The data that is collected and sent by the Graticule android app to the website is as follows:
 Due to lack of user accounts, a randomly generated un-guessable identifier stored in the android app, which can be reset by the user as needed.
 Publicly displayed if you have the tracking link.
 Only used internally for limiting abuse / debugging issues.
All beacons, except the last one, are removed every 24 hours.
All beacons older than 1 year are completely removed on the first day of each month.
