Regarding Amazon, “Alexa” means their Alexa Voice Service which includes third party services (like our skills) and other related Software.
When you use our skills you have to talk to Alexa. This voice input is sent to Amazon where it is used to understand what our skill should do for you. This is absolutely necessary to be able to provide our Connect SmartHome services to you.
We never collect or share personal data with our skills.
To improve our services we analyse automatically how often utterances are spoken and other analytics. This is done automatically by Amazon in the Amazon Developer Portal.
