This policy applies to the Android game Underleaf (林间荡跃).
The game stores scores, distance, unlocks, Leaf Marks, tutorial progress, language and audio preferences in Unity PlayerPrefs on your device. We do not operate player accounts, cloud saves, or a player-data server. We do not send your local game progress to our own server or to the advertising SDK.
Scores, Leaf Marks and other gameplay progress remain local and are not cloud-saved. For optional paid cosmetics, the game also caches verified Google Play purchase receipts, product entitlements and a hashed transaction marker on your device. Clearing app data removes this local cache, but eligible non-consumable purchases can be restored from Google Play when you use the same Google Play account. When the game can check Google Play again, refunded or revoked purchases are removed from the local entitlement.
The game uses Google Mobile Ads (AdMob) to show a banner ad at the bottom of the home screen, optional rewarded ads for one revive per run and an optional doubled Leaf Mark reward at the result screen. An ordinary interstitial may appear after several completed runs at a natural break. The banner is hidden during gameplay, pause, revive and results. Watching a rewarded ad is optional. The game grants its in-game reward only when the SDK confirms that the ad earned a reward.
Google Mobile Ads may automatically collect and share IP address (which can indicate approximate location), app launches and ad interactions, performance and diagnostic data, Android advertising ID, app set ID and other device or account identifiers, for ad delivery and personalization, measurement, analytics, frequency control, fraud prevention and security. The data processed varies with your region, consent choices, device settings and Google policies. We do not receive your name, contacts, messages or precise location from ads.
Where required, Google User Messaging Platform (UMP) asks for your consent or privacy choice before ads are requested. If a privacy options entry point is required, you can reopen it from the game's home screen under “Ad privacy settings”. Declining personalized ads does not necessarily remove all ads; Google may still serve non-personalized or limited ads and process data needed for security and fraud prevention.
The game uses Google Analytics for Firebase to understand installs and campaign attribution and to measure aggregate game use. Firebase may process app-instance and device identifiers, app version and language, first opens and sessions, campaign or Play install-referrer information, approximate location inferred from IP address, device and operating-system information, diagnostics, and in-game events such as starting or ending a run, distance, score, mode, power-up type, tutorial completion and whether an optional rewarded ad completed. We use this information to compare promotion channels, improve difficulty and retention, diagnose failures and understand advertising performance. We do not send player names, email addresses, free-form text, contacts, precise location or the local save file to Analytics.
Firebase is initialized before UMP so Google Consent Mode can apply the privacy choice to analytics storage, advertising storage, ad user data and ad personalization where required. We do not set an Analytics user ID or build a player account profile.
To understand the optional cosmetic shop, we send Firebase Analytics events for shop and item views, purchase attempts, cancellations or failures, restore attempts, and verified cosmetic unlocks. These events may include the product ID, cosmetic category or theme, outcome or failure reason, and the price and currency shown at checkout. We do not send raw purchase receipts, purchase tokens, payment-card details or your Google account email in our custom Analytics events. Where Google Play and Firebase are linked, Google may also process purchase events under its own policies.
Our Google Analytics account has Google products and services data sharing enabled. Google may use Analytics data to improve its products and services, including Google Ads tools; Google says this setting does not use the data for Google's own ad personalization or targeting.
The game's networked services are Google Mobile Ads (AdMob), Google User Messaging Platform (UMP), Google Analytics for Firebase, and Google Play Billing through Unity In-App Purchasing for optional, one-time cosmetic purchases. Google Play processes payment and retains the authoritative purchase record; the game receives and validates signed purchase information to grant or restore cosmetics. We do not receive payment-card numbers or bank-account details and do not operate a player-account, cloud-save or developer payment server. We do not integrate Unity Analytics or Unity Ads. INTERNET and ACCESS_NETWORK_STATE support advertising, consent messages, analytics and purchase services. Google Play Billing also uses the BILLING permission. Google SDKs may declare AD_ID and Android Privacy Sandbox permissions. The game does not request camera, microphone, contacts, SMS, call logs or precise location permissions. Google states that Mobile Ads and Firebase data is encrypted in transit.
For details, see Google Mobile Ads data disclosure, Firebase privacy and security and Google Privacy Policy.
Local progress remains until you clear the app's data or uninstall the game. Because we have no server copy, we cannot remotely restore or delete that progress. Google retains advertising and Analytics data according to the Firebase project's retention settings and Google policies. Clearing app data or uninstalling removes local identifiers; a later installation may create a new app-instance identifier. You may reopen the in-game privacy options when available, manage ad preferences in Google's My Ad Center, or reset or delete the Android advertising ID in device settings.
Deleting the app does not by itself cancel or erase a Google Play purchase. You can manage your Google Play orders and refunds through Google Play. Restoring cosmetics requires the same Google Play account and a valid, non-refunded purchase; ordinary local gameplay progress cannot be restored this way.
The game is intended for a general audience and is not specifically directed to children. We do not knowingly collect personal information from children under 13 or a higher local minimum age. Google and its advertising partners may process data outside your country or region subject to their policies and safeguards.

