# Privr > Privr is a fast, privacy-focused email client for macOS. Built with Rust and Tauri, it features end-to-end encryption (E2EE), encrypted local storage, tracker blocking, JMAP and IMAP/SMTP account support, and RSS feeds. ## What is Privr? Privr is a native macOS desktop email client designed for users who value privacy and speed. Unlike web-based email clients, Privr runs entirely on your Mac with no browser engine — just native performance. All data is stored locally with AES-256 encryption, and no email content ever leaves your device unencrypted. Messages between Privr users are automatically end-to-end encrypted after one email exchange — no setup required. Privr supports modern JMAP accounts, common IMAP/SMTP providers, and RSS-style feeds in one workspace. ## Key Features - **Native macOS app**: Built with Rust and Tauri for maximum speed. Starts in milliseconds, stays responsive with thousands of emails. - **End-to-end encryption (E2EE)**: Automatic end-to-end encryption between Privr users. After one email exchange, all subsequent messages are encrypted using Ed25519 and X25519 cryptography. Key exchange happens over email itself — no external servers needed. - **Encrypted local storage**: All cached emails are stored in an encrypted database (SQLCipher). Credentials are protected in an encrypted vault (IOTA Stronghold with Argon2). - **Tracker blocking**: Detects and removes tracking pixels from dozens of known services. Cleans tracking parameters from URLs. - **Phishing & spam analysis**: On-device analysis detects phishing, spoofing, and suspicious attachments. Every email gets a safety score with explanation — no data shared externally. - **Multi-account & Unified Inbox**: Manage multiple email accounts in one place. View all inboxes combined or switch between accounts. - **JMAP and IMAP/SMTP accounts**: Uses JMAP (RFC 8620/8621) where available, with IMAP/SMTP presets for common providers and custom servers. - **RSS, Atom, and JSON Feed subscriptions**: Follow feeds beside email, refresh feeds, mark items read, bookmark items, and customize feed columns. - **Real-time push notifications**: Instant push notifications with native macOS dock badge. - **Rich text composer**: Formatting toolbar, auto-saved drafts, reusable templates, multiple sender identities with signatures, and drag-and-drop attachments. - **Undo send**: 10-second grace period after sending. Cancel a sent email and return to editing. - **Snooze & Send Later**: Schedule emails to send later, snooze messages to a better time, and mute busy threads. - **Sieve mail filters**: Create, edit, and manage server-side filter rules directly from the app. Includes vacation autoresponder. - **One-click unsubscribe**: Automatically detects unsubscribe options and offers one-click unsubscription. - **CardDAV address book**: Full address book with sync, contact groups, Apple Contacts import, and smart autocomplete. - **Conversation view**: Emails grouped in conversation threads with chronological history. - **Keyboard shortcuts**: Native macOS shortcuts for all actions, triage keys for quick sorting, bulk operations. - **Customizable UI**: Classic and modern layouts, adjustable columns, font size, UI density, dark mode, multilingual interface (Dutch, English, German, French & Spanish). - **Link safety**: Homograph attack detection and URL mismatch warnings before opening links. - **Dual content sanitization**: Email content is filtered in two layers for maximum protection against malicious messages. ## Supported Email Providers - **Fastmail** (JMAP API token / Bearer authentication) - **Stalwart Mail Server** and **Cyrus** JMAP deployments - **iCloud Mail** and **Fastmail IMAP/SMTP** - Custom **JMAP** and custom **IMAP/SMTP** servers ## Technology Stack - **Backend**: Rust - **Framework**: Tauri v2 - **Frontend**: React 19, TypeScript - **Protocols**: JMAP (RFC 8620/8621), IMAP, SMTP, RSS, Atom, JSON Feed - **Encryption**: AES-256 (SQLCipher for local database), IOTA Stronghold (credential vault), Ed25519/X25519 (E2EE), ChaCha20-Poly1305 (message encryption) - **Platform**: macOS ## Availability Privr is currently in development and will be available soon.
