On this site I share why I ask parents to choose Signal over WhatsApp for class groups and how to make that switch. I created this site to answer recurring questions in one place. My concern centres on the amount of data WhatsApp and its owner, Meta, collect about us and our children. Parent groups link us to our children across Meta’s services, building detailed profiles before children ever have a chance to opt in. Signal provides the same core messaging with much better privacy, in exchange for slightly less convenience.
