The Silver account includes all the features of the free account. In addition, the user will be able to download a Windows application that will allow creating, editing, and viewing multiple calendars and contacts on their PC. Viewing modes include day, week, and month with day side-by-side, and multiple calendars merges with colors indicating calendar membership. These calendars and contacts are available even when there is no Internet access (e.g. on a laptop on an airplane). When Internet access is available, the calendars and contacts are synchronized with the ClearSync server and under user control, shared with others in their sharing group. The Silver account also includes downloadable Palm applications that allow creating, editing, and viewing multiple calendars and contacts on their PalmOS handheld. The Palm calendar application includes support for viewing calendars individually, side-by-side, or merged with color indications of which calendar an event is on. The one-button Palm sync will sync the Palm to a PC and also the PC to the ClearSync server. Silver account holders without handhelds can sync to the ClearSync server with a single mouse click. Calendars can be printed from the PC in a variety of formats. The Silver account includes technical support by email. A 30-day free trial is available. A silver account costs $19.95 per year and $9.95 per year for additional users purchased at the same time. Thus a two-person sharing group can have ClearSync Silver for $29.90 per year.

The Silver account is most appropriate for people who want their calendar and contact data backed up beyond their PC and Palm handheld, or who want to create or edit calendars or contact lists that are shared with others. This level of service is often selected by those who want to share using their PC but either do not use a handheld device or have a Palm handheld device that does not have wireless capability. Cost-sensitive groups will typically have one or two Silver account holders and the rest free accounts. The Silver account is for those who do not have a need to share data from their Palm device while away from their PC.
