Single User License: Installation of the program purchased under a single user license is restricted to one single personal computer owned by or under control of the licensee plus one additional computer also owned by the licensee. However, at any given time only one copy of ATLAS.ti may be in use.

In typical training sessions, more than one copy of the program is used concurrently. This is NOT covered under the single user license; you must purchase a multi user license for such applications.

The Multi-User License (Concurrent Use License) permits installation (full server, plus lightweight client installation) and concurrent use of the program on multiple PCs of the license holder and/or multiple work stations of a Local Area Network, up to the amount covered by the license.

Student Licenses can only be purchased by fulltime students of accredited educational institutions with PROOF OF ELIGIBILITY.

Student licenses are PERSONAL licenses and can NOT be purchased by or through institutions or organizations. A program purchased under a student license must NOT be installed on an institutional computer. (Organizations can provide ATLAS.ti to their students via a) computer pool installations of ATLAS.ti multi-user licenses or b) by contracting a Campus License).

Under no circumstances must software obtained under an ATLAS.ti Student License be used in a commercial context of any kind. This includes training, non-academic research, and other activities not related to the licensee's personal education. Student licenses cannot be upgraded.

Except for these usage restrictions, the program is 100% identical to the full version. It is NOT time-limited, i.e. can be used indefinitely.
