Software Licence

Last updated: 17 October 2026

This is the licence agreement shown when you install the Windows app. It is the same text.

SYSTEM REQUIREMENTS: Windows 64-bit, or a Mac with Apple silicon (M1 or newer). The Mac version does NOT run on Intel Macs.

1. The Licence

Nirmit Pujara, an individual developer in India ("the developer"), grants you a personal, non-exclusive, non-transferable, revocable licence to install and use Duplex AI on your own computers for your own personal or internal business use. The free version needs no payment. Pro features need a Pro licence key, which allows use on ONE computer at a time.

2. What You May Not Do

You may not (a) sell, rent, lend, sublicense or share the software or a Pro licence key; (b) try to bypass or tamper with the licence checks; (c) copy, modify, decompile, reverse-engineer or extract source code from the software, except to the extent the law gives you the right to do so despite this clause; (d) use the software to break the law or to delete files you have no right to delete.

3. Ownership

The software is licensed to you, not sold. The developer keeps all rights in Duplex AI, its name and its logo. Third-party and open-source components included in or downloaded by the software remain under their own licences.

4. You Bear The Risk Of Data Loss

Duplex AI deletes files that YOU choose. The software can make mistakes (including wrong matches), you can make mistakes, and computers can fail. YOU USE THE SOFTWARE AT YOUR OWN RISK AND YOU ALONE BEAR THE RISK OF ANY LOSS OF DATA. Back up anything you cannot afford to lose before you delete it. Deleted files normally go to the Recycle Bin or Trash, but on removable drives, network drives and some cloud-synced folders a deletion can be permanent or can spread to other devices. The developer is not responsible for files that are deleted, changed, lost or damaged, whatever the cause.

5. No Warranty

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF ACCURACY, RELIABILITY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. It is early-stage software and may contain errors.

6. Limit Of Liability

TO THE FULLEST EXTENT THE LAW ALLOWS, THE DEVELOPER IS NOT LIABLE FOR ANY LOSS OF DATA, PROFIT, INCOME OR BUSINESS, OR FOR ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, ARISING FROM THE USE OF OR INABILITY TO USE THE SOFTWARE. THE DEVELOPER'S TOTAL LIABILITY FOR ANY CLAIM IS LIMITED TO THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE 12 MONTHS BEFORE THE CLAIM (AND IS ZERO FOR THE FREE VERSION). Nothing here excludes liability that cannot be excluded by law or removes consumer rights that cannot be waived.

7. Updates, Online Features And Privacy

The software can check for updates and install them with your approval, activate and re-check Pro licences online, and download Pro components and AI model files from third parties. Your files are never uploaded. See the Privacy Policy at the website for details.

8. Termination

You may stop at any time by uninstalling. The developer may end a licence that is used in breach of this agreement. Sections 3 to 6 and 9 continue after termination.

9. Governing Law

This agreement is governed by the laws of India, subject to any mandatory consumer rights where you live.

10. The Rest Of The Terms

The Terms of Use, Privacy Policy and Refund Policy on the Duplex AI website also apply. If they conflict with this agreement about the software licence, this agreement prevails.

This document was written for a small, one-person software project. It is a plain-language agreement, not a substitute for legal advice. If a part of it is found unenforceable, the rest still applies.
