Overview
Signal is an encrypted messaging and calling app developed by the non-profit Signal Foundation. It is widely regarded as the gold standard for private communication — all messages, calls, and media are end-to-end encrypted by default, meaning that even Signal itself cannot read your messages. Signal does not collect user data, does not serve advertising, and is used by journalists, activists, lawyers, and privacy-conscious individuals around the world. It is fundamentally different in purpose and design from commercial messaging apps like WhatsApp or Snapchat.
How children use it
Teenagers often adopt Signal either because they have privacy-conscious friends or family who use it, or because they are seeking a messaging platform that parents cannot monitor. Some teenagers use Signal specifically to have conversations they do not want parents to see. Signal is also increasingly used in educational and advocacy contexts where privacy is important.
Main risks
Recommended privacy settings
Note to Self / Screen Lock
Location: Settings → Privacy → Screen Lock
Set to: Discuss with your child
Signal supports screen lock via device biometrics. This prevents others from reading messages if they access the device. Discuss with your child whether this is appropriate for their age and your family's approach to privacy.
Disappearing Messages
Location: Conversation settings → Disappearing Messages
Set to: Be aware this feature exists
Signal supports disappearing messages that automatically delete after a set period. While this is a privacy feature for legitimate use, parents should be aware that it can be used to delete concerning conversations.
Note-to-Self Usage
Location: Signal app
Set to: Signal can be used as a private, encrypted notes app — a legitimate use
Signal includes a 'Note to Self' feature that lets users send messages to themselves as private, encrypted notes. This is a legitimately useful feature and not a safeguarding concern in itself.
Parent actions
Have an open conversation about why your child is using Signal and what they use it for — approach with curiosity rather than accusation
Time: 20 minutes
Explain to your child that you respect their privacy and that Signal is a good privacy tool — while also being clear about what conversations you expect to be able to have with them if you are concerned
Time: 15 minutes
Be aware that you cannot monitor Signal messages through parental control software — your relationship and communication with your child is your primary safeguard
Time: Ongoing
