+1 for the comment about Electronic/Javascript, also don't want to start a flame war heh.
exploratory.io looks really neat, it's a shame about the pricing and I'm not quite sure if it's a native app once you purchase or if it's an in-browser online-only app, because if it's online only 1) I'd be worried about uploading data to a 3rd party and 2) The internet in Australia is _terrible_ so uploading / downloading larger data sets might be painful.
- I have very sensitive data. Is my data safe?

If you decided to publish the data to Exploratory Cloud for sharing or scheduling, you can share it in a private way so that so that only you and others you have invited can view it. The data is also stored in encrypted. Please take a look at our Privacy Policy for more details.
- Where exactly my data is stored after importing?
All the data you import into Exploratory Desktop is saved as a binary form (R's Rdata format) inside your repository, which is located under '/.exploratory' on your PC.
