User intervention based on proximity between tracking devices

A non-transitory computer-readable storage medium storing executable instructions that, when executed by a processor, cause the processor to perform steps comprising:

• receiving, at a central tracking system, a first location of a first tracking device from a first mobile device in response to the first mobile device detecting the first tracking device and a second location of a second tracking device from a second mobile device in response to the second mobile device detecting the second tracking device;
• selecting a threshold distance based on historical distances between the first tracking device and the second tracking device at historical dates and times corresponding to a current date and time;
• and
• determining that the second tracking device is lost in response to determining that a distance between the first mobile device and the second mobile device is greater than the threshold distance when the first mobile device detects the first tracking device and the second mobile device detects the second tracking device, and providing a notification to a device of an owner of the second tracking device indicating that the second tracking device may be lost and including a configuration element prompting the owner of the second tracking device to 1) change a rate at which advertisement signals are broadcast by the second tracking device, and 2) indicate if the second tracking device is not lost.
