一、概述
1. Overview
「唯一空格」（以下简称"本应用"）是一款本地数字滑块拼图益智游戏，提供 3×3、4×4、5×5 三档难度。本地玩法无需账号、无需联网；你也可以自愿登录 Google Play Games，参与可选的世界排行榜比拼（详见"第三方服务"章节）。
你的游戏数据（各档最佳成绩、音效与震动等设置）默认仅保存在你自己的设备中，本应用不会上传或共享这些数据。唯一的例外是：当你主动登录 Google Play Games 后，为参与云端排行榜，应用会将你在各难度的最佳成绩（最短用时与最少步数）上传至 Google 排行榜服务器。为维持应用免费运营，应用内展示由第三方广告服务（Google AdMob）提供的广告；除本政策"第三方服务"章节披露的情形外，本应用不收集或传输你的个人数据。
OneGap ("the App") is a local sliding-puzzle game offering 3×3, 4×4, and 5×5 difficulty levels. Local play requires no account and no internet connection; you may optionally sign in to Google Play Games to take part in cloud leaderboards (see "Third-Party Services").
Your game data (best scores for each difficulty, sound & vibration settings, etc.) is by default stored only on your own device; the App never uploads or shares it. The only exception: once you voluntarily sign in to Google Play Games, your best results per difficulty (fastest time and fewest moves) are uploaded to Google's leaderboard servers so you can take part in cloud rankings. To keep the App free, it displays ads served by a third party (Google AdMob); apart from the disclosures in the "Third-Party Services" section, the App does not collect or transmit your personal data.

二、我们收集哪些信息
2. What Information We Collect
本应用自身不收集你的个人数据。具体包括：
- 本应用自身没有账户体系，不要求也不收集你的姓名、联系方式、位置、通讯录等个人信息；
- 最佳成绩、设置项等本地游戏数据不离开你的设备；本应用无统计、分析或追踪 SDK，不向任何服务器上报行为日志；
- 可选的云端排行榜：仅当你主动登录 Google Play Games 后，应用才会把你在各难度的最佳成绩（最短用时与最少步数）上传到 Google 排行榜服务器，并以你的 Play 昵称展示名次。账号由 Google 提供与验证，本应用无法读取你的密码；你可在"排行榜"弹层中随时退出登录以停止后续上传；
- 应用仅在展示广告或（登录后）同步排行榜时需要联网，联网过程中不会向任何服务器发送你的其他游戏数据。
The App itself does not collect your personal data. Specifically:
- The App has no account system of its own and does not require or collect personal information such as your name, contact details, location, or contacts;
- Local game data such as best scores and settings never leaves your device; the App has no analytics, measurement, or tracking SDK and sends no behavior logs to any server;
- Optional cloud leaderboards: only when you voluntarily sign in to Google Play Games does the App upload your best results per difficulty (fastest time and fewest moves) to Google's leaderboard servers and display your rank under your Play nickname. The account is provided and verified by Google — the App can never read your password. You may sign out anytime in the "Leaderboards" panel to stop further uploads;
- The App needs network access only to display ads or (after sign-in) to sync leaderboards, and it never sends any other game data to any server while doing so.
三、数据如何存储
3. How Your Data Is Stored
你在本应用内产生的数据（各档难度下的最佳成绩、音效与震动开关、已同意的协议版本等）仅保存在你设备的本地存储中（DataStore Preferences）。卸载应用或清除应用数据将永久删除这些内容，本应用不提供云端备份或恢复，请谨慎操作。
All data you create in the app (best scores per difficulty, sound & vibration preferences, the accepted agreement version, etc.) is stored only in the local storage of your device (DataStore Preferences). Uninstalling the app or clearing its data will permanently delete this content, and the App provides no cloud backup or recovery — please operate with care.
四、权限使用说明
4. Permissions
- 网络权限（INTERNET）：用于加载与展示应用内的第三方广告，以及在登录后同步 Google Play 排行榜，不会传输你的其他游戏数据。
- 广告标识符（AD_ID）：供广告 SDK 读取设备广告标识符，用于广告投放、频次控制与欺诈防范（详见"第三方服务"章节）。你可在系统设置中关闭"个性化广告"或重置广告标识符。
- 震动权限（VIBRATE）：用于游戏内的操作反馈（滑动方块、通关时的震动提示）。你可随时在系统设置或应用内设置中关闭。
- 存储、位置、相机、麦克风、通讯录等敏感权限：本应用一律不申请。
- Internet (INTERNET): used to load and display third-party ads and, after sign-in, to sync Google Play leaderboards. It never transmits your other game data.
- Advertising ID (AD_ID): lets the ad SDK read the device advertising ID for ad delivery, frequency capping, and fraud prevention (see "Third-Party Services"). You can disable personalized ads or reset your advertising ID anytime in system settings.
- Vibrate (VIBRATE): used for in-game haptic feedback (moving tiles, victory buzzes). You can turn it off anytime in system or in-app settings.
- Sensitive permissions (storage, location, camera, microphone, contacts, etc.): none are requested.
五、第三方服务
5. Third-Party Services
本应用使用以下第三方服务：
- Google AdMob 广告服务（由 Google LLC 提供）：用于展示广告以维持应用免费运营，包括游戏页底部的横幅广告（Banner），以及每局结束后偶尔展示的插屏广告（为避免频繁打扰，展示频率会受到合理控制）。为投放、频控、效果统计与防欺诈，AdMob SDK 可能收集并使用设备广告标识符（Advertising ID）、设备型号与系统版本、网络状态、IP 地址等常规信息。
- Google Play Games 排行榜服务（由 Google LLC 提供）：提供可选的世界排行榜。当你主动登录 Google Play Games 时，应用会在你通关后上传该难度的最佳成绩（最短用时与最少步数），并在排行榜上展示你的 Play 昵称与名次；此过程由 Google 提供服务，账号验证、昵称与成绩等数据依 Google 的隐私政策处理。本应用无法读取你的 Play Games 密码，也不会因此获得你在 Google 的其他个人信息。你可在"排行榜"弹层中随时退出登录以停止后续上传；已上传数据的管理遵循 Google 政策。
你可以在系统设置中随时"重置广告 ID"或关闭"个性化广告"，这不会影响本应用的游戏功能。上述信息的处理遵循 Google 隐私政策（policies.google.com/privacy）。应用商店分发平台（如 Google Play）出于平台运营目的收集的常规信息，受其各自隐私政策约束。
The App uses the following third-party services:
- Google AdMob advertising service (provided by Google LLC): displays ads to keep the App free, including a banner ad at the bottom of the game screen and occasional interstitials after a round (reasonably rate-limited to avoid being intrusive). To serve ads, measure performance, cap frequency, and prevent fraud, the AdMob SDK may collect and use routine information such as the advertising ID, device model and OS version, network state, and IP address.
- Google Play Games leaderboard service (provided by Google LLC): offers optional worldwide leaderboards. When you voluntarily sign in to Google Play Games, the App uploads your best result (fastest time and fewest moves) for a difficulty after each round and shows your Play nickname and rank on the leaderboard. This service is operated by Google, and account verification, nickname, and scores are handled under Google's privacy policy. The App can never read your Play Games password and gains no other personal information about you from Google. You may sign out anytime in the "Leaderboards" panel to stop further uploads; management of already-uploaded data follows Google's policies.
You can reset your advertising ID or disable personalized ads anytime in system settings; this does not affect the App's gameplay features. Such data is handled according to Google's privacy policy (policies.google.com/privacy). Routine information collected by app stores (e.g., Google Play) for platform operation is governed by their own privacy policies.
六、年龄限制与儿童隐私
