This policy describes how Duck Match Jam (the “game”, “we”, “us”) handles information when you play the game, use its online features, or contact its support team. Our privacy contact is 17737131949@163.com.

1. Information we process

• Game identity and progress: randomly generated guest/player and installation identifiers, session credentials, save versions and timestamps, levels, scores, best winning streaks, virtual currency, items, lives and relevant game preferences. These support saving progress, restoring an available save and preventing conflicting updates.
• Profile and leaderboard information: your in-game nickname, selected game avatar, scores and ranking. Leaderboards are global, and other players can see the profile and score information shown there. Do not put contact details or sensitive information in your nickname.
• Usage and game analytics: app launches and sessions, level starts and results, attempt identifiers, play durations, app/SDK versions, and advertising requests, impressions, rewards and revenue information. Our publisher analytics service uses these records to understand game performance, progression and advertising results.
• Network, device and advertising information: online services receive your IP address and request information. Advertising and measurement providers may process device model and operating system, language, app interactions, diagnostics, advertising or app identifiers, ad network/campaign/creative information, and approximate location inferred from IP address. What is processed depends on the provider, enabled features, your device settings and privacy choices.
• Support messages: the email address and information you choose to send when contacting us. Please do not send passwords, login tokens, payment-card details or government identification documents.

The game's own cloud-save and leaderboard features do not require access to your contacts, camera, microphone or precise GPS location. Third-party advertising data is described separately above and in the providers' policies below.

2. Why information is used

We use information to run the game, save progress, display global rankings, deliver and measure advertisements, improve game balance and reliability, detect abuse, answer support requests and meet applicable legal obligations. Where applicable law requires consent for a particular activity, that activity must be supported by the relevant consent choice; this policy itself is not a consent request.

3. Service providers and sharing

Game data is processed by our game backend and hosting provider, Tencent Cloud. Gameplay and advertising events are sent to the publisher's BI reporting service. Advertising mediation may involve the providers listed below; the list identifies integrations and does not mean that every provider serves an ad to every player.

• AppLovin MAX / AppLovin — advertising mediation, delivery, measurement and fraud prevention.
• Google AdMob and User Messaging Platform — advertising and applicable privacy-choice messages.
• Unity Ads / ironSource — advertising services.
• Pangle — advertising services; its page provides region-specific policies.
• Mintegral — advertising services.
• Adjust — installation attribution and advertising/engagement measurement when you enable ad measurement.

These providers may process information under their own privacy policies and use other service providers or advertising partners. We may also disclose information when required by law or necessary to address fraud, security incidents or legal claims. Your full cloud-save contents and session credentials are not displayed on public leaderboards.

4. Your privacy choices

• In the game's Settings → Privacy menu, the ad-measurement switch controls the Adjust integration. It is off by default. Turning it off stops future Adjust measurement through this integration; it does not erase data already processed.
• The Privacy Options entry is shown when the advertising consent service requires it. Use it to review available advertising choices. You can also use your device's advertising-ID and ad-privacy controls.
• The Adjust switch does not turn off cloud saves, leaderboards or the publisher's separate gameplay/advertising BI reports.
• Depending on your location, you may have rights to access, correct, delete or obtain a copy of your information, restrict or object to processing, withdraw consent, or complain to a data-protection authority. Contact us using the email below to exercise applicable rights. Advertising providers also offer their own privacy request channels.

5. Storage, retention and security

The game cloud service is hosted in the United States. Analytics and advertising providers may process information in other countries described in their policies. Transfers and any required safeguards must follow applicable data-protection requirements.

Game profiles and cloud saves remain on the live service until they are deleted; uninstalling the app or clearing local data does not automatically delete server records. Database backups rotate on a 30-day schedule. After a deletion from the live game service, an older backup copy may remain until that rotation completes. Service logs, support correspondence and analytics records are retained for the relevant operational, support, security or legal purpose; records held by independent providers are subject to their retention policies.

We use HTTPS for the game service and restrict administrative access. The service stores refresh-credential hashes rather than raw refresh credentials. No system can guarantee absolute security. Keep your device and email account secure.

6. Data deletion and privacy requests

To request deletion of your Duck Match Jam guest profile and associated cloud save, leaderboard profile and scores, email 17737131949@163.com with the subject “Duck Match Jam data deletion request”. You can use this email link outside the game or open this page from the game's Privacy menu.

Tell us which information you want deleted and, if available, your player identifier, in-game nickname and approximate last-play date. If you do not know your identifier, tell us that; support will help identify the relevant records and may ask for proportionate verification before acting. Do not send a password, session token or private key. These are manually handled support requests, not an automatic deletion button.

Verified requests cover the associated live game records we control, subject to any applicable legal retention requirement. We will explain any such exception and relevant retention when handling your request. Deletion can make your progress unrecoverable. Please stop using the guest profile after requesting deletion, as continuing to play may generate new data. For analytics or advertising records held by independent providers, contact us for help or use the provider's privacy channel.

7. Children and families

Parents or guardians who believe a child has provided information that should not have been collected can contact us. We will review the request and address the affected information as required by applicable law. Please do not include a child's sensitive personal information in a nickname or support message.

8. Changes and contact

We will update this page when the game's data practices change and revise the effective date. If Google sign-in or other account features are introduced, their data practices will be explained before use, with any additional notice or consent required by law. Privacy questions: 17737131949@163.com.

