- MLS end-to-end encryption
- Post-quantum protection
- No phone number
Everything you need to talk
The features you expect from a messenger — every one of them end-to-end encrypted.
Calls
Audio and video calls one-to-one, and group calls with up to 25 people. Your phone encrypts the sound and video.
Files and voice messages
Photos, documents and voice messages. Each file is encrypted on your phone before it is sent.
Channels and polls
Announcement channels for your company and polls in any chat to hear from everyone quickly.
Reactions, replies, edits
Reply with a quote, react, and fix a message you've already sent — for everyone in the chat.
Backups and new phones
Automatic backups encrypted with your recovery key, and a QR transfer when you switch to a new phone.
Fingerprint or Face ID
PIN and auto-lock — and you can unlock the app with your fingerprint or face.
Protection from scam links
Cifrela warns you about suspicious addresses: look-alike letters, shortened links, an IP address instead of a site name.
Clean, business-like design
Light and dark themes and clear screens with nothing extra — so you can get on with work.
Screenshots show the Ukrainian interface.
Security without compromise
Encryption keys are created on your phone and never leave it. Not even we can read your conversations.
End-to-end encryption for everything
Messages, photos, documents, voice messages and your profile are encrypted with the MLS standard (RFC 9420), and call keys are agreed through it.
Post-quantum protection
By default a hybrid of ML-KEM-768 + X25519: what is recorded today can't be decrypted even by a future quantum computer.
No phone number
Sign up with an email address or an invitation. Your address book never leaves your phone.
No Google
Notifications on Android work without Google services: the server only says "something new".
Servers in the EU
The server and data are in a data centre in Germany. The server itself only sees ciphertext.
No ads, no trackers
No analytics and no selling of data. This website doesn't use cookies either.
Cifrela for business
A private network where employees talk only to each other and the owner manages the team. Neither the owner nor we can read the conversations.
- Employees join by the owner's invitation
- A colleague directory with names and job titles
- Announcement channels and bots for your company's systems
- Remote wipe of a lost phone
- Company files stay in your own S3 storage
Frequently asked questions
Who can read my messages?
Only the people in the chat. Messages are encrypted on the sender's phone and decrypted only on the recipients' phones. The server, your internet provider or café Wi-Fi only ever see ciphertext — and we don't have the keys.
Why no phone number?
A phone number reveals too much about a person. With Cifrela you sign up with an email address or an invitation from a friend or your company. Only someone who knows your exact name or email can find you — and you can turn that off.
What does the Cifrela server see?
Only the service data needed to deliver messages: who shares a chat with whom, when and how much was sent, and your user name. It can't see the content of messages, files or calls. Details are on the Security page.
What if I lose my phone?
If you turned on backups, you can restore your conversations on a new phone with your recovery key — write it down on paper. Without the key no one can open the backup, not even us. For company accounts, the owner can remotely wipe Cifrela data on a lost phone.
Can I use it on several devices?
For now one account works on one phone. When you change phones, move everything from the old one to the new one with a QR code — nothing gets lost.
Is there Cifrela for iPhone?
The iPhone version is being prepared for the App Store. On Android you can download the app from our website today; it is coming to Google Play soon.
Where is my data stored?
Your conversations and keys stay on your phone in an encrypted file. The server runs in a data centre in Germany (EU) and stores only ciphertext. A company can keep its files and backups in its own S3 storage.
Does Cifrela show ads?
No. The app has no ads, no trackers and no analytics, and we don't sell or share data with advertisers. This website doesn't use cookies or counters either.
Which languages does the app support?
English, Ukrainian, Polish, German and Spanish.
