一、概述
1. Overview
CubeMoment（以下简称"本应用"）是一款 3×3 魔方的 3D 模拟益智应用，提供跟手转层、视角操控、随机打乱、自动计时、步数统计、还原判定、新手教学与可选的云端排行榜等功能。
你在本应用内的使用数据（设置偏好、本地游玩记录等）仅保存在你自己的设备中，本应用不会上传至任何服务器或共享给第三方；如你在设备上开启了系统级应用备份（Android 自动备份），该数据可能由操作系统备份至你的 Google 账号（详见"数据如何存储"章节）。为维持应用免费运营，应用内可能展示第三方广告服务（Google AdMob）提供的横幅与插屏广告；除本政策"第三方服务"与"排行榜与登录"章节披露的情形外，本应用不收集或传输你的个人数据。
本应用提供可选的云端排行榜功能：你可自愿登录 Google Play 账号，将"最快还原 / 最少步数"成绩上传至云端参与排名。该功能完全可选，不登录也可使用全部核心玩法。
CubeMoment ("the App") is a 3D simulator and puzzle app for the 3x3 Rubik's Cube, featuring smooth layer turns, camera control, one-tap scramble, an auto timer, a step counter, solve detection, a built-in tutorial, and an optional cloud leaderboard.
Your usage data in the App (preferences, local play records, etc.) is stored only on your own device; the App never uploads it to any server or shares it with third parties. If you have enabled OS-level app backup (Android Auto Backup), that data may be backed up by the operating system to your Google account (see "How Your Data Is Stored"). To keep the App free, it may display banner and interstitial ads served by a third party (Google AdMob); apart from the disclosures in the "Third-Party Services" and "Leaderboard & Sign-In" sections, the App does not collect or transmit your personal data.
The App includes an optional cloud leaderboard: you may voluntarily sign in with a Google Play account to upload your fastest solve / fewest moves for global ranking. This is entirely optional — every core feature works without signing in.
二、我们收集哪些信息
2. What Information We Collect
我们不收集你的个人数据。具体包括：
- 不收集你的姓名、联系方式、位置等个人信息；未登录时，你的游玩数据不离开你的设备；
- 应用内无统计 SDK、无追踪服务；广告由 Google AdMob 提供，其 SDK 可能收集设备广告标识符等常规信息（见"第三方服务"章节）；
- 核心玩法无需账号、无云同步；云端排行榜为可选项——如自愿登录 Google Play 账号，将读取你的昵称并上传成绩（见"排行榜与登录"章节）；
- 应用仅在加载广告或使用排行榜功能时需要联网，不会向任何服务器发送你未主动上传的数据。
We do not collect your personal data. Specifically:
- No name, contact details, or location are collected; until you sign in, your play data never leaves your device;
- No analytics SDKs or tracking services; ads are served by Google AdMob, whose SDK may collect routine information such as the advertising ID (see "Third-Party Services");
- Every core feature works without an account or cloud sync; the cloud leaderboard is optional — if you voluntarily sign in with Google Play, your nickname is read and your scores are uploaded (see "Leaderboard & Sign-In");
- The app only needs internet access to load ads or use the leaderboard; it never sends data you did not actively upload.
三、数据如何存储
3. How Your Data Is Stored
本应用产生的数据（如触感反馈等偏好设置，以及本地游玩记录）仅保存在你设备的本地存储中。卸载应用或清除应用数据将删除这些内容；若开启了系统级应用备份（Android 自动备份，默认开启），卸载前的数据可能由操作系统保留在你的 Google 云端硬盘中，可在系统备份设置中删除，请按需操作。
若你登录云端排行榜，你的 Google 昵称与已上传的成绩将存储于 Google Play Games 服务器（由 Google 运营，见"排行榜与登录"章节）；退出登录可停止后续同步，已上传成绩的处理遵循 Google 隐私政策。
All data the App produces (preferences such as haptics, as well as local play records) is stored only in the local storage on your device. Uninstalling the app or clearing its data will delete this content; if OS-level app backup (Android Auto Backup, on by default) is enabled, pre-uninstall data may be retained by the operating system in your Google Drive and can be removed from the system backup settings — please act as needed.
If you sign in to the cloud leaderboard, your Google nickname and uploaded scores are stored on Google Play Games servers (operated by Google; see "Leaderboard & Sign-In"). Signing out stops further sync; uploaded data is handled per Google's privacy policy.
四、权限使用说明
4. Permissions
- 网络权限（INTERNET）：用于加载应用内的第三方广告内容；若你登录云端排行榜，也用于上报 / 拉取成绩。除你主动上传的成绩外，不传输其他数据。
- 其他权限：本应用不申请存储、位置、通讯录、相机、麦克风等敏感权限；应用内触感反馈使用系统内置反馈能力，无需额外权限。
- Internet (INTERNET): used to load third-party ad content in the App and, if you sign in to the cloud leaderboard, to submit and fetch scores. Apart from scores you actively upload, no other data is transmitted.
