Privacy

You don't need to sign up. There are no usernames, passwords or profiles in Kasper. Two phones are paired with a temporary room code.

For the phones to find each other, a short room code and a signaling service are used. The room code and related connection info is only active while the room is in use, and is removed automatically afterwards.

Audio and video are sent directly between your two phones (peer-to-peer via WebRTC). The stream does not pass through our servers and is not recorded or stored by Kasper.

Motion and noise detection happen locally on the baby phone. Only small events (like "noise detected" or "low battery") are sent to the parent phone so it can alert you.

The log of events and sleep patterns is stored locally on the parent phone (in the browser). It doesn't leave the phone and can be deleted by clearing browser data.

Kasper doesn't use marketing cookies and has no third-party tracking or ads. No personal data about the child is collected.

You can end a room at any time, clear the log by clearing browser data, or stop using the app. There is no account to delete, because none is created.
