本政策适用于杭州原子心科技有限公司（以下简称“我们”）提供的 Espresso Formula 2.0 应用及其固件下载、隐私政策页面和支持服务，包括在兼容 Mac 上运行的 iOS 应用。应用用于连接兼容的蓝牙电子秤、压力传感器、温度计等咖啡设备，显示测量数据并保存冲煮记录。

应用目前不要求注册账号。我们不会通过应用主动收集您的通讯录、短信、通话记录、精确位置、广告标识符或手机唯一硬件标识符。

为实现应用功能，应用会在您的设备本地处理和保存：

• 蓝牙设备名称、系统提供的蓝牙标识、设备类型、连接状态、固件版本、设置和故障状态；
• 设备发送的重量、流速、压力、温度、时间和咖啡粉量等测量数据；
• 冲煮记录，以及您填写的咖啡豆、烘焙、设备、研磨、风味和评价等记录内容；
• 语言、主题、屏幕方向、目标值、提示音等应用偏好。

上述内容不会由应用自动上传至 AtomHeart 服务器。旧版 Eclair 固件升级时，您输入的 Wi-Fi 名称和密码会通过蓝牙发送给电子秤，用于电子秤联网下载固件；应用仅在本地保存最后一次成功发送的 Wi-Fi 名称，不将 Wi-Fi 密码持久化保存到应用文件或偏好设置中。本项不表示电子秤自身不会处理或保存其接收的联网信息。

从 1.0 或 1.0.1 原位升级时，应用会在本机读取旧版冲煮记录并转换为新版格式，保存迁移状态、数量和完成时间。迁移不会上传记录，也不会主动删除旧版数据源。

权限提示随系统版本而异，并非表中每项能力都会弹出授权窗口。您可以在系统设置中撤销可管理的权限，但对应功能可能无法继续使用。

应用通过阿里云托管的服务查询和下载固件，不上传您的冲煮记录、Wi-Fi 密码或设备测量数据。下载固件或访问本政策页面时，服务器会自动保存包含 IP 地址、访问时间、请求地址、响应状态及客户端信息的访问与错误日志，用于服务维护、故障排查和安全保障，不用于用户画像、广告或跨应用追踪。

导出、保存和分享由您主动发起，相关文件交由您选择的系统服务或应用处理。系统也可能按您的设置备份应用数据；这些服务适用各自的隐私政策。

通过支持邮箱联系我们时，我们及相应邮件服务提供商会处理您提供的邮件地址、内容和附件，以回复咨询或处理权利请求。请勿发送密码或无关的个人信息。

正式发布版不集成广告、跨应用追踪或第三方用户行为分析 SDK。我们不会出售您的个人信息。

• 冲煮记录、已保存设备和设置保存在本地，可通过应用功能或清除应用数据删除。APP 不持久化保存 Wi-Fi 密码；
• 删除新版记录不会同时清除迁移保留的旧数据、导出文件或系统备份。删除应用及其数据可清除相应本地数据；iOS 的“卸载 App”仍会保留文稿与数据；
• 服务器日志按日归档，归档日志保留约 190 天后自动清理；涉及安全事件或依法需要继续保留的记录除外；
• 支持邮件仅在处理咨询、必要后续沟通或履行法定义务所需期间保存，之后删除或匿名化。服务器日志和邮件不会随删除应用自动清除，您可按第 6 节申请查阅或删除。

已保存到其他应用、相册、云盘或系统备份中的副本，需要在相应服务中另行删除。恢复系统备份可能恢复应用数据。

我们采用应用私有存储、系统权限控制和固件完整性校验等合理措施保护信息，但任何存储或传输方式都无法保证绝对安全。

您可以在应用内查看、编辑、导出或删除冲煮记录，移除已保存设备，并在系统设置中管理权限。对仅保存在您设备上的数据，我们无法远程访问或代为删除；请按第 5 节区分新版记录、旧版数据和备份副本。

对我们持有的信息，您可以通过下方邮箱提出查阅、更正、删除或其他适用权利请求。网站日志不以 APP 账号索引，识别与您有关的条目可能需要您提供访问时间等必要线索；我们会在必要范围内核验请求。不能识别相关信息，或适用法律要求保留时，我们会说明处理限制。撤销系统权限不会自动删除已存在的服务器日志。

Espresso Formula 面向咖啡设备用户，不以儿童为目标用户。未满 14 周岁的儿童应在父母或其他监护人同意和指导下使用。若您认为儿童的信息被不当提供给我们，请联系我们。

我们可能因功能、法律或数据处理方式变化而更新本政策，并在本页面更新日期。重大变更将以适当方式提示；法律要求重新取得同意时，我们会另行征得同意。

This Policy applies to the Espresso Formula 2.0 app and its firmware download, privacy page, and support services provided by Hangzhou AtomHeart Technology Co., Ltd. (“we” or “us”), including the iOS app running on compatible Macs. The app connects to compatible Bluetooth coffee scales, pressure sensors, thermometers, and other coffee devices, displays measurements, and saves brew records.

