Effective date: 2026-09-27 · Last updated: 2026-09-27 (versionCode 4: Play Games activation and automatic SDK data)
Summary
KronDx: Neon Brick Breaker (the "app") is developed by MiniAppFactory ("we", "us").
The game itself runs offline: your progress, earned coins, skins and boosters are saved
on your own device, and we do not operate any server of our own. The app uses Google services, each governed by
Google's Privacy Policy
in addition to this policy:
Google Play Billing connects at startup and resume to load prices and recover unfinished purchases. Buying a coin pack is optional.
Google Play Games Services is enabled from versionCode 4. It initializes at launch for automatic authentication and service analytics/diagnostics. Existing profiles may sign in automatically under your Google settings; signed-in players' accumulated scores are then synchronized. Gameplay remains available without signing in.
The app shows no ads, contains no advertising, analytics or crash-reporting SDK of our own,
has no chat or user-generated content, and never requires an account to play.
Data stored on your device
The app stores the following information locally, in Android's app-private storage
(SharedPreferences). This information is not sent to us:
In-game coin balance (earned coins and coins credited from purchased packs)
Level progress, stars earned and per-level best scores (up to 500 levels), and the
resulting total score
Owned and equipped paddle skins, owned support boosters
Daily reward streak and the last date a daily reward was claimed
Sound on/off preference
A record of each completed coin-pack purchase (Google Play purchase token, product id,
coins credited, time) — kept so that the same purchase can never be credited twice,
and so that an interrupted purchase can be completed after a restart
The highest score submitted per Play Games profile and leaderboard, keyed by a one-way hash of the profile identifier
Android Auto Backup may back up and restore wallet, progress and other app data under your device and Google account settings. Backup timing and availability are not guaranteed; we cannot access or restore your backup. Play Games leaderboards are not a cloud save or a wallet backup.
Google Play Billing (coin packs)
The shop offers five one-time coin packs (1,000 / 2,200 / 3,600 / 5,200 / 7,000 coins).
Buying one is entirely optional; every coin can also be earned by playing. Purchases are
processed by Google Play, not by us:
Your payment method, billing address and full purchase history are handled by Google
Play under Google's terms and privacy policy. We never see your card or payment details.
The app receives from Google Play only what it needs to deliver the coins: the product id,
a purchase token, an order id, the purchase state (paid or pending) and the price text shown
in the shop. Prices are displayed in your local currency as provided by Google Play.
Coins are credited on your device and the purchase is then marked as consumed with Google
Play. If a purchase is pending (for example a cash payment at a store), coins are credited
once Google Play reports it as paid.
Refunds and receipts are managed through Google Play. Purchased coins are a digital in-game
item; they have no cash value and cannot be transferred or exchanged.
We do not send purchase data to any server of our own. Purchase records stay on your device
as described above.
Google Play Games Services (leaderboard)
Enabled from versionCode 4. The online leaderboard uses your total score, the sum of your best score in each level. A lower replay does not reduce that total. The game also keeps your local total and remains playable without a Play Games profile or successful sign-in.
Play Games initializes when the app starts. Existing profiles may sign in automatically according to your Google settings, without pressing the game's Sign In button. Automatic profile-creation prompts are suppressed for devices without an existing Play Games profile; you can start that process from Sign In.
After authentication, the app reads your Play Games player ID and display name (gamer tag). It automatically submits a higher accumulated total after sign-in and as your score improves. Opening the online leaderboard is not required for synchronization.
Google handles profile identity, leaderboard storage and visibility. The Google leaderboard can show your gamer tag, avatar and score according to your profile settings. The game does not request your legal name, Google e-mail address, contacts or friends list.
We do not operate an account database. The app stores a hash of the player/leaderboard identifier and the last confirmed score locally to avoid duplicate submissions. Play Games does not back up or restore your coin wallet, unlocks or level progress in this app.
You can change sign-in behavior or sign out through your device's Google settings → All services → Play Games → Sign in account, or the Play Store's Play Games profile settings. See Google's sign-in and privacy controls. Restart the game after changing the account. Signing out stops authenticated score synchronization; it does not disable the app's Google SDK diagnostics.
Permissions
The app declares the INTERNET and ACCESS_NETWORK_STATE permissions, used only by Google Play Billing and Google
Play Games Services as described above; the game logic never opens network connections of its own.
The Google Play Billing library also declares Google Play's billing permission
(com.android.vending.BILLING). The app requests no location, storage, camera, microphone,
contacts or other sensitive permission.
Diagnostics
We do not add a separate developer analytics or crash-reporting service. Google Play Billing starts at launch/resume and sends service operation and diagnostic information to Google. Play Games also initializes at launch and automatically collects analytics and diagnostics for service stability and improvements. These SDK activities do not wait for a purchase or the game's Sign In button, and the app has no switch to disable them. Google's Play Games data disclosure and Privacy Policy describe its processing. Google also operates Android vitals under its platform settings.
Technical diagnostics can include randomly generated SDK client/session identifiers, app and SDK versions, device model/manufacturer and OS build information, memory, locale, network type, operation results and event timings. The inspected Billing integration does not request advertising IDs, Android ID, IMEI or GPS coordinates.
Data we share and data we sell
We do not sell any data. We do not share data with third parties other than the Google services
named above, which provide payments and configured leaderboards, including service operations described above.
Children
KronDx: Neon Brick Breaker is a general-audience arcade game intended for players aged 13 and over and
is not directed at children. It contains no chat and no user-generated content. Real-money coin packs
and the online leaderboard are optional and go through Google Play, which applies its own age and
parental-control settings (including purchase authentication). We do not knowingly collect personal
information from children.
Your choices / deleting data
Local game data (coins, progress, skins, boosters, purchase records, settings):
go to Android Settings → Apps → KronDx: Neon Brick Breaker → Storage & cache → Clear storage,
or uninstall the app. Note that clearing storage also removes coins credited from purchased packs;
Google Play keeps the purchase receipt, but consumed coin packs cannot be restored.
Play Games data: manage sign-in separately from deletion. Use Google's game-data deletion instructions to delete KronDx's Play Games data or your profile. Deletion from Google does not erase the game's local score; if you keep the local data and sign in again, the app can submit that score again. To prevent that, remain signed out or also clear local game data.
For any other request, e-mail us at the address below.
Clearing local app storage does not delete Android backup copies or records retained by Google. Manage backups through your device or Google backup settings and use Google privacy controls for Google service data. We cannot erase Google payment receipts or guarantee deletion of Google diagnostic records on your behalf.
Changes
Version history: versionCode 3 kept Play Games disabled; versionCode 4 enables the behavior described above.
If this policy changes, the new version will be published at this same URL with a new "Last updated"
date. Changes to data practices will be described in this policy and in the app where required.
