Yes, if your parents have access to the WiFi router's admin panel, they can potentially see some information about your online activities, including the apps you use on your phone. Here's what you need to know:

1. Router Logs: Most modern routers keep logs of connected devices, event timestamps, bandwidth usage, visited website URLs, and IP addresses [2]. Network admins can view this information through the router management's back-end. While the logs may not provide detailed information about specific app usage, they can give a general idea of the websites and services you access.

2. Analysis Software: In some cases, WiFi owners could use analysis software like WireShark and OpenDNS to gain more detailed insights into your online activities, including the apps you use and even the texts you send [2].

3. Encryption: If you use apps that have built-in encryption or use a VPN (Virtual Private Network) app, your online activities can be protected from prying eyes on the WiFi network. Encryption ensures that your data is secure and cannot be easily intercepted or monitored [1].

4. Public WiFi: When using public WiFi networks, such as those in cafes or airports, it's important to be even more cautious. Public WiFi providers may record and sell your information to advertisers, making your data more vulnerable [2].

It's worth noting that while it is technically possible for parents or WiFi owners to see some information about your online activities, it is important to have open and honest communication with your parents about privacy concerns. Respecting each other's boundaries and discussing expectations can help create a healthy digital environment.
