Privacy Policy – iPhone & iPad
Effective date: October 27, 2026 · Applies to all versions of Resizia for iPhone and iPad (app identifier com.pengyao.resizia)
Overview
Resizia (“the app”) is developed by PENGYAO to resize images and compress file sizes on your device. The app is free and has no in-app purchases or ads. The app does not collect, store, upload, sell or share any personal data.
Data the app handles
- Images you choose are read and processed only on your device. Results are kept in the app’s temporary folder and are never uploaded to any server.
- App settings (appearance, Night mode, interface language, Elder mode, your remembered processing settings including the crop ratio, saved sizes, and “My modes” – up to 20, with the names you give them and their settings) are stored only on your device (UserDefaults). They never contain photos.
- Smart crop: when Smart crop is on, the app uses Apple’s Vision framework on your device to find the main subject or a face in the photo, only to place the crop frame. Detection works offline; results are not stored, uploaded or used to identify anyone.
- Photo info (EXIF / location): photos often contain hidden data such as GPS location, device model and capture time. “Remove photo info (location, etc.)” is on by default, and then output images contain none of it. If you turn it off, the original capture info and location are kept in the output. This happens entirely on your device; we never see or receive this data.
- Share extension (“Add to Resizia”): when you share images to Resizia from Photos or another app, the extension accepts images only and copies them (up to 9) into the app’s on-device shared container (App Group). When you open the app, they are moved into its temporary folder and deleted from the container. When you use “Open in” from Files or a chat app, the system copies the image into the app’s sandbox, and the copy is deleted after import. No network is used.
What we do not do
- No accounts or sign-in, and no personal information is requested.
- No analytics, advertising or third-party SDKs.
- No tracking and no use of the advertising identifier (IDFA).
- The app’s features work offline; no data is sent to us or to any third party. The only web links in the app (this policy and the support website) open in your browser when you tap them.
Permissions
- Photos (Add Only): requested only when you tap “Save to Photos”, to add the result to your Photos library. The app cannot read the photos already in your library.
- Choosing images uses the system photo picker, the Files app or the share extension; the app can access only the images you select (up to 9 for batch processing), without full library access.
You can change or revoke this permission at any time in Settings › Privacy & Security › Photos.
Data retention and deletion
No data is kept on any server. Temporary files on your device are managed by the system; deleting the app removes all of its local data, including settings.
Third parties
No data is shared with third parties. When you choose to Share an image, it is handed to the app you pick, whose own privacy policy applies. If you email us, your address is used only to reply to you.
Children
The app does not collect personal information from anyone, including children.
Changes
If this policy changes, the updated version will be posted at https://resizia.pengyaostudio.cn/privacy.html and in the app, with a new effective date.

概述
Resizia（以下简称“本应用”）由 PENGYAO 开发，用于在本机调整图片尺寸和压缩文件大小。本应用免费，无 App 内购买、无广告。本应用不收集、不存储、不上传、不出售也不分享任何个人数据。
我们处理的数据
- 你选择的图片：仅在你的设备上读取和处理，处理结果保存在设备的临时目录中；不会上传到任何服务器。
- 应用设置：外观、夜间模式、界面语言、长辈模式、记住的上次处理设置（含裁剪比例）、保存的尺寸，以及“我的模式”（最多 20 个，包括你起的名字和处理参数），都只保存在设备本地（UserDefaults）。这些设置不包含任何照片。
- 智能裁剪：开启“智能裁剪”后，本应用使用 Apple 的 Vision 框架在你的设备上识别画面主体或人脸，只用来决定裁剪框的位置。识别不联网，识别结果不保存、不上传，也不用于识别身份。
- 照片信息（EXIF / 位置）：照片里常带有 GPS 位置、设备型号、拍摄时间等信息。“去除照片信息（位置等）”默认开启，此时输出的图片不含这些信息；关闭后，原图的拍摄信息和位置会保留在输出图片中。这一处理全部在本机完成，我们读不到也收不到这些信息。
- 分享扩展（“添加到 Resizia”）：你在“照片”等 App 中把图片分享到 Resizia 时，扩展只接收图片，并把图片（最多 9 张）复制到本应用在设备上的共享容器（App Group），打开 App 后立即移入 App 的临时目录，并从共享容器中删除。在“文件”或聊天 App 中选择“用其他应用打开”时，系统把图片复制到本应用的沙盒中，导入后删除副本。整个过程不联网。
我们不做的事
- 无账号、无登录，不要求填写任何个人信息。
- 不包含任何统计分析、广告或第三方 SDK。
- 不追踪你，也不使用广告标识符（IDFA）。

权限说明
- 照片（仅添加）：只在你点击“保存到相册”时请求，用于把处理结果存入“照片”。本应用无法读取你相册中已有的照片。
- 选择图片：使用系统照片选择器、“文件”或分享扩展，只能访问你主动选中的图片（批量处理最多 9 张），无需完整相册访问权限。
你可以随时在“设置 › 隐私与安全性 › 照片”中更改或撤销权限。
数据保留与删除
本应用不在服务器上保存任何数据。设备上的临时文件由系统管理，删除本应用即会清除本应用的全部本地数据（包括设置）。
第三方
本应用不与任何第三方共享数据。当你主动使用“分享”时，图片会交给你选择的目标应用，由该应用的隐私政策约束。通过邮件联系我们时，我们只会用你的邮件地址回复你的问题。
儿童隐私
