Refund Policy
The demo version allows you to try all of the EXIFutils features, and is only limited in 1) the number fields you can reference in a single command, 2) the length of the fields you can enter, and 3) the number of files you can process in a single command. There is no time limit on how long you can use the demo version, so you have plenty of time to determine whether EXIFutils meets your needs.

As such, no refunds will be issued for EXIFutils software on the basis that it does not meet your needs, unless you can show that the lack of required functionality could not reasonably be identified in the demo version.
