Panic's apps do this if I recall correctly, the day counter of your trial only decrements for days you've actually run it.

As a user, this is my preferred way of having things work out. For SaaS, though, I can understand why a company would eventually want to purge incomplete, unconverted trials from their servers.

Perhaps a system that offered 14 free days of use could expire the account after 60 or days. That seems like a reasonable compromise to me.
