Kasane layers everything you copy — text, links, passwords, images — ready to search anytime and synced with end-to-end encryption across all your devices.
iOS · Android · macOS · Windows
Designed to disappear until the exact moment you need it.
Not a feature list — the situations where Kasane actually saves you.
2FA codes, Wi-Fi passwords, an address, a link — stop messaging them to yourself. Whatever you copy on one device is ready to grab on every other one, encrypted end-to-end like a password manager.
Grab a run of IDs, fields or lines from a sheet or doc, switch windows once, then hit ⌘V again and again — every paste serves up the next clip in order. No more bouncing between windows for each one.
The Excel unlock password your next copy overwrote, a half-written draft, last week’s link, a line of text inside a screenshot — full-text and OCR search dig it out in milliseconds. Big clips never lost, never laggy.
Did you know? Almost any app on your machine can read — and change — your clipboard. An attack can quietly swap the blockchain address you copied for the attacker’s own. Kasane detects abnormal clipboard changes and warns you, and can auto-clear the clipboard so sensitive data never lingers there.
Start free. Upgrade when your clipboard does.
Your clips live locally on your device. When Pro sync is enabled, they are encrypted end-to-end before they ever leave your device.
Encryption keys never leave your devices. We cannot read your clips — and neither can anyone else.
We collect anonymous usage statistics only, never clip contents. You can opt out anytime in Settings.
End-to-end encryption has no back door: if you forget your password and lose access to your account, your encrypted data cannot be recovered by anyone — including us — and is permanently lost. Please keep your credentials safe.
Export or permanently erase all of your data at any time from Settings → Account.
This is the core function of the app. Clipboard data stays on your device and is visible only to you — our servers cannot read it.
On mobile, the Kasane Keyboard requests full access so you can browse and paste your clipboard directly from the keyboard.
Used only when you choose to upload an image or set a profile picture.
Kasane apps are provided under a personal, non-transferable license for use on your own devices.
Pro renews automatically at $7.99 / quarter or $19.99 / year. Actual prices may vary slightly by platform and region. Cancel anytime via the App Store or Google Play; cancellation takes effect at the end of the current period.
Do not reverse-engineer, resell, or use Kasane to violate laws or the rights of others.
Kasane is provided "as is", without warranties of any kind. You are responsible for safeguarding your account credentials. Due to end-to-end encryption, data that becomes inaccessible through lost or forgotten credentials cannot be restored, and Nazo KK assumes no responsibility for such loss or for any indirect or consequential damages.
