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. I built a simple, private way to send information that is meant to be read once and then disappear.

Why I 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. I wanted a tool that treats a secret like a secret, encrypted before it leaves your device and deleted the moment it is read.

What I Believe

• Privacy should be the default, not a setting you have to find.
• The less data the site holds, the less there is to lose. So it holds 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 the security page.

Who Writes This

I'm Mor, a web developer, and SneakNote is a solo project. I write the code, run the servers, and write everything you read here. That also means the buck stops with me when something is wrong.

You can see what else I build on GitHub.
