SITEDIA · GERMANY
Terms of use
Effective: 15 October 2026
1. Scope
These terms govern the use of sitedia (the “service”) in its Germany edition. By using the service you accept these terms. You can save or print this page.
2. The service
From open geographic data, the service produces site analysis diagrams, 3D models, sections and sun, wind and thermal comfort simulations.
Basic features work without an account. Pro features need a paid pass; the Pricing page lists them.
The Germany edition covers the city areas of Berlin, Bochum, Bonn, Cologne, Darmstadt, Dortmund, Dresden, Duisburg, Düsseldorf, Essen, Frankfurt am Main, Freiburg, Hamburg, Heidelberg, Karlsruhe, Leipzig, Mannheim, Stuttgart and Ulm. How complete buildings, heights, building ages, parcels, planning data and green space are depends on the date, accuracy and availability of the source data. Not all data exists everywhere: building ages and some storey counts are estimated, and new buildings may be missing. The Data sources page gives the full list.
3. Account
You can create an account with Google or with an email address. You are responsible for your account and sign-in details. An account may not be transferred or shared. The service is not intended for people under 16, who cannot create an account.
4. Paid pass
Pro features are used with a paid pass. The types of pass, prices and lengths are shown on the Pricing page and at checkout. A pass only works in the edition where you buy it: a pass from the Germany edition covers sites in Berlin, Cologne, Stuttgart and Karlsruhe.
The pass starts when the payment is confirmed and ends on the same day and time 3 months or 1 year later, depending on the pass. If the last month has no such day, it ends on the last day of that month. If you buy a pass while another is running, the new one starts when the current one ends.
The pass is a one-off payment and does not renew automatically. When it ends, free features stay available. You must be at least 18 to buy a pass.
The pass is sold on behalf of sitedia by Polar Software, Inc., which acts as Merchant of Record and processes the payment. You buy the pass from Polar; your right to use the Pro features is granted by sitedia under these terms. Payment is also subject to Polar’s checkout buyer terms. None of this limits the rights the law gives you as a consumer that cannot be excluded.
Withdrawal (14 days) and refunds are described on the Withdrawal and refunds page.
5. Results
You may use the results in student work, reports and commercial projects, respecting the licences of the source data and the required credits.
The pass gives you no rights in third-party data and does not allow bulk extraction or resale of source data. Data from OpenStreetMap (paths, rail lines) is available under the ODbL 1.0, and these terms do not limit your rights under that licence. Open government data is reused under the Data licence Germany (Zero or Attribution, version 2.0) or CC BY 4.0; that reuse does not mean the State of Berlin, Geobasis NRW, LGL Baden-Württemberg, BKG or any other data holder endorses sitedia or your results.
Diagrams based on ALKIS parcels, land-use plans and development plans are sitedia’s own processing. They are not extracts from the land register (Liegenschaftskataster) or plans in force, and must not be presented as such.
The service does not keep results in your account. Download the files you need to your device.
When you show or share a result, keep the credit line shown under the diagrams.
6. Prohibited use
The following is not allowed. If it happens, we may restrict the account after telling you the reason and how to object.
- Bypassing authentication or usage limits
- Using another person’s account without permission
- Large-scale automated requests that disrupt the service
- Infringing the rights of others
7. Liability
The results support early design. They are not a boundary determination, legal property lines, or a structural or environmental assessment. They do not replace checking the plans and rules in force or professional advice.
Sun, shadow, wind and thermal comfort: Simulation for orientation only, not legally binding. The sunlight simulation is not a demonstration of compliance with DIN EN 17037 or DIN 5034-1.
Planning: For orientation only — Berlin: land-use plan (Flächennutzungsplan), development plans (Bebauungspläne) and protected areas from Geoportal Berlin; Cologne: the City of Cologne’s land-use plan and overview of development plans; Stuttgart and Karlsruhe: actual land use from ALKIS instead of statutory plans; Hamburg: land-use plan (Flächennutzungsplan) and development plan outlines; Frankfurt am Main: regional land-use plan and development plans; Darmstadt: actual land use from ALKIS; Düsseldorf, Dortmund, Essen, Duisburg, Bochum, Bonn, Mannheim, Freiburg, Heidelberg, Ulm, Leipzig, Dresden: actual land use from ALKIS, partly with development plan outlines. The municipality’s own plans are what count. An empty area does not mean no rules apply. Check with the municipality before relying on it.
Design and safety decisions must rely on documents from the competent authorities and on professional advice.
Nothing in these terms excludes or limits any liability that the law does not allow to be excluded or limited, and nothing affects your legal rights as a consumer.
8. Changes
If we change these terms, we will announce it in the service at least 7 days before the change takes effect (30 days if the change is to your disadvantage).
9. Governing law and complaints
Send questions and complaints to [email protected].
These terms are governed by the law of the Republic of Korea. If you are a consumer living in Germany, you also keep the protection of the mandatory provisions of German consumer law and you can go to the courts where you live.
Effective date
These terms apply from 15 October 2026.
