code for shearwear

I am making a program. A user can use that program (software) for up to 20
days, and from there on, the user must pay money and buy a licence code to
use it.

Usually I write the days left for free use on a separate file, but are there
any better ways to keep track of how many days the software has been used?

The question may be a little hard to understand, so please ask me if there
are any questions. And thanks in advcance!
