Privacy Policy

This policy explains how the following iPhone games handle information: Jet Drift, Tokyo Konbini: Sort & Chill, HOSHI Claw Machine, Hong Kong: Lion Rock Rider (狮子山铁骑 / 獅子山鐵騎) and Robot Fighter: Rooftop Clash (机器人格斗：天台对决, in development; previously Rooftop Rumble) (each a "Game"). The Games are made by Junning Zeng, an independent developer ("we", "us").

Summary

• We do not require a separate game account. Optional Apple services, advertising and support messages process the information described below.
• We do not run our own gameplay servers or separate analytics service. Progress is saved locally. Jet Drift and Hong Kong: Lion Rock Rider also support optional Apple cloud saves and Game Center features. HOSHI Claw Machine 1.0 supports optional Game Center achievements and leaderboards, while its collection and coin balance stay on the device. Robot Fighter uses Apple-hosted online and cloud features described in its section below.
• The Games show ads from Google AdMob. Google may collect some device and usage information to deliver ads, as described below.
• The Games request non-personalized ads. HOSHI Claw Machine 1.0 does not enable its App Tracking Transparency permission request. Non-personalized ads can still process device, advertising and diagnostic data as described below.

Information stored on your device

Each Game saves your progress (for example levels, scores, stars, collections and coins), your settings and your ad-consent choice locally on your iPhone. Supported Apple cloud storage is described per game below; we do not operate a separate dedicated gameplay-server service. Deleting the app removes its local files, but Apple cloud saves or device backups may remain. Jet Drift also keeps local verification records in the iOS Keychain to prevent duplicate competitive rewards; Keychain records are subject to Apple’s storage lifecycle.

Tokyo Konbini: Sort & Chill: shop progress, inventory, settings, story choices and discovered endings stay on your device. In versions with Quick Sort, unfinished quick rounds are stored separately from the shop box. The game does not create a player account, provide its own cloud-transfer feature or upload these game saves to a gameplay server operated by us. Deleting its local data may remove this progress.

Robot Fighter: Rooftop Clash — online and cloud features

This game is in development. Its Apple-hosted online features process Game Center game-scoped player identifiers, Game Center display names, an assigned numeric game ID, robot selections, room membership and availability indicators. Public profiles, leaderboard standings, public verification keys and matchmaking restrictions may be visible to other players through Game Center or CloudKit public records. Individual settlement receipts and saved inventory are private cloud records. We do not receive your Apple Account password or verification codes.

Live matches use Game Center matchmaking and GKMatch. Match participants exchange inputs and game state, such as robot movement, attacks and match results. A participant acts as the host; we do not operate a dedicated match server. Signing into Game Center and iCloud is needed for the supported online and cloud features; local practice is also provided.

The game stores local caches and supported progress through Apple iCloud/CloudKit. Private cloud records are used for supported saved progress, inventory, individual match-settlement receipts and account-bound verification data; public/shared records support player discovery, friends, rankings, presence and moderation. Verification keys and signed records help detect duplicate or altered settlements. Changing Game Center accounts alone does not transfer ownership of an iCloud save.

Friend communication uses fixed phrases and emoji, rather than a free-text chat field. Current friend-message contents are encrypted by the game before cloud storage. Sender and recipient game IDs, key references and timestamps are associated metadata; encryption of message contents does not make public profiles or routing metadata private. In-match quick messages are sent to the match participants.

Advertising integration is being prepared for launch. Where enabled, Google AdMob processes the advertising data described in this policy, subject to applicable consent choices. Ads are intended for non-combat screens and optional rewarded offers. We do not send cloud-save contents, friend-message contents or Apple Account credentials to the ad SDK. Non-personalized requests do not mean that the SDK collects no data.

Deleting the app removes local files but may leave Apple-hosted cloud records and Keychain verification data. Apple account and iCloud storage controls apply to supported private data. For questions about shared profile records, data removal or a matchmaking restriction, contact rabbiesamurai@icloud.com with the game name and numeric game ID. Identity and integrity checks may be needed before a request can be handled; do not send passwords or verification codes.

