Network connections
Terminal sessions, SFTP, and monitoring connect to SSH servers you choose. Direct downloads may contact GitHub to check for and download updates; the App Store edition uses the App Store. Opening website, help, or feedback links connects your browser to the corresponding website.
Credentials
SSH passwords and passphrases are stored in the local macOS Keychain. Private keys imported into the vault also use Keychain; file-based keys use your chosen local paths. Password authentication sends credentials over an encrypted connection to your chosen server; key authentication signs locally without uploading private keys to the developer.
Local data
Session configuration, file authorization bookmarks, and settings are stored locally. Terminal data and file operations are transferred between your Mac and the servers you choose; drag downloads temporarily stage files for Finder. You manage local sessions and any files you import, export, or download.

Session logs
When session recording is enabled, terminal content is saved to your chosen local log directory as plain text or raw streams with size-based rotation. Logs can contain sensitive command output; enable, manage and share them accordingly.
