About SneakNote

SneakNote exists for one reason: sharing a secret should not mean leaving a permanent copy of it in someone's inbox, chat history, or server logs. We built a simple, private way to send information that is meant to be read once and then disappear.

Why We Built It

Every day, people paste passwords into Slack, email API keys to contractors, and text sensitive details that linger long after they are needed. Those copies become a liability the moment an account is compromised. We wanted a tool that treats a secret like a secret, encrypted before it leaves your device and deleted the moment it is read.

What We Believe

• Privacy should be the default, not a setting you have to find.
• The less data we hold, the less there is to lose. So we hold as little as possible.
• Security tools should be honest about what they can and cannot do.
• You should not need an account to send someone a private message.

How It Works

SneakNote encrypts your note in the browser and stores only ciphertext it cannot read. The note self-destructs after it is opened or when its timer expires. You can read the full technical breakdown on our security page.
