Karatu

Terms of Use

Dexino Cloud & AI Solutions · Mobile Apps · Terms

These Terms of Use govern your use of Karatu, a reading and listening application developed by Dexino Cloud & AI Solutions.

1. Acceptance of these Terms

By downloading, installing or using Karatu, you agree to these Terms of Use.

If you do not agree with these Terms, you should not use the application.

2. Purpose of Karatu

Karatu is a document reading, listening and library-management application that may provide features including PDF and EPUB reading, text-to-speech, audiobook playback, reading-position memory, book-cover management and related functionality.

Karatu is provided as a tool. Dexino does not supply or grant rights to third-party books, documents or other copyrighted material that a user chooses to open with the application.

3. User content and responsibility

Users may choose to open or import documents, books, images, audio or other supported content into Karatu.

Users remain responsible for ensuring that they possess the necessary ownership rights, licences, permissions or other lawful basis to access, copy, process, display, listen to or otherwise use such content.

Dexino does not claim ownership of content that users choose to open, import or manage with Karatu.

The presence of technical functionality capable of opening or processing a file does not constitute permission from Dexino to use that file unlawfully.

4. Copyright and lawful use

Karatu is intended for use with legally obtained and lawfully accessible material.

Users must not use Karatu to knowingly infringe copyright, intellectual-property rights, privacy rights or other legal rights of third parties.

Users must not use Karatu to obtain, distribute or knowingly process content where doing so would violate applicable law.

Dexino does not encourage or support piracy, copyright infringement, unauthorised distribution of protected works or the use of unlawfully obtained documents.

5. Prohibited use

Users must not use Karatu:

• for unlawful, fraudulent or intentionally abusive purposes;
• to knowingly infringe intellectual-property or privacy rights;
• to distribute content that the user has no legal right to distribute;
• to circumvent digital-rights-management systems, access controls or other technological protection measures;
• to interfere with, reverse engineer or misuse Karatu except where such activity is expressly permitted by applicable law;
• to attempt to compromise the security, integrity or operation of Karatu or related services.

6. Local files and privacy

Karatu is designed primarily as a local-first application.

Users are responsible for maintaining backups of important books, documents, reading data and other files stored on their devices.

Dexino cannot guarantee recovery of locally stored user content if a device is lost, damaged, reset, replaced or if application data is deleted.

Information about Karatu's handling of information is available in the Karatu Privacy Policy.

7. Third-party services

Certain Karatu features may rely on or interact with third-party services, including Google Play, Google Mobile Ads, Google Books, Open Library, Android system services or other external providers.

Third-party services are governed by their own terms, availability and privacy practices.

Dexino is not responsible for changes, interruptions, restrictions or content provided independently by third-party services.

8. Online book-cover search

Karatu may provide functionality that allows users to search external book-information services for cover artwork.

Search results and cover images are supplied by third-party sources. Dexino does not guarantee the accuracy, availability, ownership status or suitability of every third-party image returned by those services.

Users remain responsible for using third-party images in a manner consistent with applicable rights and laws.

9. Advertising

The free version of Karatu may display advertisements provided by Google or other advertising services used by Dexino.

Advertising availability, format and personalisation may vary according to location, device configuration, applicable law and the advertising provider's settings.

Dexino does not guarantee that advertisements will always be available or that advertising services will remain unchanged.

10. Purchases and removal of advertisements

Karatu may offer an optional one-time in-app purchase to remove advertisements.

Purchases are processed through Google Play and are associated with the user's Google Play account according to Google's purchasing systems and policies.

Dexino does not directly process or store users' complete payment-card information.

Refunds, cancellations and purchase disputes are handled in accordance with Google Play policies, applicable consumer law and, where appropriate, Dexino's responsibilities as the application developer.

Restoration or recognition of a previous purchase may depend on the Google account used for the original transaction and the availability of Google Play services.

11. Application availability and changes

Dexino may update, modify, add, remove or discontinue Karatu features when reasonably necessary for technical, security, legal, commercial or product-development reasons.

Dexino does not guarantee that every feature will remain permanently available or function identically on every Android device, operating system version or third-party service.

12. Text-to-speech and automated processing

Text-to-speech output, document extraction, OCR or other automated processing may occasionally produce incorrect, incomplete or unexpected results.

Users should not rely on Karatu's automated output as an authoritative substitute for the original document where accuracy is important.

Karatu is not intended to provide legal, medical, financial or other professional advice.

13. Intellectual property in Karatu

Karatu, its software, interface, branding, original graphics, application design and related Dexino materials are owned by or licensed to Dexino Cloud & AI Solutions and are protected by applicable intellectual-property laws.

These Terms do not transfer ownership of Karatu or Dexino intellectual property to users.

14. Disclaimer of warranties

To the extent permitted by applicable law, Karatu is provided on an "as available" basis.

Dexino does not guarantee uninterrupted operation, compatibility with every file, device or service, or that every document will be processed without errors.

Nothing in these Terms excludes warranties, rights or remedies that cannot lawfully be excluded under applicable consumer-protection law.

15. Limitation of liability

To the extent permitted by applicable law, Dexino is not responsible for indirect or consequential loss arising solely from the use or inability to use Karatu, third-party services or user-provided content.

Users remain responsible for maintaining appropriate backups of important documents and data.

Nothing in these Terms limits liability where such limitation would be prohibited by applicable law, including mandatory consumer protections.

16. Suspension or misuse

Dexino may take reasonable measures to protect Karatu, its distribution channels or associated services against fraud, abuse, security threats or unlawful activity.

Where Karatu does not require a Dexino account, this does not give Dexino access to or control over files stored locally on the user's device.

17. Changes to these Terms

These Terms may be updated when Karatu's functionality, business model, third-party services or legal requirements change.

The current version will be published on this page and identified by the "Last updated" date below.

18. Governing law

To the extent permitted by applicable law, these Terms are governed by the laws of Switzerland.

Mandatory consumer-protection rights applicable in a user's country or place of residence remain unaffected.

Where legally permitted, disputes relating to Karatu or these Terms are subject to the competent courts at the registered place of business of Dexino Cloud & AI Solutions, unless mandatory law provides otherwise.
