Short answer: install Syncer on your Android phone and your Windows PC, sign in, and pair them. Anything you copy on Windows shows up on the Syncer keyboard on your phone, and phone copies go to your PC with one tap — end-to-end encrypted the whole way.
The problem
You copy a link, an address or a code on your PC and need it on your phone — or the reverse — and end up emailing or messaging yourself. Microsoft's own option works through Phone Link and the SwiftKey keyboard, which is fine if you already use both. Syncer works with any setup, and keeps the clipboard you sync encrypted end-to-end.
How to sync your clipboard between Android and Windows
- Install Syncer on both devices. Syncer for Android and Syncer for Windows — both free.
- Sign in with the same account on both. A quick email sign-in tells Syncer which devices are yours. No password to remember.
- Pair the second device. Scan the QR code or enter the 6-digit code, then approve it from the first device. You can compare the safety fingerprint on both screens to rule out an impostor.
- Turn on the Syncer keyboard on your Android. The app walks you through adding it. From then on your synced clips sit right on the keyboard in any app — Messages, WhatsApp, Gmail, a browser, a login form.
- Copy on one, paste on the other. That's it — the clip arrives over a live connection, usually before you've switched devices.
Android → computer takes a tap. Android 10 and later stop apps from reading the clipboard in the background, so a copy made on your phone goes out when you tap Sync in Syncer or on the Syncer keyboard. Computer → Android needs nothing: the clip is waiting on the Syncer keyboard.
Text today. Syncer syncs text — links, codes, commands, addresses, notes. Image and screenshot sync is planned, not shipped.
End-to-end encrypted, so we can't read your clipboard
- Sealed on your device. Every clip is encrypted with XChaCha20-Poly1305 under a clipboard key that only your paired devices hold — before it ever leaves the device you copied on.
- Signal-verified pairing. Syncer uses the Signal Protocol to verify each new device and hand your clipboard key over safely. New devices need explicit approval from one you already trust, and you can revoke any device instantly.
- A relay that only sees ciphertext. Our servers pass along sealed blobs they have no key to open, and delete each one the moment your device fetches it. Anything unfetched expires within 7 days.
- Passwords stay put. Passwords and anything your OS or password manager marks sensitive are never synced — they stay on the device you copied them on.
- Backups only you can open. Optional backups are sealed with a key derived from your PIN using Argon2id and encrypted with AES-256-GCM. Your PIN never leaves your device.

Questions
Can I sync my clipboard between Android and Windows?
Yes. Install Syncer on both, sign in with the same account and pair them. Copies on Windows appear on the Syncer keyboard on your Android phone; copies on your phone go to Windows when you tap Sync.
Do I need Phone Link or SwiftKey?
No. Syncer works with its own apps on Windows and Android and doesn't depend on Phone Link or any particular keyboard — though its own keyboard is the fastest way to paste.
Does it work when my phone isn't on the same Wi-Fi as my PC?
Yes. Syncer works over any internet connection — Wi-Fi, mobile data, office network.
