Hi. Thank you for the question. + this comment?
1. Never sell it. See text in the post. I know this is normal in the US, but way less so where I/we are from in Scandinavia. There's a fair mistrust given the norms in other countries, but as said in the post, I would rather abandon the project then start selling the data.
2. The data of the personality profiles gets processed anonymously. You as a user cannot even access the anonymous-results directly, there's an encrypted service in between the data-points, fetching only select data.
3. Everything is encrypted, on device, from device to servers, and on servers.