隐私政策

本政策说明 Duck Match Jam（“本游戏”“我们”）在提供游戏、在线功能和客服支持时如何处理信息。隐私联系邮箱：17737131949@163.com。

一、处理哪些信息

• 游戏身份与进度：随机生成的游客、玩家和安装标识，会话凭据、存档版本和时间，以及关卡、分数、最高连胜、虚拟货币、道具、体力和相关游戏偏好，用于保存进度、恢复可用存档和避免更新冲突。
• 个人资料与榜单：游戏昵称、所选游戏头像、分数和名次。排行榜为全球榜，其他玩家可以看到榜单展示的资料和成绩。请勿在昵称中填写联系方式或敏感信息。
• 游戏统计：启动与会话、关卡开始和结果、单局标识、游玩时长、应用及 SDK 版本，以及广告请求、展示、奖励和收入。发行 BI 服务使用这些记录分析游戏表现、进度和广告效果。
• 网络、设备与广告信息：在线服务会接收 IP 地址和请求信息；广告及测量服务商可能处理设备型号、系统、语言、应用交互、诊断信息、广告或应用标识、广告网络与活动/素材信息，以及根据 IP 推测的大致位置。实际处理取决于服务商、功能、设备设置和隐私选择。
• 客服信息：您来信使用的邮箱及主动提供的内容。请勿发送密码、登录令牌、银行卡信息或身份证件。

游戏自身的云存档和排行榜不需要读取通讯录、相机、麦克风或精确 GPS 位置。第三方广告数据处理见上文及下方服务商政策。

二、信息用途

我们用信息运行游戏、保存进度、展示全球排名、提供及衡量广告、改进关卡平衡和稳定性、防范滥用、处理客服请求及履行适用法律义务。某项处理依法需要同意时，应通过相应同意选项获得授权；本政策本身不代替同意操作。

三、服务商与共享

游戏数据由本游戏后端及腾讯云托管服务处理；游戏和广告事件上报至发行方 BI 服务。已集成的广告服务包括 AppLovin MAX、Google AdMob/UMP、Unity Ads、ironSource、Pangle 和 Mintegral；开启广告效果测量时使用 Adjust。集成清单不代表每位玩家每次都会收到所有服务商的广告。各服务商的政策链接在本页英文部分列出，Pangle 提供按地区区分的政策。

这些服务商可能依据各自政策处理数据，并使用其他服务商或广告合作方。依法需要，或处理欺诈、安全事件及法律争议时，我们也可能披露必要信息。完整云存档和会话凭据不会在公开排行榜中展示。

四、您的选择

• “设置 → 隐私”中的广告效果测量开关控制 Adjust，默认关闭；关闭后停止本集成后续的 Adjust 测量，不会自动删除此前已处理的数据。
• 广告同意服务要求时显示“隐私选项”，您可在其中检查可用的广告选择，也可使用系统广告标识与广告隐私设置。
• Adjust 开关不会关闭云存档、排行榜或独立的发行 BI 游戏/广告统计。
• 根据所在地法律，您可能享有访问、更正、删除、获取副本、限制或反对处理、撤回同意和向监管机构投诉等权利。可通过本页邮箱提出适用请求；广告服务商也提供独立的隐私请求渠道。

五、保存地点、期限与安全

游戏云服务部署在美国。统计和广告服务商可能在其政策所述的其他国家处理信息；相关传输及所需保护措施应遵守适用法律要求。

游戏档案与存档在在线服务中保留，直至被删除；卸载游戏或清除本机数据不会自动删除服务器记录。数据库备份按 30 天轮换，因此在线记录删除后，旧备份中可能继续存在副本，直至轮换完成。服务日志、客服通信和统计记录按运营、客服、安全或法律用途保留；独立服务商的记录遵循各自保存政策。

游戏服务使用 HTTPS 并限制管理访问权限，服务器保存刷新凭据的哈希而非原始刷新凭据。任何系统都无法保证绝对安全，请保护好设备和邮箱。

六、删除数据与隐私请求

如需删除 Duck Match Jam 游客档案及其云存档、榜单资料和成绩，请向 17737131949@163.com 发送主题为“Duck Match Jam 数据删除申请”的邮件。您可以在游戏外直接使用此邮箱，也可以从游戏“隐私”入口打开本页。

请说明希望删除的内容，并在知道的情况下提供玩家标识、游戏昵称和大致最近游玩日期。不知道玩家标识也可联系；客服会协助定位记录，并可能在处理前进行适当的身份核验。请勿提供密码、会话令牌或私钥。本入口提交的是人工客服请求，不是自动删除按钮。

核验后的请求覆盖我们控制的相关在线游戏记录；若有适用的法定保留要求，会在处理时说明例外及期限。删除可能使进度无法恢复，申请后请停止使用该游客档案，继续游玩可能产生新数据。独立服务商持有的统计或广告记录，可以联系本客服协助或通过对应服务商的隐私渠道申请。

七、儿童与家庭

如果家长或监护人认为儿童提供了不应被收集的信息，可通过本页邮箱联系。我们会核查并按适用法律处理相关信息。请勿在昵称或客服消息中填写儿童敏感个人信息。

八、更新与联系

当实际数据处理发生变化时，我们会更新本页及生效日期。未来如启用 Google 登录或其他账号功能，会在使用前说明其数据处理，并提供依法需要的额外告知或同意。隐私联系：17737131949@163.com。
