Terms of use
Last updated: November 2026
1. What Kavelradar is and is not
Kavelradar is an independent monitoring platform for municipal building plots. We are not an estate agent and not a party to any purchase or lease, you buy or rent from the relevant municipality, sometimes through an estate agent the municipality engages. Kavelradar is not affiliated with, and does not speak on behalf of, the municipalities whose listings we show.
2. Free and paid features
Visiting the website, creating an account, saving favourites and reading the step-by-step plan, the self-build guide and the glossary is free. As a Free user you can save up to 2 plots at a time and see 75% of the current listings; with Kavelradar Pro you can save without limit and see all plots. Kavelradar Pro (including the plot comparer, the overview of additional costs, tracking your progress, the price development per neighbourhood and the median price per m²) and the personal build guidance are paid services, on the terms stated on the relevant page. Kavelradar Pro is a subscription you take out via our payment provider Stripe that automatically renews every six-month period until you cancel (see "Cancellation and refunds" below).
3. Your account
Kavelradar is intended for people aged 18 and over. If you are younger, you need permission from a parent or guardian to create an account or take out Kavelradar Pro. You are responsible for the accuracy of your details and for keeping your password and the login links and codes we email you secret. To activate your account you confirm your email address via a link or code we send you. An account is personal and can be logged in on up to 2 devices at the same time; if you log in on a third device, you are automatically logged out on the device where you logged in longest ago. In case of misuse of the website we may block or delete an account. You can delete your account yourself at any time via My settings; if you have an active Kavelradar Pro subscription at that time, it is cancelled immediately without a refund for the remaining period. If your subscription has already renewed, first cancel via "Cancel subscription" in My account (see "Cancellation and refunds") and delete your account afterwards. If you are still within the 14-day cooling-off period and want to use that right, contact us via the contact page before deleting your account (see "Cancellation and refunds"). How we handle your data is described in our privacy policy.
4. Misuse
You may not circumvent Kavelradar's paid features or security (for example by viewing locked plots or Pro features without a subscription), attack, break into or overload the website or our systems, automatically collect (scrape), copy or resell data from the website, share your account with others, or use someone else's data or means of payment. In case of misuse or a reasonable suspicion of it, we may restrict your access to Kavelradar, temporarily block or delete your account and end a running Kavelradar Pro subscription. In case of serious misuse, this happens without a refund of the remaining period. If you do not have an account, we may deny you access to the website, for example by blocking your IP address. We may recover any damage caused by misuse from the person responsible for it.
5. Accuracy of data
We do our best to show plot data accurately and up to date, but cannot guarantee that all information is complete at all times. Prices are the prices as published by the municipality (the label "Official municipality price" means we take over that price, not that we set or guarantee it) and may change without notice. If a municipality only states a price excluding VAT, we convert it to a price including 21% VAT (buyer pays costs), marked "Calculated price". Such a calculated price is an indication, not a price set by the municipality. Shapes, dimensions, areas, locations and statuses may also differ or be out of date, for example because a municipality updates its website later or a source contains errors. In case of any difference, the information of the municipality always prevails. Always verify important details with the relevant municipality before making a decision.
6. Indicative calculations and general information
The price development per neighbourhood, the municipality's expected releases (a forecast by the municipality itself), the overview of additional costs, the step-by-step plan, the self-build guide, the progress checklist and the glossary are indicative calculations and general information, based on published data and common practice. The same applies to the plot drawings: the shape and dimensions, the marked front, the surroundings (such as water and greenery) and, where the municipality does not state it itself, the sun orientation are derived by us from the municipality's drawings and plot passports; the plot passport and the municipality's official documents prevail. They are not a valuation, not legal or financial advice and no guarantee of future value development or costs. Amounts, procedures and deadlines differ per municipality and change regularly.
7. Cancellation and refunds
Kavelradar Pro is a subscription via Stripe that automatically renews every six-month billing period unless you cancel. In your first six-month period you cancel via My account, under "Manage subscription"; this opens Stripe's customer portal. The subscription then continues until the end of that first period and is not renewed after that; there is no refund for the remaining days. Once your subscription has renewed, you can cancel at any time with one month's notice, via the "Cancel subscription" button in My account. You keep Pro for one more month; what you paid for the rest of the current period (including extra email addresses) is refunded pro rata, within a few business days to the payment method you paid with. If the current period ends within that month, the subscription stops at the end of the period and there is nothing to refund. You can also cancel via the customer portal; the subscription then stops at the end of the current period, without a refund. If you are a consumer and took out Kavelradar Pro for the first time less than 14 days ago, the legal right of withdrawal also applies. At checkout you explicitly request to start using Kavelradar Pro immediately; this means that if you withdraw within those 14 days, you only pay an amount proportional to the days you have already used, and get the remainder back. To use this right, contact us within 14 days via the contact page; the regular customer portal does not process an automatic refund for this.
