常見問題FAQ

來自使用者最常問的問題The questions we hear most often

照片會被上傳嗎?開發者看得到我的照片嗎?Are my photos uploaded? Can the developer see them?

看不到,因為照片根本不會上傳。光影傳承是「本地優先」設計:掃描、AI 辨識、裁切全部在你的手機上完成,不需要註冊帳號,也沒有雲端同步,照片只存在你自己的裝置裡。 No — because they are never uploaded in the first place. Photo Legacy is local‑first: scanning, AI detection, and cropping all run on your phone. There is no account and no cloud sync; your photos exist only on your device.

唯一的例外是設定裡的「協助改善 AI」,預設是關閉的。你若主動打開,App 才會上傳相簿頁面的掃描圖和偵測框,用來改善自動裁切模型。這部分資料不會附帶姓名、Email 或任何帳號資訊,裁切出來的個別照片也不會上傳,而且隨時可以關掉。 The only exception is the "Help improve AI" toggle in Settings, which is off by default. If you choose to turn it on, the app uploads album‑page scans and detection boxes to improve the cropping model. This data carries no name, email, or account info, individual cropped photos are never uploaded, and you can switch it off anytime.

會收集我的個資嗎?Do you collect personal data?

不收。App 不用註冊、沒有帳號,照片和掃描結果都只存在你自己的手機裡。詳細說明請見隱私政策 No. There is no sign‑up and no account; photos and scan results live only on your phone. See the Privacy Policy for details.

全程離線,換手機時資料怎麼辦?Everything is offline — what happens when I switch phones?

iPhone 換 iPhone:用內建的手機轉移(快速開始),或從 iCloud/電腦備份還原,App 連同裡面所有相簿會原封不動搬過去,什麼都不用做。 iPhone to iPhone: use the built‑in phone transfer (Quick Start) or restore from an iCloud / computer backup — the app and all its albums move over intact, nothing extra needed.

Android 換機或跨平台:換機前先進相簿,右上角選單按「全部儲存」,掃描好的照片會存進系統相簿,跟你其他照片一起用原本習慣的方式(Google 相簿、換機工具等)搬到新手機。 Android or cross‑platform: before switching, open an album and tap "Save All" in the top‑right menu. Your scanned photos are saved into the system gallery and migrate with the rest of your photos (Google Photos, transfer tools, etc.).

另外每張照片隨時都能單張儲存或分享出去,資料是你的,不會被綁在 App 裡。 Every photo can also be saved or shared individually at any time — your data is yours, never locked in the app.

之前拍好的老照片已經在手機相簿裡,可以直接匯入嗎?I already photographed old photos — can I import them?

可以!進入任一本相簿,右上角選單選「匯入相簿頁面」,就能從手機相簿一次選多張匯入,App 會自動偵測、裁切、擺正,跟現場掃描一樣。之前拍好的相簿頁面或老照片直接匯入就好,不用再拍一次。 Yes! Open any album and choose "Import Album Page" from the top‑right menu. Pick multiple photos from your gallery at once — the app detects, crops, and straightens them exactly like a live scan. No need to re‑photograph anything.

手機內建的文件模式不是也會自動擺正嗎?Doesn't my phone's document mode already straighten scans?

文件模式適合掃「一張紙」:把整頁當成一份文件擺正。相簿的麻煩在於一頁上貼了好幾張照片:光影傳承會把頁面上的每張照片分別抓出來、個別裁切、個別擺正,一頁拍一次就變成好幾張獨立的照片檔,這是文件模式做不到的。 Document mode scans "one sheet of paper" and straightens the whole page as a single document. An album page holds several photos at once — Photo Legacy detects each photo on the page and crops and straightens them individually, turning one shot into multiple separate photo files. Document mode can't do that.

跟 Google 的照片掃描 App 有什麼不同?How is this different from Google's photo scanning app?

Google 的 PhotoScan 也不錯,不過它一次掃一張照片;光影傳承是一次拍整頁相簿,AI 自動把每張照片分開裁好,要掃整本幾百張的話會快很多。兩個其實可以互補。 Google's PhotoScan is a fine tool, but it scans one photo at a time. Photo Legacy captures a whole album page and the AI splits out every photo automatically — much faster when digitizing entire albums with hundreds of photos. The two can complement each other.

App 是免費的嗎?Is the app free?

目前完全免費。付費版推出之前安裝的裝置,日後的 Pro 功能永久免費,這是我們對早期支持者的感謝。 Completely free right now. Any device that installs before the paid tier ships gets Pro free for life — our thank‑you to early supporters.

我開過「協助改善 AI」,想刪除已上傳的資料怎麼辦?I enabled "Help improve AI" — how do I delete uploaded data?

寄信到 service@unityroot.org,我們會協助處理。也可以隨時在設定裡關閉開關,停止之後的上傳。 Email service@unityroot.org and we'll help. You can also switch the toggle off anytime to stop future uploads.
