Terms of Service

1. Scope of the Terms

These Terms are entered into between you and Shanghai Kaichen Era Technology Co., Ltd. (“we,” “us,” or “our”) and apply to your download, installation, access to, or use of Attha software and related services.

Please read these Terms and the Attha Privacy Policy carefully before use. By beginning to use the Software, you acknowledge that you understand and agree to be bound by these Terms. If you do not agree, stop using and uninstall the Software.

2. Services

Attha provides document import, text pasting, document-structure parsing, on-device translation, third-party cloud translation, context-assisted translation, translation history, result export, credential management, and related functions. Actual functions depend on the device platform, operating-system version, Software version, language resources, and availability of third-party services.

We may adjust functions, interfaces, supported formats, the engine catalog, and technical solutions due to product planning, legal requirements, platform rules, or security needs. We will reasonably protect rights you have lawfully acquired, but we do not promise that every function, platform, or third-party engine will remain available permanently.

3. Software License

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to install and use Attha for lawful personal or internal business purposes.

Except where expressly permitted by law or authorized by us in writing, you may not copy, rent, sell, sublicense, publicly distribute, reverse engineer, decompile, or modify the Software, or circumvent its technical protections or usage restrictions.

4. User Content and Responsibility

You retain your existing rights in content that you import, paste, translate, export, or otherwise process. To perform functions you actively select, you authorize the Software to parse, store, transmit, and process that content only as necessary. This authorization does not transfer ownership of the content.

You are responsible for ensuring that you have the right to process relevant documents, subtitles, text, personal information, trade secrets, and other content. You must determine whether translation, cross-border transmission, or submission to a third-party service requires consent from an author, rights holder, data subject, employer, or client.

You are responsible for backing up important documents, translations, and settings. Uninstalling the Software, clearing app data, device damage, system migration, or third-party service failures may make local data unrecoverable.

5. User-Supplied Credentials and Third-Party Services

Certain translation functions require you to provide a third-party API key, account, service region, or other credentials. You are responsible for safeguarding credentials and complying with the provider’s terms, privacy policy, content rules, fees, and regional restrictions.

When you select a cloud engine, the Software follows your instructions to send source segments, limited context, document summaries, terminology, and necessary request parameters to that provider. We do not control the provider’s availability, processing locations, retention periods, outputs, or pricing.

Third-party usage fees are generally settled directly between you and the provider. You are responsible as provided by law for costs and losses caused by exposed keys, exhausted quotas, account restrictions, region settings, nonpayment, or violations of third-party rules, except where we are legally liable.

6. Fees, Purchases, and Updates

Whether the Software is paid, and its pricing, license scope, and discounts, are governed by the download page, in-app disclosures, or listings in the Apple App Store, Google Play, Microsoft Store, or another distribution platform. Purchases, refunds, taxes, and renewals completed through a third-party platform are subject to that platform’s rules and mandatory law.

Software updates may fix defects, adjust compatibility, or change functions. To protect security and availability, we may require you to upgrade to a supported version.

7. Prohibited Conduct

You may not use Attha to:

• create, process, transmit, or distribute illegal content;

• process another person’s personal information, trade secrets, copyrighted content, or other protected information without authorization;

• impersonate, defraud, or harass another person, infringe lawful rights, or use translations for unlawful decisions or activities;

• crack, decompile, modify, attack, or interfere with the Software, provider interfaces, or related systems; or

• bypass access controls, maliciously consume API quotas, abuse services at scale, or help another person do any of the above.

8. Intellectual Property

Attha’s names, logos, interfaces, code, documentation, visual design, technical solutions, and related intellectual property belong to us or the relevant rights holders. Third-party translation engines, trademarks, models, and services belong to their respective rights holders.

These Terms do not grant you a right to use our or a third party’s trademarks, trade names, domain names, or other brand identifiers.

9. Translation Outputs and Disclaimers

Translation outputs may be affected by source quality, language pairs, context, terminology, device capabilities, model behavior, network conditions, and third-party service changes. They may contain errors, omissions, ambiguities, inappropriate content, or formatting deviations. You should review outputs before using, publishing, or acting on them.

Attha and its translation outputs do not constitute medical, legal, financial, certification, notarization, or other professional advice and should not be the sole basis for a high-risk decision.

To the extent permitted by law, the Software is provided on an “as is” and “as available” basis. For interruptions or losses caused by force majeure, network failures, system compatibility, third-party service interruption, platform policies, user configuration, or other matters outside our reasonable control, we are liable only to the extent required by law. Nothing in this section excludes or limits liability that cannot lawfully be excluded or limited.

10. Privacy

We process relevant personal information under the Attha Privacy Policy. Before selecting a third-party cloud engine, also review that provider’s privacy policy and confirm that its data processing meets your needs and obligations.

11. Suspension and Termination

You may stop using and uninstall the Software at any time. If you materially violate these Terms, infringe another person’s rights, threaten system security, or if the law requires us to act, we may restrict or terminate relevant functions to the extent reasonably necessary and reserve the right to pursue remedies under law.

Termination does not affect rights and obligations accrued before termination or provisions that by their nature should survive, including intellectual-property, limitation-of-liability, and dispute-resolution provisions.

12. Changes to these Terms

We may update these Terms due to changes in laws, platform requirements, or the product. For material changes, we will provide notice through the Software, website, or another appropriate method. Your continued use after the update takes effect means you accept the updated Terms. If you do not agree, stop using the Software.

13. Governing Law and Dispute Resolution

These Terms are governed by the laws of the People’s Republic of China. Disputes arising from these Terms or Attha should first be resolved through friendly consultation. If consultation fails, either party may bring an action before a competent court at the domicile of Shanghai Kaichen Era Technology Co., Ltd., unless mandatory law provides otherwise.
