[AC Question]

This app is using 6Gb data storage and I keep getting messages that storage is full. What is it doing and how can I reduce data usage within it? Can't uninstall or clear data as those options are greyed out. Samsung Galaxy S5. Help is much appreciated.

Internet Protocol Security (IPsec) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host).[1]
