44Files in this directory are written with owner-only permissions so other OS accounts on the same machine cannot read them. The app encrypts stored sign-in tokens and similar secrets with the operating system's secure storage (see [Credentials](#credentials)), but not conversations, settings, or locally applied configuration, including an API key saved from the in-app configuration window. Protection at rest for those files depends on the device's full-disk encryption, such as FileVault or BitLocker.
