I’ve looked into the idea before, and what really matters is doing it responsibly and with consent, especially when considering a whatsapp tracker,whatsApp itself has features like linked devices and notifications you can set up so you don’t miss messages on multiple devices you own,there are also family safety tools some carriers provide that help keep everyone in the loop without spying on someone,the key is to talk openly with the person you’re trying to help and make sure they’re okay with the setup that way you solve the problem without creating trust issues.
