Can I use TherapyCharts without internet access?

From TherapyCharts

No. TherapyCharts is a web-based psychology practice management and electronic health records (EHR) system. Because it is web-based, internet access is required. When you use TherapyCharts, none of your patient records will be stored on your local computer hard drive. This frees you of the cost, hassle, and liability risk of storing your own records and managing your own back-ups.
