Overview

Gemini サイドバーの会話履歴を個別に非表示。拡張アイコンでプレビュー復元も可能。

🟢 企業向け Gemini でチャット履歴を UI 上だけ非表示に。削除不可の環境でも安全に運用。 【概要】 Gemini のサイドバーに並ぶチャット履歴を、行ごとに「×」で個別に非表示にできる拡張機能です。ツールバーアイコンで ON(非表示有効)/OFF(プレビュー) を切り替え、プレビュー中は一時的に全件表示+個別の「↩(復元)」が行えます。 サーバー上のデータは変更しません(UI 上の不可視化のみ)。履歴データの削除・送信は一切行いません。 【主な機能】 ・会話行の「×」で個別非表示(display:none) ・ツールバーアイコンで ON/OFF 切替(OFF=プレビュー) ・プレビュー時のみ表示される「↩(復元)」で非表示を解除 ・ローカル保存により、再読み込み後も状態を保持 ・サイドナビの開閉に依存せず動作(開いたままでも中身だけ隠す) 【使い方】 1.拡張をインストールし、ツールバーにピン留め 2.Gemini(https://gemini.google.com/)を開く 3.サイドバーの各会話行で「×」→ その行が非表示に 4.ツールバーアイコンをクリック → プレビュー(全件表示)、隠した行に「↩(復元)」 5.もう一度アイコンをクリック → ON に戻り、隠した行は再び非表示 【権限とデータ取り扱い】 ・使用権限:storage(状態の保持に使用) ・ホスト範囲:https://gemini.google.com/* ・保存内容:非表示にした会話の識別子と ON/OFF 設定(端末内のみ) ・外部送信なし/個人情報の収集なし/リモートコードなし 【よくある質問】 Q. サーバー上の履歴は削除されますか? A. いいえ。UI 上の非表示のみで、サーバーの会話データには触れません。 Q. 英語 UI やダークモードでも動きますか? A. はい。共通のセレクタと監視で動作する設計です。 【トラブルシューテ│ィング】 ・反映されない:chrome://extensions で拡張をリロード。必要に応じてサービスワーカー停止→自動再起動。 ・アイコンが切り替わらない:画像名(chat-hide.png / chat-restore.png)と manifest の指定を確認。 【変更履歴】 v1.0.8 — tabs 権限を削除しポリシー準拠 v1.0.7 — 初回公開(個別非表示/プレビュー復元/ON/OFF アイコン切替) │免責:本拡張は Google 公式ではありません。Gemini の UI 変更により動作が変わる場合があります。 🟢 Hide Gemini sidebar chats at the UI level — ideal for organizations where deletion/hidden history is disabled by policy. Overview This extension lets you hide individual conversations in the Gemini sidebar with an “×” button. Use the toolbar icon to toggle ON (hiding enabled) / OFF (Preview). In Preview mode, everything becomes visible and each hidden row shows a “↩ Restore” action. No server data is modified — it’s UI-only hiding with no data exfiltration. Features Hide a conversation row with “×” (display:none) Toolbar toggle: ON/OFF (Preview) “↩ Restore” in Preview mode to unhide items Local persistence across reloads (chrome.storage.local) Works independently of the sidebar’s open/close state How to use 1.Install and pin the extension 2.Open https://gemini.google.com/ 3.Click “×” on any sidebar row to hide it 4.Click the toolbar icon to enter Preview (show all); use “↩ Restore” on hidden items 5.Click the icon again to re-enable hiding (ON) Permissions & Data Permissions: storage (state persistence) Host scope: https://gemini.google.com/* Stored locally: IDs of conversations you chose to hide + ON/OFF flag No data leaves the device; no PII collection; no remote code FAQ Does it delete server data? No. It only hides rows in the UI. Server-side conversations remain intact. Does it work with English UI and dark theme? Yes. It’s designed with stable selectors and observers. Troubleshooting Not updating? Go to chrome://extensions, Reload the extension, and (if needed) stop/restart the Service Worker. Toolbar icon not switching? Verify image filenames (chat-hide.png / chat-restore.png) and manifest paths. Changelog v1.0.8 — Removed tabs permission to comply with Chrome Web Store policy v1.0.7 — Initial release (per-row hide, Preview restore, ON/OFF icon) Disclaimer: This is not an official Google product. UI changes in Gemini may affect behavior.
