Cryptomator vs CalcLock

Start with the job you need done

Cryptomator describes client-side encryption for files and filenames, with password-protected vaults stored through compatible storage services. Its official site explains access across devices and distinguishes the individual product from its team offering. CalcLock uses an exact equation and a device-bound secret for its own local iPhone vault.

Follow the files beyond the unlock screen

The storage location is part of the choice. Cryptomator is aimed at encrypting files within a broader storage workflow; confirm compatibility with your chosen service and device before relying on it. CalcLock does not sync or transfer its vault to cloud storage. Its calculator is an entry interface, not a connector to a third-party storage provider.

Make the practical tradeoff explicit

A general file workflow asks you to think about folders, storage providers, passwords and the applications that open decrypted files. A local photo collection can feel simpler because fewer services are involved. The tradeoff is that the local collection must not become the only surviving copy of something important. Simplicity of entry and resilience to device loss are different requirements.

Test the complete workflow with harmless files

When evaluating an encrypted file tool, use non-sensitive test documents and keep originals. Confirm the storage location, the way files appear while locked and unlocked, and the steps to open a file on each device you plan to use. Close the viewing app afterward and consider temporary copies or downloads it may have created. Encryption of one stored vault does not automatically govern every application that handles an opened file.

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.