本政策适用于 Underleaf Studio 提供的 Android 游戏《林间荡跃》（Underleaf）。
游戏使用 Unity PlayerPrefs 在设备本地保存分数、距离、解锁内容、叶印、新手引导进度，以及语言和声音设置。我们不运营玩家账号、云存档或玩家数据服务器，不会把本地游戏进度发送到自建服务器或广告 SDK。
分数、叶印等游玩进度仍只保存在本机，不提供云存档。对于自选付费外观，游戏还会在设备本地缓存已验证的 Google Play 购买收据、商品权益及经过哈希处理的交易去重标记。清除应用数据会删除这些本地缓存，但使用同一 Google Play 账号时，可从 Google Play 恢复仍有效的非消耗型购买。游戏再次联网核对后，会移除已退款或撤销订单对应的本地权益。
游戏使用 Google Mobile Ads（AdMob）在主页底部展示横幅广告，并提供自选激励广告：每局一次复活机会，以及结算时自选双倍叶印。每完成几局后，可能在自然间隙展示不发奖励的普通插屏广告。进入游戏、暂停、复活和结算页面后会隐藏横幅广告。玩家可以不观看激励广告；只有广告 SDK 确认奖励后，游戏才会发放相应游戏内奖励。
Google Mobile Ads 可能自动收集或共享 IP 地址及推断的大致位置、应用启动与广告互动、性能与诊断数据、Android 广告 ID、应用集 ID，以及其他设备或账号标识符，用于广告投放与个性化、效果衡量、分析、频次控制、防欺诈和安全。具体处理取决于地区、同意选择、设备设置与 Google 政策。我们不会通过广告获得玩家姓名、通讯录、消息或精确位置。
在适用地区，Google User Messaging Platform（UMP）会在请求广告前征求同意或隐私选择。需要提供隐私选项入口时，玩家可在游戏首页点击“广告隐私设置”重新打开。拒绝个性化广告不一定移除所有广告；Google 仍可能提供非个性化或受限广告，并处理安全和防欺诈所需数据。
游戏使用 Google Analytics for Firebase 分析安装来源、推广归因和汇总游玩情况。Firebase 可能处理应用实例及设备标识符、应用版本和语言、首次打开与会话、广告系列或 Google Play 安装引荐信息、由 IP 地址推断的大致位置、设备和系统信息、诊断信息，以及开局、结算、距离、得分、模式、道具类型、教程完成、可选激励广告是否完成等游戏内事件。我们利用这些信息比较推广渠道、改善难度和留存、排查故障并了解广告效果。游戏不会向 Analytics 发送玩家姓名、邮箱、自由输入文本、通讯录、精确位置或本地存档。
Firebase 会先于 UMP 初始化，以便 Google Consent Mode 在适用地区把隐私选择应用到分析存储、广告存储、广告用户数据和广告个性化。游戏不会设置 Analytics 用户 ID，也不会建立玩家账号档案。
为了解自选外观商店的使用情况，我们会向 Firebase Analytics 发送商店和商品浏览、发起购买、取消或失败、尝试恢复，以及经验证后解锁外观等事件。事件可能包含商品 ID、外观类别或主题、结果或失败原因，以及结账时展示的价格和币种。我们不会在自定义 Analytics 事件中发送原始购买收据、购买令牌、支付卡信息或 Google 账号邮箱。Google Play 与 Firebase 关联后，Google 也可能依据其政策处理购买事件。
我们的 Google Analytics 账号已开启“Google 产品和服务”数据共享。Google 可能使用 Analytics 数据改进其产品和服务（包括 Google Ads 工具）；Google 表示此设置不会将这些数据用于 Google 自身的广告个性化或定向投放。
游戏使用的联网服务包括 Google Mobile Ads（AdMob）、Google User Messaging Platform（UMP）、Google Analytics for Firebase，以及通过 Unity In-App Purchasing 接入的 Google Play Billing，用于自选的一次性外观购买。Google Play 处理付款并保存正式购买记录；游戏接收和验证已签名的购买信息，以发放或恢复外观权益。我们不获取支付卡号或银行账户资料，也不运营玩家账号、云存档或开发者自建支付服务器。游戏未接入 Unity Analytics 或 Unity Ads。INTERNET 和 ACCESS_NETWORK_STATE 用于广告、同意消息、分析及购买服务；Google Play Billing 还使用 BILLING 权限。Google SDK 可能声明 AD_ID 和 Android Privacy Sandbox 相关权限。游戏不请求相机、麦克风、通讯录、短信、通话记录或精确位置权限。Google 表示 Mobile Ads 与 Firebase 数据在传输过程中会加密。
详情见 Google Mobile Ads 数据披露说明、Firebase 隐私与安全说明和 Google 隐私权政策。
本地游戏进度会保留到玩家清除应用数据或卸载游戏。我们没有服务器副本，无法远程恢复或删除进度。Google 会依据 Firebase 项目的保留设置及其政策保存广告和 Analytics 数据。清除应用数据或卸载会移除本地标识符；重新安装后可能生成新的应用实例标识符。玩家可在需要时重新打开游戏内隐私选项，在“我的广告中心”管理广告偏好，或在 Android 设置中重置、删除广告 ID。
卸载游戏本身不会取消或删除 Google Play 购买记录。你可以通过 Google Play 管理订单和退款。恢复外观需要同一 Google Play 账号和仍有效、未退款的订单；普通本地游玩进度无法通过此方式恢复。
游戏面向一般用户，并非专门面向儿童。我们不会故意收集 13 岁以下儿童或当地更高最低年龄以下用户的个人信息。Google 及其广告合作方可能依其政策和保障措施在玩家所在国家或地区之外处理数据。
