Privacy you choose, message by message
Layergram encrypts selected messages on your device before you share them through WhatsApp, Telegram or other compatible chats. You and your recipient install the app, exchange identities and verify them. Core protection is free and needs no Layergram account. Metadata, compromised devices and copies made by the recipient remain outside this protection.
Start free. Choose one person. Invite them in a few steps.
Only the ones you do not want to entrust to the rest of the chat.
A password, a private thought, a personal plan, or a work-related piece of information may deserve separate protection before being shared. Layergram lets you choose which texts to encrypt for a verified recipient. It does not replace all conversations and does not eliminate risks from devices, the recipient's copies, or chat metadata.
A password. A private thought. A plan that is not ready yet. Work information meant for just two people.
Layergram creates a separate layer for what deserves more care.
For what you would say only to one chosen person.
VALUEFor words, ideas and memories you do not want to lose in the noise of everyday chat.
CONFIDENTIALITYFor credentials, client data and professional information that should not be left in plain text.
New · System keyboard
The Layergram system keyboard lets you compose and decrypt text in compatible chats on iOS and Android. Choose the verified contact, compose the message, and insert the encrypted result into the chat field. You must then press the send button of the messaging app. The keyboard remains optional compared with the in-app flow.
Choose your verified contact and compose your text in the Layergram keyboard editor.
The keyboard inserts encrypted text into the chat input. Then press the send button in your messaging app.
Copy an incoming message and open it in the Layergram editor, keeping the plaintext out of the chat.
Android APK available now. Store updates are being prepared.

The conversation stays in your usual chat app. Only the keyboard is Layergram.
Illustrative demo. No text is sent.
Independent demo. Trademarks belong to their respective owners.
If enabled, reopen the keyboard with Face ID or your phone’s biometrics after the session expires.
A separate layer, not another network
Both of you install Layergram, create an identity, and verify the other person's identity. Write the text in the Layergram app or keyboard and encrypt it for the chosen contact. Share the result in the compatible chat: the recipient opens and decrypts it on their own device. The chat only carries the message; it does not replace identity verification.
How it worksCompose what you want to protect in a space separate from the transport chat, secured with biometrics and screen-capture protection.
Your text becomes encrypted content. Share it directly or inside a cover message—the only text everyone else will be able to read.
WhatsApp, Telegram, Signal, iMessage, email or another compatible text channel, such as some social networks.
The other person’s Layergram identity, stored locally on their device, decrypts the secret content for them to read.
A person is unlikely to recognize that the message contains hidden text. And in any case, they will not be able to decrypt it unless it is intended for their Layergram identity.

You can start with just one person you want to exchange confidential messages with. Both of you create Layergram identities, exchange them, and verify them; then you choose, message by message, when to protect the content before sharing it in your usual chat. Trust in the recipient and the security of your devices remain necessary even after verification.
Your choice is used only to prepare a more natural invitation. It is neither sent nor saved.
I chose you to try Layergram with me. I would like to use it for the messages we prefer to keep truly between us, without changing the chat we already use. It is free: install it, create your identity, send it to me once, and let’s verify it together with mine.
Open core
Layergram's essential protection is free and does not require an account. Premium adds conveniences such as an in-app keyboard, multiple local identities, folders, and encrypted backup, supporting independent development. The Premium in-app keyboard is distinct from the iOS or Android system keyboard. These additional features do not remove limits related to devices, recipients, and transport.
*on devices that support a local large language model
PremiumLMF v3 / post-quantum
Layergram Message Format v3 uses a hybrid approach to reduce the risk that content encrypted and stored today will be attacked later with future tools. Identity and conversation setup combine X25519 and ML-KEM-768. Protection depends on the implementation and the complete model; post-quantum does not mean unbreakable and does not solve device compromise.
LMF v3TechnologyLayergram UI
When you choose cover in the app, the transport chat shows the visible cover text. The verified recipient opens the protected content in Layergram during transport. The outward appearance does not guarantee that a technical analysis will not detect hidden content, and it does not prevent the recipient from keeping copies after reading it on their own device.
Quick GuideHuman channel
In Layergram you can compose certain thoughts to protect before they enter the chat's ordinary flow. This is a choice about the content and the recipient, not a guarantee that every external system will stop observing the conversation. Compromised devices, copies held by the recipient, and channel metadata remain part of the risk model.
A conversation that stays human.FAQ
For a protected exchange, both people use Layergram, import their identities, and verify them. Essential protection is free; the system keyboard is optional, and the in-app flow remains available. The FAQs explain these requirements further and distinguish text encryption from risks related to devices, recipients, and chat metadata.
No. You can start with just one person and use Layergram only when it matters. You both need a verified Layergram identity, a simple process you complete only once.
You can restore your identity with a 24-word recovery phrase. Guard it as carefully as the recovery phrase for a crypto wallet. You can use the same identity on more than one device, but messages are not synchronized: decrypting a message on one device will not make it appear automatically in the same chat on another.
A chat's end-to-end encryption protects messages as they travel between devices. Layergram adds a separate layer for content you compose and encrypt locally before handing it to the chat. It does not turn on or replace encryption in WhatsApp or another app. Contacts, timing, devices and the recipient's actions still matter.
It encrypts the content you choose. It does not archive or hide WhatsApp chats, control notifications or erase metadata. In the app, a cover message can make protected text less conspicuous, without making it undetectable. The system keyboard inserts encrypted text instead.
When enabled, Layergram uses the protections offered by the platform. Android can block screen capture more directly; other systems have different limits. An external camera or a compromised device is, of course, beyond its reach.
No. Core protection remains free. Premium adds convenience, organization and encrypted backup, supporting independent development.
Yes, in Premium versions on supported platforms. It uses a separate 24-word phrase, distinct from your identity recovery phrase; availability and provider depend on the installed platform.
Start free
To start, you and the chosen person install Layergram, create your identities, exchange them, and verify them. Then you compose a message in the app and share the encrypted result in the compatible chat you already use. The recipient decrypts it on their own device. Essential protection is free and does not require a Layergram account.
