Accelio Privacy Policy

Last updated: November 12, 2026 · Developer: Shanghai Mizong Network Technology Co., Ltd.

Summary: Accelio is an offline-first motion data logger and signal analysis tool. We do not operate user accounts, cloud databases, analytics trackers, or advertising SDKs. We collect zero personal data or sensor recordings on developer servers.

1. Data We Collect

None. Accelio does not collect, transmit, store, or sell any personal information, device identifiers, location data, usage telemetry, or motion recordings to Shanghai Mizong Network Technology Co., Ltd. or any third party on our behalf.

2. On-Device Sensor Processing & Storage

Motion Sensor Readings: Accelerometer and Device Motion readings accessed via Apple's Core Motion framework are processed in real time on your iPhone and saved exclusively in the app's local sandboxed container when you start a recording.
User Exports: Recordings leave your device only when you explicitly export or share them (as CSV, JSON, or .accelio packages) using the system share sheet or the Files app.
Retention & Deletion: You have full control over local storage. You can delete individual recordings, configure automatic local retention periods (30 days, 90 days, 1 year, or Forever), or tap Delete All Recordings in Settings at any time.

3. Optional Bring-Your-Own-Key (BYOK) AI Analysis

All core measurement, recording, timeline, spectral analysis (FFT/PSD/STFT), filtering, and export features work completely offline without configuring any AI service.
If you choose to configure a third-party OpenAI-compatible AI endpoint in Settings:
- Your API key is stored solely on your device inside the encrypted iOS Keychain and is never written to logs or exported files. You can delete it at any time in Settings.
- Before your first AI request, Accelio asks for your explicit consent, and every request displays a transparent preview of the provider and payload size.
- Raw high-frequency time-series arrays are never uploaded. Only compact session metadata and locally computed statistics, peaks, or spectral summaries are sent directly from your iPhone to the endpoint you configured, governed by that provider's own privacy policy.

4. Third-Party SDKs & Tracking

Accelio embeds zero third-party SDKs, zero analytics libraries, and zero advertising frameworks, and never requests App Tracking Transparency permissions.

5. Children's Privacy

Accelio is a general-audience scientific and engineering utility and does not knowingly collect personal information from anyone, including children.

6. Changes & Contact

Material updates to this policy will be reflected on this page and in App Store release notes. For privacy questions or support, contact us at helixzz@helixzz.com.

Accelio 隐私政策

最后更新：2026 年 11 月 12 日 · 开发者：上海觅踪网络科技有限公司（Shanghai Mizong Network Technology Co., Ltd.）

核心摘要：Accelio 是一款离线优先的便携式运动数据记录与信号分析工具。本应用不设用户账号体系、不设开发者云端数据库、不含任何统计分析或广告追踪 SDK，开发者服务器不收集任何个人信息或传感器记录数据。

1. 我们收集哪些信息

不收集任何信息。上海觅踪网络科技有限公司不会收集、上传、存储、共享或出售你的任何个人身份信息、设备标识符、位置数据、使用行为遥测或运动传感器记录。

2. 设备端传感器处理与本地存储

运动传感器读数：应用通过 iOS 系统 Core Motion 框架读取的三轴加速度与设备运动数据，仅在你的 iPhone 本地实时展示，并在你主动点击「开始录制」时保存在本机应用沙盒目录中。
数据导出与分享：只有当你主动调用系统分享面板或「文件」应用导出（CSV、JSON 或 .accelio 记录包）时，相应文件才会按你的指令离开应用沙盒。
数据保留与删除：本地数据完全由你掌控。你可随时删除单条记录、配置自动保留期限（永久、30 天、90 天或 1 年），或在「设置」中点击「删除全部记录」一键彻底清空。

3. 可选的自带密钥（BYOK）AI 分析功能

应用的全部测量、录制、时间线截取、频谱与滤波分析（FFT/PSD/STFT）及数据导出功能均可 100% 离线独立运行，无需联网或配置 AI 服务。
仅当你在「设置」中主动配置第三方兼容模型接口并使用「问问 Accelio」时：
- 你输入的 API 密钥仅加密保存在本机系统的 iOS 钥匙串（Keychain） 中，绝不写入日志或导出文件，且可随时在设置中一键删除并重置授权。
- 首次发起请求前需经你明确知情同意，且每次提问前界面均透明展示目标服务商名称与摘要字节数。
- 绝不上传原始高频采样点序列：应用仅在本地通过确定性算法提取统计指标、峰值或频谱特征摘要，由你的设备直连发送至你自行配置的服务商接口，相关处理适用该服务商自身的隐私政策。

4. 第三方 SDK 与追踪声明

Accelio 不集成任何第三方 SDK、广告框架或行为统计组件，不进行任何跨应用追踪。

5. 未成年人保护

本应用为通用型科学与工程测量工具，不会收集包括未成年人在内的任何用户的个人信息。

6. 政策更新与联系方式

若本政策发生重大变更，我们将在本页面及版本更新说明中同步公示。如有任何隐私相关疑问或技术支持需求，请联系：helixzz@helixzz.com。
