# ZapLock

> ZapLock encrypts any folder in place on macOS, Windows, iPhone, iPad and Android. The folder keeps its name and its path, and you unlock it with your ZapQR sign-in. You can share a folder with another ZapQR account and take that access back at any time. Free to download on the App Store, the Mac App Store, the Microsoft Store and Google Play. The Free plan locks one folder; Personal adds unlimited folders and sharing. Made by DaSecure Solutions LLC (United States).

Key facts:

- Encryption happens where the folder already sits — no disk image, no vault folder to move work into, no new drive letter. Aliases, backups and sync clients keep working.
- AES-256-GCM, encrypted and decrypted on the device. The key is split in two; the ZapQR account service holds one half, and that half alone decrypts nothing. File contents, file names and a whole key never leave the device.
- Works on folders on an internal disk, an external or USB drive, or inside a folder synced by Dropbox, Google Drive or iCloud.
- Share a folder to another ZapQR account by email address; revoke it and a folder they have open locks itself (an offline device locks once its offline timeout runs out). Sharing needs the Personal plan.
- While a folder is locked, AI tools on the same computer (assistants, coding agents, search indexers) see only ciphertext: encrypted file names and encrypted contents. This holds while it is locked — a folder unlocked in place is ordinary files again for everything on that computer, AI tools included, until it is locked. Browsing it inside the ZapLock app, without unlocking in place, keeps the folder itself encrypted: only a file you open gets a temporary readable copy, and locking removes it.
- One documented vault format across platforms: a folder locked on a Mac opens on Windows, iPhone, iPad or Android.
- Team plan ($9 per seat a month): folders belong to the team; removing a person deletes their share of every team folder's key, so their next unlock is refused, while everyone else keeps access.
- Requires a free ZapQR account.
