In one sentence
PicEdit is a photo editor and batch tool that works entirely on your device. Your photos are never uploaded, the app does not transmit them over the network, and there are no accounts, ads, or analytics.
What we access, and why
| Data / permission | Purpose | Leaves the device |
|---|---|---|
Photos (READ_MEDIA_IMAGES, READ_EXTERNAL_STORAGE on Android 12 and below, READ_MEDIA_VISUAL_USER_SELECTED) | Show your photos in the in-app picker so you can select them, and display the selected items | No |
Location embedded in photos (ACCESS_MEDIA_LOCATION) | Read the GPS tags of the original file to display where a photo was taken, and keep or remove that location when you export, according to your choice | No |
| Other camera metadata (EXIF: model, lens, shutter, aperture, ISO, capture time, artist, copyright) | Displayed in the info panel; in batch tasks you may keep, strip, or rewrite it | No |
Writing to the gallery (WRITE_EXTERNAL_STORAGE on Android 9 and below) | Save results as a new file in Pictures/PicEdit (Download/PicEdit for formats the gallery does not index, such as ICO and ICNS) | No |
Your originals are never overwritten. Every result is a new file that you can delete from the system gallery at any time.
What we do not collect
- No device identifiers, advertising ID, IMEI, or MAC address
- No location tracking (the location inside a photo is only displayed locally; it is never uploaded and your location is never recorded)
- No usage analytics, crash reports, or interaction tracking
- No access to contacts, calendar, SMS, call logs, or microphone
- No accounts, no cloud sync, no third-party ad or analytics SDKs
Diagnostic logging
Only debug builds (not distributed to users) print EXIF details to the system log, so that issues such as “the gallery shows a location but the app cannot read it” can be diagnosed. Release builds print no photo metadata and write no log files.
Third-party components
PicEdit uses the following open-source components. All of them run locally and send nothing anywhere:
- AndroidX (Jetpack Compose, Core, Activity, Lifecycle)
- AndroidX ExifInterface (reading and writing EXIF)
- avif-coder (libavif / libaom, AVIF encoding)
Granting and revoking permissions
The system asks for photo and location permissions the first time you open the gallery. You can revoke them at any time in Settings → Apps → PicEdit → Permissions:
- Deny photo access: the app cannot list your library and can only open a single image through the system photo picker (in that case Android strips location metadata — that is Android’s privacy design)
- Deny location access: editing still works, but the info panel will not show where the photo was taken
Data retention and deletion
PicEdit stores nothing on any server. Locally there are only two kinds of data:
- Temporary cache files in the app’s private cache directory, cleaned up automatically when needed and removed when you uninstall the app
- Images you export, saved to your gallery or downloads folder, which you manage yourself
To delete them, remove the images from the system gallery, or clear the app’s data / uninstall the app.
Children’s privacy
PicEdit is not directed at children under 13 and does not knowingly collect information from them. Because the app collects no personal data at all, no children’s data is collected.
Changes to this policy
If this policy changes materially (for example, if a future version adds a feature that requires network access), we will update both this page and the release notes of the app update, and revise the effective date above. Continued use means you accept the updated policy.

一句话说明
PicEdit 是一款在你的手机本地完成图片编辑与批量处理的工具。照片不会上传到任何服务器，应用不联网传输你的照片，没有账号体系，也没有广告或统计。
我们访问哪些信息，用来做什么
| 信息 / 权限 | 用途 | 是否离开设备 |
|---|---|---|
照片与图片（READ_MEDIA_IMAGES、Android 13 之前的 READ_EXTERNAL_STORAGE、READ_MEDIA_VISUAL_USER_SELECTED） | 在应用内的相册页列出照片供你选择，并显示已选中的图片 | 否 |
照片中的拍摄位置（ACCESS_MEDIA_LOCATION） | 读取原图 EXIF 中的 GPS 信息，用于「图片信息」面板显示拍摄位置；导出时按你的选择保留或抹除定位 | 否 |
| 照片中的其他拍摄信息（EXIF：机型、镜头、快门、光圈、ISO、拍摄时间、作者、版权） | 在信息面板展示；批量任务中可选择保留、抹除或改写 | 否 |
写入相册目录（Android 9 及以下的 WRITE_EXTERNAL_STORAGE） | 把处理结果保存为新文件到 Pictures/PicEdit（应用不支持的格式如 ICO / ICNS 保存到 Download/PicEdit） | 否 |
原图不会被覆盖。 保存的是另存的新文件，你可以随时在系统相册中删除。
我们不收集什么
- 不收集设备标识符、广告 ID、IMEI、MAC 地址等设备信息
- 不收集你的位置（图片内嵌的定位只在本地显示，不会上传，也不会单独记录你的位置）
- 不收集应用使用统计、崩溃日志、点击行为
- 不读取联系人、日历、短信、通话记录、麦克风
- 没有账号、没有云端同步、没有第三方广告或分析 SDK
调试日志
仅调试版本（debug 包，不对外分发）在打开图片时会把 EXIF 信息输出到系统日志，便于开发排查「相册有定位但应用读不到」这类问题。正式版本不会输出任何照片信息，也不会写入日志文件。
第三方组件
PicEdit 使用了以下开源组件，它们均在本地运行，不会把你的数据发送到任何地方：
- AndroidX（Jetpack Compose、Core、Activity、Lifecycle）
- AndroidX ExifInterface（读取与写入 EXIF）
- avif-coder（libavif / libaom，用于 AVIF 编码）
权限的授予与撤回
首次使用相册功能时，系统会询问照片与定位相关权限。你可以随时在系统的「设置 → 应用 → PicEdit → 权限」中撤回：
- 拒绝照片权限：应用无法列出相册，只能通过系统照片选择器单张打开（这种情况下照片的定位信息会被系统抹除，属于 Android 的隐私设计）
- 拒绝定位权限：应用仍可正常编辑，只是信息面板不会显示拍摄位置
数据保留与删除
应用不在任何服务器上保存你的数据。本地仅有两类临时内容：
- 编辑过程中的缓存文件（位于应用私有缓存目录），应用会在必要时自动清理；卸载应用即全部清除
- 你主动导出的图片，保存在相册或下载目录，由你自行管理
如需删除上述内容：在系统相册中删除对应图片，或在系统设置中清除应用数据 / 卸载应用。
儿童隐私
PicEdit 不面向 13 岁以下儿童，也不会有意收集儿童的任何信息。由于应用本身不收集个人信息，不存在儿童数据被收集的情况。
政策变更
如果本政策发生实质变化（例如未来加入需要联网的功能），我们会在应用更新说明和本页面同时更新，并修改上方的生效日期。继续使用即表示你接受更新后的政策。
