The Location Sensor is a Power Add On feature.
The location sensor feature is turned on/off with a simple check box. When it is turned on the Store Locator Plus plugin will query the user’s browser and request their current location. If the browser allows location queries it will return their geographic location which will be used to set the default search location. Please note that Chrome has restrictions since Chrome version 50 (released in 2016) they will only return locations using location sensor if they are generated from a secure site. See the Google developers console discussion for more information.
Other browsers, such as Firefox allows users to disable their location by using privacy from their browser on a per-page or internet-wide basis. Additionally, some browsers may not support this feature and some browsers return inaccurate location data.
Location Aware Browsing
Accuracy varies greatly from location to location. In some places, our service providers may be able to provide a location to within a few meters. However, in other areas it might be much more than that. All locations returned by our service providers are estimates only and we do not guarantee the accuracy of the locations provided. Your settings within the Plug-in may also effect how many locations are shown nearest to the site visitor, such as radius, number of results to return and canter of map settings.
