Questions about the quizzes
Yes, completely and permanently. Decisio.be is an independent project, with no advertising and no sponsor. All quizzes, articles and recommendations are and will remain free.
Your individual answers, no: they stay in your browser and disappear when you close the page. When you reach the result, we record an anonymous count only — which quiz, which region, the total score, the result you got and the date. No IP, no cookie, no identifier: those rows cannot be traced back to you, and we use them purely to see which topics are useful.
The quizzes are based on Belgian tax and administrative rules in force in 2026. They provide general guidance, not personalized legal or financial advice. For important decisions, always consult a professional (notary, accountant, financial advisor).
In Belgium, rules vary significantly by region. Registration duties of 12.5% in Brussels vs 3% in Wallonia or 2% in Flanders, different energy grants, separate employment agencies (Actiris, Forem, VDAB)... Knowing your region allows us to adapt the questions and especially the final result with the right info.
Of course! You can choose any region at the start of the quiz. This is useful if you're considering moving, buying in another region, or simply want to compare situations. Click "Restart" at the end to retake the quiz with a different region.
The Energy & renovation, Car & mobility, Health & insurance and Family & parenthood quizzes are in preparation. They will be released gradually throughout 2026.
