Private messenger · Swiss relay
Write freely.
Your messages.
Your privacy.
Liberty is the messenger for confidential conversations: end-to-end encrypted, no phone number, no email address – and nothing is stored on the server. Your messages belong to you and the person you're talking to. Nobody else.

Why Liberty
Privacy through data avoidance
Other messengers try to store as much data as possible, as securely as possible. Liberty takes a simpler path: data your communication doesn't need is never collected centrally in the first place.
End-to-end encrypted
Messages and media are encrypted on your device and only become readable again on the recipient's device.
Server stores nothing
The Swiss relay passes encrypted data through its RAM only. No disk, no archive, no copy.
Your data, your device
Contacts, chat histories and private keys stay locally on your devices.
Ad-free
No ads and no promotions – in Liberty, it’s all about your conversations.
No plugins
Liberty contains no plugins. There are no add-on modules that hook into your chats.
No built-in bots
Liberty has no built-in bots and no AI assistants. Nothing reads along automatically or replies on your behalf.
Help in a group chat
Your questions are answered in Liberty’s own support group chat – right inside Liberty.

For businesses
Confidential data doesn’t belong in just any messenger
Bank details, passwords, contracts or HR data are often sent quickly by messenger in everyday work – usually through services never designed for it. Liberty is built for exactly this kind of content: end-to-end encrypted, no phone number, and the server stores nothing. Files up to 3 GB and groups of up to 5000 members with roles make Liberty usable for entire teams.

