Terms of Use
1. What it is (and what it is not)
DruckZugPro is a web-based tool for a rough preliminary check of chimney and appliance combinations based on DIN EN 13384-1. It is intended solely for initial technical orientation. Under no circumstances does this software replace the official, certified cross-section calculation or the final structural and safety inspection by the responsible district chimney sweep.
2. Beta Phase and Software Bugs
This project is in an early development phase (Beta). We strive for clean code and exact physical models, but bugs or deviations can never be completely ruled out at this stage. This means: The calculated results may contain errors. Use of the tool is therefore strictly at your own risk.
3. Disclaimer of Liability
We provide this tool "as is". We assume no liability for the accuracy, completeness, or timeliness of the generated data and exports. If you purchase materials, start construction work, or bindingly order appliances based on these preliminary checks, you do so at your own risk. We are not liable for direct or indirect damages arising from the use of the software. You must have all calculated values validated by a qualified professional.
4. Local Data Processing (Privacy by Design)
A core technological advantage of DruckZugPro: The entire calculation logic runs locally in your browser. At no time do we transfer your entered project, building, or appliance data to our servers, nor do we analyze it. What is calculated on your machine stays on your machine.
5. Availability and Changes
We reserve the right to adapt the tool at any time, roll out new features, or completely discontinue the service if necessary. There is no entitlement to constant availability of the software.
