Sendant is a private, encrypted messenger built on a simple promise: your conversations belong to you. Messages are end-to-end encrypted by default, your keys never leave your device, there's no central server quietly logging who you talk to — and no phone number, email, or account required to start.
It feels like the messengers you already know — fast chats, groups, attachments, reactions, and disappearing messages — but the trust model underneath is different.
WHY SENDANT
• End-to-end encrypted by default (X3DH + Double Ratchet). Only you and the people you're talking to can read your messages.
• No phone number, email, or account. Your identity lives in cryptographic keys held on your device, not tied to your SIM.
• Messages that don't get lost. Your message is sealed on your device and held in a store-and-forward mailbox the servers can't read, so it waits and delivers when your contact reconnects.
• Less metadata. We minimize the "who talked to whom, when" trail that centralized apps collect by default.
• Verify the people you trust. Confirm a contact with a QR code or safety number, and get a clear, plain-language warning the moment something changes.
• No ads, no tracking SDKs.
TRUST YOU CAN READ
Security here speaks plain English. Sendant shows "Verified," "End-to-end encrypted," and "Safety number changed" — never cryptographic jargon.
PRIVACY BY DEFAULT
No phone number, email, or account required. Local-first storage on your device. Your keys stay under your control.
Private by default. Calm by design.
더 보기 Messages now arrive while you're on the Chats list or anywhere else in the app, and a burst from a session reset delivers cleanly instead of stalling. Delivery receipts retry on their own, so a delivered message no longer sits on a single tick. If a message is still undelivered after five minutes, a banner offers a one-tap session repair. Video calls start on the loudspeaker, video previews play with sound, and a lost Pro passcode can be recovered by email.

Linked browsers stay in sync across photos, voice notes, files and reactions. Sending is instant: tap Send and the composer is ready again at once, while the message shows a clock until it is sent, including in groups until a member accepts. Long chats open, scroll, react, play and receive without stutter. Network blips show a quiet Connecting… strip. Answering a call connects faster and rings your whole ringtone. Voice notes start snappier and support up to 10 minutes, with encrypted drafts, preview and retry. Fixed the paperclip turning black. Photos in one-to-one chats show a quick preview first and are now encoded at 1440 px / quality 85, never lower; larger photos use encrypted media instead of being compressed. Adding someone to a group no longer stalls when their app hasn't shared its key yet — Sendant retries automatically. A failed message's Resend reconnects or explains why, and texts sent from the linked web app deliver through your phone when the browser can't start the chat. Fixed a fast double tap on the voice recorder that could show a stop error and leave the recording row stuck. Fixed a just-sent photo showing as unavailable on the sender's screen. Group delivery ticks now match the delivered and read count after a member updates or leaves a group.

1.0.13 5일 전
• Fixed the attachment paperclip intermittently appearing black and improved attachment-menu accessibility on iPhone.
• Record voice messages up to 10 minutes. Longer notes use end-to-end encrypted media and require an updated recipient app.
• Chats now discover long-note support after an upgrade, fixing an incorrect recipient-update warning.
• Stop and listen before sending. Completed recordings stay as encrypted drafts until you send or discard them.
• Retry failed sends without recording again.
• Longer notes are available to download for up to 14 days, or less with a shorter disappearing-message timer. Backups keep these message entries without their audio.
1.0.12 10월 17일
• If you turned Sendant's notifications off, the reminder's "Open settings" button now takes you straight to the switch that turns them back on, and the Notifications setting shows whether they are actually on.
• The Backup screen now shows a running backup's progress, with the current step, a percentage and a Stop button.
• Chats no longer flash an "Account is locked" banner while a backup saves.
1.0.11 10월 12일
• Photos of any size now send. Big screenshots and camera photos are compressed instead of refused as "Too large to send".
• Videos up to 10 minutes long, and files up to 5 MB, can be sent to contacts on the latest version.
• Incoming calls now ring through the iPhone's call screen, like a phone call.
• The screen stays on during video calls.
