Why Profilia exists.

Who I am

I'm Adrien Albuquerque. Trained as a software developer, fascinated by psychology since my teens, I built Profilia because the personality tests available online were either locked behind paywalls (16personalities, Truity), or used as a pretext to harvest emails and resell ad attention. None of them respected both the rigor of the underlying psychological models AND the user's time.

Profilia is my antidote: ten tests grounded in established models, free, no account, no marketing tracking. I've been maintaining it solo since March 2026.

Why exactly these ten tests

Each test covers a distinct dimension of personality — behavior, identity, rhythm, motivation, learning, attachment — and is grounded in a published, widely used scientific model. None are invented for decoration.

The end goal is the Personality DNA: by completing at least three tests, you get a meta-profile that cross-references the axes to reveal what no single test can. That's what sets Profilia apart from a quiz aggregator.

Methodology and sources

Every test is implemented from publicly available scientific literature. Here's the academic source for each:

• DISC — DISC model, William Marston, 1928. Four behavioral dimensions (Dominance, Influence, Steadiness, Compliance).
• RIASEC — RIASEC model, John Holland, 1959. Six vocational types for career orientation.
• Jung Archetypes — from Carl Jung's psychological archetypes (1921), formalized by Margaret Mark and Carol Pearson (2001).
• Chronotype — Dr. Michael Breus's four-chronotype model (Lion, Bear, Wolf, Dolphin), The Power of When (2016).
• VARK — Neil Fleming's VARK model (1987). Four learning styles (Visual, Auditory, Read/Write, Kinesthetic).
• Love Languages — Gary Chapman's five love languages (1992).
• Four Temperaments — Hippocrates's classical temperaments (5th century BCE), re-articulated by Galen and Kant.
• Four Tendencies — Gretchen Rubin's model, The Four Tendencies (2017). Response to inner and outer expectations.
• Leadership Style — synthesis of Kurt Lewin (1939), Hersey-Blanchard (1969), and Daniel Goleman (2000).
• Spirit Animal — synthesis of animal symbolism across several traditions (Native American, Celtic, Asian). The one cultural outlier among ten clinical tests.

Privacy commitment

Profilia is deliberately the opposite of the dominant business model for quiz sites. Concretely:

• No account required to take a test, see your results, or share them. If you create an account, it's only to keep history across devices — toggleable.
• No marketing cookies, no ad pixels, no data resale. Internal tracking anonymizes via a daily-rotating salt (Plausible-style, GDPR-compliant under France's CNIL audience-measurement exemption of July 4th, 2025).
• Source code not yet public but could become so. If transparency matters to you, ask.
