I’m trying to figure this out now. I just downloaded the beta version with Helio. Reading Helio’s privacy policy they state they “sell or share your personal information with third parties” for business and commercial purposes.
If you print proprietary designs, prototypes, or personal items: You should be aware that the details of these models will be sent to Helio Additive and their partners. Given that your data may be sold, you should carefully consider if the benefit of the feature outweighs the potential privacy risk.
If their gcode damages your printer in any way they are not liable. Any dispute resolution has to happen in Hong Kong.
I really wanted to check this out but I don’t think it’s worth letting them sell all of my data including the g-code and they hold no responsibility if they damage your printer.
