End-to-end encryption

End-to-end encryption (E2EE) means data is encrypted on your device and can only be decrypted by you — the service storing it never has access to the readable content.

What it means

With end-to-end encryption, your content is scrambled on your own device before it is sent anywhere. Only you hold the key to unscramble it. The company running the service stores ciphertext — data it cannot read.

How it works

Your device encrypts the data locally. The encrypted blob travels to the server and is stored as-is. When you want to read it, your device decrypts it with a key only you control. The server never sees the key or the plaintext.

Why it matters

Most cloud services can read your data — and so can anyone who compromises them or compels them legally. End-to-end encryption removes that risk: there is nothing readable to hand over, leak, or mine.

How Atomic Blend uses it

Every note, task, calendar event and email in Atomic Blend is encrypted on your device with AGE before it leaves. We only ever store ciphertext.