- Other permissions: none of the sensitive permissions (storage, location, contacts, camera, microphone, etc.) are requested. In-app haptics use the system's built-in feedback capability and require no extra permission.
五、第三方服务
5. Third-Party Services
本应用使用 Google AdMob 广告服务（由 Google LLC 提供）来展示横幅广告与插屏广告，以维持应用免费运营。插屏广告仅在两局之间展示（即你点击「再来一局」开始新局之前），并设有最短展示间隔，不会在你游玩过程中无预期弹出。为展示广告，AdMob SDK 可能收集并使用以下常规信息：设备广告标识符（Advertising ID）、设备型号与系统版本、网络状态、IP 地址等，用于广告投放、频次控制与效果统计。
你可以随时在系统设置中"重置广告 ID"或关闭"个性化广告"，这不会影响本应用的其他功能。上述信息的处理遵循 Google 隐私政策（policies.google.com/privacy）。除广告服务外，本应用仅在启用排行榜时接入 Google Play Games 服务（见下一段）。应用商店分发平台（如 Google Play）可能出于平台运营目的收集的常规信息，与其各自的隐私政策有关。
若你使用云端排行榜，本应用将通过 Google Play Games 服务（Google LLC）读取你的 Google 昵称并上传 / 拉取游戏成绩（完成用时 / 步数），用于全球排名展示。该服务仅在登录后活跃，你可以随时在应用内退出登录；相关数据的处理遵循 Google 隐私政策。
The App uses the Google AdMob advertising service (provided by Google LLC) to display banner and interstitial ads and keep the App free. The interstitial appears only between solves (i.e., before a new solve starts when you tap "Play again") with a minimum display interval; it never pops up unexpectedly during play. To serve ads, the AdMob SDK may collect and use routine information such as the advertising ID, device model and OS version, network state, and IP address, for ad delivery, frequency capping, and performance measurement.
You can reset your advertising ID or disable personalized ads at any time in your device settings; this does not affect any other functionality of the App. Such data is handled according to Google's privacy policy (policies.google.com/privacy). Apart from the ad service, the App integrates Google Play Games only when the leaderboard is in use (next paragraph). Routine information collected by app stores (e.g., Google Play) for platform operation is governed by their own privacy policies.
If you use the cloud leaderboard, the App works with the Google Play Games service (Google LLC) to read your Google nickname and submit/fetch game scores (solve time / move count) for world-wide ranking. This service is active only while signed in; you can sign out at any time in the App, and data is handled per Google's privacy policy.
六、排行榜与登录（可选）
6. Leaderboard & Sign-In (Optional)
本应用的云端排行榜功能完全可选：不登录 Google 账号时，你仍可使用全部核心玩法，App 保持纯本地运行，不产生任何云端数据。
登录后：本应用将读取你的 Google 昵称用于排行榜展示；仅在打破个人纪录（更快时间 / 更少步数）时自动上传成绩（首次登录时会一次性补传此前在本地已达成的历史最佳）；你可以随时查看全球 Top 10 与自己的名次。
退出登录：应用内可随时"退出登录"，此后本应用不会再次自动登录，也不会继续上传成绩。已上传至云端的历史成绩由 Google Play Games 系统管理，如需删除请按 Google 提供的账户数据管理方式操作。
13 岁以下儿童不启用排行榜账号登录；若监护人允许未成年人使用，请监督其仅在您同意的前提下登录。
The cloud leaderboard is entirely optional: without signing in to a Google account, all core features keep working and the App remains fully local with no cloud data at all.
When signed in: your Google nickname is read for display; scores are uploaded automatically only when you beat your personal best (a faster time or fewer moves) — on first sign-in, any historical bests already achieved locally are uploaded once; you can view the global top 10 and your own rank at any time.
Signing out: you can sign out at any time in the App; afterwards the App will not sign in again automatically or upload further scores. Historical scores already uploaded are managed by the Google Play Games system; to delete them, follow Google's account data management procedures.
Leaderboard sign-in is not used by children under 13; if a guardian permits minors to use the App, please ensure they sign in only with the guardian's consent.
七、儿童隐私
7. Children's Privacy
本应用面向 13 岁及以上的普通用户，不针对 13 岁以下儿童提供服务。由于本应用不收集任何个人数据，我们不存在针对儿童的数据收集行为。
This app is intended for general users aged 13 and above and is not directed at children under 13. Since the App does not collect any personal data, there is no data collection targeting children.
八、政策变更
8. Changes to This Policy
如本隐私政策发生变更，我们将在本页面更新内容并标注新的更新日期。若未来本应用新增任何数据收集功能，我们会提前通过应用内说明或应用商店更新日志等方式告知。
If this policy changes, we will update this page and revise the date above. If the app ever adds any data collection feature, we will inform you in advance via in-app notices or store release notes.
