Guvercin
What Guvercin is
Guvercin is a desktop email client with a built-in calendar, address book, and task list. It connects multiple IMAP/SMTP accounts and offers one-click Google sign-in, but does not provide an email address. Calendar events sync with CalDAV and Google Calendar, contacts with Google Contacts, and tasks with Google Tasks. Synced mail, attachments, inline images, and search remain available offline, with offline actions replayed after reconnection. The app stores messages, drafts, attachments, events, contacts, and tasks in an encrypted local database; its maker says it operates no servers or cloud storage. Database encryption uses SQLCipher, cached files use XChaCha20-Poly1305, and the encryption key is stored in the user profile rather than the OS keychain. Guvercin has no analytics, telemetry, crash reporting, advertising, or tracking code; remote images load only when requested. It supports Linux, macOS, Windows, and the web, with 64 interface languages. Version 0.1.0 is described as an early release with possible rough edges.
