikTok policies and applicable law.
The Service provides leaderboard functionality through Google Play Games Services. When a user signs in to Google Play Games or uses the leaderboard, the following information may be processed by Google or provided to the Service.
| Category | Items | Purpose |
|---|---|---|
| Google Play Games information | Player identifier, player profile or display name, Google Play Games sign-in status | Displaying leaderboards, identifying the player, providing Service functionality |
| Leaderboard information | High score or game score submitted to the leaderboard | Posting leaderboard scores, displaying rankings, preventing abnormal scores |
The Operator does not separately store Google Play Games leaderboard information on the Operator's own server. Information processed through Google Play Games Services may be handled according to Google's policies, the user's Google Play Games settings, and Google Account settings.
2. Ads, Payments, Leaderboards, and Other SDKs
The current Service does not display in-game ads or personalized ads and does not provide rewarded ads, in-app purchases, Operator-managed server-side saves, achievements, cloud saves, or Crashlytics. However, it includes the TikTok App Events SDK for app-install and advertising campaign measurement. The Service provides leaderboard functionality through Google Play Games Services.
The main third-party SDKs currently used by the Service are Firebase Analytics, the TikTok App Events SDK, and Google Play Games Services. Firebase Analytics is used for app usage statistics and game balance improvement, the TikTok App Events SDK for app-install and advertising campaign measurement, and Google Play Games Services for sign-in, leaderboard display, and score submission.
3. Purposes of Processing
The Service processes information for the following purposes:
- Saving and displaying game records
- Maintaining sound, vibration, and other user settings
- Remembering whether onboarding should be shown
- Providing gameplay and basic service functionality
- Displaying leaderboards and submitting scores through Google Play Games Services
- Analyzing stage difficulty, failure points, and restart flow
- Improving game quality and balance
- Measuring and attributing advertising campaign performance based on app installs, launches, returns, and game starts
The Service does not currently display in-game or personalized ads. It does process information through the TikTok App Events SDK for advertising measurement and attribution.
4. Retention
Game records and settings stored locally are retained on the user's device until the user deletes the app or clears the app data through device settings.
App usage information processed through Firebase Analytics may be retained according to Google/Firebase policies and the Firebase console settings. The Operator reviews such information only as aggregated or statistical data for analytics purposes.
Player information and leaderboard scores processed through Google Play Games Services may be retained or deleted according to Google's policies, the user's Google Play Games settings, and Google Account settings.
Information processed through the TikTok App Events SDK may be retained or deleted according to TikTok for Business policies, the applicable advertising account and Events Manager settings, and applicable law.
5. Sharing With Third Parties
The Operator does not sell personal information and does not arbitrarily disclose personal information to third parties through its own server.
Google LLC may process relevant information in connection with Firebase Analytics and Google Play Games Services. TikTok for Business operating entities and their affiliates and service providers may process relevant information in connection with the TikTok App Events SDK.
| Recipient | Purpose | Information That May Be Processed |
|---|---|---|

| Google LLC / Google Play Games Services | Google Play Games sign-in, leaderboard display, score submission, abnormal score prevention | Player identifier, player profile or display name, sign-in status, leaderboard score |
| TikTok for Business | App-install and launch measurement, advertising performance analysis and attribution, campaign optimization, and security | Automatically logged app events, game_start and its parameters, app, device and network information, IP address, advertising identifier, and similar information |
6. Service Providers and International Transfers
The Service may entrust relevant processing to Google LLC through Firebase Analytics and Google Play Games Services and may provide information to or engage TikTok for Business operating entities and their affiliates and service providers through the TikTok App Events SDK. These providers may store, access, or process information in facilities outside the user's country. Information is transmitted over the network when the app launches or a relevant event occurs.
| Service Provider | Processing Location | Purpose | Items |
|---|---|---|---|
| Google LLC / Firebase | Countries where Google operates its services | Providing Firebase Analytics and processing app usage statistics | App and device information, app-instance identifier, app usage events, gameplay summary values |
| Google LLC / Google Play Games Services | Countries where Google operates its services | Providing Google Play Games sign-in, leaderboards, and score submission processing | Player identifier, player profile or display name, sign-in status, leaderboard score |
| TikTok for Business operating entities, affiliates, and service providers | Singapore, the United States, and other countries where TikTok for Business, its affiliates, or service providers operate | Receiving app events, advertising measurement and attribution, campaign optimization, security, and service operations | Automatically logged app events, game_start and its parameters, app, device and network information, IP address, advertising identifier, and similar information |
For more information, please refer to Google's and Firebase's privacy and security documentation.
7. Children's Privacy
The Service is a casual game that can be used without the Service's own account registration. The Service does not provide features that directly ask children under 14 to enter personal information such as name or contact details. Availability and settings for Google Play Games Services may depend on Google and parental account settings. Data from or about Children, as defined by the TikTok Business Products (Data) Terms, must not be transmitted to TikTok. If the Service is primarily directed to Children, or if age gating or parental consent is required by applicable law, the Operator will implement the required measures before initializing the TikTok SDK or transmitting information.
8. Deletion
Locally stored information is deleted when the user deletes the app or clears the app data through device settings. If an in-app reset feature is provided, users may also delete certain game records through that feature.
Requests or inquiries related to information already transmitted through Firebase Analytics or the TikTok App Events SDK may be sent to the contact below. TikTok's privacy request procedures may apply to information held by TikTok. Management or deletion of leaderboard information processed through Google Play Games Services may be handled through methods provided by Google Play Games or Google Account settings.
- Privacy contact: contact.aminity@gmail.com
- Operator: Hyosub Lee
9. User Rights
Users may request access, correction, deletion, or suspension of processing of their personal information where applicable. Because the Service operates without accounts and stores records locally, users can delete locally stored information by deleting the app or clearing app data. TikTok advertising measurement can be withdrawn or enabled again in Settings, and declining or withdrawing it does not restrict gameplay.
Requests and privacy inquiries may be sent to:
- Privacy contact: contact.aminity@gmail.com
- Operator: Hyosub Lee
We will handle requests in accordance with applicable laws.
10. Security
The Service stores only necessary information locally and processes app analytics through Firebase Analytics using limited events and summary values. Only automatically logged app events and the game-start event are sent to TikTok, and Google Play Games user information is not sent to TikTok. The Operator minimizes events to what is necessary and does not individually transmit high-frequency detailed gameplay events.
11. Automatic Collection and Behavioral Data
The Service does not use web cookies.
The Firebase Analytics SDK may process app-instance identifiers, app and device information, and app usage events automatically or through event logging. The TikTok App Events SDK may process install, launch, return, and game_start events and may automatically process advertising identifiers, app, device and network information, and IP addresses for advertising measurement and attribution. The Google Play Games Services SDK may process information required to verify sign-in status, identify the player, display leaderboards, and submit scores. The Service does not currently display personalized in-game ads but uses the TikTok SDK for advertising measurement.
12. Changes to This Policy
We may update this Policy to reflect changes in laws, platform policies, Service features, or data practices. If material changes are made, we will provide notice through appropriate methods such as in-app notice, store listing, or a web page.
