How It Works

Up and running in minutes

Three steps to seamless clipboard sync between your Mac and Android.

1

Install on both devices

Download ClipRelay on your Mac and install from Google Play on Android.

2

Scan QR code to pair

Open both apps and scan the pairing QR code. Encryption keys are exchanged securely.

3

Clipboard syncs automatically

Copy on one device, paste on the other. It just works — no cloud, no accounts.

Features

Privacy-first clipboard sync

Built from the ground up to keep your data off the cloud and on your devices.

Automatic Mac → Android Sync

Copy on your Mac and it appears on your Android instantly. No buttons to press, no extra steps.

No Cloud, No Servers

Your clipboard data never leaves the direct connection between your devices. Zero servers, zero accounts, zero tracking.

Direct Bluetooth Transfer

Your data travels straight from one device to the other over Bluetooth Low Energy — no WiFi or internet needed. Works anywhere, even offline.

AES-256-GCM Encryption

Every transfer is encrypted with AES-256-GCM. Keys are exchanged during pairing and never leave your devices.

Near-Zero Permissions

The Android app only requests Bluetooth Low Energy — no internet, no location, no storage access. The Mac app runs fully sandboxed with Bluetooth as its sole entitlement.

Source Available

ClipRelay's source code is publicly available. Review every line, verify our security claims, or inspect the encryption yourself on GitHub.

Image Sync (experimental)

Transfer images (PNG & JPEG, up to 10 MB) between devices. Uses a temporary local WiFi connection for speed, with BLE for signaling — still fully encrypted, still no cloud.

Auto-Copy on Android (experimental)

Automatically detects when you copy text on Android and syncs it to your Mac — no manual sharing required. Enable it in the app settings.

FAQ

Frequently asked questions

Is my clipboard data sent to any servers?
No. ClipRelay uses Bluetooth Low Energy (BLE) for a direct device-to-device connection. Your clipboard data never touches a server, cloud service, or the internet. It goes straight from one device to the other.
How secure is the encryption?
ClipRelay uses AES-256-GCM encryption — the same standard used by banks and governments. Encryption keys are exchanged during the QR code pairing process and are stored locally on your devices. They are never transmitted or stored elsewhere.
Is my data secure over Bluetooth?

ClipRelay encrypts all data with AES-256-GCM before it ever leaves your device. Bluetooth Low Energy is just the transport — by the time anything hits the airwaves, it's already ciphertext.

This is the same design pattern used throughout the industry. Smart locks like August and Yale authenticate over BLE using their own cryptographic protocols on top. Continuous glucose monitors transmit patient health data over BLE with application-layer encryption. The principle is the same: treat BLE as a pipe, secure the contents independently.

Even in the unlikely event someone intercepts your BLE traffic, they get encrypted bytes with no way to derive the key.

What is the range?
BLE typically works within 10-15 meters (30-50 feet) depending on your environment and devices. It works best when devices are in the same room, which is the typical use case for clipboard sharing.
What types of content can I sync?
ClipRelay syncs plain text (URLs, code snippets, passwords, addresses, etc.) over Bluetooth. With the experimental Image Sync feature enabled, you can also transfer images (PNG & JPEG, up to 10 MB) — these are sent over a temporary local WiFi connection for speed, while BLE handles the signaling. Both devices need to be on the same WiFi network for image transfers.
Does it work without WiFi?
Yes! Text clipboard sync uses Bluetooth Low Energy, which is completely independent of WiFi and cellular data. It works in airplane mode, offline, or anywhere — as long as Bluetooth is enabled on both devices. The experimental Image Sync feature does require both devices to be on the same WiFi network for the actual image transfer.
What are the system requirements?
macOS 13 (Ventura) or later, and Android 11 or later. Both devices need Bluetooth Low Energy support, which is standard on all modern Macs and Android devices.
What permissions does ClipRelay need?
Almost none. The Android app requests Bluetooth Low Energy and notification permissions. If you enable the experimental Auto-Copy feature, it also needs the Accessibility Service permission to detect copy actions. If you enable Image Sync, local network access is used for the image transfer. The Mac app runs in Apple's App Sandbox with Bluetooth and local network as its entitlements. ClipRelay asks for the bare minimum needed to sync your clipboard.
Is ClipRelay free?
Yes, ClipRelay is completely free. There are no ads, subscriptions, or hidden fees.
