File content is encrypted on the sending device before upload.

The little things.
Connected, too.
Links, notes, opt-in clipboard sharing and incoming-call controls. Your everyday essentials, in the same encrypted channel.
All capabilities and requirements
Encrypted file transfer
Send files between Android and desktop with transfer progress and retry. File size, count and retention depend on your plan.
SMS from your desktop
Read incoming Android texts, start conversations and reply from Mac or Windows. Your phone sends the SMS; carrier charges may apply. Mirroring texts sent on the phone is an optional setting.
Notifications that clear both ways
See current Android notifications on desktop, dismiss one from desktop to clear it on your phone, or clear it on your phone to remove it from desktop. Quick-reply works when the source app supports it. This is not notification history.
Incoming-call controls
See who's calling, decline from desktop, or decline with a text. Android call-screening permissions are required. Calls are not answered remotely and call audio stays on your phone.
Clipboard sharing
Share clipboard text between Android and desktop. Desktop sync is opt-in; Android can send its clipboard on demand. Clipboard content is ephemeral and requires both devices online.
Pre-release features, implemented and in testing. SMS, notification and call features depend on Android permissions and platform support. Message and data charges from your carrier may apply.
Private by design
Pair once.
Keep it between you.
Scan your desktop's QR code with Android, or use the full pairing token. No account required. Enable only the Android permissions for the features you want.
Content is encrypted on your devices before it reaches the relay. The pairing invite shares your channel key, so keep it private.
Encryption protects content passing through the relay, not a compromised device or a shared pairing invite. Routing metadata remains visible to the service; catch-up history is limited, not a permanent backup.
How encryption and retention work
Device-generated channel key
A random 256-bit key is shared through the pairing QR code or full token, not through the relay. Anyone holding that invite has the key, so keep it private.
AES-256-GCM
Clients encrypt message content before sending it, using authenticated encryption with a 12-byte nonce and 128-bit tag. Paired devices use the shared channel key to decrypt it.
Encrypted content, visible metadata
The relay handles encrypted message bodies, but can see identifiers, message kinds, timestamps and sizes. Delivery receipts and message-deletion IDs are not encrypted.
Limited relay retention
Encrypted messages can remain in relay history after delivery, until retention or message limits remove them. Reconnect catch-up is not a permanent backup. Paired devices can keep local history.
Planned launch pricing

A few things to know.
When can I download it?
Android + Mac is being prepared for release. The native Windows client is in testing; a public Windows beta is not available yet. We have not announced a release date. The launch list sends announcements and invitations, not an immediate download or a guaranteed place in a beta.
What about iPhone or a browser extension?
iPhone, iPad and browser extensions are not available. The website demo is an illustration, not a browser client. More platforms are being explored, not promised.
What counts as a device?
A device slot is a paired app installation in your channel, not an email account or a browser tab. Free has room for a phone and a computer. A separate installation can occupy another slot; unpair devices you no longer use before adding replacements.
Does my phone still send texts and handle calls?
Yes. Your paired Android sends SMS; carrier charges may apply. Desktop call controls let you see or decline incoming calls, not answer them remotely. Call audio stays on your phone. These features require the relevant Android permissions.
