A random installation ID is used for leaderboard records.
Nickname, country, score, and phase may be visible to others.
Delete the cloud record and local app data from Settings.
// OVERVIEW
hopalt (“Developer,” “we,” or “us”) provides Bit 2048 Hard (“App”). This Privacy Policy describes how data is handled when you use the App.
The App does not require an email address, password, social login, or real-name account. It does create a pseudonymous leaderboard record using a randomly generated installation ID.
// DATA SUMMARY
| DATA | PURPOSE | LOCATION / PROCESSOR | PUBLIC? |
|---|---|---|---|
| Random installation ID | Identify and update your leaderboard record | Device and Google Firebase Firestore | No |
| Nickname, country code, best score, best phase, update time | Operate global and country leaderboards | Google Firebase Firestore | Nickname, country, score, and phase: Yes |
| Game progress, statistics, preferences, haptic setting | Save gameplay and settings | Your device | No |
| Locale or IP-derived country code | Choose a country code for rankings | Device locale; ipapi.co fallback | Country code only |
| Advertising and device data (Android) | Serve, secure, and measure banner ads | Kakao AdFit (Korea) / AppLovin MAX (other regions) | No |
// LEADERBOARD DATA
When the App initializes its leaderboard features, it stores the following in Firebase Firestore:
- Installation ID: a random UUID generated by the App and stored locally. It is not a hardware serial number or advertising ID.
- Nickname: generated automatically or entered by you. A custom nickname can currently be set once.
- Country code: detected from your device region, or through an IP-based lookup if the region is unavailable.
- Game record: best score, best phase, nickname status, and last update time.
- Country totals: aggregated player count, best score, and top phase by country.
// COUNTRY DETECTION
The App first uses the country/region in your device locale. If no country code is available, it may request a country code from ipapi.co. That request necessarily exposes your IP address and standard network request information to ipapi.co.
// FIREBASE AND ADVERTISING
Google Firebase Firestore stores and synchronizes leaderboard records. Google may process technical information necessary to provide, secure, and maintain the service.
On Android, the App shows banner ads using one of the following networks based on the device locale country code:
- Korea (KR): AdFit by Kakao Corp.
- Outside Korea: AppLovin MAX
Each ad SDK may collect advertising identifiers (GAID), device information, approximate location based on IP (AppLovin), and ad interaction data to serve and measure ads.
// LOCAL STORAGE AND RETENTION
The App uses local storage to keep the installation ID, game progress, scores and statistics, current phase, and settings. Local app data is generally removed when you clear the App’s storage or uninstall it, subject to your operating system and backup settings.
Leaderboard records are retained while the service operates or until you delete your data, unless longer retention is required for security, legal compliance, dispute resolution, or enforcement. Non-identifying country-level aggregates may remain after an individual record is deleted.
// YOUR CHOICES AND DATA DELETION
- Access: view your nickname, country, best score, best phase, and shortened installation ID in the App’s Settings or record screens.
- Deletion: open [ SETTINGS ] → DATA & PRIVACY → [ DELETE MY DATA ] and confirm.
- Ad choices: use your device privacy controls (Android: Settings → Google → Ads) and the AppLovin Privacy Portal where available.
- Contact: email us if the in-app deletion function is unavailable.
// CHILDREN, SECURITY, AND INTERNATIONAL PROCESSING
The App is not directed to children under 13, or under 14 in the Republic of Korea, and we do not knowingly request their personal information. If you believe a child has provided data, contact us so we can review and delete it.
We use reasonable safeguards appropriate to this service, but no network transmission or storage system is completely secure. Firebase, Kakao AdFit, AppLovin, and ipapi.co may process data on servers outside your country under their own policies and legal safeguards.
// POLICY UPDATES AND CONTACT
We may update this policy when the App, third-party services, or legal requirements change. The effective date above will be revised when changes are published.
v3.0.0 → v3.1.0 (2026-09-01): Replaced Google AdMob with Kakao AdFit (Korea) / AppLovin MAX (other regions) for Android banner ads.
