Google Photos Locked Folder vs CalcLock

Start with the job you need done

Google Photos Locked Folder works inside Google Photos. Its iPhone instructions say access uses Face ID, Touch ID or the device passcode; you cannot set a separate Locked Folder password. Items are excluded from the normal grid, memories, search and albums. CalcLock instead asks for its configured exact expression and two consecutive equals presses in a working calculator.

Follow the files beyond the unlock screen

Google lets you enable Locked Folder backup and access backed-up items on other devices signed into your account. Its documentation warns that unbacked-up items can be lost when the app is uninstalled or the device is lost. Moving an item without Locked Folder backup can remove its existing Google Photos backup. Check that setting before moving important pictures.

Make the practical tradeoff explicit

Choose based on the boundary you need. If someone legitimately knows your phone passcode, a folder using that same credential does not create a separate secret from them. If the goal is to prevent pictures from surfacing in memories or the normal photo grid, an existing-library feature may be the simplest workflow. Neither choice retrieves copies another person has already saved.

Test the complete workflow with harmless files

Before moving a large collection, select one unimportant image and record where each copy currently exists. Decide whether cloud access is wanted, then verify the backup setting and test access through the intended route. A successful move is not evidence that an independent copy exists. Never run an uninstall experiment with your only copy of a personal photo.

What CalcLock actually provides

CalcLock imports photos, videos and files into an equation-specific local vault and includes audio playback. The first equals press calculates; a second consecutive equals press opens the matching collection. Matching the numerical answer is not sufficient: the configured expression itself matters.

AES-256-GCM protects the stored files and manifest using a secret held in the device Keychain. This implementation has not had an independent security audit. CalcLock provides no export, sharing, sync, backup restoration or forgotten-equation recovery. Keep independent originals and do not rely on a new phone or reinstall to recover the vault.
