Fuelog · 油耗本
本应用（Fuelog 油耗本，下称“本 App”）由独立开发者开发与维护，重视并保护您的隐私。本政策说明本 App 在何种场景会使用您的哪些信息、如何存储以及您拥有的控制权。
一、我们收集与使用的信息
1. 加油记录数据
包括日期、里程表读数、加油量、单价、油号、加油站名称与地址、备注等，由您手动输入或从 CSV 导入。这些信息仅保存在您的设备本地，并通过 Apple iCloud（如您启用）同步到您自己的 iCloud 账户。开发者本人无法读取您的任何记录。
2. 位置信息（仅在您主动使用相关功能时）
仅当您点击“获取附近油价 / 选择加油站位置”等功能时，本 App 会请求一次“使用期间”位置权限。位置数据仅用于：
- 在本地查询当日油价；
- 将您选择的加油地点保存到对应记录。
本 App 不会在后台持续定位，也不会上传位置到任何服务器。
3. 相机与照片
仅当您主动选择“拍照 / 从相册选取 / 保存照片到 Fuelog 相簿”功能时，会请求相应权限。所拍摄或选择的照片：
- 压缩副本保存在您的设备本地，并在您启用 iCloud 时通过 CloudKit 同步到您本人的 iCloud 私有数据库；
- 拍摄时间从
PHAsset.creationDate或图片 EXIF 元数据中读取，用于自动填写日期； - 不会被上传到任何第三方服务器或与第三方共享。
4. 网络访问
本 App 会向公开油价网站发起只读 HTTP/HTTPS 请求以获取油价信息。该请求不携带任何用户标识，不会上传您的任何记录、位置或个人信息。
二、我们不收集的信息
本 App 不接入任何第三方广告、统计、崩溃上报 SDK；不收集 IDFA、设备指纹、邮箱、手机号、通讯录、健康数据；不进行任何形式的跨 App 跟踪。
关于 Fuelog Pro 内购：购买流程完全由 Apple StoreKit 处理，交易凭据保存在您本人的 Apple ID 与设备上。本 App 仅在本地保存一个 isPro 布尔值用于判断是否已解锁会员权益，不上传任何购买凭据或账户信息到开发者服务器。
三、数据存储与同步
所有记录通过 SwiftData 存储于 iOS 沙盒，并在您启用 iCloud 时由系统自动同步到您本人的 iCloud 私有数据库。开发者本人和任何第三方都无法访问该数据库。
四、您的控制权
您可以随时：
- 在“设置 → 数据管理 → 导出 CSV”中导出全部数据；
- 在“设置 → 数据管理 → 清除当前车辆记录”中删除当前车辆的全部本地数据；
- 通过 iOS 系统“设置 → 隐私”撤回任何单项权限；
- 通过 iOS“设置 → 您的 Apple ID → iCloud → 管理账户存储 → Fuelog”删除云端数据；
- 在 iOS“设置 → 通用 → iPhone 储存空间 → Fuelog → 删除 App”中彻底卸载并清除本地数据。
五、儿童隐私
本 App 不面向 13 周岁以下儿童，亦不会主动收集任何儿童信息。
六、政策变更
本政策如有更新，将在 App 内“设置 → 隐私政策”中以新的“最后更新日期”呈现。继续使用本 App 视为接受变更后的政策。
七、联系我们
如有任何关于隐私的问题，可在 App Store 评论页留言反馈。
八、开源组件
本 App 包含以下开源组件：
- ZIPFoundation（MIT License）—— 用于完整备份的 zip 打包与解包。版权所有 © Thomas Zoechling，许可证详见 GitHub。
除上述组件外，本 App 仅使用 Apple 官方框架（SwiftUI / SwiftData / CloudKit / MapKit / CoreLocation / Photos / StoreKit）。
This application ("Fuelog", the "App") is developed and maintained by an independent developer who respects your privacy. This Policy describes what information the App processes, how it is stored, and the controls available to you.
1. Information We Use
1.1 Fueling Records
Date, odometer reading, fuel amount, unit price, fuel grade, station name & address, notes — all entered or imported by you. The data is stored locally on your device and, if enabled, synced through Apple iCloud to your personal iCloud account. The developer cannot read any of your records.
1.2 Location (only when you invoke related features)
Only when you tap "Look up nearby fuel price" or "Pick station location" the App requests "While Using" location permission. Location is used solely to:
- Query daily fuel prices locally;
- Save the chosen fueling location to the related record.
The App never tracks you in the background or uploads location data to any server.
1.3 Camera & Photos
Only when you actively choose "Capture / Pick from Library / Save to Fuelog Album" features. Captured or selected photos:
- A compressed copy is stored locally on your device and, if iCloud is enabled, synced to your personal iCloud private database via CloudKit;
- The capture time is read from
PHAsset.creationDateor EXIF metadata to auto-fill the record date; - They are never uploaded to any third-party server or shared with any third party.
1.4 Network Access
The App performs read-only HTTP/HTTPS requests to public fuel-price websites in order to retrieve pricing information. These requests carry no user identifier and never upload any of your records, locations, or personal data.
2. Information We Do Not Collect
The App integrates no third-party advertising, analytics, or crash-reporting SDK. It collects no IDFA, device fingerprint, email, phone number, contact list, or health data, and performs no cross-app tracking.
Regarding Fuelog Pro in-app purchase: the purchase flow is handled entirely by Apple StoreKit, and transaction receipts are stored on your own Apple ID and device. The App only keeps a local isPro boolean to determine whether Pro entitlement is unlocked — no purchase receipt or account information is ever uploaded to the developer's server.
3. Storage & Sync
All records are stored locally via SwiftData, and synced (only if you enable iCloud) to your personal CloudKit private database. Neither the developer nor any third party can access that database.
4. Your Controls
You may at any time:
- Export all data via "Settings → Data → Export CSV";
- Delete all data of the currently selected vehicle via "Settings → Data → Erase Current Vehicle";
- Revoke any permission via iOS "Settings → Privacy";
- Remove cloud data via iOS "Settings → Apple ID → iCloud → Manage Account Storage → Fuelog";
- Uninstall the App completely via iOS "Settings → General → iPhone Storage".
5. Children's Privacy
The App is not directed at children under 13 and does not knowingly collect data from children.
6. Changes
Updates to this Policy will be reflected by a new "Last Updated" date inside the App. Continued use constitutes acceptance.
7. Contact
For privacy questions please leave a message on the App Store review page.
8. Open-Source Components
The App bundles the following open-source component:
- ZIPFoundation (MIT License) — used for zip archive packing/unpacking in full backups. Copyright © Thomas Zoechling. License available on GitHub.
Besides the above, the App only uses Apple-provided frameworks (SwiftUI / SwiftData / CloudKit / MapKit / CoreLocation / Photos / StoreKit).
