概述
「律己绿生活」(英文名 GreenTrace,以下简称"本应用")是一款专注于「个人碳足迹记录、情景模拟与可持续挑战打卡」的离线生活方式工具,由「律己绿生活 团队」(以下简称"我们")开发与运营。我们高度重视您的隐私保护。本隐私政策说明本应用如何处理您的信息。
信息收集
本应用不收集任何个人信息。
具体来说:
- 不收集姓名、邮箱、电话等个人身份信息
- 不收集设备标识符(IDFA、UUID 等)
- 不收集位置信息
- 不收集使用行为数据
- 不使用任何分析或追踪服务
- 不包含第三方 SDK
数据存储
本应用的所有数据均存储在您的设备本地:
- 碳足迹记录(分类、项目、数量、单位、备注、估算的 kgCO₂e、时间)
- 挑战打卡记录(挑战 ID、打卡时间)
- 情景模拟器状态(4 个滑块当前数值)
- 设置项(月减排目标、本地提醒开关与时间、引导是否完成)
- 本地事件日志(仅记录"启动 / 添加记录 / 打卡 / 设置变更"等不含内容明细的本机审计行)
这些数据:
- 仅存储在您的设备上(使用 iOS
UserDefaults与 App 沙盒内的records.json、challenges.json、events.log) - 不会上传到任何服务器
- 不会与任何第三方共享
- 随应用卸载而删除
网络连接
本应用完全离线运行,不使用任何网络连接。
排放因子库、等效换算系数、挑战种子均为应用内置的本地 JSON 资源与算法。
第三方服务
本应用不包含任何第三方服务或 SDK,不集成广告网络、不使用统计分析、不使用崩溃上报、不使用社交账号登录、不使用云同步。
系统权限
- 通知:仅当您在「设置 → 每日提醒记录碳足迹」中主动开启时,本应用才会请求系统通知权限。通知由 iOS 在您指定的时间本地触发,不经过任何服务器。您可随时关闭。
- 其他:本应用不申请相机、相册、定位、麦克风、联系人、健康、运动等任何其他权限。
数据导出
应用提供「导出 CSV」功能,将您本机的碳足迹记录写入应用沙盒中的 greentrace_records.csv,并通过 iOS 系统分享面板(UIActivityViewController)由您自主决定保存位置或发送对象。本应用本身不上传、不留存、不读取导出后的副本。
排放因子与减排估算
本应用展示的 kgCO₂e 数值为基于公开数据(IPCC AR6、Poore & Nemecek 2018 Science、UK DEFRA 2023 排放因子库、中国生态环境部《公民绿色低碳行为温室气体减排量化方法》、国家发改委区域电网平均因子等)的估算值,仅供个人参考,不可用于碳交易、企业核算或正式 ESG 报告。
跟踪透明度(ATT)
本应用不进行任何形式的用户跟踪,不会弹出 ATT 授权请求。提交至 App Store Connect 时已声明 NSPrivacyTracking = false,并附 PrivacyInfo.xcprivacy 隐私清单声明零数据收集。
儿童隐私
本应用不会故意收集 13 岁以下儿童的任何信息。由于本应用根本不收集任何信息,因此适合所有年龄段使用。
数据安全
由于本应用不收集或传输任何数据,因此不存在数据泄露风险。所有数据仅存储在您的设备上,受您设备的安全机制(沙盒、文件系统加密等)保护。
您的权利
您可以随时:
- 通过卸载应用删除所有本地数据
- 在 App 内「设置 → 清空所有数据」一次性清除碳足迹记录、挑战打卡、本地事件日志,并重置目标与提醒
- 在 App 内「设置 → 每日提醒记录碳足迹」关闭通知;或通过 iOS「设置 → 通知 → 律己绿生活」管理通知权限
隐私政策变更
我们可能会不时更新本隐私政策。任何变更将通过应用更新通知您。建议您定期查看本政策。当前 v1.0 承诺保持完全离线。

Overview
"GreenTrace" (Chinese name 律己绿生活, the "App") is an offline lifestyle tool focused on personal carbon-footprint logging, scenario simulation, and sustainability challenge check-ins, developed and operated by the GreenTrace Team (the "We"). We take your privacy seriously. This Privacy Policy explains how the App handles your information.
Information Collection
The App does not collect any personal information.
Specifically:
- No collection of names, emails, phone numbers, or other personal identifiers
- No collection of device identifiers (IDFA, UUID, etc.)
- No collection of location data
- No collection of usage behavior data
- No use of analytics or tracking services
- No third-party SDKs
Data Storage
All App data is stored locally on your device:
- Carbon-footprint records (category, item, quantity, unit, note, estimated kgCO₂e, timestamp)
- Challenge check-ins (challenge ID, check-in timestamp)
- Simulator state (current values of the 4 sliders)
- Settings (monthly reduction goal, local-reminder toggle and time, onboarding flag)
- Local event log (an on-device audit trail of events such as "app_launch / record_added / challenge_checkin / setting_changed", without record content)
This data:
- Is stored only on your device (in iOS
UserDefaultsand the app sandbox filesrecords.json,challenges.json,events.log) - Is not uploaded to any server
- Is not shared with any third party
- Is deleted when you uninstall the App
Network Connection
The App runs completely offline and does not use any network connection.
The emission-factor library, equivalence constants, and challenge seeds are all bundled local JSON resources and algorithms.
Third-Party Services
The App does not include any third-party services or SDKs, no ad networks, no analytics, no crash reporting, no social sign-in, and no cloud sync.
System Permissions
- Notifications: Only when you actively enable "Daily reminder to log your footprint" in Settings does the App request the system notification permission. Reminders are scheduled locally by iOS at the time you choose and never pass through any server. You may disable them at any time.
- Other: The App requests no camera, photos, location, microphone, contacts, health, or motion permissions.
Data Export
The App provides a "Export CSV" feature that writes your on-device records to greentrace_records.csv inside the app sandbox and presents the iOS system share sheet (UIActivityViewController) so that you choose where to save or send it. The App itself never uploads, retains, or re-reads the exported copy.
Emission Factors & Reduction Estimates
The kgCO₂e values shown by the App are estimates based on public data (IPCC AR6; Poore & Nemecek, Science 2018; UK DEFRA 2023 emission factors; China MEE Citizen Low-Carbon Behavior Quantification Method; NDRC regional grid averages, etc.) for personal reference only. They must not be used for carbon trading, corporate accounting, or formal ESG reporting.
App Tracking Transparency (ATT)
The App performs no tracking and does not show an ATT prompt. The submission declares NSPrivacyTracking = false and ships a PrivacyInfo.xcprivacy manifest stating zero data collection.
Children's Privacy
The App does not knowingly collect any information from children under 13. Since the App does not collect any information at all, it is suitable for all ages.
Data Security
Since the App does not collect or transmit any data, there is no risk of data breach. All data is stored on your device and protected by your device's security mechanisms (sandbox, file-system encryption, etc.).
Your Rights
You can at any time:
- Delete all local data by uninstalling the App
- Wipe all carbon-footprint records, challenge check-ins, and the local event log, and reset your goal and reminder via "Settings → Clear All Data" inside the App
- Disable reminders via "Settings → Daily reminder", or manage notification permissions via iOS "Settings → Notifications → 律己绿生活"
Changes to Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be communicated through app updates. We recommend reviewing this policy regularly. The current v1.0 commits to remaining fully offline.