8. Extra email addresses for alerts
With Kavelradar Pro you can add up to two extra email addresses under My settings that receive the same plot alerts, for € 4.99 per address per half year. The extra address becomes part of your Pro subscription: for the rest of your current period you pay a pro-rata amount right away, via your subscription's payment method, and after that it renews along with your subscription. Payment methods that do not support in-between payments, such as pay later, cannot be used for this. Each extra address first receives a confirmation email; only after confirmation does it receive the alerts. A confirmation link is valid for 7 days and you can request a new one. Only add addresses whose owner agrees to this. If you remove an extra address, it stops receiving alerts right away and you no longer pay for it from your next renewal; no refund is given for the current period. There is one exception: if you remove an extra address within 14 days of adding it, you automatically get the full amount charged for it back. This gives each extra address a 14-day cooling-off period. This only applies to extra email addresses; for Kavelradar Pro itself the rules under "Cancellation and refunds" apply. If your Pro subscription ends, your extra email addresses lapse as well.
9. Inviting others
With a Kavelradar account you have your own invitation link, found under My account. When someone creates an account through that link and takes Kavelradar Pro, the referral counts once that person has passed the 14-day cooling-off period with a paid subscription and no refund has been requested. For every 5 referrals that count you get 6 months of Kavelradar Pro for free, up to a maximum of 1 year per person (10 referrals). If you already have Pro, your next payment moves 6 months later. If you do not have Pro yet, you get 6 months of Pro without payment details; it then stops automatically unless you continue it yourself. The reward is granted as soon as you open My account after reaching the threshold. Only a new user who created an account through your link counts; your own account does not. In case of misuse, such as referrals that do not come from real new users, we may cancel referrals and rewards. A reward cannot be exchanged for money. We may change or end the programme; rewards already granted remain valid.
10. Liability
Kavelradar provides information as is, as an aid in your search. You use the website, the alerts and the calculations at your own risk. Kavelradar is not liable for decisions you make based on the information shown, nor for damage caused because: information is incorrect, incomplete or out of date; an alert does not arrive, arrives late or arrives twice; the website or a feature is temporarily unavailable or has a fault; you miss out on a plot or miss a registration, lottery or deadline; or a municipality, estate agent or other third party acts or fails to act. Kavelradar is never liable for indirect damage, such as consequential damage, loss of profit, missed opportunities or extra costs. These limitations do not apply in case of intent or deliberate recklessness on the part of Kavelradar. Always consult a professional for legal, financial and building advice.
11. Links to municipal websites and documents
Kavelradar places direct source links on plot pages to the official website of the relevant municipality and to plot-specific documents, such as plot passports, issue drawings, layout plans, design guidelines and model agreements. Kavelradar does not host or copy these documents: they are on the municipality's website and the rights to them lie with the municipality or other rights holders. The short description with each document is our own general explanation based on the title, not a summary of the content and no substitute for the document itself. On the plot page we state when we last checked the links. These municipal websites and documents are managed by third parties over which Kavelradar has no control, and may change or disappear without notice. We are not responsible or liable for their content, accuracy, availability or functioning. Always consult the source for the current version; use of them is at your own risk.
12. Plot drawings and maps
The plot drawings and maps on Kavelradar are our own, indicative representation. We make them ourselves, based on factual data such as coordinates, dimensions, area and status from public sources: the websites, plot maps and plot documents of municipalities, the cadastral map and other registers of the Land Registry (Kadaster, via PDOK) and map data from OpenStreetMap contributors. They are not copies of the municipality's documents. Each drawing states what its shape and dimensions are based on. The original plot documents are at the source, which we link to on every plot page; the rights to them lie with the municipality or the other rights holders. The Sources page lists which sources we use.
13. Personal build guidance
In addition to the platform, Kavelradar optionally offers personal 1-on-1 guidance when buying a plot and building a home, on the terms stated on the guidance page. The guidance consists of a pre-agreed number of advice sessions. Contact via WhatsApp or phone also follows the arrangements we make together in the introductory call; contact beyond that is not part of the guidance, unless we agree otherwise. Kavelradar is not a party to the agreement between you and your contractor, architect, notary or other third party in connection with this guidance, and accepts no liability for the actions, omissions, quality of work or financial arrangements of these third parties. This also applies when you use parties from Kavelradar's network. The final choice and responsibility for engaging a contractor, architect or other party always rests entirely with you.
14. Language
These terms are available in Dutch and English. In case of differences between the two versions, the Dutch text prevails.
