到期本 · Expiry

一、我们如何存储您的数据 How your data is stored

到期本(以下简称"本应用")是一款完全本地的 iOS 应用。 您在本应用中输入的所有内容——档案标题、到期日、金额、凭证图片、备注、续保记录等—— 仅保存在您本人使用的这台 iPhone / iPad 的应用沙盒(App Sandbox)内。

本应用没有服务器,也不会通过网络上传您的任何数据。 唯一的联网请求是向 Apple StoreKit 验证您的 App Store 购买记录(用于 Pro 版本解锁), 这一过程由 Apple 官方系统组件完成,本应用无法读取到您的 Apple ID 或购买明细以外的信息。

如果您使用 iCloud Backup 备份您的 iPhone,您的档案数据会随备份一同存储在您的 Apple iCloud 空间中, 这一过程由 iOS 系统管理,本应用不参与、不干预。

二、我们请求的系统权限 Permissions we request

• 相册读取(Photo Library) —— 当您为档案添加凭证时请求。所选照片会压缩后保存在应用沙盒内,不会写回相册,也不会上传。
• 相册写入(Photo Library Add) —— 仅在您主动点击"保存到相册"时请求,用于将凭证图片另存至您的相册。
• 通知(Notifications) —— 在您添加第一份档案后请求。仅用于本地日历提醒(到期日提前提醒 + 每日晨间摘要), 通知内容不发送到任何服务器。

您可以在 iOS 系统"设置 → 到期本"中随时撤销上述任一权限。撤销后相关功能不可用,但不影响其他功能。

三、Pro 内购与家庭共享 In-app purchase & Family Sharing

本应用提供一次性内购"到期本 Pro"(产品 ID:com.xun.expiry.pro)。 该内购由 Apple App Store 系统处理,支持家庭共享(Family Sharing)。

本应用不接收也不保存您的支付信息(如银行卡号、Apple ID 密码等)。 本应用仅通过 Apple 官方 StoreKit 接口收到"已购买"这一布尔状态,以便解锁 Pro 功能。

四、数据导出与删除 Export & Deletion

您可以随时通过应用内"我 → 导出数据"将全部档案导出为 CSV 文件,供您自行备份或迁移至其他工具。

您可以随时通过 iOS 长按图标 → 删除 App 的方式清空本应用的全部数据。 由于本应用不联网,删除即销毁,我们没有任何备份可以为您恢复。 建议您定期使用应用内的"导出数据"功能自行备份。

五、儿童隐私 Children's Privacy

本应用不面向 13 岁以下儿童,也不主动收集任何个人身份信息。 如果您是家长/监护人,发现您的孩子在使用本应用,请通过下方邮箱联系我们。

1. How your data is stored

Expiry (the "App") is a fully local iOS application. All content you enter into the App — archive titles, expiry dates, amounts, receipt photos, notes, renewal history — is stored only inside the App Sandbox on the iPhone or iPad you are using.

The App has no server and does not upload any of your data over the network. The only network activity is a call to Apple StoreKit to verify your App Store purchase for Pro unlocking. This is handled by Apple's system components; the App cannot access anything beyond a boolean "purchased" status.

If you use iCloud Backup, your data may be included in that backup within your own iCloud space. This is managed by iOS and is outside the App's control.

2. Permissions we request

• Photo Library (read) — requested when you add a photo receipt to an archive. Selected photos are compressed and stored inside the App Sandbox. They are not written back to your library, and are not uploaded.
• Photo Library (write) — requested only when you explicitly tap "save to Photos" for a receipt.
• Notifications — requested after you save your first archive. Used solely for local reminders (advance-notice on expiry dates + a daily morning digest). Notification content is never sent to any server.

You can revoke any of the above permissions at any time via iOS Settings → Expiry. The affected feature will stop working, but the rest of the App is unaffected.

3. In-app purchase & Family Sharing

The App offers a single one-time in-app purchase, "Expiry Pro" (product ID com.xun.expiry.pro). The transaction is processed entirely by Apple App Store and supports Family Sharing.

The App does not receive or store your payment credentials (card numbers, Apple ID password, etc.). The App only receives a "purchased" status from Apple's StoreKit to unlock Pro features.

4. Data export & deletion

You can export all your archives to a CSV file at any time via "Me → Export Data" inside the App, for your own backup or migration.

You can wipe all App data at any time by long-pressing the App icon on iOS and choosing Delete App. Because the App has no network component, deletion is irreversible — no backups exist on our side. We recommend using the in-app Export function to keep your own backups.

5. Children's Privacy

The App is not directed at children under 13, and does not knowingly collect any personally identifiable information. Parents / guardians who discover their child is using the App may contact us via the email below.

6. Changes to this Policy

Any updates to this Privacy Policy will be published on this page with a revised "Last Updated" date at the top. Material changes will also be surfaced in the App's release notes.
