Privacy Policy
1. Who we are
DoMosaic (“the App”) is provided by Huazi (“we”, “us”). This policy describes how the App handles information when you use it on iOS.
Contact: support@huazi.com
2. On-device photo processing
When you import or capture photos, the App uses on-device frameworks (including Apple Vision) to detect faces, text, barcodes/QR codes, and certain private-information patterns, and to apply redaction styles you choose.
- Images selected for processing stay on your device.
- We do not operate a backend that receives, stores, or analyzes your photos.
- Detection, masking, and export pipelines do not upload image data.
3. Permissions
- Camera — used only if you take a photo inside the App for redaction.
- Photo Library (add) — used to save redacted images when you export.
- Photo picking uses system pickers so you can grant access only to selected images.
4. Metadata removal
By default, exported images have EXIF and GPS metadata stripped to reduce accidental leakage of location or device details.
5. Local settings and Pro data on device
Preferences (such as language), Pro feature settings, custom keyword rules, and saved templates/history may be stored locally on your device (for example via system storage APIs). This data is not uploaded as part of image processing.
6. Subscriptions and network use
Optional paid features (“DoMosaic Pro”) are offered through Apple In-App Purchase. Subscription status is validated with help from RevenueCat, which may process:
- Purchase history / subscription status (to unlock Pro)
- Anonymous or pseudonymous app user / device identifiers used for purchase restoration and entitlement sync
These network communications are separate from photo processing. No image content is sent to RevenueCat for detection or redaction.
Purchases are processed by Apple. We do not receive your full payment card details. See also Apple’s privacy information and RevenueCat’s privacy policy for their respective services.
7. Analytics, advertising, and tracking
The App does not include third-party advertising SDKs. We do not use App Tracking Transparency for cross-app advertising tracking. RevenueCat may collect limited technical data needed to operate subscriptions as described above.
8. Children
The App is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided information through the App, contact us and we will take appropriate steps.
9. Data retention
Photos you process remain under your control on device (and in your photo library if you save exports). Local App preferences remain until you delete the App or clear data. Subscription records are retained by Apple and RevenueCat according to their policies for as long as needed to provide purchases and support.
10. Your choices
- You can deny camera or photo-library permissions in iOS Settings; some features will be unavailable.
- You can delete the App to remove local App data on the device.
- You can manage or cancel subscriptions in your Apple ID subscription settings.
- You can restore purchases on a new device via the App’s restore control.
11. International users
Subscription validation may involve processing by service providers in other countries. Image redaction itself remains on-device.
12. Changes
We may update this policy as the App evolves. The “Last updated” date at the top will change when we do. Continued use after an update means you accept the revised policy.

隐私政策
1. 我们是谁
DoMosaic（“本应用”）由 Huazi（“我们”）提供。本政策说明你在 iOS 上使用本应用时，信息如何被处理。
联系邮箱：support@huazi.com
2. 本地照片处理
当你导入或拍摄照片时，本应用使用设备端能力（包括 Apple Vision）检测人脸、文字、条码/二维码及部分隐私信息模式，并按你选择的样式进行打码。
- 用于处理的图片保留在你的设备上。
- 我们不运营接收、存储或分析你照片的后端服务。
- 检测、打码与导出链路不会上传图片数据。
3. 系统权限
- 相机 — 仅在你于应用内拍摄待打码照片时使用。
- 相册（添加） — 在你导出时用于保存打码后的图片。
- 选图使用系统选择器，你可仅授权所选图片。
4. 元数据清除
默认情况下，导出图片会清除 EXIF 与 GPS 等元数据，以降低位置或设备信息被意外泄露的风险。
5. 设备本地的设置与 Pro 数据
语言等偏好、Pro 相关设置、自定义关键词规则、已保存的模板/历史等可能保存在你的设备本地（例如通过系统存储接口）。这些数据不会作为图片处理的一部分被上传。
6. 订阅与联网
可选付费功能（“DoMosaic Pro”）通过 Apple 应用内购买提供。订阅状态会借助 RevenueCat 校验，其可能处理：
- 购买记录 / 订阅状态（用于解锁 Pro）
- 用于恢复购买与权益同步的匿名或假名应用用户 / 设备标识
上述联网与图片处理相互独立。检测与打码不会向 RevenueCat 发送任何图片内容。
支付由 Apple 处理，我们不会获得你的完整银行卡信息。另请参阅 Apple 与 RevenueCat 各自的隐私说明。
7. 分析、广告与追踪
本应用不集成第三方广告 SDK，也不为跨应用广告追踪使用 App Tracking Transparency。RevenueCat 可能收集运营订阅所必需的有限技术数据（见上节）。
8. 儿童
本应用不以 13 岁以下儿童为对象。我们不会故意收集儿童的个人信息。若你认为儿童通过本应用提供了信息，请联系我们，我们会采取适当措施。
9. 数据保留
