You have no cause for concern with regard to security and privacy of your iPad or its data.
Only WiFi+Cellular models of iPad have GNSS/GPS functionality - this being a function of the iPad Cellular chipset. WiFi Only models of iPad have no GPS capabilities with which iPad Location Services can derive location. This fundamental difference may significantly impact your apparent location or ability to use mapping Apps - in particular if real-time positioning (e.g., a moving map) is required.
WiFi Only models can only “infer” their location from a database lookup of neighbouring WiFi networks for which the geographic location is known, or the geographic location of your public IP address. For static applications in urban locations, where the location of IP public IP addresses and WiFi networks are known, an “inferred” location can be relatively accurate. However, in rural locations, or when using a Cellular/Satellite/VPN connection, location accuracy of an inferred location [if it works at all] may be very inaccurate.
Location derived solely from your public IP Address can be very inaccurate. Due to internal network routing by your Internet Service Provide (ISP), the IP Address used to derive location may be located a significant distance from your actual location.