Advertising (Google AdMob)

The Games display ads using the Google Mobile Ads SDK provided by Google LLC. Jet Drift shows native ads styled to match the game and offers an optional rewarded ad after a crash that you may choose to watch for one revival per run; Hong Kong: Lion Rock Rider shows a native ad card on the results screen and offers optional rewarded ads to revive after a crash in Daily or Random Challenge; some other Games also offer optional rewarded ads. The Games keep working normally when no ad is available. To serve ads, measure them and prevent fraud, Google may collect and process information such as:

• device information (for example device model, operating system version, language and app version);
• your IP address, which can indicate your approximate location;
• ad interaction data (for example which ads were shown or tapped);
• diagnostic and performance data related to ads.

Jet Drift, Tokyo Konbini: Sort & Chill and Hong Kong: Lion Rock Rider request non-personalized ads and do not ask for permission to access your device's advertising identifier (IDFA).

Tokyo Konbini: Sort & Chill: menus may show native ads, and eligible puzzle attempts may offer an optional rewarded video for rescue. Google may process device identifiers, advertising data, ad or app interactions, other usage data, approximate location inferred from network information, crash logs, performance data and other diagnostics for advertising, measurement, analytics, consent management and fraud prevention. Non-personalized requests and not requesting ATT permission do not mean that the SDK collects no data or that all partner data is unlinked to a device. Google's handling of advertising information follows the policies linked below.

Hong Kong: Lion Rock Rider: Google may associate advertising data, ad interactions and approximate location with app- or developer-bounded device identifiers for ad delivery, measurement and fraud prevention. Requesting non-personalized ads and not requesting ATT permission do not mean that the advertising SDK collects no data or that all of its data is unlinked to a device.

HOSHI Claw Machine (星之抓娃娃机) 1.0 requests non-personalized ads and does not enable its own App Tracking Transparency prompt. Google may still use app- or developer-bounded identifiers, approximate location inferred from IP addresses, ad interactions and diagnostics for ad delivery, measurement and fraud prevention. Not enabling ATT does not mean that the advertising SDK collects no data.

Google's handling of this information is described in Google's Privacy Policy (policies.google.com/privacy) and in "How Google uses information from sites or apps that use our services" (policies.google.com/technologies/partner-sites).

Consent (EEA, UK and Switzerland)

If you are in the European Economic Area, the United Kingdom or Switzerland, the Games ask for your consent with Google's consent form before ads are requested. You can review or change your choice at any time from Privacy options in the Game's settings.

Game Center and cloud saves (Jet Drift)

If you use Game Center, Jet Drift sends Daily Challenge distances, scores, achievement progress, season points and verification metadata to Apple to provide rankings and prevent duplicate rewards. The app uses Game Center’s game-scoped player identifier and nickname for these features; it does not receive your Apple ID password or email address. Leaderboard names and results may be visible to other players according to Apple’s Game Center privacy settings. We do not send Game Center identifiers or saved-game contents to the advertising SDK.

When the required Apple services are signed in and available, Jet Drift automatically synchronizes progress and supported preferences through Apple’s saved-game service and iCloud. This can restore progress after reinstalling or on another compatible device. If synchronization is unavailable, progress stays local. Apple handles these services under its Game Center privacy information and Privacy Policy. You can play without signing into Game Center.

Game Center and iCloud (Hong Kong: Lion Rock Rider)

If you use Game Center, Hong Kong: Lion Rock Rider sends Daily Challenge times, season and all-time points, the number of random challenges you have completed and achievement progress to Apple, together with verification metadata that helps reject altered scores, to provide rankings and achievements. The game uses Game Center’s game-scoped player identifier and nickname for these features; it does not receive your Apple ID password or email address. Leaderboard names and results may be visible to other players according to Apple’s Game Center privacy settings. We do not send Game Center identifiers or saved-game contents to the advertising SDK or to a gameplay server operated by us. You can play without signing into Game Center.