The app currently does not require an account. It does not actively collect your contacts, messages, call history, precise location, advertising identifiers, or unique mobile hardware identifiers.

To provide app features, Espresso Formula processes and stores locally on your device:

• Bluetooth device names, system-provided Bluetooth identifiers, device types, connection states, firmware versions, settings, and fault states;
• measurements sent by devices, including weight, flow, pressure, temperature, time, and coffee dose;
• brew records and details you enter, such as coffee, roast, equipment, grind, flavor, and evaluation information; and
• app preferences such as language, appearance, orientation, targets, and sound settings.

The app does not automatically upload this information to AtomHeart servers. For the legacy Eclair Wi-Fi update flow, the Wi-Fi name and password you enter are sent to the scale over Bluetooth so it can connect to the network and download firmware. The app stores only the last successfully sent Wi-Fi name locally; it does not persist the password in app files or preferences. This does not mean the scale itself cannot process or store the network information it receives.

When upgrading in place from 1.0 or 1.0.1, the app reads legacy brew records locally, converts them to the new format, and stores migration status, counts, and completion time. Migration does not upload records or actively delete the legacy data source.

Permission prompts vary by system version; not every capability listed produces a permission dialog. You may revoke manageable permissions in system settings, but related features may stop working.

The app checks and downloads firmware through services hosted on Alibaba Cloud without uploading your brew records, Wi-Fi password, or device measurements. Firmware downloads and visits to this Policy page generate access and error logs containing IP addresses, access times, request URLs, response status, and client information for service maintenance, troubleshooting, and security, not for profiling, advertising, or cross-app tracking.

You initiate exports, saving, and sharing, and the files are handled by the system service or app you choose. Your operating system may also back up app data according to your settings. These services are subject to their respective privacy policies.

If you contact our support email, we and the relevant email service providers process your email address, message, and attachments to answer your inquiry or handle a rights request. Please do not send passwords or unrelated personal information.

The public release includes no advertising, cross-app tracking, or third-party behavior analytics SDK. We do not sell your personal information.

• Brew records, remembered devices, and settings are stored locally and can be deleted through app controls or by clearing app data. The app does not persist Wi-Fi passwords.
• Deleting new-format records does not also remove retained legacy data, exports, or system backups. Deleting the app and its data removes the corresponding local data; Offload App on iOS retains documents and data.
• Server logs are archived daily and archived logs are automatically cleared after approximately 190 days, except records that must be retained for security incidents or legal requirements.
• Support emails are kept only as needed to handle inquiries, necessary follow-up, or legal obligations, and are then deleted or anonymized. Deleting the app does not erase server logs or emails; you may request access or deletion as described in Section 6.

Copies in other apps, photo libraries, cloud drives, or system backups must be deleted separately in those services. Restoring a system backup may restore app data.

We use reasonable safeguards such as private app storage, system permission controls, and firmware integrity checks. No storage or transmission method can be guaranteed completely secure.

You can view, edit, export, or delete brew records in the app, remove remembered devices, and manage permissions in system settings. We cannot remotely access or delete data that exists only on your device. See Section 5 for the distinction between new-format records, legacy data, and backups.

For information we hold, you may contact the email below to request access, correction, deletion, or exercise other applicable rights. Website logs are not indexed by an app account, so identifying relevant entries may require necessary details such as the time of access. We will verify requests only as needed and explain limitations if information cannot be identified or must be retained by law. Revoking system permissions does not automatically delete existing server logs.

Espresso Formula is intended for users of coffee equipment and is not directed to children. Children under 14 should use the app only with the consent and guidance of a parent or other guardian. Contact us if you believe a child's information has been provided improperly.

We may update this Policy when app features, law, or data practices change and will update the date on this page. Material changes will be highlighted appropriately, and renewed consent will be requested where required by law.
