Watch your home from anywhere. Without trusting anyone with the footage.

How it works
Three steps, one principle: the plaintext never leaves your phone. Anyone in the middle only ever sees scrambled bytes.
Your old phone, watching
Plug in a spare Android phone, prop it up, and let the app run. No cameras to buy, no smart-home account to create.
Locked on the device
Every frame is encrypted on the phone before it touches the network. The key never leaves your device.
Open in any browser
Sign in here from anywhere and the stream is decrypted right in your browser, never on our servers.

How the privacy holds
Each guarantee below follows from the architecture, not policy.
Your cloud sees scrambled bytes
Recorded videos are encrypted on the phone before upload. The cloud provider (Drive, Nextcloud, any WebDAV) only ever stores opaque blobs that no one else can read.
Keys never leave the device
Your encryption keys live on the phone, locked behind your password. Lose the password and even we can't recover your footage. That's the whole point.
No analytics, no trackers
This page makes zero third-party requests. No Google Fonts, no analytics scripts, no ads. Go ahead and check the network tab.
Under the hood (for the curious)
Recordings are encrypted with AES-256-GCM in 64 KB chunks
(file magic ATLB).
The per-video key is wrapped with a hybrid post-quantum KEM that
combines X25519 and ML-KEM-768. Secure if either one stands.
The browser viewer decrypts recordings with the same handshake — no key ever leaves your device.
