感谢您使用「中性浮力模拟」（以下简称“本应用”）。本政策说明本应用如何处理与您有关的信息。
一、适用范围与个人信息处理者
本政策适用于本应用。
个人信息处理者：张坤鹏
联系邮箱：eagle.zhang2026@qq.com
二、本应用处理的信息
1. 设备本地数据
本应用会在您的设备本地保存训练记录、最高分、语言偏好、图鉴与解锁进度、设置、协议确认状态及其他维持本地功能所需的数据。
本应用不会主动将上述训练及设置数据上传至开发者运营的服务器，开发者无法远程访问。上述数据是否被纳入 Apple 设备备份或 iCloud 备份，取决于您的设备、系统及备份设置；开发者无法访问您的系统备份。
2. 应用内购买与恢复购买
如当前版本提供付费解锁，购买和恢复购买由 Apple App Store 或相应应用商店处理。本应用可能在设备上处理应用商店返回的商品标识、购买状态、交易结果或有效权益信息，以完成解锁和恢复购买。
开发者不会获得您的银行卡号、Apple 账户密码或完整支付信息。当前版本不将购买凭证上传至开发者运营的服务器；如未来增加服务器验证，我们会在启用前更新本政策并依法履行告知义务。
3. 意见反馈
当您主动使用“意见反馈”功能时，本应用会调用设备上的邮件应用。只有在您确认发送后，开发者才会收到您主动提供的邮箱地址、反馈内容、附件，以及您选择保留在邮件中的应用信息。
这些信息仅用于回复、排查问题、处理售后和改进产品，不用于广告、用户画像或与反馈无关的目的。
4. 保存成绩图片
当您主动点击“保存到相册”时，本应用仅为向系统照片图库添加您生成的成绩图片，请求相应的照片添加权限。本应用不会主动浏览、分析或上传照片图库中的其他内容。
5. 系统分享和外部应用
当您主动使用分享功能时，本应用会调用系统分享面板。只有在您选择目标应用并确认分享后，相应图片或文字才会交由您选择的第三方应用处理。
第三方应用将按照其自身隐私政策处理相关内容。调用系统分享面板本身不表示本应用通过开发者服务器上传您的数据。
三、账号、广告、分析及其他权限
1. 本应用当前不提供账号注册或登录。
2. 本应用当前不含第三方广告，不使用第三方行为分析、广告追踪或跨应用追踪工具。
3. 本应用当前不申请定位、通讯录、相机或麦克风权限。
4. 本应用中的音频、视频、二维码生成和训练记录存储，当前均用于设备本地功能。
5. 如未来增加账号、云同步、广告、统计分析、推送通知或其他会改变个人信息处理方式的功能，我们将在启用前更新本政策，并依法履行告知或取得同意。
四、信息共享、转移与公开披露
我们不会出售或出租您的个人信息。
除下列情形外，我们不会主动向第三方提供您的个人信息：
1. 根据您的主动操作，通过系统分享面板向您选择的应用发送图片或文字；
2. 您主动通过邮件应用发送反馈；
3. 由 Apple 或其他应用商店处理购买、退款和恢复购买；
4. 根据法律法规、司法程序或有权机关依法提出的要求；
5. 经您单独同意或法律另有规定的其他情形。
如因合并、分立、重组、资产转让或类似交易确需转移个人信息，我们将依法告知接收方信息，并要求接收方继续履行个人信息保护义务。
五、信息保存期限
1. 设备本地数据会保留至您使用应用内删除功能删除相应内容（如该功能已提供），或卸载本应用。开发者无法代您远程删除设备本地数据。
其中，少量与购买权益和试玩资格相关的标记信息存储于系统安全存储区（钥匙串），用于恢复您的已购权益及维持试玩规则，不包含任何个人身份信息；该类标记在卸载本应用后仍可能保留于设备中，或随系统备份恢复。
2. 您主动发送的反馈邮件，原则上在最后一次沟通结束后不超过 12 个月保存；超过该期限后将删除或匿名化处理，法律法规另有要求或为处理争议确有必要的除外。
3. 应用内购买记录由相应应用商店按照其规则保存。本应用在设备本地缓存的解锁状态可随本地数据一并删除，但有效购买权益仍以应用商店记录为准。
六、您的权利
对于您通过反馈邮件主动提供的信息，您可以通过本政策列明的邮箱申请：
1. 查询、复制相关信息；
2. 更正或补充不准确、不完整的信息；
3. 删除相关信息；
4. 撤回此前作出的同意；
5. 对个人信息处理提出咨询、投诉或要求解释说明。
我们将在核实请求后，于适用法律规定的期限内处理。撤回同意不影响撤回前基于同意已经进行的处理活动的效力。
设备本地训练数据由您自行控制。您可以使用应用内已有的删除功能删除相应记录，或通过卸载本应用删除由本应用保存在设备本地的数据（上文所述存储于系统安全存储区的少量标记信息除外）。
七、未成年人保护
本应用不专门面向不满 14 周岁的儿童提供服务。
不满 14 周岁的用户应在监护人指导下使用，不应自行通过意见反馈提交姓名、邮箱、照片、健康信息或其他个人信息；确有必要提交的，应由监护人操作，或在监护人明确同意和指导下进行。
如我们发现未经监护人同意处理了不满 14 周岁儿童的个人信息，将在核实后及时删除。
八、信息安全
我们采取与本应用功能及所处理信息相适应的合理管理和技术措施保护信息安全。但任何存储或传输方式都无法保证绝对安全。
请勿在反馈邮件中提交身份证件、银行卡或支付账号、精确住址、医疗记录或其他与反馈无关的敏感个人信息。
如发生或可能发生个人信息泄露、篡改或丢失，我们将依法采取补救措施，并在法律要求时通知相关用户和主管部门。
九、政策更新
我们可能因功能变化、法律法规或平台要求更新本政策。
一般文字修正、联系方式更新或不影响用户实质权益的调整，可以通过更新日期或应用内通知告知。
如个人信息处理目的、方式、种类、保存期限、共享对象或用户权利发生实质变化，我们将在变更生效前通过应用内显著提示等方式告知，并在法律要求时重新取得您的同意。

Thank you for using Neutral Buoyancy Simulator (the “App”). This Policy explains how the App handles information relating to you.
