隐私政策
生效日期：2026 年 9 月 3 日
我们不收集你的数据
成本小账不要求注册应用账户，不接入广告、分析或追踪 SDK，也不会把你的配方、原材料、备注或使用记录发送到开发者运营的服务器。
数据保存与同步
原材料、配方和备注保存在你的设备上，并通过 Apple CloudKit 存入你的 iCloud 私有数据库，在登录同一 Apple ID 的设备间自动同步。开发者不运营用于接收这些数据的服务器。Apple 对 iCloud 的处理受 Apple 隐私政策约束。
导出与分享
只有在你主动导出备份或分享摘要时，相关数据才会交给你选择的文件位置、文件提供商或接收方。导出的 JSON 文件不加密，可能包含经营信息，请妥善保管。第三方文件服务和接收方按其各自政策处理数据。
保留、删除与控制
数据会保留至你在应用内删除。删除会通过 iCloud 同步到同一 Apple ID 的其他设备。卸载应用不一定会删除 iCloud 中的同步数据，也不会删除你已导出、分享或由系统备份的文件；你可以在应用或 Apple 系统设置中管理这些数据。
儿童隐私与政策变更
本应用不以儿童为目标，也不会主动收集儿童个人信息。若应用的数据实践发生变化，我们会更新本页的内容与生效日期。

Privacy Policy
Effective: September 3, 2026
No developer data collection
Cost Ledger does not require an app account and includes no advertising, analytics, or tracking SDKs. Your recipes, ingredients, notes, and usage activity are not sent to a developer-operated server.
Storage and sync
Ingredients, recipes, and notes are stored on your device and in your private iCloud database through Apple CloudKit, syncing across devices signed in to the same Apple ID. The developer does not operate a server that receives this data. Apple's handling of iCloud data is governed by Apple's privacy policy.
Export and sharing
Data is provided to a location, file provider, or recipient only when you choose to export a backup or share a summary. Exported JSON files are not encrypted and may contain business information. Third-party services and recipients process data under their own policies.
Retention, deletion, and control
Data remains until you delete it in the app. Deletions sync to your other devices through iCloud. Uninstalling the app may not remove synced iCloud data or files you previously exported, shared, or backed up. You can manage this data in the app and Apple system settings.
Children and changes
The app is not directed to children and does not knowingly collect children's personal information. If the app's data practices change, this page and its effective date will be updated.
Contact
For privacy or data questions, use the public support page. Do not post recipes, ledger data, or other sensitive business information in a public issue.
