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。

Tiff Viewer's advantage is ratings volume (213 vs 1) and iOS requirement (11.0 vs 16.0). On price, ads and device support there is nothing between them.
