Except as expressly permitted in this Agreement, you may not share, sell, rent, lease, or transfer the software, your license, your user name, or your product key. You may not reverse engineer, decompile, disassemble, or create derivative works from the software. MedCalc Software reserves all rights not expressly granted under this Agreement.

Single-user perpetual license

If you purchase a single-user perpetual MedCalc license, you receive a non-transferable, perpetual right to install the software on your desktop and laptop computers, provided neither computer serves as a network server, and to use the software on a non-concurrent basis on those computers.

If you purchase a network license for the required number of concurrent users, the software may be used on one network server during the subscription period, subject to the applicable concurrent-user limit.

Disclaimer of warranties - Limitation of liability

The software is designed and provided as general-purpose software and not for any particular user purpose. You acknowledge that no software is error-free and that you should back up your files regularly.
