End-User Licence Agreement and Terms of Sale

Last updated: 9 November 2026

These terms are a legal agreement between you (the "User") and Shanthosh K V, Bengaluru, Karnataka, India ("the Developer"). They cover the FoamStudio desktop software, its installer, updates, documentation and licence service (together, "the Software"). By downloading, installing, activating or using the Software, you accept these terms. If you do not accept them, do not install or use the Software.

Summary (not a substitute for the terms): proprietary software, licensed not sold · ₹3,000 per year · up to 3 computers · no reverse engineering, cracking or key sharing · refund within 7 days · results must be verified independently.

1. Ownership

1.1 The Software is proprietary. It was designed and written independently by the Developer. All rights, title and interest in it belong solely to the Developer. This includes copyright in the source code, object code, user interface, graphics, documentation, case templates and validation material. These rights are protected by the Copyright Act, 1957 (India), the Information Technology Act, 2000, and international copyright treaties.

1.2 The Software is licensed, not sold. Paying the fee gives you a limited right to use it. It does not transfer ownership of the Software or of any copy.

1.3 "FoamStudio", its logo and its look are the Developer's identifiers. You may not use them without written permission.

2. Licence granted

2.1 Once you pay the applicable fee, the Developer grants you a non-exclusive, non-transferable, non-sublicensable, revocable licence. It lets you install and use the Software:

  1. for the term you paid for (12 months from purchase unless stated otherwise);
  2. on no more than three (3) computers at a time, each activated with your licence key;
  3. for your own internal, academic or commercial engineering work.

2.2 Trial. A free trial of 30 days may be offered, once per computer. Trial use is subject to these terms.

2.3 Licence key. Your licence key is personal to the buyer whose email address was used to pay. You must keep it confidential.

3. Restrictions

You must not, and must not allow anyone else to:

  1. reverse engineer, decompile, disassemble, decrypt, or otherwise try to obtain the source code, algorithms, file formats or internal structure of the Software, except to the extent the law or a third-party open-source licence expressly allows it despite this restriction (see Section 9);
  2. modify, adapt, translate, or create derivative works based on the Software;
  3. bypass, disable, patch, emulate or tamper with the licence check, activation, trial limit, machine binding, clock checks, or any other technical protection. This also covers using or sharing tools, keys or cracks that do so;
  4. share, publish, sell, rent, lend or transfer your licence key, or use one key on more computers than your licence allows;
  5. copy, redistribute, re-host or make the Software available to third parties, including as a hosted, network or "software-as-a-service" offering;
  6. remove or alter any copyright, trademark or proprietary notices;
  7. use the Software to build a competing product, or copy its features, interface or templates for that purpose.

4. Enforcement

4.1 Breaching Section 3 ends your licence immediately and without refund, and the Developer may revoke your key remotely.

4.2 Unauthorised copying, distribution, reverse engineering or circumvention of the licence protection may infringe the Developer's copyright. It may also be an offence under the Copyright Act, 1957 (including Sections 63 and 65A) and the Information Technology Act, 2000 (including Sections 43 and 66). The Developer may seek injunctions, damages, account of profits, legal costs, and criminal remedies where available.

4.3 For licence enforcement and abuse detection, the Developer logs licence activity (see Section 7). These logs may be used as evidence.

5. Fees, renewal and refunds

5.1 The licence fee is ₹3,000 per year (inclusive of applicable taxes unless stated otherwise). It is payable through Razorpay at the official payment page.

5.2 To renew, pay again with the same email address. The same key is extended by 12 months.

5.3 Refunds. You may ask for a full refund within 7 days of purchase by replying to your purchase email. After that, fees are non-refundable, except where the law requires otherwise. A refund, chargeback or payment dispute revokes the licence key.

5.4 If the licence expires and is not renewed, the Software stops running new simulations. Your case files and results stay yours and stay accessible.

5.5 Delivery. The Software is delivered digitally. The licence key is emailed automatically within minutes of a successful payment. Nothing is shipped physically.

6. OpenFOAM and third-party software

6.1 FoamStudio is an independent front-end. It does not include, sell or license OpenFOAM. You are responsible for obtaining and using OpenFOAM under its own licence (GNU GPL).

6.2 This offering is not approved or endorsed by OpenCFD Limited, producer and distributor of the OpenFOAM software via www.openfoam.com, and owner of the OPENFOAM® and OpenCFD® trade marks. FoamStudio is likewise not affiliated with The OpenFOAM Foundation.

6.3 The Software includes third-party open-source components. These are listed in Help → About → Third-party licences. Each component is governed by its own licence, and nothing in these terms restricts your rights under those licences.

7. Data and privacy

7.1 To activate and check licences, the Software sends the Developer's licence server:

The server stores these together with your purchase email and payment ID.

7.2 This data is used only to issue licences, enforce seat limits, prevent abuse, send licence and renewal emails, and meet legal and tax obligations. It is not sold. It is processed by service providers the Developer uses: Vercel (hosting), Upstash (database), Razorpay (payments) and Google (email).

7.3 You may ask for access to, correction of, or deletion of your data at shanthoshkv@gmail.com, as provided by the Digital Personal Data Protection Act, 2023. Deleting your data ends your active licence.

7.4 Your simulation data stays on your computers. The Software does not upload it.

8. No warranty: engineering results

8.1 The Software is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied. This includes merchantability, fitness for a particular purpose, accuracy, and non-infringement.

8.2 CFD results depend on the mesh, models, boundary conditions and user judgement. The Software is not certified for, and must not be the sole basis of, safety-critical, structural, aerospace, medical or regulatory decisions. You must independently verify every result before relying on it. Published validation cases show behaviour on those cases only.

9. Statutory rights

Nothing in these terms excludes rights you have under applicable law that cannot be waived by contract. This includes any right to study, observe or test the Software for interoperability or fair dealing, to the narrow extent such law allows. It also includes rights granted by the licence of any open-source component.

10. Limitation of liability

To the maximum extent permitted by law, the Developer is not liable for any indirect, incidental, special, consequential or punitive damages. This includes loss of data, profits, time, computation, or business opportunity, and any damage arising from reliance on simulation results. The Developer's total liability for all claims is limited to the fees you paid in the 12 months before the claim.

11. Updates and availability

Updates may be offered during the paid term. The Developer may change, suspend or discontinue features or the licence service. If the licence service is permanently shut down, the Developer will make reasonable efforts to provide an offline activation method for licences that are still paid up.

12. Termination

This licence ends automatically if you breach these terms, if the term expires without renewal, or if the payment is refunded or disputed. When it ends, you must stop using the Software and uninstall it. Sections 1, 3, 4, 8, 10 and 13 survive termination.

13. Governing law and jurisdiction

These terms are governed by the laws of India. The courts at Bengaluru, Karnataka have exclusive jurisdiction.

14. General

These terms are the entire agreement on the Software. If any provision is found unenforceable, the rest stays in effect. The Developer's failure to enforce a right does not waive it. The Developer may update these terms, and continued use after an update means you accept it. Material changes will be notified by email or in the Software.
