四川聿嘉睿软件科技有限公司（以下简称"我们"）深知个人信息对您的重要性，并会尽全力保护您的个人信息安全可靠。我们致力于维持您对我们的信任，恪守以下原则保护您的个人信息：权责一致、目的明确、选择同意、最小必要、确保安全、主体参与、公开透明。
FuturePost Unlock 是一款加密时间胶囊二维码工具。我们的核心设计原则是：您输入的内容与生成的加密二维码仅存于您的设备本地，不经任何服务器中转，我们也无法访问您锁入胶囊的内容。请您在使用 FuturePost Unlock（以下简称"本应用"）前，仔细阅读并充分理解本隐私政策。
为了提供加密时间胶囊与扫码功能，本应用会在您的设备上处理以下数据（这些数据仅保存在您的设备本地，不会发送到任何地方）：
| 数据 | 用途 | 存储位置 |
|---|---|---|
| 您在创建页输入的文字内容 | 用于 AES-256-GCM 加密并生成二维码；加密后原文即从内存清除 | 仅存在于运行内存，不写入持久化存储 |
| 生成的二维码图像（保存到相册时） | 便于您将二维码分享给他人或在其他设备上扫描 | 仅当您主动点击"保存到相册"后写入系统相册 |
| 扫码结果（仅在扫码后短暂显示） | 解锁后向您展示原始内容 | 仅存在于运行内存，关闭页面即清除 |
| 应用偏好设置（如界面语言等） | 保存您的个性化配置 | 应用偏好设置（UserDefaults） |
| 设备系统运行时间信息 | 检测可能的时间篡改，确保倒计时准确 | 仅用于本地校验，不存储、不传输 |
本应用仅在您主动触发对应功能时才会请求相关权限，不会在后台访问：
我们仅在您设备本地使用上述信息，用于：
我们不会将您的任何信息用于广告、用户画像、营销或任何与上述功能无关的目的。
您主动保存到相册并自行分享给他人的二维码，属于您个人的分享行为，由您自行承担相应责任。二维码本身经过 AES-256-GCM 加密，未到解锁时间任何第三方扫码工具均无法读取内容。
futurecode://unlock 私有 URL Scheme，仅本应用可识别与解密。本应用处理的所有数据均存储在您的设备本地（运行内存、相册、应用偏好设置），不经过、不存储于我们的任何服务器。您输入的原文在加密生成二维码后即从内存清除；扫码解锁后展示的内容也仅存在于运行内存，关闭页面即清除。卸载应用即可完全移除本应用产生的全部本地数据。
为防止用户通过调整系统时间提前解锁，本应用结合设备系统运行时间信息进行本地校验。该校验完全在您的设备上离线完成，不会收集、不会传输任何个人身份信息。
您可以随时对您的数据行使以下权利：
本应用不针对未满 18 周岁的未成年人，也不主动收集未成年人的个人信息。若您是未成年人，请在监护人的陪同下使用本应用。监护人应指导未成年人合理使用加密与扫码功能，并注意不要在时间胶囊中放入违法或不当内容。
我们可能适时对本隐私政策进行修订。若政策发生重大变更，我们将在应用内或通过官方网站以显著方式通知您。政策更新后继续使用本应用，即表示您接受更新后的政策。
如您对本隐私政策或数据处理事宜有任何疑问、意见或请求，可通过以下方式与我们联系：
我们将在收到您的请求并验证身份后的 15 个工作日内予以答复。
Sichuan Yujia Rui Software Technology Co., Ltd. ("we", "us", or "our") recognizes the importance of your personal information and is committed to protecting it to the best of our ability. We adhere to the following principles when handling your personal information: accountability, purpose limitation, consent, data minimization, security, user participation, and transparency.
FuturePost Unlock is an encrypted time-capsule QR code tool. Our core design principle is that the content you enter and the encrypted QR codes you generate stay on your device, never pass through any server, and we have no way to access what you lock inside a capsule. Please read and fully understand this Privacy Policy before using FuturePost Unlock (the "App").
To provide the encrypted time-capsule and scan functionality, the App processes the following data on your device (this data stays on your device and is never sent anywhere):
| Data | Purpose | Storage Location |
|---|---|---|
| Text content you enter on the Create page | AES-256-GCM encryption and QR code generation; original text is purged from memory after encryption | Runtime memory only; not persisted |
| Generated QR code image (when saved to Photos) | Allows you to share the code with others or scan it on another device | Written to the system Photos library only when you actively tap "Save to Photos" |
| Scan result (briefly displayed after scanning) | Shows the original content after unlock | Runtime memory only; cleared when the page is closed |
| App preferences (e.g., interface language) | Storing your preferences | App preferences (UserDefaults) |
| Device system uptime information | Detects potential time manipulation to keep the countdown accurate | Used locally for verification only; not stored, not transmitted |
The App requests the following permissions only when you actively trigger the corresponding feature, and never in the background:
The information described above is used solely on your device, for the following purposes:
We do not use any of your information for advertising, profiling, marketing, or any purpose unrelated to the functions described above.
QR codes that you actively save to Photos and share with others are your own sharing behavior, for which you alone are responsible. The QR code itself is protected with AES-256-GCM; no third-party scanner can read its content before the unlock time.
futurecode://unlock private URL scheme, recognized and decrypted only by this App.All data processed by the App is stored locally on your device (runtime memory, Photos library, app preferences) and never passes through, nor is stored on, any of our servers. The original text you enter is purged from memory once the QR code is generated; the content shown after a scan unlock also lives only in runtime memory and is cleared when the page is closed. Uninstalling the App completely removes all local data produced by it.
To prevent users from unlocking early by adjusting the system clock, the App cross-references device system uptime for local verification. This check runs entirely offline on your device and collects or transmits no personally identifiable information.
You may exercise the following rights over your data at any time:
The App is not intended for users under 18 years of age and does not actively collect personal information from minors. If you are a minor, please use the App under the guidance of a guardian. Guardians should guide minors on appropriate use of the encryption and scan features, and ensure that no illegal or inappropriate content is placed inside a time capsule.
We may revise this Privacy Policy from time to time. If a material change occurs, we will notify you prominently within the App or on our official website. Your continued use of the App after an update constitutes your acceptance of the updated Policy.
If you have any questions, comments, or requests regarding this Privacy Policy or our data practices, please contact us:
We will respond within 15 business days after receiving your request and verifying your identity.
