Most email apps are built around your data. Tacitus Mail is built around your privacy. Tacitus Mail is a private-first email and communications client that gives you back control over every message you send, and every conversation you have. End-to-end PGP encryption, private messaging, calendar, and contacts โ all in a single app, with no ads, no tracking, and no compromise. SECURE EMAIL, DONE RIGHT Email was never designed with privacy in mind. Tacitus Mail fixes that. Every message can be signed and encrypted using OpenPGP โ the gold standard for email security. Your private key is generated on your device and never transmitted anywhere. The Tacitus servers handle delivery, not decryption. Not even we can read your mail. โข Full HTML composition with rich formatting โข PGP encryption and digital signatures on every message โข Automatic public key discovery for Tacitus contacts โข Reply, reply-all, forward โ with full encryption chain โข Inline attachment support โข Smart inbox with instant push notifications โข Handles slow or unreliable connections gracefully โ failed downloads retry automatically so you never miss a message โข Works on low-bandwidth networks without sacrificing reliability PRIVATE MESSAGING & CHAT Tacitus Mail includes a built-in private messaging system for real-time communication with other Tacitus users. Messages are delivered instantly, and your conversation history stays on your device. โข Real-time private chat with contacts โข Messages appear instantly โ no need to refresh โข Home screen widget showing your most recent conversations at a glance โข Unread badges and push notifications for new messages โข Chat history synced securely across your devices CALENDAR & CONTACTS Your communications don't happen in isolation. Tacitus Mail integrates your schedule and your address book directly into the experience. โข Calendar view alongside your inbox โ no context switching โข Native calendar event integration โข Contacts sync across all your devices and the Tacitus web app โข Import your existing address book and use it everywhere โข Your contact data stays in your account โ never sold, never analyzed OPEN STANDARDS. ZERO LOCK-IN. Tacitus Mail is built on open, proven standards โ IMAP, SMTP, and OpenPGP. There is no proprietary format, no walled garden, and no lock-in. You can export your data at any time, use any compatible email client, and migrate away with zero friction if you ever choose to. Your emails are yours. We just help you send them privately. WHY TACITUS MAIL? The name comes from the Roman historian Tacitus, who documented power and corruption when it was dangerous to do so. We believe private communication is a fundamental right โ not a feature you unlock with a premium subscription. โข No advertising. Ever. โข No behavioral tracking or profiling. โข No reading of your messages for any purpose. โข Transparent privacy policy with no hidden clauses. โข Your encryption keys never leave your device.
