<div class="terms-content">
<p class="mb-4">本アプリ「VRMアバターAR (VRM1.0正式対応)」のご利用前に、以下の内容をご確認・同意ください。</p>
<strong class="text-blue-400">1. VRMファイルの扱いについて</strong>
<p class="mb-4 text-sm">
読み込まれたVRMファイルおよびカメラ映像は、お使いのブラウザ内（クライアントサイド）でのみ処理されます。
外部サーバーへのアップロードや保存は一切行われません。
ページを閉じると、読み込んだデータは破棄されます。
</p>
<strong class="text-yellow-400">2. プライバシー保護について</strong>
<p class="mb-4 text-sm">
本アプリの「背景除去（マスク）」機能はAIによる推定処理であり、100%の精度を保証するものではありません。
環境や条件により、背景や人物の一部が意図せず映り込む可能性があります。
動画の配信や共有を行う際は、プライバシー保護が完全ではないことを理解した上で、十分ご注意ください。

<strong class="text-orange-400">4. 誤検知・環境について</strong>
<p class="mb-4 text-sm">
カメラの画角内に、ポスターの人物、人形、フィギュア、ハンガーにかかった服など、
<span class="underline font-bold">「人の形状に見えるもの」が存在すると、AIが人物と誤認する可能性があります。</span>
これらが画角に入らないよう調整してご利用ください。

<strong class="text-green-400">5. マイク利用について</strong>
<p class="mb-4 text-sm">
リップシンク（口パク）機能のためにマイク音声の音量レベルのみを使用します。
<span class="underline font-bold">音声データの録音・保存・外部サーバーへの送信等は一切行いません。</span>