When you are signed into iCloud, the game can store a copy of your progress (routes cleared, medals, records, coins, unlocked items and supported settings) in Apple’s iCloud key-value storage, so that it can be restored after reinstalling or on another compatible device. When two devices have different progress, the game merges them on your device. If iCloud is unavailable or signed out, progress stays local. Apple handles this data under its Game Center privacy information and Privacy Policy; we cannot read it and do not operate a server that receives it.

Game Center (HOSHI Claw Machine)

If you choose to use Game Center, HOSHI Claw Machine sends achievement progress, unique collection counts, lifetime catches, virtual coins spent and seasonal catches with verification metadata to Apple. The game uses Game Center's game-scoped player identifier and may display Game Center nicknames and rankings. It does not receive your Apple ID password or email address. Leaderboard names and scores may be visible to other players according to Apple's Game Center privacy settings. We do not forward Game Center identifiers or local saved-game contents to the advertising SDK or to a gameplay server operated by us.

Version 1.0 keeps the collection, virtual coin balance and settings on your device; its custom iCloud progress synchronization is disabled. Signing into Game Center does not transfer or restore those local balances and collections. Local verification records in the iOS Keychain help detect modified saves and support reward recovery; those records follow Apple's storage lifecycle. The game remains playable without signing in or when Apple services are unavailable. Apple's services are governed by its Game Center privacy information and Privacy Policy.

To check UTC reward timing without relying only on the device clock, HOSHI Claw Machine may request an HTTPS response timestamp from an Apple-hosted page. The request contains a fresh random cache-busting value, not your coin balance, collection or Game Center identity. Network providers may process standard connection information such as IP addresses.

UTC timing (Hong Kong: Lion Rock Rider)

To check reward timing without relying only on the device clock, Hong Kong: Lion Rock Rider may read the HTTPS response timestamp from an Apple-hosted page. The request includes a fresh random cache-busting value, not your saved progress, coin balance or Game Center identity. When available, the current Game Center leaderboard period can also help check the UTC day. These requests use ordinary network connection information such as IP addresses; they are not requests to a gameplay server operated by us.

Sharing

Jet Drift can create a highlight image of your run, and Hong Kong: Lion Rock Rider can create a ride result card with your route, time and medal. HOSHI Claw Machine can create a card with the arcade scene, a virtual prize, collection or seasonal progress, a comment and a QR link to the app. Images are generated locally and are only shared when you tap Share and choose a destination in Apple's share sheet. We do not automatically upload or receive these images; the destination you select handles them under its own privacy practices.

In-app purchases

Some Games offer optional in-app purchases, such as removing ads. Purchases are processed by Apple through the App Store. We do not receive or store your payment details. The Game only checks with Apple on your device that a purchase is valid so it can unlock it, and keeps that record on your device.

Tokyo Konbini: Sort & Chill 1.0, HOSHI Claw Machine 1.0 and Hong Kong: Lion Rock Rider 1.0 do not offer in-app purchases. Lion Rock Rider’s garage items are unlocked with coins earned by playing, not with real money.

Children

The Games are not directed to children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information through a Game, please contact us and we will help.

Your choices

• Change your ad-consent choice in Privacy options in the Game's settings (where consent is required).
• Use Apple's Game Center settings to manage your public nickname and leaderboard visibility. You can turn off iCloud for the Game in iOS Settings → your name → iCloud. HOSHI Claw Machine 1.0 and Hong Kong: Lion Rock Rider can be played without signing into Game Center.
• Delete the app’s local files by deleting the Game. Cloud saves, Game Center records and Keychain verification records may remain under Apple’s service and storage rules.

If you contact support, we use your email address and message to respond; please do not send passwords or verification codes. Contact us for questions about access, correction or deletion. Apple manages Game Center and private cloud records, and Google manages advertising data under the linked policies. We do not maintain a separate online player-profile database.

Changes to this policy

If we change how the Games handle information, we will update this page and its effective date. Significant changes will also be noted in the App Store update notes.
