|
|
<ol class="support-steps">
|
|
<li>Install KoalaSync from the official Chrome, Firefox, or Edge store. Pin the KoalaSync icon to the browser toolbar if you want quicker access.</li>
|
|
<li>Each person needs KoalaSync in their own supported desktop browser and their own access to the video website.</li>
|
|
<li>Open the extension once. The short tutorial points to the <strong>Room</strong>, <strong>Sync</strong>, and <strong>Settings</strong> tabs; you can restart it later under <strong>Settings → Troubleshooting</strong>.</li>
|
|
<li>Choose a recognizable username under <strong>Settings → Profile & Appearance</strong>. It is shown to the other people in the room.</li>
|
|
<li>Open the video website. If the browser asks whether KoalaSync may access it, allow access for that site and reload the page.</li>
|
|
</ol>
|
|
<p>KoalaSync does not provide or stream the video. Everyone opens the same content locally, and KoalaSync coordinates playback controls.</p>

<li>Open KoalaSync and select <strong>Room</strong>.</li>
|
|
<li>Click <strong>Create New Room</strong>. By default, KoalaSync copies the new invite link to your clipboard.</li>
|
|
<li>Share the complete invite link only with the intended participants. The part after <code>#</code> contains the room credentials and the secret needed for encrypted chat.</li>
|
|
<li>After joining, use the participant list to confirm who is connected.</li>
|
|
</ol>
|
|
<h3>Join</h3>
|
|
<p>Open the invite in the same desktop browser profile where KoalaSync is installed. The join page passes the room settings to the extension. You can also use <strong>Manual Connect / Advanced</strong> to enter a room ID and optional password, or select a public room, but manual and legacy joins do not provide the current chat secret.</p>
|

<p>Room credentials remain available locally until you leave or replace the room. Click <strong>Leave Room</strong> when you are finished.</p>

<p>When room control is open to everyone, actions on the selected player and the popup's <strong>Play</strong> and <strong>Pause</strong> buttons are sent to the room. The <strong>Last Activity Status</strong> shows the most recent room action.</p>
|
|
<ul>
|
|
<li><strong>Jump to Others:</strong> moves your selected video to the known time reported by other participants. It requires another participant with a usable playback time.</li>
|
|
<li><strong>Jump to Me:</strong> uses your selected video's current time as the target and moves the room to you.</li>
|
|
<li><strong>Sync:</strong> runs the selected Force Sync mode as a coordinated room action. Use it when normal play, pause, or seeking left someone behind.</li>
|

<p>Force Sync cannot fix different videos, missing website access, an unloaded player, or a site that blocks the required playback action. Check that everyone selected the intended content first.</p>

<h2 id="episode-sync-title">Use Auto-Sync Next Episode</h2>
|
|
<p><strong>Auto-Sync Next Episode</strong> is enabled by default under <strong>Settings → Playback & Sync</strong>. On supported sites, KoalaSync detects a recognizable episode change, pauses, and opens an <strong>Episode Lobby</strong> while participants load the same episode. Playback starts together when the lobby is ready.</p>
|
|
<ul>
|
|
<li>Use <strong>Skip & Play anyway</strong> if you do not want to wait.</li>
|
|
<li>A timeout or participants leaving can cancel the lobby; use manual selection and Force Sync afterward.</li>
|
|
<li>The feature depends on usable episode titles. It is not available for ordinary single videos, and some services expose too little episode information.</li>
|
|
<li>Choosing <strong>Do not send</strong> for media titles prevents creation of an episode lobby. <strong>Send episode ID</strong> can preserve episode matching without sharing the full media title when an episode ID is detectable.</li>

<h2 id="room-chat-title">Chat does not work, or one person cannot see it</h2>
|
|
<p>Room chat was introduced in KoalaSync 3.0.0. Every participant who wants to send or read chat messages needs version 3.0.0 or newer. Older versions can still join a room and synchronize playback, but they do not support room chat.</p>
|
|
<ol class="support-steps">
|
|
<li>Update KoalaSync in every browser. Open the extension and check the version in the top-right corner. Each participant needs version <strong>3.0.0 or newer</strong>.</li>
|
|
<li>After updating, the room creator should leave the old room and click <strong>Create New Room</strong>. This creates a new chat encryption secret and includes it in the new invite link.</li>
|
|
<li>Send that newly copied invite link to your friends. Each friend must leave the old room and join through the link so their extension receives the same chat encryption secret.</li>
|
|
<li>Do not join by typing only the room ID and password, and do not reuse an old invite link beginning with <code>#join:</code>. Both can connect playback synchronization, but neither contains the chat secret.</li>
|
|
<li>Each participant must select their local video tab, then open <strong>Settings → Room Chat</strong> and turn on <strong>Enable Room Chat</strong>. The chat appears on the selected video page, not inside the extension popup.</li>

|

<p>Open <strong>Settings → Privacy</strong>. Tab titles and media titles have separate controls:</p>
|