1.0.10 10월 5일
Calls: the audio button now shows when sound is on a Bluetooth headset, with the headset's name. With a headset connected, tap it to choose Phone, Speaker or the headset.
Fixes:
• Read receipts, reactions and call signals no longer fail after you send a message.
• Tapping a voice note twice quickly no longer stops it playing.
Still no account, no phone number, and no key that leaves your device.
1.0.9 10월 1일
Changing the text size while Sendant is open now applies right away without clipped text, and keeps the chat you had open and your unsent message. Screen titles no longer split mid-word at the largest sizes. A name you give a contact now stays, even when they change their own name; their name shows under yours in the chat header. Clear the name to go back to theirs. Group messages and call screens use your name for them too.
1.0.7 9월 28일
Backup fixes:
• Back up now waits until Google Drive is connected, instead of asking for a password first.
• Replacing another account's backup asks for your password once, instead of repeating the same question.
• At large text sizes, backup password windows scroll and keep Close on screen.
Still no account, no phone number, and no key that leaves your device.
1.0.6 9월 27일
New: listen to voice messages privately. While a voice message plays, hold your phone to your ear and it switches to the earpiece, replaying the last 2 seconds so you don't miss a word. Lower the phone and it goes back to the loudspeaker.
Headphones and Bluetooth stay as they are, and calls are never affected.
Still no account, no phone number, and no key that leaves your device.
Also in this update: security fixes. When someone asks to switch a call to video, your camera turns on only after you tap to accept. And a clearer screen when a contact needs to update Sendant to receive videos.
1.0.5 9월 25일
New: video messages. Pick a clip of up to 3 minutes, preview it, and send. It is compressed and end-to-end encrypted on your phone, and your contact taps to download and play it.
Also in this update:
• New chat opens the conversation as soon as your contact is added
• One tap places exactly one call, and cancelling a ring mid-setup no longer crashes the app
• Automatic encrypted backup can now run weekly
• The app lock always asks you to authenticate
• Chat bubbles no longer jitter, and a message is never saved twice
• Fewer false "messages may be lost" warnings, and conversations repair themselves more reliably
Still no account, no phone number, and no key that leaves your device.
1.0.4 9월 24일
Everything the Android app does, the iPhone app now does too.
• Group chats — create an encrypted group of up to 16 people, and open the groups you were already a member of
• Link a browser to your iPhone identity and carry the same conversations to a computer
• Video calls, with camera switching, video mute and speaker control
• Encrypted Google Drive backup, and restore that now moves between iPhone and Android in either direction
• Share into Sendant from any app, and let your recent chats appear at the top of the iOS share sheet
• Incoming calls ring your phone while it is locked, instead of arriving as a silent notification
• Notifications name the person who wrote to you
• Save photos, voice clips and documents out of a chat to your phone
None of this changed how Sendant protects you. There is still no account, no phone number, and no key that leaves your device.
1.0.3 9월 22일
Reliability and security improvements:
• Messages sent from a linked device, such as Sendant in a web browser, now arrive in your existing conversation with that person instead of appearing as a second, separate contact. If a chat was already split this way, it merges back on its own.
• Fixed a case where a new contact's very first message could fail to arrive while another conversation was open.
• More reliable message and incoming-call notifications when several events arrive together.
• Notification registration now handles preference changes and network timeouts more reliably.
• Safer link previews and stronger protection for locally stored app data.
• Updated dependencies and additional security fixes.
1.0.2 9월 21일
Notifications now work on iPhone.
Until this build, Sendant never told you a message had arrived. That is fixed, along with several other things the iPhone was missing.
• Push notifications for new messages, so you know without opening the app
• Answer or decline an incoming call straight from the notification
• Start a voice call from any conversation
• The speaker button now actually switches to speakerphone
• A ringing tone while your call connects, so you can tell it is working
• Large photos and screenshots now send — they are resized for you
• One-time prekeys, strengthening forward secrecy for the first message you send to a new contact
