Privacy policy

Bercio links two of your phones to watch over your baby: one stays in the nursery (baby device), the other goes with you (parent device).

Picture and sound travel directly from one phone to the other, encrypted. The publisher does not receive them, does not record them and has no access to them. No account is required.

The app is free, funded by a Google AdMob banner ad shown on the parent device only.

On the baby device, the camera and microphone film and listen to the nursery while monitoring. The stream is sent live, end-to-end encrypted (WebRTC, DTLS-SRTP), only to the parent devices you have paired. Nothing is recorded.

On the parent device, the camera is only used to scan the pairing QR code, and the microphone for the “Talk” button, while you hold it.

Cry recognition (Google's YAMNet model, run by MediaPipe), noise detection and motion detection work on the baby device, offline. Only results are sent to the parent device: sound level, scores for crying, babbling or laughter, motion score. Never the analysed audio.

For your two phones to find each other over the Internet, the app relies on third-party services. They receive neither your name, nor your email address, nor the picture, nor the sound:

• PeerJS Cloud (connection server 0.peerjs.com): receives an identifier derived from the pairing code and each device's IP address, while the connection is set up.
• Google STUN (stun.l.google.com): sees the device's IP address, to tell it its public address.
• PeerJS TURN relay (eu-0.turn.peerjs.com, us-0.turn.peerjs.com): when a direct connection is impossible, the stream goes through this relay. It stays end-to-end encrypted: the relay can neither see nor hear it.

The banner ad is served by Google AdMob, on the parent device only, never on the baby device. To serve it, Google processes:

• the device's advertising identifier;
• the IP address and the approximate location derived from it;
• interactions with the ads and diagnostic information.

In the European Economic Area, the United Kingdom and Switzerland, a form asks for your consent to personalised advertising. You can review your choices at any time: Settings, “Manage ad choices”. On iOS, the app also asks for tracking permission (App Tracking Transparency); without it, ads are not personalised.

Ads are silent and limited to content suitable for most audiences with parental guidance.

The “Take a photo” button on the parent device captures the current picture. It stays on the phone, in a temporary folder of the app, until you share or save it through the phone's share menu. It is never sent to the publisher.

The app keeps on each phone, and nowhere else:

• your settings (language, sensitivity, video quality, theme…);
• on the baby device, its pairing code, the room name and the identifiers of the accepted parent devices;
• on the parent device, the paired rooms and the night journal (crying, movement, noise and outages over the last 14 nights).

• Camera and microphone: monitoring, the QR code, the “Talk” button.
• Notifications: the alerts (crying, movement, noise, low battery, lost connection), created on the phone itself; on Android, the ongoing notification of screen-off monitoring.
• Photos (iOS, add only): saving a photo when you choose to.
• Background: keeping the baby's sound playing when the parent device's screen is off.

The publisher runs no server that would receive your data: no account, no name, no email address, no usage statistics, no picture and no sound. Pictures of your child are only seen by the devices you have paired.

Bercio is meant for adults; it is not intended to be used by children.

• The night journal only keeps the last 14 nights; “Clear journal” empties it at once.
• “New code”, on the baby device, forgets every paired parent device.
• Uninstalling the app, or clearing its data in the phone's settings, deletes everything it kept.
• Data processed by Google for advertising follows Google's policies; the advertising identifier can be reset in the phone's settings.

You have the rights of access, rectification, erasure, restriction, objection and portability. As the publisher holds no data about you, these rights are exercised directly on your phone (see above) and, for advertising, with Google. For any question: support@tequi.app.

You may also lodge a complaint with the CNIL, the French data protection authority: https://www.cnil.fr

This policy may change with the app. The date of its last update is shown below; the version in force is always published in the app and on its website.
