Frequently Asked Questions
What is Kvadex?
An analytics platform that maps the entire apartment market in Belgrade and Novi Sad, removes duplicates, and displays aggregated price data — by municipality, neighborhood, and construction type.
Where does the data come from?
Our system collects data from the entire real estate market in Belgrade and Novi Sad daily, merges identical listings from different sources into a single record, and calculates statistics.
Does Kvadex collect personal data?
You do not need to register or create an account to use the platform. Visits are anonymous, and we do not collect visitors' names, email addresses, phone numbers, or addresses.
Do you use analytics and cookies?
We use Google Analytics 4, PostHog, and Microsoft Clarity for anonymous, aggregated statistics about visits and page interactions. Microsoft Clarity additionally records anonymized session replays and heatmaps, with any text you type masked. Cookies support this purpose, and the data is not connected to individual user identities.
How often is it updated?
Once daily. The system crawls all sources, retrieves new listings, updates prices, and removes inactive ones.
Do you advertise or sell apartments?
No. Kvadex is purely an analytics tool. We don't sell apartments, don't list them, don't advertise agencies, and don't broker transactions. We only display data.
What is "Under the Radar"?
Apartments whose price per square meter is more than 20% below the average for their neighborhood or municipality. The algorithm automatically identifies these listings — they could be pricing errors, urgent sales, or simply good deals flying under the radar. Not a purchase recommendation.
Is the data accurate?
Data is for informational purposes. We pull it directly from original sources — if a listing was entered incorrectly at the source, that error may be reflected here too. We try to filter obvious anomalies, but cannot guarantee 100% accuracy.
Which municipalities do you cover?
All 17 Belgrade municipalities and Novi Sad with surrounding areas. Belgrade: Stari grad, Vračar, Savski venac, Novi Beograd, Zemun, Čukarica, Rakovica, Voždovac, Zvezdara, Palilula, Mladenovac, Lazarevac, Obrenovac, Surčin, Barajevo, Grocka, and Sopot.
