The email you receive from Braintoss includes an indication of where you were when you sent the Braintoss.
The location marker is made up of two parts. The marker image which has a URL to the GPS coordinates (more accurate) and a text link to the nearest address (less accurate).
This is based on GPS information from you phone and a lookup of the coordinates, and it is there to help you quickly remember what you said or meant.
Unfortunately this technology is not 100% accurate and we may receive coordinates of an address close to you or even from a location you were just before. So please consider it an approximate marker.
If you would like to turn it off send a text Braintoss with the words set location off in the message. For more email settings please see How do I change the format of the email?
