IRONBRICK ("the app") is built and operated by JK IT Works. This page describes what the app receives, what it is used for, and when it is deleted. You can start playing immediately as a guest, and in that case no account information is collected.
1. What we collect
| Data | When | Used for |
|---|---|---|
| Advertising ID (AAID / IDFA) | When you watch a rewarded ad | Serving ads, limiting repeats, blocking invalid clicks |
| Email address | Only when you link an account | Verifying it is you, continuing on another device, leaderboard entries |
| Device identifier | When the app starts | Syncing your save, preventing duplicate rewards |
If you only play as a guest, no email is collected. We ask you to link an account only when you want your score on the leaderboard.
2. What we do not collect
- Name, phone number, address, date of birth
- Contacts, photos, files, location
- Passwords — sign-in is by email verification only, so no password is ever created or stored
3. Sharing and processors
We do not sell personal data. The services below handle data on our behalf so features can work.
| Recipient | Data | Purpose |
|---|---|---|
| Google (AdMob) | Advertising ID | Serving and measuring rewarded ads |
| Google (Firebase Authentication) | Email address | Sign-in |
| Our own server (AWS, Seoul region) | Email, device identifier, game records | Save sync and leaderboards |
Google operates servers outside your country, including in the United States. While you watch ads or sign in, that data is transferred abroad. If you would rather it were not, you can play as a guest without watching ads.
4. Retention and deletion
- When you delete your account, we erase the data on our server immediately. There is no separate retention period.
- Uninstalling the app alone does not delete your account; server records remain. To remove everything, please request account deletion as described below.
- The app does not store your advertising ID. Google handles it under its own policies.
5. Your rights
- You may request access to, correction of, or deletion of your data at any time.
- Account deletion: email joonjkit@gmail.com and we will verify and erase it.
- Resetting your advertising ID: on Android, Settings › Privacy › Ads; on iOS, Settings › Privacy & Security › Tracking.
6. Children
We do not knowingly collect personal data from children under 14. If we learn that we have, we delete it immediately.
7. Changes to this policy
If this policy changes, we will post the new version here with its effective date. Material changes, such as collecting additional data, will also be announced inside the app.
