YOHAKUは、一日の終わりに頭の中の続きを3行だけ書き、明日の自分へ預ける静かなジャーナルです。 急かさず、評価せず、連続記録を強く求めません。書いた夜の積み重ねは、ホーム画面の樹と月ごとの森に残ります。 ■ 3つの記録モード 【いつもの3行】 今日感じたことを、3行だけ残します。 【明日に預ける】 今、頭に残っていること、明日へ持ち越すこと、今夜は手放すことを書きます。記録後に「明日に預ける」「最初の一歩」「今夜は置いてよい」の3項目へ整理し、自分の言葉で修正できます。 【仕事を終える1分】 仕事の続きを抱えたままにしないための短い終了モードです。明日の最初の一歩を残し、今日はここまでと区切ります。 ■ 任意のAI整理 AIは設定で明示的にオンにした場合のみ使われます。オフのままでも、記録、整理、樹の成長は完了できます。通信できない場合も、入力した3行を使って端末内で整理します。 ■ 樹と森 記録を重ねるほど樹がゆっくり育ちます。月ごとの記録は森から振り返れます。 ■ 声で3行 マイクを自分でタップしたときだけ音声入力が始まります。YOHAKUは音声ファイルを保存しません。 ■ 静かなリマインダー 選んだ時刻に短い通知を送ります。通知本文にジャーナルの内容は表示しません。 ■ プライバシー ・アカウント登録不要 ・記録は原則端末内 ・iCloud同期は任意 ・広告トラッキングなし ・AI送信は明示同意時のみ、本文は合計500文字以内 ・AIを使わなくても記録を完了可能 YOHAKUは医療機器ではなく、診断、治療、カウンセリングを提供しません。 利用規約 https://apps.basedock.app/legal/terms プライバシーポリシー https://apps.basedock.app/legal/privacy お問い合わせ https://apps.basedock.app/support
