Your records belong to you.
What Quant Life collects
Quant Life does not collect personal data. The app has no account system, advertising, analytics, tracking SDKs, or cloud service. Tracker structures and entries are stored locally inside the app on your iPhone and are not sent to us.
Face ID and device passcode
Quant Life asks iOS to authenticate you before opening your records. Face ID and passcode processing are performed by Apple on your device. Quant Life does not receive or store biometric data.
Exports and sharing
Data leaves the app only when you deliberately use an export or share action. You choose the destination through the iOS share sheet or file picker. Result cards are generated on-device. Shared Quant Life template files contain tracker structure only and do not contain your entries.
Storage, deletion, and backup
You can export a complete JSON backup from Data & Privacy. Quant Life marks its local database to be excluded from iCloud and device backups, so an explicit JSON export is the reliable way to keep a separate copy. You can remove individual entries or trackers in the app. Deleting Quant Life from your iPhone deletes its locally stored app data unless you have separately exported a backup.
Network access and third parties
Core recording and review work offline. Quant Life does not sell personal records, disclose them to advertisers, or use them to build advertising profiles. The app contains no third-party analytics or advertising SDK.
Health and financial information
Quant Life is a general-purpose personal recording tool. It does not provide medical diagnosis, treatment, financial advice, or investment advice. Information you choose to record remains local under the rules described above.
Children
Because Quant Life does not collect personal data, it does not knowingly collect personal data from children. Parents and guardians should decide whether the app and its optional templates are appropriate for a child.
Changes
If the app’s data practices change, this policy and the App Store privacy disclosure will be updated before the new practice is introduced.

你的记录，先属于你。
Quant Life 收集什么
Quant Life 不收集个人数据。App 没有账号系统、广告、分析、追踪 SDK 或云端服务。项目结构与个人记录保存在你的 iPhone 上，不会发送给我们。
Face ID 与设备密码
Quant Life 通过 iOS 在打开记录前验证身份。Face ID 与设备密码由 Apple 在设备上处理；Quant Life 不会获得或保存任何生物识别数据。
导出与分享
只有当你主动选择导出或分享时，数据才会离开 App。你通过 iOS 分享菜单或文件选择器自行决定目的地。结果卡片在设备上生成；分享的 Quant Life 空白模板只包含项目结构，不包含任何个人记录。
保存、删除与备份
你可以在“数据与隐私”中导出完整 JSON 备份。Quant Life 会把本地数据库标记为不进入 iCloud 和设备备份，因此主动导出 JSON 是另行保存数据的可靠方式。你也可以在 App 内删除单条记录或项目。若删除 Quant Life，保存在 App 内的本机数据会随之删除；你此前主动导出的备份不受影响。
网络与第三方
核心记录和回看功能离线可用。Quant Life 不出售个人记录、不向广告商披露记录，也不会用记录建立广告画像。App 不包含第三方分析或广告 SDK。
健康与财富信息
Quant Life 是通用个人记录工具，不提供医疗诊断、治疗、理财或投资建议。你自行选择记录的信息仍按上述规则保存在本机。
儿童
Quant Life 不收集个人数据，因此不会主动收集儿童个人数据。家长或监护人应自行判断 App 与可选模板是否适合儿童使用。
政策变化
如果未来数据处理方式发生变化，我们会在启用新做法前更新本政策和 App Store 隐私披露。
