Privacy Policy

Last updated: August 6, 2026

This Privacy Policy explains how Nanjing Lingxin Technology Co., Ltd. ("we") handles information through the LocalMask website, checkout, license delivery, offline activation, and support.

1. Information we process

- Purchase and offline-license information: email address, machine code, payment method, order and transaction identifiers, payment status, license type and status, activation or license credentials, checkout IP address, and approximate network location.
- Support information: contact details, device information, log excerpts, screenshots, file samples, issue descriptions, and communications that you voluntarily send for sales, support, or troubleshooting.
- Website and download statistics: page path, query parameters, referrer, UTM parameters, download platform and language, IP address, approximate network location, user agent, timestamp, and information you voluntarily enter in an optional download inquiry form, such as company name and use case.
- Security and operational logs: request time and path, source IP address, user agent, response status, and necessary error information.

2. How and why we use information

LocalMask performs redaction locally and offline on your device. The app does not send original documents, recognition results, redacted outputs, redaction settings, or related business content to servers operated by us or any third party.

We process information to create and confirm orders; issue and deliver licenses; provide support; troubleshoot incidents; protect licensing systems against fraud and abuse; improve website, download, and purchase flows; and meet contractual, accounting, tax, audit, dispute, and legal obligations.

We limit processing to what is reasonably necessary for these purposes.

3. Only when enterprise licensing is used

- Enterprise licensing requires periodic online checks. The app sends the enrollment code, machine identifier, the user or device label entered in the app, and, where available, operating system, CPU architecture, and app version. It also sends enterprise and device identifiers and necessary licensing credentials for device applications and license verification.
- Enterprise licensing processes the enterprise name, seat limit and term, device status, latest license check, enterprise administrator login name and latest login time, and necessary licensing audit records.
- Your organization's administrator can view the device label, machine code, operating system, CPU architecture, app version, status, application time, and last-seen time, and can approve, reject, disable, or re-enable devices. Do not place unrelated personal information in a device label.
- Authorized LocalMask personnel access this information only where needed for license administration, support, security auditing, or prevention of license abuse.
- Enterprise, administrator, device-status, and licensing-audit records are kept while the enterprise license relationship continues and for the shortest additional period needed for support, security audits, disputes, and prevention of license abuse.
- Enterprise-license requests do not upload documents, recognition results, or redacted outputs, and licensing information is not used for unrelated advertising profiles. Enterprise device information is normally managed by your organization's administrator, but you may also contact us directly to exercise applicable privacy rights.

4. Service providers and disclosures

When you use a third-party payment service, we may exchange necessary order, payment-status, transaction, refund, tax, or reconciliation information with that provider. We may provide an IP address to an IP-geolocation provider to obtain an approximate network location. Hosting, email-delivery, and other infrastructure providers may process information as our service providers where needed to operate the service.

We do not sell personal information. We do not disclose personal information to unrelated third parties unless required by law, needed to deliver payment or licensing services, or separately authorized by you.

5. Retention

Order, payment, offline-license, and issuance records are kept for the shortest period needed for transactions, license verification, support, accounting, tax, audit, dispute handling, and legal obligations. Security and operational logs and business statistics are retained only as long as needed to protect the service, analyze product delivery, handle disputes, and prevent abuse, unless law requires otherwise. Support materials that you voluntarily provide are retained only as long as needed for support, troubleshooting, or compliance.

When retention is no longer necessary, we delete or anonymize information, or restrict processing to storage and required security protection where deletion is not yet legally or technically available.

6. Security

We use reasonable access controls, permission management, encrypted transport, logging, and other technical and organizational safeguards. No system is completely secure. Keep authorization materials, account credentials, and lookup credentials confidential.

7. Your rights and choices

Subject to applicable law, you may request access, a copy, correction, supplementation, or deletion of your personal information, or ask us to explain our processing rules. Some information may need to be retained for contractual, accounting, tax, audit, fraud-prevention, dispute, or legal reasons.

Where processing relies on consent, you may withdraw consent. Withdrawal does not affect earlier processing but may prevent us from continuing some purchase, licensing, support, or related services. Contact us to exercise these rights or raise a privacy question or complaint.

8. Children

LocalMask and its purchasing services are primarily intended for users with legal capacity to enter into transactions. A minor should purchase, activate, or use LocalMask only with a guardian's consent and guidance.

9. Updates

We may update this Policy when product functions, business processes, or legal requirements change. Updated terms will be made available through the website, checkout, app, documentation, or another reasonable channel. Material changes will be highlighted where reasonably appropriate.
