A method for locating a tracking device owned by a user and attached to or enclosed within an object the user wants to track, comprising: accessing, by a tracking system , a set of safe conditions associated with the tracking device , the set of safe conditions defining a geographic boundary and further comprising a time window; receiving, by the tracking system from a first mobile device within range of the communication capabilities of the tracking device , a location of the tracking device ; determining, by the tracking system , that the tracking device is safe if a probability that the tracking device is located within the geographic boundary during the time window is higher than a threshold probability, wherein the tracking device has a lower probability of being within the geographic boundary during the time window the greater the distance from the geographic boundary and the greater the difference in time between the current time and the time window; determining that the tracking device is not safe if the probability is lower than the threshold probability; in response to determining that the tracking device is not safe: generating, by the tracking system , a notification indicating that the safe conditions are not satisfied; and sending, by the tracking system , the generated notification to a second mobile device associated with the user , the second mobile device configured to display the notification, and wherein the first mobile device and the second mobile device are communicatively coupled to the tracking system . accessing, by a tracking system , a set of safe conditions associated with the tracking device , the set of safe conditions defining a geographic boundary and further comprising a time window; receiving, by the tracking system from a first mobile device within range of the communication capabilities of the tracking device , a location of the tracking device ; determining, by the tracking system , that the tracking device is safe if a probability that the tracking device is located within the geographic boundary during the time window is higher than a threshold probability, wherein the tracking device has a lower probability of being within the geographic boundary during the time window the greater the distance from the geographic boundary and the greater the difference in time between the current time and the time window; determining that the tracking device is not safe if the probability is lower than the threshold probability; in response to determining that the tracking device is not safe: generating, by the tracking system , a notification indicating that the safe conditions are not satisfied; and sending, by the tracking system , the generated notification to a second mobile device associated with the user , the second mobile device configured to display the notification, and generating, by the tracking system , a notification indicating that the safe conditions are not satisfied; and sending, by the tracking system , the generated notification to a second mobile device associated with the user , the second mobile device configured to display the notification, and wherein the first mobile device and the second mobile device are communicatively coupled to the tracking system . <EOS>
