End-to-end encrypted

Private messaging that stays private.

A simple, fast messenger for the people you trust — with end-to-end encrypted chats, groups, and voice & video calls, plus channels when you want to broadcast in the open. Your conversations belong to you, not to us.

Everything you need to talk

One private app for staying in touch

Message, call, and share with friends, family, and communities — your private conversations end-to-end encrypted by default.

Private chats

One-to-one messages secured with end-to-end encryption, so only you and the person you're talking to can read them.

Group chats

Create private groups for family, friends, or your team. Every group message is end-to-end encrypted.

Channels

Broadcast updates to everyone who follows you. Public channels are open by design; private ones stay end-to-end encrypted, like your chats.

Voice & video calls

Crisp one-to-one calls, with media encrypted end-to-end between participants.

Media & files

Send photos, videos, voice notes, and documents. Attachments are encrypted just like your messages.

Across your devices

Use LEWO on your phone, on the web, and on desktop — your conversations stay in sync, always encrypted.

Privacy by default

Your messages are yours alone

LEWO encrypts your conversations on your device before they're sent. The keys that unlock them never leave your phone — which means not even we can read what you say.

  • End-to-end encryption on your private chats, groups and calls — automatically
  • Your private keys are generated and stored only on your device
  • Our servers can't read your messages — they relay only encrypted message content
  • Forward secrecy: even a future key compromise can't unlock past chats
  • The encryption core is open source — published so anyone can verify it

Don't trust us — verify us

The encryption core is open source

The cryptographic core of LEWO — the exact code that agrees on keys and turns your private messages into ciphertext — is published publicly, so anyone can inspect how the encryption works and confirm it does what we say.

lewo-e2ee-core — the published encryption core, with its full test suite. Clone it, read it, run the tests yourself: the same key agreement and message encryption that protect your conversations in LEWO.

To be precise: it's the encryption core that is open source — the code responsible for end-to-end encrypting your private conversations. Read how LEWO encryption works, or meet the person building LEWO.

Free for everyone

Free to use, supported by ads

LEWO is free. To keep it that way, we show ads in parts of the app — but your conversations are off-limits.

  • Because your chats and call media are end-to-end encrypted, their content is never read by us or by advertisers
  • Ads are never based on the contents of your messages, calls, or media
  • You're a person, not a profile built from your private conversations
  • Exactly what data is and isn't used for ads is spelled out in our Privacy Policy
