Hi Jacob, thank you for leaving a review, your feedback is important to us. The Garden Planner relies on being connected to our servers to work, so it's not possible to use it without an Internet connection I'm afraid.
With the online product we can keep backups of customers' data, and we store copies of all save points so if you do lose Internet connection we can usually restore your plan to the most recent save point. The Garden Planner also includes a number of features which require online access such as planting reminders by email.
However we're always looking for ways to make the Garden Planner even more useful for our customers so I will forward your email on to our development team for their consideration.
For now, you can save your plan as a PDF that you can refer to while offline, we'll contact you with details of how to do this.
