Calculator Lock - Photo Vault vs Privately

Calculator Lock - Photo Vault is an Android privacy vault concealed behind a working calculator and opened with a 4-digit PIN. It stores photos, videos, audio, PDFs, files, and Secure Notes in encrypted app-private storage. Different PINs can open separate vaults without a visible session switcher. Users can search and pin encrypted notes, organize items in built-in folders, and restore deleted media or notes from Trash. The app displays photos, videos, audio, and PDF previews; unsupported files can be unlocked, exported, or shared. The maker describes screenshot protection and clipboard cleanup on sensitive flows. The free plan costs nothing and allows up to two personal vaults, with ads possibly appearing. There is no cloud backup or PIN recovery. Optional Intruder Detection may capture a front-camera photo after repeated failed attempts.

Privately is an iPhone vault for photos and videos, with media encrypted on the device. It splits files into 1 MB blocks protected by AES-256-GCM, while the user’s PIN wraps a master key stored in the iPhone Secure Enclave. Albums can have separate passwords, and their locked photos disappear from the timeline, search, and favorites; Face ID unlocking is optional. On-device Smart Search can find text in photos in 18 languages without sending the photos off the iPhone. Users can export a.privately backup and restore it on a new device with their PIN; the maker says backups can be kept in iCloud Drive or elsewhere. The maker says it has no accounts or servers holding photos, file names, or thumbnails. The Free plan costs nothing, with no sign-up required. Pro Yearly costs $39.99 a year and includes locked albums and encrypted backups. The yearly subscription has a 7-day free trial; the weekly subscription has no free trial. The app is only for iPhone and requires iOS 18.0 or later. The maker says forgotten PIN access or losing a device without a backup can mean permanent content loss.
