A variety of location-based and/or proximity-based features related to diabetes management systems can be used to improve maintenance compliance and/or to provide important information to PWD designated assistance entities (e.g., family, friends, givers, HCPs, emergency medicine providers) under certain conditions. In some cases, a user's location can be tracked or determined to trigger and/or time alerts about upcoming maintenance tasks in a way that will increase the likelihood that the PWD will immediately perform the designated maintenance task. In some cases, methods, devices, and systems provided herein can use proximity to non-paired mobile computing devices to deliver data to PWD designated assistance entities.
