Terms of Use

1. Service and use

PaperIn is provided by Luoyang Shuanglei Network Technology Co., Ltd. It offers document scanning, image adjustments and PDF/image export on iOS. Features, supported devices, trial limits and pricing depend on the App Store version and in-app information.

Only process materials you are entitled to use, and respect applicable law, intellectual property and others’ privacy. You retain rights to your documents. Using the app does not transfer document ownership to us.

2. Purchases and license

If a version offers a one-time unlock or other in-app purchases, the price, entitlements and conditions are shown before purchase. Apple handles payment and refunds. Restoration depends on the Apple account, product type and applicable store rules. The software license is governed by Apple’s Standard End User License Agreement (EULA). This page supplements how the service is used and does not replace that license.

3. Files and responsibility

Automatic cropping, enhancement and compression may affect readability or appearance. Check exports before sharing, printing or relying on them for important matters, and retain originals and backups. The app provides no legal, medical or other professional determination and does not guarantee that a scan has the same legal effect as an original.

System changes, device limitations or faults may change or interrupt the service. We remain responsible as required by applicable law. These terms do not exclude or limit non-waivable consumer rights or liabilities.

4. Privacy, updates and contact

See the Privacy Policy for data handling. We update this page for material changes and provide separate notice where legally required. Applicable law and Apple’s standard EULA govern matters not addressed here. Contact: service@lydoublelei.com.
