Everything stays on your machine

No servers, no accounts, no syncing. Calypsov just zips up what you choose and hides it, locally, until you decide to bring it back.

One-click protection

Flip one dial to zip up and hide everything you've configured. Flip it back to restore it exactly as it was.

Protection Profiles

Keep separate setups for different contexts — like Personal and Work — and switch between them instantly.

Folders, files & browsers

Protect whole folders, individual files, and even a selected browser profile's bookmarks and saved logins — all in one sweep.

Turbo Zip

Splits large batches of folders across multiple CPU cores for noticeably faster protection once you've configured 20+ folders.

Optional extra encryption

Add an extra layer of protection to the zipped archive itself, and keep your configured path list hidden from anyone else using your computer.

Searchable activity log

See exactly what the app has done, with a searchable log viewer for peace of mind and troubleshooting.