Good to know: whether Liberty meets the legal requirements of your business – such as data protection or professional secrecy – is for you to check. No independent external security audit has taken place so far.
The path of a message
The relay is a transport route – not a message store
Your message belongs to you and the person you're talking to. In between, nobody sees anything but encrypted data.
Your device
Encrypt
The message is encrypted locally on your device before it leaves it.
Swiss relay
Pass through only
Passes the encrypted data on exclusively in RAM – nothing ever lands on a disk.
Your contact's device
Decrypt
Only here does the message become readable again – for the intended recipient only.
What Liberty deliberately does not collect
- no phone number as account identity
- no email address as account identity
- no central address book of all your contacts
- not a single message on a server disk
To be honest: Liberty is not a “connection without a server”. The Swiss relay is part of the transport route. But it stores absolutely nothing: every message is passed through end-to-end encrypted, exclusively in RAM.
The heart of it
RAM only.
RAM only.
Never on disk.
The Liberty relay passes things through – it doesn't store them. Your messages flow through its memory encrypted – and are gone again. No archive, no copy, no database full of chats.
- Encrypted in, encrypted out. Even in memory, the server never sees plain text – only unreadable data packets.
- Nothing to grab. What never lands on a disk can't be stolen, analysed or demanded from there.
- Nothing left behind. Once forwarded, no copy of your message remains on the server.
Fewer linkable traces
Protection beyond the content
Encryption protects what you write. Beyond that, Liberty reveals as little as possible about who you write to: there is no phone number, every chat runs over its own route, and the relay does not store who writes to whom.
Separate routes per contact
Each contact uses its own receiving route. Not every relationship runs through the same address.
Outbound and return separated
In 1:1 chats, both directions are handled separately. One route can't simply be derived from the other. In groups, each member has their own receiving route.
No social profile
The relay knows neither names nor phone numbers. What it briefly needs in memory for delivery, it never writes down anywhere.
Local contacts
Contact details and private keys stay on your device – no central address book.
No false promises: metadata protection does not mean total invisibility. Internet connections can reveal technical traces such as connection times or data volumes. Liberty reduces unnecessary central identity and relationship data, but does not promise absolute anonymity.
In everyday use
Feels like a modern messenger
Security works in the background. In the foreground is everything you need day to day.
One-to-one chats
Private conversations with replies, forwarding, editing and deleting.
Group chats
With roles, invitations, replies, forwarding and two subgroup levels for structured conversations. Optionally, a separate comment subchat for every post. Up to 5000 members per group.
Search & bookmarks
Local search in chats and message bookmarks – no search index on a server.
Favourites, archive & mute
Sort, prioritise, archive or selectively mute chats.
“Saved”
Your own storage space for notes and forwarded content – stored only locally on your device.
Status & read receipts
You control online status, read receipts and time information.
Profile pictures per chat
Manage profile pictures in picture groups and choose the right one for each chat.
Protected picture sharing
Only the picture chosen for a given chat is shared, in protected form. Your picture groups stay private.
Chat design just for you
Your own contact logo and background image for every chat – visible only on your device.
Device lost? Contact stays.
If your chat partner has lost their device, you simply restore the connection together. Contact and chat history are preserved.
Lock screen
One click or a keyboard shortcut hides Liberty instantly – new messages keep arriving anyway.
Broadcast messages
Official, digitally signed notices from the Liberty operator, for example about new versions. One-way announcements – no chat, no spam.
Contacts aren't found via phone numbers but connected deliberately via invitations, QR codes or exchanged contact information.
More than text
3 GBper file – transferred encrypted
Files, pictures, videos and voice messages
Media travel over their own protected data channel. That keeps message traffic lean and even large transfers manageable.
Large files
Up to 3 GB – without loading the entire file into memory.
Pictures & videos
Pick them right in the chat and send them encrypted.
Voice messages
Record, listen before sending, then transfer securely.
Pause & resume
Connection dropped? The transfer continues instead of starting over.
Under the hood
Proven cryptography, not home-made
Liberty relies on established, openly documented methods – for one-to-one chats, groups, transport and even its own updates.
Forward secrecy in every one-to-one chat
New keys are derived for every message. Always on – there is no switch to turn it off.
Modern group encryption
Groups use Messaging Layer Security, implemented with OpenMLS. Anyone who leaves the group does not receive the new group keys.
Additionally protected transport
The already end-to-end encrypted data additionally travels to the relay over TLS 1.3.
Text and attachments separated
Messages and large attachments use separate transfer routes – for clarity and stability.
Signed updates
Liberty only installs updates whose signature and checksum are correct. Tampered files are rejected.
Protected locally, too
Chats and keys are stored encrypted on your device – protected by your login password or, in device mode, by Windows.
No independent external security audit of Liberty has taken place so far.
Protection and recovery
You decide where your data lives
No Liberty cloud, no automatic third-party storage. Storage location, backup route and passwords stay under your control.
Emergency code & login password
An emergency code permanently secures recovery. For everyday use, you can choose your own login password.
Device-protected access
On supported devices, access can be bound to the device's own security mechanism.
Automatic backup
Back up chats regularly to a destination of your choice – at times you set.
Portable .lbackup file
Export selected chats password-protected and import them again later.
Backups stay encrypted
Chat backups are never stored as plain text – not even on your own drive.
In 8 languages
Liberty and its installer speak German, English, French, Italian, Spanish, Portuguese, Greek and Russian.
FAQ
Good to know
Do I need a phone number or email address?
No. Liberty needs neither a phone number nor an email address nor a home address. You connect with contacts via invitations, QR codes or exchanged contact information.
Are my messages stored on a server?
No – absolutely nothing. There is no copy of your messages on the server, neither on a disk nor in a database. The Swiss relay passes everything through exclusively in RAM, and even there only in encrypted form. Your chat histories are stored encrypted on your own devices.
Can the relay read my messages?
No. Messages and media are encrypted on your device and only decrypted by the recipient. The relay only ever sees encrypted data.
Am I anonymous with Liberty?
Liberty avoids unnecessary identity and relationship data as far as possible. However, it does not promise total invisibility: internet connections can leave technical traces such as connection times or data volumes.
What happens if my device breaks?
You can restore your chats from the automatic backup or a portable .lbackup file. Because Liberty makes no cloud copy, you are responsible for your own backups – and Liberty helps you with that.
Why does Windows show a warning during installation?
The installer is currently not signed with a paid Windows code-signing certificate, so Windows shows “Unknown publisher”. Download Liberty only from this website. Liberty verifies later updates itself using its own digital signature.
When will Android and Linux be available?
Both versions are in preparation. As soon as they are available, you'll find them on the download page.
Where can I get help?

Does Liberty contain plugins or AI bots?
No. Liberty contains no plugins and no AI bots.
