QR Hub : Terms of Use & Service

By downloading, installing, accessing, or using QR Hub : Ultimate QR & Barcode Studio (Application ID: com.qr.hub), developed and published by Krishna Tech Hub, you signify your unreserved agreement to these Terms of Use and our companion Privacy Policy.

If you do not agree to each and every provision set forth in this document, you must discontinue using and uninstall the application immediately.

Krishna Tech Hub grants you a personal, revocable, non-exclusive, non-transferable, royalty-free license to use QR Hub on compatible Android devices running Android 7.0 (API Level 24) or higher:

• ✔
  Commercial Output Freedom: You retain complete ownership and full commercial distribution rights over any QR code artwork, barcode sticker layouts, or PDF sheets generated using QR Hub.
• 🚫
  Reverse Engineering Prohibited: You may not decompile, reverse engineer, disassemble, deobfuscate, modify, or attempt to derive the underlying source code of QR Hub.
• 🚫
  No Malicious Generation: You may not use the generator tools in QR Hub to synthesize malicious payloads, phishing URLs, exploit delivery triggers, or fraudulent payment deceptive codes.

All barcode decoding calculations and history logs are managed inside your device's isolated Android Room SQLite database.

Krishna Tech Hub does not operate centralized user servers to ingest or review your scan history or customized QR assets. You remain exclusively responsible for backing up your scan records (via the in-app CSV export feature) and managing your local storage.

QR Hub is offered free of charge worldwide. To offset development and maintenance costs, the app incorporates third-party advertising SDKs, notably Google AdMob.

Third-party providers operate strictly within standard sandboxed Android runtime boundaries and are governed by their own terms and privacy disclosures. We maintain verified compliance via our crawler record:

QR Hub is provided on an "AS IS" and "AS AVAILABLE" basis 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.

While the app utilizes Google ML Kit to maximize scanning precision, Krishna Tech Hub is not liable for:

• Damages or security risks resulting from navigating to external URLs or third-party web domains encoded in third-party QR codes.
• Financial losses arising from unverified UPI / banking QR payment redirects initiated outside the app's control.
• Hardware damage, battery consumption, or data loss occurring during intensive batch scanning or PDF rendering operations.

Krishna Tech Hub reserves the right to modify, amend, or update these Terms of Use at any time. Any changes will become effective immediately upon publication on this website with an updated revision date. Your continued use of QR Hub following the posting of modifications indicates your binding acceptance of the updated Terms.
