How Call Pet Keeps Your Pet Footage Private
Most pet cameras send your video to a company's servers. Call Pet works completely differently — here's exactly what happens when you watch your pet.
The problem with most pet cameras
When you use a typical pet camera — whether a dedicated device or a phone app — your video is uploaded to the company's cloud servers. That means:
- The company's servers receive and relay your video stream
- If their servers are hacked, your footage could be exposed
- The company could technically view your footage
- Your video data is stored on infrastructure you don't control
Peer-to-peer streaming
Call Pet uses WebRTC — the same open technology powering FaceTime, Google Meet, and WhatsApp video calls — to stream video directly between your two phones.
When you open the camera view, your spare phone and your main iPhone establish a direct connection. Video travels from one device to the other — it never passes through Call Pet's servers, and it's never stored anywhere.
Even when a relay is needed to bridge different networks, the video is still end-to-end encrypted — the relay server cannot read the content.
End-to-end encryption
Before any video is transmitted, the two phones perform a cryptographic handshake to establish a private encryption key:
Key exchange (X25519)
Each phone generates a unique private key locally. They exchange only the public halves — mathematically combining them to create a shared secret that only these two devices can know.
Video encryption (AES-GCM)
Every frame of video is encrypted using AES-GCM — the same standard used by HTTPS, banking apps, and TLS 1.3. Even if someone intercepted the stream mid-transit, they would see only scrambled data.
Keys never leave your devices
The encryption keys are generated and stored only on your two phones. Call Pet's servers never see them — the team has no technical ability to decrypt your video.
What Call Pet cannot access
Call Pet collects anonymous crash analytics (app version, device type, crash stack) to fix bugs. No personal information or video content is included.
