Kilovoice Terms of Use

Version: V1.0.0 Last Updated: August 4, 2026 Effective Date: August 4, 2026

Important Notice

Welcome to Kilovoice.

Please read these Terms carefully before using the App or Services, particularly the provisions concerning lawful recording, subscriptions, AI-generated content, limitations of liability, termination, governing law, and dispute resolution. Nothing in these Terms excludes or limits liability or consumer rights where doing so is prohibited by applicable law.

When you affirmatively select the consent option and tap “Agree,” “Continue,” or another button with equivalent meaning, you acknowledge that you have read, understood, and agreed to these Terms, the Privacy Policy, and any applicable Membership Payment Agreement incorporated by reference. We will not infer consent merely because you continue browsing or using the Services. If you do not agree, do not use the Services.

1. Operator and Contact Details

  1. “we,” “us,” “our,” or “Operator” means the entity providing Kilovoice and the related Services:
    • Legal name: Top Stack Technology Co., Ltd.
    • Chinese legal name: 合肥栈顶信息科技有限公司
    • Support email: kilovoice@top-stack.com
  2. Questions, complaints, and claims concerning the App, Services, accounts, or these Terms may be sent using the contact details above.

2. Scope of These Terms

  1. These Terms apply to the Kilovoice iOS application, future versions of the application, and related websites, cloud processing, and support services expressly made subject to these Terms.
  2. The Privacy Policy explains how we process personal data. The Membership Payment Agreement explains subscriptions, automatic renewal, and membership benefits. Those documents form part of your agreement with us.
  3. If product-specific terms conflict with these Terms, the product-specific terms will control for that subject matter, but they will not reduce any mandatory consumer rights.
  4. If the App is obtained through the Apple App Store, the Apple Media Services Terms, App Store Usage Rules, and other applicable Apple terms also apply.

3. Eligibility and Children

  1. You must have legal capacity to enter into these Terms. If you are below the age at which you may independently consent under the law where you live, a parent or legal guardian must review and agree to these Terms and supervise your use.
  2. The Services are not directed to children under 14 in Mainland China or children under 13 in the United States. We do not knowingly collect personal data requiring consent from such children without valid parental or guardian consent.
  3. If we learn that a user is below the applicable age and valid consent has not been obtained, we may restrict or terminate the Services and process the relevant data as required by law.
  4. Parents and guardians should help minors comply with recording, privacy, data protection, intellectual property, and online-content laws.

4. Anonymous Identity, Accounts, and Sign-In

  1. Signing in is not required to record, import, or view local content.
  2. When you are signed out, we may associate your free allowance, membership benefits, recordings, imported files, and processing tasks with a device-linked pseudonymous identifier. You are responsible for securing your device and system credentials.
  3. You may choose Sign in with Apple. After a successful sign-in, we may bind or migrate data and valid benefits associated with the current anonymous identifier to your account in accordance with the product rules.
  4. You must not impersonate another person, use another person’s account without authorization, or use technical means to create, sell, rent, lend, or trade accounts or anonymous identifiers.
  5. Notify us promptly at the support email if you suspect unauthorized use.
  6. Signing out does not delete data already linked to your account and does not cancel an Apple subscription. Account deletion and subscription cancellation are separate actions.

5. Services

Depending on device, region, language, and network availability, the Services may include:

  1. live recording, pause, resume, saving, and playback;
  2. local audio import;
  3. audio upload, speech-to-text transcription, speaker separation, AI titles, summaries, and action items;
  4. in-meeting notes, transcript editing, folders, search, sharing, and export;
  5. free allowances, memberships, restoration of purchases, and account management; and
  6. other features we may make available.

Some features require microphone, speech recognition, notification, network, storage, or other system permissions. Refusing an optional permission should not prevent use of unrelated core features. A feature that depends on a necessary permission may not function without it.

6. Lawful Recording and Audio Use

  1. Recording, interception, telephone and meeting audio, trade secrets, personal data, and cross-border transfers are regulated differently around the world. Some jurisdictions require advance consent from every person recorded.
  2. Before recording, importing, uploading, transcribing, sharing, or exporting content, you must:
    • confirm that you have the legal right to do so;
    • provide all notices and obtain all consents required by applicable law;
    • comply with workplace, school, event-organizer, and venue rules; and
    • avoid recording state secrets, trade secrets, health information, financial account data, or other specially protected information unless you have a lawful basis and appropriate safeguards.
  3. You must not use the Services for unlawful surveillance, stalking, harassment, blackmail, fraud, discrimination, defamation, invasion of privacy, intellectual-property infringement, obstruction of justice, or any other unlawful purpose.
  4. The App is a general-purpose recording tool. It does not replace your assessment of whether a recording is lawful, and technical availability does not mean that recording is lawful where you are.
  5. You are legally responsible for consequences caused by your failure to provide notice, obtain consent, or otherwise use recordings lawfully. This does not exclude any liability that we must bear under applicable law.

