Chi Sensor may include third-party components or services; your use of them is also subject to the applicable third party’s terms.

5. Disclaimer and Limitation of Liability

You choose to use Chi Sensor based on your own needs and accept the risks associated with that use to the extent permitted by law. Although Chi Sensor is tested, the Company cannot guarantee compatibility with every hardware or software configuration or guarantee that the app will always be error-free or uninterrupted. If you encounter a compatibility issue or error, contact Chi Sensor Support. You may need to update or uninstall Chi Sensor or use a compatible device. Third-party services are governed by their own terms. You are responsible for maintaining any backups you require. The Company does not guarantee permanent data retention and may delete data if a service is discontinued, subject to applicable law and the retention commitments in this Policy.

6. Privacy and Experience Analytics

This section was updated and takes effect on July 27, 2026.

During a room scan, camera video is processed on your device to assess motion, sharpness, exposure, and room coverage; the raw video is not uploaded. Chi Sensor usually selects 6–10 clear still photos (at least four are required to submit) and uploads those photos together with a compact RoomPlan description of walls, doors, windows, furniture, camera poses, and scan-quality measurements for report generation.

For V4 and V5 scan submissions, selected photos and available room structure are processed by Chi Sensor servers and may be transmitted to contracted AI infrastructure and model providers only to generate the report, AI explanations, and remedy previews you request. The current service uses OpenRouter to route requests to the model provider selected for a feature; those providers may include Google, OpenAI, and Black Forest Labs depending on the feature and production configuration. Only the scan content needed to provide the requested feature is sent to these providers, whose processing is also governed by their applicable terms and data-protection commitments.

All still source photos uploaded through V4 or V5 are encrypted for server-side storage and retained for no more than seven days from receipt; the same maximum period applies if analysis fails. These source photos are used only to complete analysis, generate report evidence or requested remedy previews, and support a retry or regeneration during that period. They are deleted when the period expires. If required encryption is unavailable, the scan is not accepted and source photos are not retained in plaintext. Original before photos for the current scan may also remain in Chi Sensor’s private on-device storage and are not exposed through a public URL. Deleting an account removes the linked account, report, and generated-visual records; temporary encrypted scan sources are deleted no later than the existing seven-day limit.

When you first launch Chi Sensor, we separately ask whether you allow Experience Analytics. Before you expressly choose to allow it, Chi Sensor does not record, queue locally, or send experience analytics events. Declining Experience Analytics does not prevent you from using scanning, reports, or other core features.

If you allow it, our servers receive first-party product interaction events that help us understand screen use, scanning and analysis success or abandonment, report and AI feature feedback, purchase flows, and pseudonymous retention. Chi Sensor creates random installation and session identifiers on your device. The server stores them only after applying a keyed one-way hash (HMAC). These pseudonymous identifiers are not linked to your Chi Sensor account and are not used to combine activity across devices.

Experience events may include the app and operating-system version, language, device-capability category, guest or signed-in status category, screen, standardized action, product identifier, duration, standardized failure code, and a fixed feedback reason that you select. The first-party experience event table does not store your account ID, email, name, phone number, or IP address; event payloads also do not contain room images or structure, report or AI text, transaction identifiers, credentials, tokens, or raw error responses. First-party experience events are retained for no more than 90 days from when they occur and are then deleted. Operations personnel can access only aggregate metrics and pseudonymous single-session timelines.

You can turn analytics off at any time under “More > Privacy & Analytics” in Chi Sensor. Turning it off stops new first-party collection, clears events that have not yet been sent, and stops Singular tracking within Chi Sensor. On the same screen, you can request deletion of the first-party experience data associated with that installation identifier; this deletion control applies only to first-party experience data. After deletion succeeds, a new random installation identifier will be used if you later allow analytics again.

Separately from our first-party experience analytics, Chi Sensor uses Singular to process device and interaction data for app analytics, installation attribution, and advertising measurement. Where required, iOS App Tracking Transparency controls access to the advertising identifier; refusing tracking does not prevent use of Chi Sensor’s core features. Singular’s processing and retention are also governed by its own privacy terms and are not represented as part of the first-party 90-day retention period described above.

7. Miscellaneous Provisions

If any part of these Terms is found invalid or unenforceable, the remaining provisions remain in effect. Any dispute between you and the Company should first be addressed through good-faith negotiation. If the dispute cannot be resolved, either party may submit it to a court with jurisdiction where the Company is located. The Company may interpret and update these Terms to the extent permitted by law.

