1. Overview
This policy explains the categories of information processed, the purposes, retention periods and your rights when the Nyangbu team (the "operator") provides the mobile application Nyangbu (the "app"). The operator complies with the privacy laws applicable where you are located, including the Korean Personal Information Protection Act and the EU GDPR.
2. Information we do not collect
- Real name, national ID, phone number, contacts — we do not require real-name registration.
- Photos, camera, microphone, precise location — the app does not use camera, gallery, microphone or location (GPS) permissions. See section 4 for approximate location.
3. Information we process and why
| Data | Purpose | Processed by |
|---|---|---|
| Anonymous device identifier (deviceId) — a random ID created per device. It is not linked to a real name or account; your gold (g) balance and mining/swap records are tied to this ID | Managing your gold balance and mining records, recognising a returning device | Operator server |
| App interactions (launch, mining, check-in, missions, rewarded-ad use, swap requests and other usage events), diagnostics (app version, error and performance data), app instance ID, device info (model, OS, language), approximate region (IP-based) | Usage analytics, improving the app, install measurement such as first_open | Google Firebase Analytics |
| Device IDs such as the advertising ID, device info, approximate location estimated from the IP address, ad interactions | Serving, personalising and measuring ads; managing ad consent | Google AdMob · Google UMP |
| Gold (g) ledger (balance, credits and debits) and swap request details — the item being swapped, the request time, and the contact to receive the gift card (the phone number or email you enter when requesting a swap) | Sending gift cards, checking delivery status, reviewing for abuse | Operator server |
Collected / shared data summary (Google Play Data safety categories)
- Approximate location — the app does not ask for location itself. Our ads partner (Google AdMob) estimates it from the IP address and collects/processes it for advertising.
- Device or other IDs (anonymous device identifier, advertising ID, app instance ID) — collected for app functionality (managing your gold balance), analytics and advertising; the advertising and analytics IDs are shared with Google.
- Personal info — the contact to receive a gift card (phone number or email) is collected only when you request a swap, for the purpose of delivering the item.
- App interactions and diagnostics — collected for analytics and advertising and shared with Google.
All data is transmitted over an encrypted connection (HTTPS).
Ads and consent
The app shows Google AdMob ads (banner, interstitial, rewarded and more). Rewarded ads play only when you choose to watch one, for example to speed up mining. For users in the EU, the UK and similar regions, the app requests consent through Google UMP (a consent management platform). In those regions, Firebase Analytics usage collection follows that choice and happens only when you consent to storing/accessing device information and measuring content performance. Elsewhere, usage analytics is on by default. Where applicable, you can change your consent at any time from "Ad privacy settings" in the settings screen, and you can reset or delete your advertising ID or limit personalised ads in your device settings. Even without consent, non-personalised ads may be shown, and approximate (IP-based) location may still be used for ad delivery and fraud prevention. See Google's partner sites policy for details.
Gold (g) and swap information
In-game gold (g) is an in-app point used only to swap for items. It has no cash value, cannot be exchanged for cash or transferred to another user, and cannot be withdrawn. Gold is not a prepaid electronic payment instrument. When you request a gift card swap you enter a contact (phone number or email) to receive it; this is used only to deliver the item and check delivery status. After delivery it is kept for the period required for dispute handling and by applicable law, then deleted.
4. Retention
- Gold (g) ledger and anonymous device identifier: kept until you stop using the app or request deletion; may be deleted after a period of inactivity.
- Contact details in a swap request: kept after delivery for the period required for dispute handling and by e-commerce and other applicable laws, then deleted.
- Data processed by Google (Firebase Analytics, AdMob): governed by each service's retention policy (Firebase Analytics event data up to 14 months).
5. Sharing, processors and international transfers
The operator does not sell your information. The analytics and advertising data in section 3 is shared with Google (Firebase Analytics, AdMob, UMP) for usage analytics and ad processing. The contact details in a gift-card swap may be shared with delivery agents and item suppliers acting as processors, only to the extent needed to deliver the item. We do not share with any other third parties. These services may operate outside your country (for example in the United States).
6. Children's privacy
The app is not directed to children under 13 (or the age set by the laws where you live) and does not knowingly collect their personal information. If we learn that a child's data has been collected, we delete it without delay.
7. Your rights and deletion requests
You can change your ad consent from "Ad privacy settings" (where applicable) in the settings screen, or reset/delete your advertising ID in your device settings. To access, correct or delete your gold ledger, anonymous device identifier or swap contact details, email us below. We will verify your request and act without undue delay.
8. Changes to this policy
If this policy changes, we will post it on this page with the new effective date.
