Terms and Conditions

1. Who We Are

PVMath is operated by Mohammed Ismail Pasha (Einzelunternehmen, trading as PVMath), Straubinger Strasse 1, 93055 Regensburg, Germany (contact@pvmath.com). By creating an account or using app.pvmath.com or pvmath.com (together, the “Platform”), you agree to these Terms and Conditions. If you do not agree, do not use the Platform.

2. What the Platform Does

PVMath provides an integrated software platform for ground-mount solar site screening and engineering support: project setup, solar resource and regulatory screening (SiteIQ), terrain analysis (TerrainIQ), layout generation (LayoutIQ), yield screening (YieldIQ), and economic screening (RevenueIQ), plus exportable reports and terrain/CAD files (PDF, DXF, LandXML). Outputs are generated from third-party data sources (PVGIS, Copernicus/SRTM DEM, OpenStreetMap) and automated calculations.

The Platform provides preliminary, early-stage screening outputs only. It is a decision-support tool for the early phases of project development and does not replace a bankable energy yield assessment, geotechnical survey, RTK/topographic survey, or detailed engineering design by a qualified professional. You are solely responsible for independently verifying all outputs before relying on them for investment, financing, permitting, or construction decisions.

3. Accounts and Plans

• You must provide an accurate email address to create an account and are responsible for keeping your login credentials secure.
• The Free plan includes 5 analyses per calendar month, as displayed on the pricing page. A project analysis is counted when LayoutIQ runs for a site. Running TerrainIQ, LayoutIQ, and YieldIQ on the same saved project in the same month does not consume additional analyses.
• Professional (50 analyses/month), Developer (250 analyses/month, team pool), and Enterprise (unlimited) plans are billed as described on pvmath.com. Limits reset on the 1st of each calendar month (UTC). Unused analyses do not roll over.
• PVMath may adjust plan limits, features, or pricing prospectively; changes will be reflected on the pricing page.
• We reserve the right to suspend or terminate accounts that abuse the free tier, attempt to circumvent usage limits, or violate these Terms.

4. Acceptable Use

You agree not to:

• Use automated means (scripts, bots, scraping) to bypass usage limits or extract data at scale without written permission;
• Resell, sublicense, or redistribute Platform access or outputs as a competing service;
• Reverse-engineer, decompile, or attempt to extract the underlying source code or models;
• Use the Platform to violate any applicable law or third party's rights;
• Misrepresent Platform outputs as a substitute for licensed engineering, surveying, or financial advice.

5. Your Data and Content

You retain ownership of the project data you input (site coordinates, boundaries, project names, parameters). As described in our Privacy Policy, saved projects and account data are stored in Supabase. We store a monthly usage counter to enforce plan limits. You grant us a limited license to process your input solely to generate and return the requested outputs.

6. Intellectual Property

The Platform, its software, design, branding, and documentation are the property of PVMath / Mohammed Ismail Pasha and protected by copyright and other intellectual property laws. These Terms do not grant you any rights to PVMath's trademarks, logos, or source code. Reports and export files (PDF, DXF, LandXML) generated for your own projects are yours to use for those projects.

7. Third-Party Data and Services

The Platform relies on third-party data providers (EU PVGIS/JRC, Copernicus/SRTM DEM via OpenTopoData, OpenStreetMap/Nominatim) and infrastructure providers (Supabase, Railway, GitHub Pages, Formspree, Brevo). PVMath does not control and is not responsible for the accuracy, availability, or continuity of these third-party services. Outages or data-quality issues at these providers may affect Platform availability or output accuracy.

8. Disclaimer of Warranties

The Platform and all outputs are provided “as is” and “as available,” without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy, or non-infringement. Solar resource, terrain, capacity, and yield outputs are preliminary engineering screening estimates based on automated calculations and third-party datasets; they are not certified, bankable, or guaranteed figures. RevenueIQ outputs (CAPEX bands, IRR, LCOE, payback) are indicative financial screening only and do not constitute investment, tax, or financial advice.

9. Limitation of Liability

To the maximum extent permitted by law, PVMath and Mohammed Ismail Pasha shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunity arising from your use of, or inability to use, the Platform — including decisions made based on screening outputs. Our total liability for any claim relating to the Platform is limited to the amount you paid us in the 12 months preceding the claim, or €100, whichever is greater. Nothing in these Terms excludes liability that cannot be limited under applicable German or EU law.

10. Changes to the Platform and Terms

We may update these Terms from time to time to reflect changes to the Platform, pricing, or legal requirements. We will post the updated version here with a new “Last updated” date. Continued use of the Platform after changes take effect constitutes acceptance of the revised Terms.

11. Termination

You may stop using the Platform and delete your account at any time by contacting contact@pvmath.com. We may suspend or terminate your access for breach of these Terms, non-payment, or misuse, with notice where reasonably possible.

12. Governing Law

These Terms are governed by the laws of Germany, without regard to conflict-of-law principles. Where you are a consumer resident in the EU, mandatory consumer-protection provisions of your country of residence remain unaffected. Any disputes shall be subject to the exclusive jurisdiction of the courts of Regensburg, Germany, to the extent permitted by law.
