Terms of Service — PDF Reader Pro Edition

Effective date: July 14, 2026

Who we are: iTech Development Systems Inc. ("iTech", "we", "us"), USA.

These Terms of Service (the "Terms") govern your use of the PDF Reader Pro Edition application (the "App") and the website pdf-app.com (the "Site"). By downloading or using the App or Site, you agree to these Terms. If you do not agree, do not use the App.

1. License to use the App

We grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the App on Apple devices that you own or control, for your personal or internal business purposes, in accordance with these Terms and the App Store Terms of Service. We do not sell the App to you; we license it.

You may not: copy, modify, or distribute the App; reverse engineer or attempt to extract its source code except where such restriction is prohibited by law; rent, lease, or sublicense the App; or use the App to build a competing product.

2. Your documents and content

Your documents belong to you. The App is designed to process your documents on your device: reading, editing, annotation, conversion, text recognition, and AI features run locally, and we operate no servers that receive or store your documents. You retain all rights to your content, and these Terms grant us no ownership of it.

You are solely responsible for your documents — including having the rights to use and edit them, complying with applicable law, and keeping backups. The App's features (including iCloud sync, if you enable it) are not a substitute for your own backup practices.

3. Accounts

Creating an account is optional and required only for certain features (such as library synchronization). You agree to provide accurate information, keep your credentials secure, and notify us of any unauthorized use. You may delete your account at any time in the App (Settings → Account); deletion is permanent. We may suspend or terminate accounts that violate these Terms.

4. Subscriptions and purchases

Some features require a paid subscription ("PRO"). Subscriptions are sold and processed by Apple through your App Store account:

Auto-renewal. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Your App Store account is charged for renewal within 24 hours before the period ends.

Managing and cancelling. You can manage or cancel your subscription anytime in your device's Settings → Apple Account → Subscriptions, or in the App via Settings → Premium. Cancelling stops future renewals; you keep access until the end of the paid period.

Refunds are handled by Apple under App Store policies; we cannot issue App Store refunds directly. To request one, visit reportaproblem.apple.com.

Price changes will be communicated as required by App Store rules; if you do not agree, you may cancel before the change takes effect.

Free trials or introductory offers, where available, convert to a paid subscription unless cancelled before the trial ends.

5. Third-party services you connect

The App can optionally connect to services such as iCloud, Google Drive, Dropbox, Box, and Microsoft OneDrive. Your use of those services is governed by their own terms and privacy policies, and you are responsible for complying with them. We are not responsible for the availability, accuracy, or operation of third-party services, and connecting them is at your option and risk. Documents transfer directly between your device and the service.

6. AI features

The App includes AI-powered features (such as document chat, summaries, library search, and translation) that run on your device using Apple's on-device machine-learning technologies. AI-generated output may be inaccurate, incomplete, or outdated. It is provided for convenience only and is not professional, legal, medical, financial, or tax advice. Always verify important information against the original document. You are responsible for how you use AI-generated output.

7. Acceptable use

You agree not to use the App or Site to: violate any law or the rights of others; process content you have no right to use; attempt to gain unauthorized access to any system; interfere with the operation of the App or Site; or misuse any feature (including cloud connections and AI features) in a way that harms us, other users, or third parties.

8. Intellectual property

The App, Site, and all related software, designs, text, graphics, logos, and trademarks are owned by iTech or its licensors and are protected by intellectual-property laws. Except for the license in Section 1, nothing in these Terms grants you any rights to our intellectual property. Feedback you send us may be used without obligation to you.

If you believe content on our Site infringes your copyright, contact support@itechdevelopmentsystems.com.

9. Privacy

Our Privacy Policy explains what information we collect and how we use it, and forms part of these Terms.

10. Disclaimers

THE APP AND SITE ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT DOCUMENT CONVERSIONS, TEXT RECOGNITION, OR AI OUTPUT WILL BE ACCURATE OR COMPLETE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, ITECH WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, PROFITS, OR BUSINESS, ARISING FROM OR RELATED TO YOUR USE OF THE APP OR SITE. OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE OR (B) FIFTY US DOLLARS (US $50).

NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED UNDER APPLICABLE LAW, INCLUDING, FOR CONSUMERS IN THE EUROPEAN UNION AND UNITED KINGDOM, STATUTORY CONSUMER RIGHTS AND LIABILITY FOR INTENT OR GROSS NEGLIGENCE WHERE SUCH LIABILITY CANNOT BE LIMITED.

12. Indemnification

You agree to indemnify and hold iTech harmless from claims, damages, and expenses (including reasonable attorneys' fees) arising from your content, your use of the App in violation of these Terms, or your violation of law or third-party rights.

13. Apple-specific terms

These Terms are between you and iTech only — not with Apple Inc. ("Apple"). Apple is not responsible for the App or its content. Apple has no obligation to provide maintenance or support for the App. In the event of any failure of the App to conform to an applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App (if any) to you; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App. Apple is not responsible for addressing any claims relating to the App or your use of it, including product-liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer-protection or similar legislation. In the event of a third-party claim that the App infringes intellectual-property rights, iTech, not Apple, is responsible for its investigation, defense, settlement, and discharge. You represent that you are not located in a country subject to a U.S. government embargo and are not on any U.S. government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

14. Termination

You may stop using the App at any time. We may suspend or terminate your access (including your account) if you materially breach these Terms, if required by law, or if we discontinue the App. Sections that by their nature should survive termination (including Sections 2, 8, 10, 11, and 12) survive.

15. Changes to the App and these Terms

We may modify, add, or remove features of the App over time. We may update these Terms; if we make material changes, we will provide notice on the Site or in the App before they take effect. Your continued use after the effective date constitutes acceptance. If you do not agree to updated Terms, stop using the App and cancel any subscription.

16. Governing law and disputes

These Terms are governed by the laws of the State of [INSERT STATE, e.g. Delaware], USA, without regard to conflict-of-law rules. Disputes will be resolved in the state or federal courts located in [INSERT COUNTY/STATE], and you consent to their jurisdiction. If you are a consumer in the EU or UK, you retain any rights to bring proceedings in, and benefit from the mandatory consumer laws of, your country of residence.

17. General

If any provision of these Terms is found unenforceable, the rest remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms; we may assign them in connection with a merger or sale. These Terms, together with the Privacy Policy, are the entire agreement between you and iTech regarding the App and Site.