<ul>
|
|
<li><strong>Send tab title:</strong> shares or withholds the title shown by the selected browser tab.</li>
|
|
<li><strong>Send full title:</strong> shares the media title detected from the player.</li>
|
|
<li><strong>Send episode ID:</strong> shares only a detected identifier such as <code>S01E04</code>. If no episode ID can be detected, no useful full title is substituted.</li>
|
|
<li><strong>Do not send:</strong> withholds the media title.</li>
|
|
</ul>
|
|
<p>Reducing title sharing can make automatic tab matching and episode coordination less informative. Disabling media-title sharing also prevents Auto-Sync Next Episode from creating a lobby.</p>

|
|
<li>The operator of a custom relay controls its hosting, logging, retention, updates, and availability. The official relay's privacy policy does not describe third-party instances.</li>
|

<li>If the custom URL is rejected or the connection fails, confirm the complete WebSocket URL with its operator. A normal website URL is not always the relay URL.</li>

<span class="support-eyebrow">Privacy & permissions</span>
|
|
<h2 id="permissions-title">Why does the browser show such a broad warning?</h2>
|
|
<p>Browsers may say that KoalaSync can “read and change all your data on all websites.” The wording is broad because KoalaSync is designed to work with video players across many different websites instead of a short fixed list.</p>
|
|
<p>KoalaSync injects its synchronization script into the video tab you actively select. On that tab it needs to find and control the video element, synchronize play, pause, and seeking, and display the optional room chat overlay. Open tab titles are read to populate the tab selector. KoalaSync does not create a general browsing or watch history.</p>

<span class="support-eyebrow">Privacy</span>
|
|
<h2 id="data-handling-title">What data leaves my browser?</h2>
|
|
<p>KoalaSync only connects to a relay while you are actively in a room. During that session, the relay temporarily processes the data required to connect participants and synchronize playback.</p>
|
|
<ul>
|
|
<li><strong>Room and presence:</strong> room ID, peer ID, display name, connection state, and the information needed to join the room.</li>
|
|
<li><strong>Playback synchronization:</strong> actions and state such as play, pause, seeking, and the current playback position.</li>
|
|
<li><strong>Titles:</strong> tab or media titles may be shared with room participants depending on your title privacy settings. They can be limited or disabled.</li>
|
|
<li><strong>Room chat:</strong> message text is encrypted in the extension before transmission. The relay receives ciphertext and delivery metadata, but not the chat secret or readable message text.</li>
|
|
<li><strong>Stored locally:</strong> preferences, current room credentials, and the chat secret are stored in the browser. The chat secret is not sent to the relay. Decrypted chat entries remain only in the current page overlay and are not written to browser storage.</li>
|
|
<li><strong>Operational logs:</strong> the relay may log technical connection and security information such as IP addresses, protocol versions, socket or peer identifiers, and shortened room identifiers. Retention depends on the server infrastructure and configuration.</li>
|
|
</ul>
|
|
<p>KoalaSync does not create a persistent browsing, room, synchronization, chat, or watch history. Browser or operating-system notifications may retain notification text according to their own settings.</p>

<h2 id="trust-title">Why should I trust KoalaSync?</h2>
|
|
<p>Trust should not depend on promises alone. The KoalaSync browser extension, relay server, build scripts, release workflow, and Dockerfile used for official GitHub releases are public under the MIT License.</p>
|
|
<p>Official extension ZIPs on GitHub Releases and Docker images on GitHub Container Registry are built by the public GitHub Actions release workflow. Signed SLSA provenance attestations connect each artifact's exact digest to this repository, its release tag and commit, and the workflow that built it.</p>
|
|
<p>You can install KoalaSync from an official browser store, download the Chrome or Firefox ZIP from GitHub Releases, build the extension yourself, or run your own relay server. Manual ZIP installation uses your browser's developer or manual extension installation process.</p>

<strong>What an attestation proves, and what it does not.</strong>
|
|
<p>An attestation proves the origin and build workflow of the GitHub release ZIP or GHCR image with that exact digest. It does not guarantee that software has no bugs or vulnerabilities. It also does not by itself prove that a package downloaded from a browser store is byte-for-byte identical to a GitHub release ZIP.</p>
