I'm tired of forgetting what pound recoil spring I put in a pistol that I haven't shot in three years and was considering using a firearms inventory log such as Guntrack or Guns Locker to keep track of things. My biggest concern is where the data that I input is stored and possibly who it is sold to. Do any of you cyber security types have any insight or experience with either of these apps? Would these apps be considered "safe and secure" to use? Thank you in advance.
