The private locations Beta in the Uptrends app are a relatively new way to set up checkpoints in your own network.
Until now you would access this feature by going to the menu. From now on you can access private locations directly from the main menu by clicking making it quicker to get to the setup of your own checkpoints.
Note that private locations are a public beta feature. You are welcome to try it out and give your feedback. More information is available in the knowledge base article Beta programs.
