Software License

Last updated: August 6, 2026

This Agreement governs your installation, purchase, activation, and use of LocalMask. By installing, purchasing, activating, or using the software, you agree to this Agreement and the separately available Privacy Policy. If you do not agree, do not use the software.

1. Provider and product

LocalMask is provided by Nanjing Lingxin Technology Co., Ltd., Nanjing, Jiangsu, China. It is a desktop application for local recognition, masking, replacement, and redaction of sensitive information in supported documents and images.

Redaction runs locally and offline. LocalMask does not send original documents, recognition results, or redacted outputs to servers operated by us or any third party.

2. License grant

Subject to this Agreement, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable right to use LocalMask on properly licensed devices for lawful personal or internal business purposes. The applicable license mode, device count, term, eligible versions, and functions are determined by your purchase, license payload, or separate written agreement.

3. Offline licenses

A single-device offline license is normally bound to the machine code used when it is issued. It does not require recurring verification with our licensing server. A perpetual offline license permits continued use only of versions covered by its maintenance cutoff and other license conditions.

Because an offline license cannot normally be revoked, frozen, or invalidated remotely after delivery, you must confirm the machine and license terms before issuance and keep the license material secure. Refund, replacement, migration, or cancellation rights are governed by the purchase page, order terms, applicable law, and any separate written agreement.

4. Enterprise licenses

The seats, term, online requirements, device administration, service scope, and other rights and obligations for enterprise licensing are governed by the contract or other written agreement separately entered into by the parties.

5. Your responsibilities and restrictions

You must keep license materials and account credentials confidential. You may not share, resell, sublicense, rent, lend, or transfer them to an unauthorized party.

Except where applicable law expressly permits otherwise, you may not reverse engineer, decompile, disassemble, bypass or interfere with licensing or integrity controls, remove ownership notices, distribute modified copies, or use LocalMask to violate law, contracts, privacy, confidentiality, intellectual-property, or other third-party rights.

You are responsible for ensuring that you have a lawful basis to process documents and for reviewing redaction results before external submission, disclosure, filing, or use in a legal, regulatory, medical, financial, or other consequential process.

6. Intellectual property

LocalMask, including its interface, code, algorithms, rules, models, documentation, branding, and structure, is owned by us or the relevant rights holder. This Agreement grants only a limited license and does not transfer ownership. Third-party open-source components remain subject to their applicable licenses.

7. Data and privacy

Redaction is local. LocalMask does not send original documents, recognition results, redacted outputs, redaction settings, or related business content to servers operated by us or any third party.

To provide licensing, support, security auditing, and abuse prevention, we process necessary licensing information. License checks do not upload original documents, recognition results, or redacted outputs. Licensing information is not used for unrelated advertising profiles. Details about information types, processing, visibility, retention, and individual rights are set out in the Privacy Policy.

8. Product behavior and updates

Supported formats, recognition behavior, redaction functions, and interface details may change as the product develops. Updates do not expand the scope of an existing license beyond its applicable maintenance period or other license conditions unless separately stated.

9. No professional advice

LocalMask is a redaction and anonymization tool. It does not provide legal, compliance, audit, medical, financial, security, judicial, or regulatory advice and does not replace professional or human review.

10. Warranty disclaimer

The software is provided "as is" and "as available." To the maximum extent permitted by applicable law, we do not warrant uninterrupted or error-free operation, complete compatibility, absolute security, or detection and redaction of every sensitive item.

11. Limitation of liability

To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, consequential, special, or punitive damages, lost profits, lost data, business interruption, or failure to detect every sensitive item. Where liability cannot be excluded, our aggregate liability is limited to the amount you paid for the relevant license, except where applicable law prohibits that limitation.

12. Termination and changes

If you materially breach this Agreement, we may terminate or restrict the license and require you to stop using the software and license materials. Terms that by their nature should survive termination remain effective.

We may update this Agreement for product, business, or legal changes. Updated terms may be displayed through the website, checkout, app, documentation, or another reasonable channel. Continued use after an effective update constitutes acceptance to the extent permitted by applicable law.

13. Governing law and contact

This Agreement is governed by the laws of the People's Republic of China. Disputes should first be discussed in good faith; unresolved disputes may be submitted to a court with jurisdiction at the location of Nanjing Lingxin Technology Co., Ltd.
