Calculator Lock - Photo Vault vs GalleryVault

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.

GalleryVault is an Android and iOS app for keeping photos, videos, and other files in a private vault. Users can add or capture photos and videos; supported file types also include audio and documents. The maker describes stored files as encrypted, and says media on SD cards can be encrypted too. A private browser can download all images and videos from a web page with one tap. For disguised access, the app can hide its icon and provides a secret door. GalleryVault includes backup and restore, and its help page says it can connect to Google Drive to store encrypted files. Free users can upload up to 100 new files to Google Drive per month. The maker says data is kept on the user's device and recommends backing it up. Deleted photos remain in the recycle bin for 60 days before automatic deletion. Paid features include fingerprint unlock, folder lock, fake passcode, random PIN keyboard, shake-to-close, and break-in alerts. A free plan is listed; the seven-day trial applies to six-month and one-year subscriptions. Paid options include 9.90 CNY a month and 68 CNY a year.
