💰 「30%OFF」、本当にお得？ 買う前に見抜く

DLsite・FANZA・MGS・DUGAの作品ページに、オトナ録が毎日記録している値段の札を1枚だけ出します。 セール中の割引率だけでは「前はもっと安かった」が分かりません。札の1行目で結論が分かります。

  • ✅ 記録したどの日より安い
  • ✅ 記録上の最安と同じ
  • ⚠️ 記録ではいまより安い日があった（差額つき）

🏷️ 札に出ること

  • 記録上の最安と、その日付
  • 値下げの回数と最大割引率（定価のときは最後に値下げされた日）
  • 記録した日数（2週間に満たない作品では「最安」を強く言いません）
  • 判定はページに出ている値段と記録を比べます（読めない販売元では「◯月◯日時点」と日付つき）

📋 一覧でもひと目で

セール一覧・ランキングでは、値下げ中の作品の題名の横に「記録上の最安 ¥440」のような小さな札が付きます。開かなくても、どれが本当に下がっているか分かります。

🔒 安心して使える作り

  • 見た作品は送りません。値段の記録（約100KB）を1日1回まとめて取り、照合はブラウザの中だけ
  • 販売元のリンク・購入ボタン・Cookieには触りません
  • 記録の無い作品では何も出しません。クーポン・ポイント還元・会員割引は含みません
  • コードは圧縮なし（MIT）

📱 対応

  • DLsite（日本語・英語）／FANZA（同人・動画・アニメ・PCゲーム・電子書籍）／MGS動画／DUGA
  • PC（Tampermonkey・Violentmonkey）／iPhone・iPad（Userscriptsアプリ）／Android（Firefox＋Tampermonkey）
  • スマホでは購入ボタンに重ならないよう、右端の小さな札から開きます

7,800件以上（2026年10月）を毎日記録中。無料・登録不要。 詳しい説明と入れ方： https://otonaroku.com/tools/price-overlay/

English: Shows the lowest price we have recorded, when it was, how often the work was discounted and how many days we have tracked it — one small card on DLsite, FANZA, MGS and DUGA pages, and labels next to discounted works on lists. It compares the live page price with our daily record, never sends which works you view and never touches store links or cookies. Details: https://otonaroku.com/en/tools/price-overlay/
