Reference project
Vitalis — six self-checks, zero data leaving the device

About this project
The most sensitive project here, and therefore the one with the strictest rules. The six self-checks do not use invented questionnaires but ones recognised in the field — and the scoring behind them is tested separately, because an arithmetic error here would unsettle people. One point mattered to us in particular: anyone who agrees on the question about suicidal thoughts immediately gets a crisis notice — regardless of how the overall result turns out. On top of that a heart and BMI check, clearly written articles with sources, and a help page with emergency numbers. Everything runs exclusively in the browser: there is no server that ever gets to see the answers.
What this project is — and what it is not
A reference project from our own workshop — not an off-the-shelf template. Below is an honest account of what works and what is still missing. If you want to take it over as it stands, that is possible on request.

Pakete & Festpreise ansehen What already works
- Six self-checks: mood, anxiety, stress, sleep, exhaustion and memory
- Every answer stays in the browser — nothing is transmitted or stored
- Immediate crisis notice on distressing answers, independent of the overall result
- Heart and BMI check with a plain-language interpretation
- Articles with sources instead of half-knowledge
- Help page with emergency and counselling numbers
- Light and dark mode, operable by keyboard and screen reader
What is still missing
- Anyone with "reduce motion" switched on at the operating system level currently lands on an error page — of all things the setting people with migraine or vertigo need. Next on the list
- The legal classification as a health offering is not finally settled — the checks explicitly do not replace a medical diagnosis
- No automated checks on changes
- Results cannot be taken away as a PDF yet
