Privacy Policy — Instagram Reels Progress Bar

Last updated: 2026-08-29

The short version

This extension does not collect, store, transmit, or sell any personal data. There is no analytics, no telemetry, no tracking, and no server. Nothing ever leaves your browser.

What the extension does

Instagram Reels Progress Bar draws a draggable seek bar over videos on instagram.com so you can jump to any point in a video. It reads the current playback position and duration of the video element on the page in order to draw the bar, and it writes a new playback position when you drag or click it. That is the entire interaction with the page.

What is stored

The extension stores exactly four appearance preferences using the browser’s extension storage API:

Setting Values
Bar thickness a number between 2 and 8
Handle size a number between 8 and 20
Hover area height a number between 8 and 32
Show time label true or false

Your browser keeps these in your own profile. If you have browser sync turned on, your browser vendor syncs them between your own devices the same way it syncs your bookmarks. They are never sent to the developer or to any third party. Uninstalling the extension removes them.

What is not collected

Permissions

Permission Why
storage To remember the four appearance settings above.
Host access to instagram.com The extension needs to run on Instagram pages to find the video element and draw the seek bar over it. It runs on no other website.

Network activity

The extension makes no network requests of its own. It bundles no remote code and loads nothing from external servers.

Changes

If this policy ever changes, the updated version will be published at this same address and the date above will be updated.

隱私權政策 — Instagram Reels Progress Bar

最後更新:2026-08-29

一句話版本

這個擴充功能不蒐集、不儲存、不傳送、不販售任何個人資料。沒有分析工具、沒有遙測、沒有追蹤、沒有伺服器。所有東西都留在你的瀏覽器裡。

這個擴充功能做什麼

Instagram Reels Progress Bar 在 instagram.com 的影片上畫一條可拖曳的進度條,讓你跳到影片的任意位置。它會讀取頁面上影片元素的目前播放位置與總長度來畫這條進度條,並在你拖曳或點擊時寫入新的播放位置。與頁面的互動僅止於此。

儲存了什麼

擴充功能使用瀏覽器的擴充功能儲存 API 儲存四項外觀設定:

設定 可能的值
進度條粗細 2 到 8 之間的數字
拖曳圓點大小 8 到 20 之間的數字
感應區高度 8 到 32 之間的數字
顯示時間標籤 truefalse

這些資料由瀏覽器存在你自己的設定檔中;若你開啟了瀏覽器同步功能,瀏覽器廠商會在你自己的裝置之間同步它們,就像同步書籤那樣。這些資料不會傳送給開發者或任何第三方。移除擴充功能即會一併移除。

沒有蒐集什麼

權限說明

權限 用途
storage 記住上述四項外觀設定。
instagram.com 的網站存取權 擴充功能需要在 Instagram 頁面上執行,才能找到影片元素並把進度條畫上去。它不會在其他任何網站執行。

網路行為

政策變更

若本政策有所變更,更新後的版本會發布在同一個網址,並更新上方的日期。
