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. โ€ข Full HTML composition with rich formatting โ€ข PGP encryption and digital signatures on every message โ€ข Automatic public key discovery for Tacitus contacts โ€ข Reply, reply-all, forward โ€” with full encryption chain โ€ข Inline attachment support โ€ข Smart inbox with instant push notifications โ€ข Handles slow or unreliable connections gracefully โ€” failed downloads retry automatically so you never miss a message โ€ข 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. โ€ข Real-time private chat with contacts โ€ข Messages appear instantly โ€” no need to refresh โ€ข Home screen widget showing your most recent conversations at a glance โ€ข Unread badges and push notifications for new messages โ€ข 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. โ€ข Calendar view alongside your inbox โ€” no context switching โ€ข Native calendar event integration โ€ข Contacts sync across all your devices and the Tacitus web app โ€ข Import your existing address book and use it everywhere โ€ข 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. โ€ข No advertising. Ever. โ€ข No behavioral tracking or profiling. โ€ข No reading of your messages for any purpose. โ€ข Transparent privacy policy with no hidden clauses. โ€ข Your encryption keys never leave your device.

The honest translator. No account. No tracking. No surprise charges. Cipher translates right on your iPhone โ€” your words stay on your device, not on someone's server. Most translator apps trap you: a paywall the second you open them, a pre-checked $6.99/week plan, a "free trial" toggle that's off by default, and legal pages that don't even load. Cipher is the opposite. WHAT YOU GET, FREE โ€ข Unlimited on-device text translation โ€” works on a plane, abroad, with no signal โ€ข Voice conversation mode โ€” speak, and Cipher transcribes and translates on-device โ€ข Camera translation โ€” point at a menu or sign and read it in your language, on-device โ€ข The translator keyboard โ€” translate as you type in any app, free every day up to a generous limit, with a reliable backspace that never eats your message โ€ข No ads. Ever. PRIVATE BY DESIGN โ€ข Text, voice and camera run on your phone using Apple's on-device engine โ€” nothing uploaded โ€ข No account, no sign-up, no email, no tracking, no analytics SDKs โ€ข We can't read those translations because we never receive them โ€ข Two opt-in online features โ€” the keyboard's Cloud Translate and the "Translate with Cipher" share action โ€” send only the text you choose to a translation service so it comes back translated, then forget it. The keyboard's is off until you enable it. Everything else stays on your phone. HONEST PRICING โ€ข Cipher Pro: $3.99/month, $27.99/year (7-day free trial), or pay once $67.99 โ€” yours forever โ€ข No weekly plan. No pre-checked options. No dark patterns. โ€ข Before any charge, you see exactly what you'll pay and when. Cancel in two taps. PRO UNLOCKS โ€ข Unlimited keyboard translate โ€” type in any app with no daily limit โ€ข Our highest-quality cloud model for the keyboard โ€” for nuance and tone โ€ข Offline language packs โ€” download once, translate with no connection Built by the team behind Metadata Cleaner โ€” privacy is the whole point, not a marketing line.
