Privacy Policy
Firework Master (불꽃 장인 키우기) · Last updated October 9, 2026 · 한국어
This game has no sign-up or login and never asks for your name, email address or phone number. Your game progress is stored only on your device. However, for rewarded ads (Google AdMob) and purchase verification (RevenueCat), the information listed below may be sent to those service providers.
1. What we process and why
| Category | Information | Purpose |
|---|---|---|
| Ads (Google AdMob) |
Advertising identifier (iOS IDFA / Android advertising ID — only if you allow tracking), ad impressions and views, device information (model, operating system, language), IP address, ad errors and performance data | Serving rewarded ads, personalized ads where you have allowed them, fraud prevention, measuring ad performance |
| In-app purchases (RevenueCat) |
A random anonymous user ID created by the app, purchase history (product, time, store receipt), app and device information (app version, operating system, country) | Verifying purchases, delivering what you bought, “Restore Purchases” |
| Stored only on your device | Game progress such as stage, gold, upgrades, Pals and check-in records, plus sound and language settings | So your progress continues when you close and reopen the app. It is not sent to our servers |
Payments themselves are handled by the Apple App Store or Google Play. Payment details such as card numbers, bank account information and billing addresses go directly to Apple or Google and are never passed to us.
This app does not request access to your contacts, photos, location, microphone or camera, and it does not use any other analytics tools.
2. Your choices about tracking and personalized ads
- iPhone and iPad: the first time you open the app, it asks whether to allow “App Tracking Transparency”. You can enjoy the game exactly the same either way; if you decline, no advertising identifier is used and you will see non-personalized ads. You can change this any time in Settings → Privacy & Security → Tracking.
- Android: you can reset or delete your advertising ID in Settings → Privacy (or Google) → Ads.
- European Economic Area, United Kingdom and Switzerland: before any ad is requested, a consent form from Google’s consent management platform asks whether you agree to the use of your data for ads. You can review or change your choice at any time under Settings → Help → Ad privacy settings, which appears in these regions.
- Ads play only when you choose to watch one to earn a reward. No ads appear on their own while you play.
3. Sharing, service providers and international transfers
While you use the app, the information in section 1 is sent over the internet to, and stored by, the companies below.
| Recipient | Country | Data | Their policy |
|---|---|---|---|
| Google LLC (AdMob) | United States | Ad information in section 1 | Google Privacy Policy, How Google uses information from partner apps |
| RevenueCat, Inc. | United States | In-app purchase information in section 1 | RevenueCat Privacy Policy |
Because these providers are in the United States, your information may be transferred outside your country, including from the EEA, the UK and Switzerland. The providers describe the safeguards they rely on for such transfers in their own policies. Their retention periods and deletion methods also follow those policies.
4. How long we keep it
- Game progress on your device: until you delete it. Deleting the app deletes it too. You can also erase it yourself in the game under Settings → Help → “Erase save and start over”.
- Purchase history (RevenueCat): kept to verify purchases and restore them. To have it deleted, please contact us using the details below.
- Ad information (Google): kept for the period set by Google’s policies.
5. Children
This app is not directed at children and we do not knowingly collect children’s personal information. Because the game has paid items, parents can restrict purchases in their device settings (for iPhone: Screen Time → Content & Privacy Restrictions → In-App Purchases; for Android: Google Play parental controls and purchase authentication).
6. Your rights
You can change tracking and advertising-ID choices at any time as described in section 2, and you can erase game data on your device yourself. If you are in the EEA, the UK or Switzerland, you also have the right to request access to, correction of, deletion of or restriction of the personal data processed about you, to object to its processing, to receive it in a portable form, to withdraw consent (for example, for personalized ads) at any time, and to lodge a complaint with your local data protection authority. To request access or deletion of information held by our service providers, such as purchase history, contact us below. We have no account records, so including the time and product name of your purchase will help us handle your request faster.
Where we rely on your consent (personalized ads), withdrawing it does not affect processing carried out before you withdrew it. For purchases, we process the information needed to carry out the purchase you made, and we rely on our legitimate interests to prevent fraud and measure ad performance.
7. When this policy changes
If anything changes, we will update this page and the date above. For significant changes, such as processing more kinds of information, we will also tell you in the app.
