Single user

• A single-user license for Stata is a license that allows a maximum of one simultaneous user of Stata.
  
  
• A single-user license allows Stata to be installed on a computer at work and a computer at home, since it would be impossible for one person to be using both computers at the same time.
  
  
• A single-user license allows Stata to be installed on a computer at work that is in a public area and is used by multiple people, but it may not be remotely accessed. If Stata has been installed in a "public" computer that many people use, you may not also install it on a home computer.
  
  
• A single-user license may not be installed on a network. The smallest network license is a 2-user.
  
  
• A single-user license comes with either one Complete Documentation Set or one Base Documentation Set.

Network

• An N-user network license is a license that allows a maximum of N simultaneous users. It is a perpetual license without an expiration date.
  
  
• The minimum size network license that may be purchased is a 2-user.
  
  
• The size of the license can be increased at any time at a reduced charge. If you currently own a 5-user network license, the cost of adding another user would be the cost of adding user number 6.
  
  
• All network licenses come with either one Complete Documentation Set or one Base Documentation Set regardless of the size of the network. Additional documentation may, of course, be purchased.
  
  
• Upgrade discounts are offered as new releases of Stata become available.

Volume purchase

• Volume purchases are just purchases of single-user licenses of Stata placed at the same time in order to take advantage of falling per unit costs.
  
  
• Volume purchases come with either one Complete Documentation Set or one Base Documentation Set regardless of the quantity of licenses purchased. Additional documentation may, of course, be purchased.
  
  
• Purchasing N copies of Stata under volume-purchase pricing does not mean that the copies are "tied" together. For example, you may elect to upgrade only 1 of the N copies and wait to upgrade the other (N - 1) at a later time. With an N-user network license, there is only one license, so it cannot be broken up.

Leases

• A Stata lease is an N simultaneous-user license that expires after one year. If a new release of Stata occurs during this year, the new release is sent to the lease holder at no additional charge.
  
  
• The sizes of Stata/SE leases are 15, 25, 50, 100, 150, 200, 250, 300, etc. The minimum-size Stata/SE lease is 15.
  
  
• The sizes of Stata/MP leases are 10, 15, 25, 50, 100, 150, 200, 250, 300, etc. The minimum-size Stata/MP lease is 10.
  
  
• All Stata leases include one Complete Documentation Set and a one-year subscription to the Stata Journal.

Educational Lab

• An Educational Lab license is appropriate for student use or for use by faculty for teaching. It is not appropriate for faculty research, government or corporate training.
  
  
• The minimum-size Educational Lab license is 10. A 10-user Educational Lab license is a license for 10 simultaneous users. Stata may be installed on a network, or you may install Stata on 10 individual computers.
  
  
• It is possible to purchase a combination Lab—say a 6-user Stata for Windows license and a 4-user Stata for Macintosh license.
  
  
• The Educational Lab charge is a one-time charge and not an annual fee.
  
  
• A Base Documentation Set is included with the purchase of an Educational Lab regardless of the size of the license. Additional documentation may, of course, be purchased. A LabDoc is a very economical way of acquiring extra documentation for a lab.
  
  
• Upgrade discounts are offered as new releases of Stata become available.
  
  
• A GradPlan is a great complement to any lab!
