Can my employer — or Syncer — read my clipboard?

No. Clips are encrypted on your device before they're sent, so nobody on the network path — Syncer, your ISP, your employer's network, or anyone sniffing the wire — can read them. Only your own paired devices hold the keys.

Does clipboard sync work between iPhone and Windows, or Android and Mac?

Yes. iPhone to Windows, Android to Mac, Linux to iPhone — any combination. Desktop to phone is automatic; an iPhone copy syncs out the moment you open Syncer or its keyboard, because iOS doesn't allow background clipboard reading.

How fast is Syncer clipboard sync?

Real-time. It rides a live connection rather than a slow poll, so it's usually waiting on your other device by the time you switch to it.

Will Syncer drain my battery?

Negligibly. Syncer only does work when your clipboard actually changes, and the keyboard uses a pre-warmed lightweight engine instead of booting the whole app.

Syncer — Cross-platform clipboard manager. Copy on any device, paste from your phone's keyboard.

Where Syncer is different

Your clipboard, on your phone's keyboard.

Most clipboard tools stop at the desktop. Syncer's keyboard works across the apps you type in every day — so whatever you copied on your laptop is one tap away, right where you're typing. No app-switching. No "let me send this to myself." Just paste and move on.

Clipboard history

Your recent clipboard, searchable.

Your synced clips are searchable and organized. That command from this morning, the invoice number from Tuesday, the address from last week — search, find, paste. It's all on-device and encrypted, and it expires on your schedule.

Try it — type in the search and watch it filter. Every clip is on-device and encrypted.

Keeps 7 days of searchable history — all on your device.

Security

Your clipboard is encrypted
before it leaves your device.

We relay encrypted data. We never see what's inside. Every synced clip is sealed on your device with a key only your own devices hold — we use the Signal Protocol to pair and verify those devices, never to read your clipboard.

Encrypted on-device, alwaysClips are sealed before they're sent. Our servers only ever handle ciphertext.
No tracking, no ads, no resaleWe don't log what you copy or build a profile. There's nothing to sell.
Verify devices, revoke instantlyCompare a safety fingerprint to verify a new device, protect approvals with biometrics, and cut any device's access with one tap.

Syncer vs. the clipboard tools you've tried

Some sync within one ecosystem. Some never leave the desktop. Among these, only Syncer spans all five platforms.

Why I built this

I kept emailing myself links. Typing 2FA codes by hand off my laptop screen. Losing that one command somewhere between my Mac and a server. Everything I tried either stayed inside one ecosystem or left one of my devices behind.

It annoyed me enough that I finally built the fix — one clipboard that follows me across my devices, and doesn't read my data on the way. If that sounds like your day too, you'll get it.

The questions you're actually asking

Can my employer — or you — read my clipboard?

Not in transit. Clips are encrypted on your device before they're sent, so nobody on the network path — us, your ISP, your employer's network, anyone sniffing the wire — can read them. Only your own paired devices hold the keys. (One honest caveat: no app can protect a device that's already compromised. Software running on the machine itself — corporate monitoring, device-management agents, malware — sees your clipboard before any app encrypts it. That's true of every app on that device, not just Syncer.)

Does it actually work between iPhone and Windows (or Android and Mac)?

Yes — that's the entire point. iPhone ↔ Windows, Android ↔ Mac, Linux ↔ iPhone, any combination; Syncer doesn't care which ecosystems your devices come from. Desktop → phone is automatic. One nuance: an iPhone copy syncs out the moment you open Syncer or its keyboard — iOS doesn't allow background clipboard reading, so that one direction takes a tap.

How fast is it?

Real-time. It rides a live connection rather than a slow poll, so in practice it's usually waiting on your other device by the time you switch to it.

What happens to passwords and 2FA codes?

Passwords and anything your OS or password manager marks sensitive are never synced at all — they stay on the device you copied them on. (Auto-expiring one-time codes, so they don't linger in your history, is a planned feature.)

Do I need an account?

Yes — a lightweight one. A quick email sign-in verifies which devices are yours and pairs them together, so only your own verified devices can sync and read your clips. No password to remember, and the account never gives Syncer the ability to read your clipboard.
