Architecture that generates a notification when a user arrives at a location, but without exposing identity of the location. Moreover, the notification can be generated and transmitted at all times. The architecture comprises a reminder service that manages all reminder requests and approvals, a notification engine that notifies a requesting user when target user arrived at a specific location or one of a general category of location, and a user interface that allows the user to set reminders that are displayed when the target user arrives at the point of interest and approves other user reminder requests. The architecture can be run on a mobile phone, and manages user requests and user approvals for location based notifications, alerts a requesting user the target user arrived at one of previously-specified points of interest. Similarly, a general category of destination can be specified, rather than a specific point of interest.
