Photo Vault: Secure Gallery

Calculator Lock - Hide Photos & Videos Vault is a secure vault app that hides personal media behind a calculator-style PIN. Import photos, videos, and files into the private vault; access is protected by PIN or pattern, and the discreet calculator UI helps keep your vault concealed even when others glance at your screen. Note that the app does not access your Photos app; media must be manually imported, and uninstalling the app permanently deletes stored data.

Key features include Intruder Alert (captures a photo of failed access attempts), a private video player, secure notes, a private browser, and app icon customization for discretion. It emphasizes privacy by design, offering multiple lock options and a straightforward password recovery flow inside the app.
