Send something private.

Paste a password or attach a file. You get a link that opens a limited number of times, then the secret is deleted. Corespark can't read it.

Create a secret link

Encrypted in this browser before it is sent. We never see the original.

A second lock. Send it separately from the link, like by phone call or text message.

  • Locked in your browser

    Your text or file is encrypted with AES-256 on your device, before anything is uploaded.

  • The key stays in the link

    It sits after the # in the link, and browsers never send that part to a server.

  • Gone after the last view

    Once it has been opened as many times as you allowed, or its time is up, it is deleted.
