Pro Video Downloader隱私權政策
Pro Video Downloader（以下稱「本擴充功能」）是一個在 Chrome 瀏覽器中偵測並下載網頁影片的工具。我們重視你的隱私，以下說明本擴充功能會處理哪些資料、如何處理。
重點摘要
- 影片與瀏覽資料只在你的電腦上處理，不會傳送給我們或任何第三方。
- 本擴充功能沒有任何分析、追蹤、廣告或遙測功能。
- 本擴充功能只會連線到影片本身所在的網站，就和你在網頁上播放該影片時一樣；唯一的例外是付費版的授權確認（見下方「付費版授權」）。
會處理哪些資料
| 資料 | 用途 | 存放位置與期限 |
|---|---|---|
| 網頁中影片的網址 | 列出可下載的影片 | 瀏覽器暫存空間；關閉分頁或關閉 Chrome 後清除 |
| 網頁標題、網址 | 作為預設檔名、標示影片來源 | 同上 |
| 影片播放時的請求標頭（例如 Referer、Cookie） | 下載時沿用相同的條件，讓網站正常提供影片 | 同上；只保存在記憶體中的暫存空間 |
| 影片預覽截圖、長度、解析度 | 在清單中顯示，方便辨識影片 | 同上 |
| 下載紀錄（檔名、進度、錯誤） | 顯示下載進度 | 同上 |
| 設定值 | 記住你的偏好 | 瀏覽器本機儲存空間，直到你恢復原廠設定或移除擴充功能 |
| 你選擇的儲存資料夾 | 將影片寫入該資料夾 | 瀏覽器本機儲存空間；本擴充功能只取得資料夾名稱，無法得知完整路徑 |
| 操作紀錄 | 協助排查問題 | 瀏覽器本機儲存空間，最多保留 500 筆；可在設定頁清除 |
操作紀錄寫入前會自動遮蔽敏感資訊：Cookie 只保留名稱、值改成 ***；認證標頭與網址中的 token、簽章等參數也會遮蔽。只有在你主動使用「複製問題報告」並自行傳送時，這些紀錄才會離開你的電腦。
付費版授權
如果你購買並啟用付費版，本擴充功能會將授權碼與產品編號傳送給授權服務 Gumroad（api.gumroad.com），用來確認授權是否有效，大約每 24 小時確認一次。Gumroad 會回傳授權狀態（例如訂閱是否有效、是否已退款）、啟用次數與購買時使用的電子郵件，這些資料只保存在你的瀏覽器中，用來顯示付費版狀態。
付款由 Gumroad 處理，本擴充功能不會接觸你的付款資料。Gumroad 如何處理你的資料，請參考其隱私權政策。
未啟用付費版時，本擴充功能不會連線到 Gumroad。免費版的每日下載次數只記錄在你的瀏覽器中。
不會做的事
- 不會把你的瀏覽資料或影片資料上傳到我們或第三方的伺服器。
- 不會販售、出租或分享你的資料。
- 不會讀取與影片無關的網頁內容用於其他目的。
- 不會在 YouTube 上運作（依 Chrome 線上應用程式商店政策）。
你可以做的事
- 在設定頁按「清除紀錄」刪除所有操作紀錄。
- 在設定頁按「恢復原廠設定」清除所有設定與所選資料夾。
- 在設定頁按「在此裝置停用」移除本機的付費版授權資料。
- 移除本擴充功能時，Chrome 會一併刪除它在瀏覽器中儲存的所有資料。

Privacy Policy
Pro Video Downloader (the "Extension") is a Chrome extension that detects and downloads videos on web pages. We care about your privacy. This policy explains what data the Extension handles and how.
Summary
- Video and browsing data is processed only on your computer and is never sent to us or any third party.
- The Extension has no analytics, tracking, advertising or telemetry.
- The Extension only connects to the website the video comes from, just as your browser does when you play the video. The only exception is the Premium license check (see "Premium license" below).
What data is handled
| Data | Purpose | Where it is stored and for how long |
|---|---|---|
| Addresses of videos on the page | To list the videos you can download | Temporary browser storage; cleared when you close the tab or Chrome |
| Page title and address | To suggest a file name and show where a video came from | Same as above |
| Request headers sent while the video plays (e.g. Referer, Cookie) | To download under the same conditions so the website serves the video normally | Same as above; kept only in in-memory temporary storage |
| Video preview images, duration, resolution | To show in the list so you can recognise videos | Same as above |
| Download records (file name, progress, errors) | To show download progress | Same as above |
| Settings | To remember your preferences | Local browser storage, until you reset to defaults or remove the Extension |
| The save folder you choose | To write videos to that folder | Local browser storage; the Extension only receives the folder's name, not its full path |
| Activity log | To help troubleshoot problems | Local browser storage, up to 500 entries; can be cleared in Settings |
Sensitive information is masked automatically before anything is written to the log: only cookie names are kept (values become ***), and authentication headers and tokens or signatures in addresses are masked too. The log only leaves your computer if you use "Copy problem report" and send it yourself.
Premium license
If you buy and activate Premium, the Extension sends your license key and the product ID to the licensing service Gumroad (api.gumroad.com) to check that the license is valid, about once every 24 hours. Gumroad returns the license status (for example whether the subscription is active or the purchase was refunded), the number of activations and the email address used for the purchase. This information is stored only in your browser and is used to show your Premium status.
Payments are handled by Gumroad; the Extension never sees your payment details. See Gumroad's privacy policy for how they handle your data.
If you have not activated Premium, the Extension does not connect to Gumroad. The free plan's daily download count is stored only in your browser.
What we do not do
- We do not upload your browsing or video data to our servers or anyone else's.
- We do not sell, rent or share your data.
- We do not read page content unrelated to videos for any other purpose.
- The Extension does not work on YouTube (in line with Chrome Web Store policy).
Your choices
- Click "Clear logs" in Settings to delete the activity log.
- Click "Reset to defaults" in Settings to clear all settings and the chosen folder.
- Click "Deactivate on this device" in Settings to remove the local Premium license data.
- When you remove the Extension, Chrome deletes all the data it stored in your browser.