五、免责与责任限制

在法律允许的范围内，您根据自身需要选择使用 Chi Sensor，并承担由此产生的相关风险。Chi Sensor 已经过测试，但本公司无法保证其兼容所有软硬件环境，也无法保证 App 始终无错误或不中断。如遇到兼容或运行问题，请联系 Chi Sensor 帮助中心；您可能需要升级或卸载 Chi Sensor，或更换兼容设备。第三方服务受其自身条款约束。您应根据需要自行备份数据。本公司不保证永久保存数据；如服务终止，可能会在遵守适用法律及本政策所述保存期限的前提下删除相关数据。

六、隐私与体验分析

本节更新并生效于 2026 年 7 月 27 日。

房间扫描期间，相机视频仅在设备本地用于判断移动速度、清晰度、曝光和空间覆盖度，原始视频不会上传。Chi Sensor 通常会自动筛选 6–10 张清晰静态照片（至少 4 张方可提交），并将这些照片与精简的 RoomPlan 空间结构一并上传，用于生成报告；空间结构可能包含墙、门、窗、家具、相机姿态及扫描质量数据。

对于 V4 和 V5 扫描提交，所选照片及可用的房间结构会由 Chi Sensor 服务器处理，并可能仅为生成您请求的报告、AI 说明及改善预览而发送给受托的 AI 基础设施和模型服务商。当前服务通过 OpenRouter 将请求路由至相应功能所选用的模型服务商；根据具体功能和生产配置，这些服务商可能包括 Google、OpenAI 和 Black Forest Labs。我们仅发送完成所请求功能所必需的扫描内容，相关服务商的处理同时受其适用条款及数据保护承诺约束。

通过 V4 或 V5 上传的所有静态原图均以加密形式在服务端存储，自服务端接收之日起保留不超过 7 天；即使分析失败，也适用同一最长期限。这些原图仅用于完成分析、生成报告证据或您请求的改善预览，以及在该期限内支持重试或重新生成，并在期限届满时删除。若服务端无法启用必要的加密，扫描将不会被接收，原图也不会以明文形式留存。当前扫描的 Before 原图也可能保存在 App 的设备私有目录中，不会通过公开 URL 提供。删除账号会删除与账号关联的账号、报告和生成视觉记录；临时加密扫描原图最迟仍会在既有的 7 天期限内删除。

首次启动 Chi Sensor 时，我们会单独询问您是否允许“体验分析”。在您明确选择允许前，Chi Sensor 不会记录、本地排队或发送体验分析事件。拒绝体验分析不影响扫描、报告或其他核心功能。

您允许后，我们的服务器会接收首方产品互动事件，用于分析页面使用、扫描与分析成功或放弃、报告和 AI 功能反馈、付费流程及假名化的安装级留存。我们会在设备上生成随机安装标识和会话标识，服务器使用单向密钥哈希（HMAC）后存储。这些假名化标识不与 Chi Sensor 账号关联，不用于跨设备合并行为。

体验事件可包含 App 与系统版本、语言、设备能力类别、游客或登录状态类别、页面、标准化动作、商品标识、耗时、标准化失败码及您选择的固定反馈原因。首方体验事件表不保存账号 ID、邮箱、姓名、电话或 IP 地址；体验事件本身也不包含房间图片或结构、报告或 AI 文本、交易标识、凭证、Token 或原始错误响应。首方体验事件自发生之日起最多保留 90 天，期满后删除；运营人员只能查看聚合指标和假名化的单会话时间线。

您可随时在 Chi Sensor 的“More > Privacy & Analytics（更多 > 隐私与分析）”中关闭分析。关闭后，Chi Sensor 会停止新的首方事件收集、清除未发送队列，并停止 Singular 在 App 内的追踪。您也可在同一页面请求删除该安装标识对应的首方体验数据；此删除功能仅适用于首方体验数据。删除成功后，如您之后重新允许，将使用新的随机安装标识。

除首方体验分析外，Chi Sensor 还使用 Singular 处理设备与交互数据，以进行应用分析、安装归因和广告效果衡量。在适用情况下，iOS“App 跟踪透明度”（ATT）决定是否允许访问广告标识符；拒绝跟踪不影响核心功能。Singular 的处理和保留同时受其自身隐私条款约束，不与上述首方 90 天保留期混为同一口径。

七、其他条款

如本条款的任何部分被认定无效或不可执行，不影响其他条款的效力。您与本公司之间发生争议时，双方应先本着善意协商解决；协商无法解决的，任何一方均可向本公司所在地有管辖权的法院提起诉讼。本公司可在法律允许的范围内解释和更新本条款。
