Is my data uploaded anywhere? No — all calculations, saved projects, and preferences stay on your device. The one exception is Vectorbox's optional weather lookup, which sends only the airport code you search to a public U.S. government weather service (not to us). See our Privacy Policy for details.
I bought Pro but it's not unlocked. Open the app's Settings screen and tap "Restore purchases".
