PhotoSync

隐私政策

生效日期: 2026 年 9 月 17 日

PhotoSync 帮助你把手机里的照片和视频备份到自己的电脑, 或备份到你自己的 WebDAV / NAS / 云盘 (Google Drive、Dropbox、OneDrive)。我们高度重视你的隐私, 本 App 的设计原则是: 数据只在你自己的设备和你自己的存储之间流动, 不经过我们。

我们不收集任何个人信息

PhotoSync 不收集、不存储你的照片或个人信息。我们没有服务器保存你的数据, 也不使用任何第三方分析、广告或内购 SDK。

唯一涉及外部的是内购付款, 见下方"App 内购买"一节 —— 它由 Apple 直接处理, 只涉及购买状态, 不涉及你的照片。

你的照片如何传输

备份到电脑: 照片和视频仅在你的手机和你自己的电脑之间, 通过同一 Wi-Fi 下的本地网络直接传输, 不经过任何服务器。

浏览器传输: 手机在局域网内临时开启一个网页服务, 供你在同一网络下的电脑用浏览器访问。该服务需要配对码才能访问, 只在你开启期间运行, 退出 App 即关闭。数据同样只在你的两台设备之间流动。

WebDAV 备份 (可选功能)

如果你主动配置 WebDAV, 照片会从你的手机直接上传到你本人的 NAS 或 WebDAV 存储, 不经过我们的服务器, 我们也不做任何中转或留存。

  • 这是可选的: 不配置 WebDAV, 电脑备份和浏览器传输完全可用。
  • 账号密码只存在你的手机上: 保存在设备的系统安全存储 (iOS Keychain) 中, 不会上传。
  • 断开不会删除已上传的照片: 那些文件在你自己的存储里, 由你自行管理。

云盘备份 (可选功能, 测试中)

你也可以把照片备份到自己的 Google Drive、Dropbox 或 OneDrive 账号。上传从你的手机直连到你本人账号的云端, 不经过我们的服务器。该功能目前仍在测试，尚不稳定，后续可能调整或下线；已上传的文件保存在你自己的云盘里，不受影响。

  • 授权方式: 通过各家的官方登录页完成授权, 我们拿不到也存不下你的云盘密码; 只保留一枚可随时在云盘后台撤销的访问令牌, 存在设备的系统安全存储 (iOS Keychain) 中。
  • 最小权限: 只申请写入本 App 专属文件夹所需的权限 (Google Drive 使用 drive.file), 读不到你网盘里的其他内容。
  • 断开不会删除已上传的照片: 那些文件在你自己的云盘里, 由你自行管理。

App 内购买

iPhone / iPad 版的部分功能通过 App 内购买提供。付款由 Apple App Store 处理, 我们接触不到你的支付信息。

购买状态由 Apple 的 StoreKit 直接返回给 App, 我们不使用任何第三方内购服务 —— 购买凭证不经过我们的服务器, 也不提供给任何第三方。

App 使用的权限

  • 照片库访问: 仅用于读取你选择备份的照片和视频; 使用"浏览器传输"上传时, 用于把文件写入你指定的相册。
  • 本地网络: 仅用于在局域网内发现你的电脑并与之传输文件。
  • 网络访问: 仅在你启用 WebDAV 或云盘备份时, 用于连接你填写的服务器或你授权的云盘。

数据存储

备份到电脑的文件保存在你电脑上由你自己指定的文件夹中; 备份到 WebDAV 或云盘的文件保存在你本人的存储中。都完全由你掌控, 开发者无法访问。

儿童隐私

本 App 不面向 13 岁以下儿童, 也不会有意收集任何儿童的个人信息。

政策变更

如本隐私政策有更新, 我们会在此页面发布最新版本并更新生效日期。

Privacy Policy

Effective date: September 17, 2026

PhotoSync helps you back up the photos and videos on your phone to your own computer, or to your own WebDAV / NAS / cloud drive (Google Drive, Dropbox, OneDrive). We take your privacy seriously, and the app is built on one principle: your data moves only between your own devices and your own storage — never through us.

We do not collect any personal information

PhotoSync does not collect or store your photos or personal information. We have no servers that hold your data, and we do not use any third-party analytics, advertising or in-app purchase SDKs.

The only outside party involved is payment, see "In-app purchases" below. It is handled entirely by Apple, and it concerns purchase status only, never your photos.

How your photos are transferred

Backup to your computer: photos and videos are transferred only between your phone and your own computer, directly over the local network on the same Wi-Fi. This data never passes through any server.

Browser transfer: your phone temporarily runs a web service on your local network so you can open it from a computer on the same network. It requires a pairing code, runs only while you have it switched on, and stops when you quit the app. The data still moves only between your two devices.

WebDAV backup (optional)

If you configure WebDAV, your photos are uploaded directly from your phone to your own NAS or WebDAV storage. They do not pass through our servers, and we neither relay nor retain them.

  • It is optional: computer backup and browser transfer work without WebDAV.
  • Credentials stay on your phone: they are kept in the device's secure storage (iOS Keychain) and are never uploaded.
  • Disconnecting does not delete uploaded photos: those files live in your own storage and remain yours to manage.

Cloud drive backup (optional, in testing)

You can also back up to your own Google Drive, Dropbox or OneDrive account. Uploads go directly from your phone to the cloud storage in your own account, never through our servers. This feature is still in testing and not yet stable; it may change or be discontinued. Files already uploaded stay in your own cloud drive and are unaffected.

  • How you authorize: you sign in on each provider's own official page. We never receive or store your cloud drive password — we keep only an access token you can revoke at any time from your provider's settings, stored in the device's secure storage (iOS Keychain).
  • Minimum scope: we request only what is needed to write into this app's own folder (Google Drive uses drive.file). We cannot read anything else in your drive.
  • Disconnecting does not delete uploaded photos: those files live in your own cloud storage and remain yours to manage.

In-app purchases

Some features of the iPhone / iPad app are offered through in-app purchase. Payment is handled entirely by the Apple App Store; we never see your payment details.

Purchase status comes straight from Apple's StoreKit. We do not use any third-party in-app purchase service — your purchase receipt never passes through our servers, and is not given to any third party.

Permissions the app uses

  • Photo library access: used only to read the photos and videos you choose to back up, and — when you upload via Browser transfer — to write files into the album you pick.
  • Local network: used only to discover your computer on the LAN and transfer files to it.
  • Internet access: used only when you enable WebDAV or cloud drive backup, to reach the server you entered or the cloud drive you authorized.

Data storage

Files backed up to your computer are saved to a folder you choose; files backed up over WebDAV or to a cloud drive are saved in your own storage. Either way they remain fully under your control, and the developer cannot access them.

Children's privacy

This app is not directed to children under 13, and we do not knowingly collect any personal information from children.

Changes to this policy

If this privacy policy changes, we will post the updated version on this page and revise the effective date.
