The data card Email Insights shows you how to deduce your mood from the texts in you emails.
The basis for this graph is the content of your sent messages (of up to 1 month) from all connected email accounts. These are analyzed on our servers using the open source software Polyglot, i.e. your data is never shared with third parties and only you can see the result. We want to show you how (free) email providers can use your email and other texts to display targeted advertising, e.g. whenever you are usually in best mood.
Directly below your mood curve, we also show you the number of emails you receive and send and how many of them fall outside working hours (8:00-18:00). Maybe you can see a connection between the number of emails you receive or send and your mood on different days of the week.
