Absolutely - the same API that drives our user interface is available to you. We provide documentation so you can build a library in your favorite language to talk to IO
What about the data that my project generates? Where does it go? What happens to it? Are you going to sell it?
The data your store with IO is yours to manage and control. You can download it all anytime and we will never sell or give it away to another company. We feel strongly enough about this that we put it in our IoT Bill of Rights.
If you have any questions or issues with Adafruit IO, post up in the Adafruit IO Forums or chat with Adafruit staff and community members in real-time on the adafruit-io channel on the Adafruit Discord server.
