These Terms of Use (“Terms“) govern your use of the “Photos to PDF: Smart Converter” mobile app (listed under that name on the Apple App Store and Google Play; shown in-app as “Photos to PDF“; referred to here as “the App“) on iOS and Android, published by NgheRo.Vn, operated by Cao Vu Hung as an individual household business (Household Business Registration No. 41L8042932, Ho Chi Minh City, Vietnam) (“we“, “us“, “our“). By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. Eligibility

You must be able to form a binding contract to use the App, and you must comply with any minimum age requirements of your app store and applicable law. If you are using the App on behalf of an organization, you represent that you are authorized to bind that organization to these Terms.

2. The App and Its Features

The App lets you capture or import photos and documents, organize and edit pages, and export them as PDF files, with optional on-device OCR (text recognition), local document search, merging, and sharing. Most features work fully offline; certain features (purchase validation, push notifications, support chat, restore purchases) require an internet connection and communicate with our backend. We may add, change, or remove features at any time.

3. User Content and Your Responsibility

“User Content” means the photos, scans, documents, and PDFs you import, capture, or create using the App, plus any messages or files you send us through support chat. You retain all rights to your User Content. You are solely responsible for the User Content you import or create, and you represent that you have the necessary rights to it and that it does not infringe any third party’s rights or violate applicable law (including copyrighted material, other people’s personal data, or unlawful content). Except for content you voluntarily send us (e.g., support chat attachments), the App is designed to keep your User Content on your device, and we do not access, view, or claim ownership of it.

4. Purchases, Subscriptions, and Licenses

The App offers optional paid plans handled through Apple’s App Store or Google Play billing:

  • Lifetime — a one-time, non-consumable purchase that unlocks premium features for as long as you keep an active entitlement on a device (subject to restore-purchase support) tied to your Apple ID/Google Play account.
  • Monthly subscription — an auto-renewing subscription that unlocks premium features for the billing period.
  • Quarterly subscription — an auto-renewing subscription that unlocks premium features for the billing period.

Prices, currency, and any free trial are shown in the App and/or your app store’s product page before purchase and may vary by region. All payments are processed by Apple or Google; we do not collect or store your payment card details. Purchases are validated against our backend, and your entitlement is applied to the App once validation succeeds.

5. Auto-Renewal, Cancellation, and Restore

Monthly and Quarterly subscriptions automatically renew at the end of each billing period unless auto-renewal is turned off at least 24 hours before the end of the current period. Your app store account will be charged for renewal within 24 hours prior to the end of the current period, at the price you agreed to (subject to any price changes we or the app store may communicate in advance, as required by the app store’s policies). You can manage or cancel your subscription, and turn off auto-renewal, at any time in your Apple ID / Google Play account settings — the App itself does not process cancellations. No refund will be given for the unused portion of a subscription period, except as required by Apple’s, Google’s, or applicable law’s refund policies. If you reinstall the App or switch devices, use the “Restore purchases” option to re-apply an active Lifetime unlock or subscription associated with your app store account.

6. Acceptable Use

You agree not to: use the App for any unlawful purpose; attempt to reverse engineer, decompile, or bypass the App’s purchase/entitlement checks; interfere with or disrupt the App or our backend services; upload, via support chat, any content that is illegal, infringing, abusive, or harmful; or use the App in a way that violates Apple’s or Google’s respective platform guidelines.

7. Intellectual Property

The App, including its software, design, graphics, and branding (excluding your User Content and third-party components), is owned by us or our licensors and is protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the App on devices you own or control, for your personal or internal business use, subject to these Terms and any applicable app store terms.

8. Privacy

Our collection and use of information in connection with the App is described in our Privacy Policy, which is incorporated into these Terms by reference.

9. Third-Party Services

The App relies on third-party services, including Apple App Store / Google Play billing, Firebase (Analytics, Crashlytics, Cloud Messaging), and our own backend infrastructure. We are not responsible for the availability, content, or practices of these third-party services, which are governed by their own terms and privacy policies.

10. Disclaimers

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE APP WILL BE ERROR-FREE, UNINTERRUPTED, OR SECURE. ON-DEVICE OCR AND OTHER AUTOMATED PROCESSING MAY BE INACCURATE OR INCOMPLETE, AND YOU SHOULD VERIFY IMPORTANT DOCUMENTS BEFORE RELYING ON THEM.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR REVENUE, ARISING OUT OF OR RELATED TO YOUR USE OF THE APP, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF THESE TERMS OR THE APP WILL NOT EXCEED THE AMOUNT YOU PAID US (IF ANY) FOR THE APP IN THE 12 MONTHS BEFORE THE CLAIM AROSE. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

12. Termination

You may stop using the App at any time by uninstalling it. We may suspend or terminate your access to App features (other than content already stored on your device) if you violate these Terms, misuse the support chat, or attempt to circumvent purchase validation. Sections that by their nature should survive termination (including User Content responsibility, intellectual property, disclaimers, and limitation of liability) will survive.

13. Changes to These Terms

We may update these Terms from time to time. Material changes will be reflected by an updated “Last updated” date above, and where appropriate, an in-app notice. Your continued use of the App after changes take effect constitutes acceptance of the revised Terms.

14. Governing Law

These Terms are governed by the laws of Vietnam, without regard to conflict-of-law principles, reflecting our publisher’s place of business. This does not affect any mandatory consumer-protection rights you have under the laws of your country of residence.

15. Apple App Store Additional Terms

If you downloaded the App from the Apple App Store, the following additional terms apply and take precedence over any conflicting terms in these Terms, solely with respect to your use of the App on Apple-supported devices:

  • These Terms are between you and us only, not Apple, and Apple is not responsible for the App or its content.
  • The license granted to you for the App is limited to a non-transferable license to use the App on an Apple-branded product that you own or control, as permitted by the App Store’s Usage Rules.
  • Apple has no obligation to furnish any maintenance or support services for the App.
  • Apple is not responsible for any product warranties, whether express or implied by law. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App to you; to the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the App.
  • Apple is not responsible for addressing any claims by you or any third party relating to the App, including product liability claims, legal or regulatory compliance claims, or claims arising under consumer protection law.
  • In the event of a third-party claim that the App infringes another party’s intellectual property rights, we, not Apple, are responsible for the investigation, defense, settlement, and discharge of any such claim.
  • You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and are not on any U.S. Government list of prohibited or restricted parties.
  • You must comply with any applicable third-party agreement (e.g., wireless data service agreement) when using the App.
  • Apple, and Apple’s subsidiaries, are third-party beneficiaries of these Terms, and upon your acceptance, Apple has the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
