Abstract: A device receives a time-based restriction for usage by a first user with respect to an application, a website or a device-level function. The device receives encrypted data indicating a usage by the first user on a second device with respect to the application, website or device-level function. The device determines that at least one of the usage by the first user on the second device or a usage by the first user on the device with respect to the application, website or device-level function violates the time-based restriction. The device provides, in response to the determining, a notification that the time-based restriction has been violated by the first user.

Abstract: A first calendar of a first user can be stored in a database system. The first calendar may include a plurality of event records. A delete command may be received to delete at least a first portion of the first calendar. The at least a first portion of the first calendar may be marked as deleted by one or more flags. After marking, the at least a first portion of the first calendar may be updated in response to a change made to a second event record of a second calendar of a second user. A recover command may be received to recover the at least a portion of the first calendar. The one or more flags may be changed to indicate that the at least a portion of the first calendar is not deleted. The first event record may be provided to the first user with the changed information.

Abstract: A meeting originator associates a file with a meeting event by dropping the file on a meeting event window displayed within a calendar window. The file is copied to a directory on the originator's computer and a meeting invitation is created containing a directory path to a corresponding directory on a server that stores a copy of the file. The meeting invitation is sent to the server for distribution to attendees of the meeting, who access the file from the server. The originator also indicates permissions on the server directory for the attendees. The file may be modified by the originator, or by an attendee having appropriate permissions, by dropping a modified version on the meeting event window. The server notifies the attendees and/or the originator that the meeting event has changed.
