## What is CryptVault?

CryptVault は、写真・動画・書類を「あなたの鍵で」暗号化して守る、プライバシー第一のファイル金庫です。

■ アカウント不要ですぐ使える
インストールしてすぐ、端末内に暗号化Vaultを作成。写真アプリやファイルから追加すると、その場で暗号化して保存します。クラウドも登録も不要です。

■ 端末内で完結する暗号化
ファイルは rclone crypt 互換の強力な暗号（scrypt 鍵導出 ＋ XSalsa20‑Poly1305）で暗号化されます。暗号鍵は端末の Keychain に保存され、外部に送信されません。

■ 自分のサーバーにも“暗号化したまま”
必要なら WebDAV（Hetzner Storage Box、NAS、Nextcloud など）を設定して、暗号化済みファイルだけをアップロード。平文や鍵がサーバーに渡ることはありません。同じ鍵を使えば、複数の端末で同じVaultを読めます。

■ 写真も動画もそのまま再生
サムネイル一覧、フルスクリーン表示、動画再生（mp4/mov に加え、webm/mkv/avi なども）に対応。

■ 起動時ロック
Face ID / Touch ID / パスコードで、アプリ全体をロックできます。

あなたのデータは、あなたのものだけ。CryptVault は、それを技術で保証します。