1. Scope and Personal Information Handler
This Policy applies to the App.
Personal information handler / data controller: Zhang Kunpeng
Email: eagle.zhang2026@qq.com
2. Information Handled by the App
2.1 On-device data
The App stores practice records, high scores, language preferences, codex and unlock progress, settings, agreement acknowledgements, and other data required for local features on your device.
The App does not actively upload this practice and settings data to a server operated by the Developer, and the Developer cannot access it remotely. Whether the data is included in an Apple device backup or iCloud backup depends on your device, operating system, and backup settings. The Developer cannot access your system backups.
2.2 In-app purchases and restoration
If paid unlocking is offered, purchases and restoration are processed by the Apple App Store or another relevant app store. The App may process on the device a product identifier, purchase status, transaction result, or entitlement returned by the app store to unlock or restore features.
The Developer does not receive your card number, Apple Account password, or complete payment details. The current version does not upload purchase receipts to a Developer-operated server. If server validation is introduced, this Policy will be updated before it is enabled and legally required notice will be provided.
2.3 Feedback
When you choose Feedback, the App opens your device’s mail application. The Developer receives information only after you confirm and send the email. This may include your email address, feedback, attachments, and any App information you choose to leave in the message.
The information is used only to respond, troubleshoot, provide after-sales support, and improve the App. It is not used for advertising, profiling, or unrelated purposes.
2.4 Saving result images
When you choose Save to Photos, the App requests the access necessary to add the result image you generated to the system photo library. The App does not intentionally browse, analyze, or upload other photo-library content.
2.5 System sharing and external apps
When you choose Share, the App opens the system share sheet. Content is passed to a third-party app only after you select that app and confirm the action.
The selected app processes the content under its own privacy policy. Opening the share sheet does not mean that the App uploads the content through a Developer-operated server.
3. Accounts, Advertising, Analytics, and Permissions
3.1 The App currently has no account registration or login.
3.2 The App currently contains no third-party advertising and uses no third-party behavioral analytics, advertising tracking, or cross-app tracking tools.
3.3 The App currently does not request location, contacts, camera, or microphone access.
3.4 Audio, video, QR-code generation, and practice-record storage are currently used for on-device features.
3.5 If accounts, cloud sync, advertising, analytics, push notifications, or another feature materially changes information handling, this Policy will be updated before the feature is enabled and any legally required notice or consent will be provided.
4. Sharing, Transfer, and Public Disclosure
We do not sell or rent personal information.
We disclose information only:
4.1 when necessary to complete an action you initiate through a selected sharing app;
4.2 when you send feedback through a mail app;
4.3 when Apple or another app store processes purchases, refunds, or restoration;
4.4 when required by applicable law, legal process, or a lawful request from a competent authority; or
4.5 with your separate consent or as otherwise permitted by law.
If a merger, restructuring, asset transfer, or similar transaction requires transfer of personal information, we will provide legally required notice and require the recipient to continue protecting the information.
5. Retention
5.1 On-device data remains until you delete relevant content using an available in-App deletion feature or uninstall the App. The Developer cannot remotely delete local device data for you.
A small number of markers related to purchase entitlements and trial eligibility are stored in the system secure storage (Keychain). They are used only to restore your purchased entitlements and maintain trial rules, contain no personal identity information, and may remain on the device after the App is uninstalled or be restored from a system backup.
5.2 Feedback emails are generally retained for no longer than 12 months after the last communication, then deleted or anonymized, unless a longer period is required by law or reasonably necessary to resolve a dispute.
5.3 Purchase records are retained by the relevant app store under its rules. A locally cached unlock status may be removed with local App data, while valid entitlement remains determined by the app store record.
6. Your Rights
For information voluntarily submitted by feedback email, you may contact us to request:
6.1 access to and a copy of the information;
6.2 correction or completion;
6.3 deletion;
6.4 withdrawal of consent; or
6.5 an explanation, privacy inquiry, or complaint.
We will verify and respond within the period required by applicable law. Withdrawal does not affect processing lawfully completed before withdrawal.
You control on-device practice data and may delete records through available in-App features or remove data stored by the App by uninstalling it (except the small set of markers held in system secure storage described above).
7. Children
The App is not specifically directed to children under 14.
A user under 14 should use the App with guardian guidance and should not independently submit a name, email address, photo, health information, or other personal information through Feedback. Where submission is necessary, it should be made by a guardian or with the guardian’s express consent and guidance.
If we learn that we processed a child’s information without appropriate guardian consent, we will delete it after verification.
8. Security
We use reasonable administrative and technical safeguards appropriate to the App and information handled. No storage or transmission method can be guaranteed to be completely secure.
Do not include identification documents, card or payment-account details, a precise home address, medical records, or other unnecessary sensitive information in a feedback email.
If personal information is or may be leaked, altered, or lost, we will take remedial measures and provide notice to affected users and authorities where required by law.
9. Policy Updates
We may update this Policy because of feature, legal, regulatory, or platform changes.
Minor wording or contact updates, or changes that do not affect substantive interests, may be communicated through an updated date or in-App notice.
If purposes, methods, categories, retention periods, recipients, or user rights materially change, we will provide prominent notice before the change takes effect and obtain renewed consent where required by law.
