01 / Zero cloud

Your secrets stay on your machine.

TermKey is a local-only encrypted vault. There is no account, sync service, or remote endpoint between you and your data.

Encrypted backup and recovery remain in your hands. Vaults upgraded from the legacy format use a new recovery phrase configured in Settings.
