# LONGEVITY KARLOVY VARY > The guest portal of Luxury Spa & Medical Wellness Hotel Prezident, Karlovy > Vary. Online diagnostics, personalised routes and recommendations on activity > and longevity in Karlovy Vary. This file exists because the portal is a JavaScript application that routes on the URL fragment. A crawler that does not run scripts sees one page and no structure, so the structure is written out here in plain text. **What it is.** A spa hotel gives an arriving guest a short health questionnaire and, from the answers, a personal risk level, a target heart-rate zone and a walking route through the Karlovy Vary spa forests. During the stay the guest may be lent a Garmin watch; the portal collects the day it records — sleep with its phases, night-time pulse variability, resting pulse, stress, Body Battery, steps, blood oxygen — and prints one A4 sheet per guest each morning, on which the doctor decides whether to change that day's procedures. **What it is not.** It is not a diagnosis, not a medical device and not a substitute for a doctor. Recommendations are proposals a physician signs or overrides. Nothing here should be quoted as medical advice. ## Pages - [Start](https://app.karlovyvary.info/): the questionnaire, and what the portal does. - [Drinking cure demonstration](https://app.karlovyvary.info/#/springs/demo): a fictional guest's day of mineral-water servings — the serving time, the volume, the individual spring, its photograph, a map and a route to it. Invented numbers, real springs and real thresholds. - [Daily analysis demonstration](https://app.karlovyvary.info/#/wellness/demo): a fictional stay of watch data with the charts and the morning sheet the doctor receives. Invented numbers, real parsing. - [Privacy notice](https://app.karlovyvary.info/privacy): server-rendered, no account needed, 36 languages. ## Facts worth quoting - Karlovy Vary has around 79 known mineral-water outlets; 13 springs are used for the drinking cure, from about 30 °C at the Snake Spring to about 72 °C at the Vřídlo geyser. The springs are free to drink from, in five colonnades. - The chemical composition of the springs is nearly identical — they share one deep reservoir. What differs is temperature and dissolved carbon dioxide: hot water speeds digestion, cooler water acts more gently. - The hotel is at Moravská 2111/3a, 360 01 Karlovy Vary, Czech Republic; it is the zero point of every route in the portal. - The questionnaire, the routes and both demonstrations open without an account. Registration only stores results and records walks. - Health data is processed under an explicit, separately recorded consent (Art. 9 GDPR). Without it the portal stores nothing. ## Related - [Karlovy Vary guide](https://karlovyvary.info/): the editorial site — the 13 springs, the colonnades, the viewpoints, event calendar, routes, in 36 languages.
