Terms of Service

1. Acceptance of Terms

By accessing or using Waveshed ("Service"), you agree to be bound by these Terms of Service. If you do not agree, you may not use the Service.

2. Description of Service

Waveshed provides browser-based RF propagation simulation powered by the Aether Engine. The Service runs computations locally in your browser using WebAssembly and WebGPU. No server-side processing of simulation data occurs in the free tier.

3. Simulation Results — No Warranty

Simulation results are outputs of a propagation model: approximations based on terrain models and propagation algorithms, not measurements and not guarantees of real-world coverage or link performance. They must not be relied on for safety-of-life, regulatory, planning or financial decisions without independent verification (for example field measurements).

Terrain data is sourced from public datasets (Copernicus, SRTM) with inherent resolution and accuracy limitations. The Service makes no guarantee of accuracy for any specific location or scenario.

4. Intellectual Property & Restrictions

The Service, including its software, WebAssembly binaries, GPU shader code, algorithms, design, and documentation, is the intellectual property of Waveshed. You are granted a limited, non-exclusive, non-transferable licence to use the Service for its intended purpose.

You may not:

• Reverse-engineer, decompile, disassemble, or extract source code from WebAssembly binaries or GPU shaders delivered by the Service
• Redistribute, sublicence, or commercially reuse any part of the Service's software or algorithms
• Circumvent usage limits, rate limiting, or access controls
• Use automated tools to scrape, extract, or bulk-download data from the Service
• Resell access to the Service without written authorization

The downloadable Aether engine binaries (used by the Waveshed QGIS plugin) are governed by their own Aether Engine EULA, which permits non-commercial use only; commercial, governmental and organisational use requires our prior written permission.

Your simulation results and exported data (PNG, GeoTIFF, KMZ) remain your property.

5. Acceptable Use

You agree not to use the Service:

• For any purpose that violates applicable law
• To interfere with or disrupt the Service or its infrastructure
• To transmit malware, exploit vulnerabilities, or conduct security attacks
• In a manner that negatively impacts other users' experience

6. Third-Party Data & Attribution

The Service uses third-party terrain and map data under their respective licences:

• Copernicus DEM (ESA) — open licence
• SRTM (NASA) — public domain
• OpenStreetMap contributors — ODbL
• OpenFreeMap & OpenMapTiles (basemap and building tiles) — ODbL
• Mapterhorn terrain tiles (Copernicus GLO-30 and national open elevation models; full list on its attribution page) — open licences, attribution required
• swisstopo (basemap, terrain and building tiles, Switzerland) — open use licence, © swisstopo
• IGN BD TOPO® (building footprints and heights, France) — Licence Ouverte / Open Licence 2.0, © IGN

You are responsible for complying with these licences when using exported results commercially.

7. Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

8. Limitation of Liability

To the maximum extent permitted by applicable law, Waveshed accepts no liability for anything arising out of or relating to your use of the Service or reliance on simulation results, including any direct, indirect, incidental, special, consequential, or punitive damages. This does not exclude liability that cannot be excluded under mandatory law, such as liability for gross negligence or willful misconduct.

9. Governing Law & Jurisdiction

These terms are governed by and construed in accordance with the laws of Switzerland, without regard to conflict of law provisions. Any disputes shall be subject to the exclusive jurisdiction of the courts of Zurich, Switzerland.

10. Changes to Terms

We reserve the right to modify these terms. Material changes will be posted on this page with an updated date. Continued use after changes constitutes acceptance.
