Yes, many apps do save the IP address of the devices that access them. This is often done for security and analytical purposes, such as tracking and preventing fraudulent activity, monitoring user behavior, and ensuring the security of the app and its users.

One way to hide the IP address for apps is to use a virtual private network (VPN) service. A VPN creates a secure, encrypted connection to a server, which then masks the user's IP address and replaces it with the server's IP address. This makes it difficult for third parties to track the user's online activities. Another method is to use a proxy server, which acts as an intermediary between the user's device and the internet, hiding the user's IP address from the websites and apps they access. Additionally, using the Tor network can also help to hide the IP address by routing internet traffic through a series of volunteer-operated servers, making it difficult to trace the user's online activities. **
