Export anything, anytime. Deploys anywhere A single Docker image runs on a $5 VPS, your homelab, or a Dokku one-liner. Healthchecks and Let's Encrypt are baked in - no ops team required. Private by default No telemetry, no tracking pixels. Self-host on your own server and TinyCld never phones home - no analytics, no crash pings, no metered usage reports. External email images are proxied through your server with a scoped token, so senders can't see your IP, read receipts, or user agent. Big tech sees nothing, because nothing is sent. Server-side image proxy for HTML email Invite-only signup - no public account creation One binary, one SQLite file, one place to audit Native protocols IMAP, SMTP, CalDAV, CardDAV, WebDAV - use Apple Mail, Thunderbird, any CalDAV client, or mount your drive as a network folder.

Multi-org Users can belong to multiple organizations with different roles. Shared calendars, contacts, mailboxes, and files within org boundaries. Web + Mobile One app for web, iOS, and Android - plus standard protocols so Apple Mail, Thunderbird, and Finder just work alongside. Real-time Live updates across all apps via server-sent events. No polling, no manual refresh - changes from other users and devices appear instantly.
