OnceClean Duplicate Photos Privacy Policy

Last updated: October 8, 2026

Scope and purpose

This policy applies to OnceClean Duplicate Photos / 一次清重复照片清理 ("OnceClean"), a local-first iPhone and iPad utility that audits a photo library for duplicate, similar, burst, screenshot, blurry, and large-video candidates, lets you review the groups, and moves the photos you confirm through PhotoKit into the system Recently Deleted album. It describes what the app reads, what it stores on the device, and what it never does.

Photo library access

OnceClean asks for photo library access so it can read the assets you authorize it to audit, and for the PhotoKit permission that performs a deletion. The app does not request the camera, the microphone, contacts, location, or health data. You can change or revoke photo access at any time in iOS Settings; the app then simply has fewer photos to audit, and manual paths remain available.

What stays on your device

Photo fingerprints, similarity groups, your keep and skip decisions, filters, scan settings, the pending-deletion tray, and run history are written as local files on the device. The completion report is generated locally as well. OnceClean has no account system and no cloud sync, so none of this leaves the device through the app.

What OnceClean does not do

OnceClean does not upload photo content or thumbnails anywhere. It does not require an account, does not include third-party analytics, advertising, tracking, or crash-reporting SDKs, and does not use your photo library to build a profile. It also does not clean memory, scan for malware, or boost device speed, and it does not use scare messaging about system health.

No network required

Scanning, grouping, review, deletion, and the completion report work with the device offline. Natural-language filtering is parsed on the device, and when a phrase cannot be parsed the app falls back to visible filter chips instead of sending the text to a server. OnceClean has no server-side component of its own.

Purchases

The free version audits the full library and limits deletion to 50 photos per scan run. A single lifetime non-consumable purchase, com.feijiang2026.OnceClean.buyout.lifetime, unlocks unlimited deletion, recommended batch processing, natural-language filtering, and incremental scanning. There is no subscription. Apple processes the payment, the receipt, refunds, and purchase restoration; OnceClean only reads the transaction state that StoreKit reports on the device. Restore purchases is available in the app.

Deletion, retention, and your controls

Deleting a photo in OnceClean hands the confirmed assets to PhotoKit, which moves them to iOS Recently Deleted; the recovery window is managed by the system, not by the app. Local app data such as fingerprints, decisions, tray state, and run history can be cleared from inside the app, and uninstalling OnceClean removes its local data. Photos in your library are never modified by any other path.

Children

OnceClean is a general-purpose utility for cleaning up a photo library. It is not directed to children, offers no social features, chat, or public user content, and does not knowingly collect personal information from children.

Security

OnceClean relies on iOS app sandboxing and on-device storage protection. No storage method is perfect, so the app does not promise absolute security; keeping your device passcode and iOS updates current is the most effective protection for the local data involved.

Changes to this policy

If the app's data behavior changes, this page is updated before that change ships, and the date above reflects the latest revision. Continued use after an update means you accept the revised policy.

一次清重复照片清理 隐私政策

最后更新：2026 年 10 月 8 日

适用范围与用途

本政策适用于「一次清重复照片清理」（OnceClean Duplicate Photos，下称「一次清」）。它是一款本地优先的 iPhone 与 iPad 工具：在本机扫描照片库，找出重复、相似、连拍、截图、模糊和大视频候选，让你逐组复核，并把确认删除的照片交给 PhotoKit 送进系统「最近删除」。本政策说明它读取什么、在本机保存什么，以及它绝不会做什么。

照片库权限

一次清会请求照片库访问权限，用于读取你授权审计的照片，并请求 PhotoKit 的删除权限来完成你确认的删除。它不申请相机、麦克风、通讯录、定位或健康数据。你可以随时在 iOS「设置」中修改或收回照片权限；收回后 App 只是可审计的照片更少，手动流程仍然可用。

只保存在本机的内容

照片指纹、相似分组、你的保留与跳过决定、筛选条件、扫描设置、待删托盘和运行历史都以本地文件形式写在设备上，完成报告也在本机生成。一次清没有账号体系，也没有云同步，这些内容不会通过 App 离开设备。

一次清不会做的事

一次清不会把照片内容或缩略图上传到任何地方；不需要注册账号；不包含第三方分析、广告、跟踪或崩溃收集 SDK；也不会用你的照片库建立画像。它不做内存清理、不做病毒扫描、不做系统加速，也不会用「系统危急」之类的话术吓人。

没有网络也能用

扫描、分组、复核、删除和完成报告在设备离线时照常工作。自然语言筛选在本机解析；解析不了时，App 会退回可见的筛选标签，而不是把文字发送到服务器。一次清没有自己的服务端组件。

购买

免费版本可以审计整个照片库，每次扫描最多删除 50 张。一次买断（非消耗型，产品标识 com.feijiang2026.OnceClean.buyout.lifetime）解锁不限量删除、推荐批量处理、自然语言筛选和增量扫描，没有订阅。付款、收据、退款和购买恢复均由 Apple 处理；一次清只读取 StoreKit 在设备上返回的交易状态，App 内提供「恢复购买」。

删除、保留与你的控制权

在一次清里删除照片时，确认过的素材会交给 PhotoKit 移入 iOS「最近删除」，恢复窗口由系统而不是由 App 管理。App 内的本地数据（指纹、决定、托盘状态、运行历史）可以在 App 内清除，卸载一次清也会移除这些本地数据。照片库中的照片不会经由其它任何路径被修改。

儿童

一次清是面向一般用户的照片库整理工具。它不面向儿童，没有社交、聊天或公开的用户内容功能，也不会在知情情况下收集儿童的个人信息。

安全

一次清依赖 iOS 的应用沙盒和本地存储保护。没有任何存储方式绝对安全，因此 App 不承诺绝对安全；保持设备密码和 iOS 更新是保护相关本地数据最有效的方式。

政策变更

如果 App 的数据行为发生变化，本页面会在该变化发布前更新，页面顶部的日期即最新修订时间。更新后继续使用表示你接受修订后的政策。
