Pair Your Devices
Pair supported Core clients with a QR code. Device-first pairing keeps key material on the clients; browser and account features require sign-in.
- Device-first QR pairing
- Supported Core clients
- Verified native releases only
Your stuff. Your devices. Encrypted.
Pair your iPhone with any computer. Send clips, file bytes, and screenshots with end-to-end encryption, so the relay cannot decrypt their contents.
Free for 2 devices

Send Anything
Clips, files, screenshots, links — send them between your devices with one action. Free up to 25MB, 100MB on Pro.
- Text, files, images, links
- Drag-and-drop or hotkey
- Large file support (Pro)
Encrypted by Default
Clipboard bodies and transferred file bytes are encrypted before they leave your device. The server relays ciphertext and cannot decrypt these payloads.
- Zero-knowledge architecture
- Keys stay on your devices
- Server cannot decrypt
Tray App + Hotkeys
Verified native clients can live in the system tray or menu bar and expose intentional shortcuts for common actions.
- System tray / menu bar
- Global keyboard shortcuts
- Intentional, not automatic
Encrypted History
Your recent clips and transfers are stored locally with encryption. Search and re-send anything from your history.
- 25 items (Free) / unlimited (Pro)
- Encrypted local storage
- Quick search & re-send
How It Works
Encrypted transfer between supported clients
Open and Connect
Open the authenticated browser companion now. Install a native client only when the download page lists a verified artifact, then connect supported clients.
Sign in → Connect supported client → Verify
Share Your Way
Copy text, send files, or create secure links from screenshots. Quilon keeps flows fast and encrypted.
Copy / Drop / Share Link → Encrypted
Open Anywhere
Open Quilon on your other device to paste instantly, or send a secure link to anyone when needed.

[security.protocols]
Encryption-first architecture, zero-knowledge design
End-to-End Encryption
AES-256-CBC encryption on all clipboard data. Only your devices can decrypt.
No Plaintext Content Payloads
Clipboard bodies and Private Share bytes are client-encrypted and relay-only. Account and routing metadata is still processed by the service.
Zero Knowledge
We don't hold the keys needed to decrypt protected content payloads. Operational metadata remains visible to the service.
