Profilia: 10 free tests, one merged profile, comparable with a friend

Hi Product Hunt, I am Adrien, I built and run Profilia alone. It started as a personal irritation. Every personality test I tried hid the result behind a sign-up, an email or a paywall, and the free part was a teaser. So I built the version I wanted: ten tests, the complete result on screen the second you finish, no account, no ads, nothing gated. An account exists but it is optional and only keeps your results across devices. The part I did not expect is what people do with it. Taking several tests merges them into one aggregated profile, and you can put that profile side by side with someone else. So I added a group mode: one person opens a link, everyone takes the same test on their own phone, and the group gets a shared grid. One evening, eight people took the DISC test on their phones within the same five minutes, from a link someone had shared with them. That one session ended up with 21 participants and 13 completed profiles. I never met them and I have no idea who they are. That is the moment this stopped being a side project for me. It runs in French, English, Spanish and Portuguese (Brazil and Portugal). I am the only person working on it, so I am mostly here for the hard questions: the scoring, the science behind each test, and where the group mode falls apart. Ask me anything.