7. User Content and Limited License

  1. As between you and us, you retain the rights you hold in audio, transcripts, notes, titles, and other content that you lawfully record, upload, edit, or generate.
  2. To provide the Services, you grant us a non-exclusive, worldwide, royalty-free, limited license, exercisable by necessary service providers, solely to host, transmit, reformat, transcribe, summarize, synchronize, back up, display, export, secure, and otherwise process content according to your instructions. This license lasts only as long as reasonably necessary to provide the Services.
  3. Unless we separately and clearly notify you and obtain any consent required by law, we will not use identifiable private recordings or transcripts to train general-purpose AI models offered to the public.
  4. You represent that you have the rights required to submit content and that it does not infringe privacy, data protection, publicity, reputation, copyright, trade secret, or other rights.
  5. Once you share or export content, a recipient’s processing may be outside our control. Verify recipients and content scope before sharing.

8. AI Transcription and Generated Content

  1. Transcripts, speaker labels, titles, summaries, and action items are generated using automated technologies and may contain omissions, misrecognitions, incorrect attribution, bias, or incomplete information.
  2. AI output is provided as an aid for note-taking and reference. It does not replace original audio, human review, or legal, medical, financial, safety, or other professional advice.
  3. You should verify output against the original audio before relying on it, publishing it, sharing it, or taking action based on it.
  4. Network conditions, accents, language, background noise, overlapping speakers, and audio quality may affect results.
  5. To the extent permitted by law, we do not guarantee that AI output will be completely accurate or fit for a particular purpose. We will nevertheless provide reasonable error handling, retries, and consumer remedies as required by law and these Terms.

9. License and Restrictions

  1. Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to use the App on Apple-branded products that you own or control, as permitted by the Apple Media Services Usage Rules and applicable law.
  2. Except where applicable law expressly permits it, you may not:
    • copy, sell, rent, sublicense, redistribute, or commercially provide the App;
    • reverse engineer, decompile, disassemble, derive source code, bypass technical protections, modify, or create derivative works;
    • interfere with the Services, probe vulnerabilities, introduce malicious code, or bypass allowance or subscription verification;
    • use automation for abusive access, scraping, or bulk processing; or
    • remove or alter proprietary notices.
  3. All rights not expressly granted are reserved by us and our licensors.

10. Free Services and Membership Subscriptions

  1. Free allowances, membership benefits, billing periods, prices, trial periods, and promotions are shown on the purchase screen and App Store confirmation screen.
  2. The current product design provides non-members with a combined cumulative 30-minute allowance for recording and imported-audio processing; final benefits will be disclosed on the released purchase screen. When the cumulative limit is reached:
    • an active recording will automatically stop and be saved;
    • new recordings and new audio imports will be paused until the user obtains a new valid allowance or membership benefit; and
    • saved audio and completed processing results will remain viewable, except where law requires otherwise or the user deletes content or the account.
  3. For subscriptions purchased through the Apple App Store:
    • Apple processes payment and manages the transaction;
    • an auto-renewing subscription renews for the period and price shown on the App Store confirmation screen;
    • unless canceled at least 24 hours before the end of the current period, or within another period required by Apple or local law, the subscription may automatically renew;
    • you can manage or cancel it in your Apple ID subscription settings; and
    • deleting the App, signing out, or deleting your App account does not cancel the subscription.
  4. Prices, taxes, currencies, trial eligibility, and renewal prices are determined by the App Store display. Price changes will be notified or submitted for consent as required by Apple and applicable law.
  5. Refunds are processed by Apple under its refund procedures, without prejudice to mandatory refund, withdrawal, or remedy rights under applicable law.
  6. If membership benefits are not correctly linked, use “Restore Purchases” or contact support. We may request a necessary transaction identifier, but we will never ask for your Apple ID password.
  7. Additional payment terms appear in the Membership Payment Agreement. In a conflict with the App Store confirmation screen, applicable law and the validated App Store transaction record will control.

11. Privacy and Data Protection

  1. We process personal data under the Privacy Policy and applicable data-protection laws, including, where applicable, Mainland China’s Personal Information Protection Law, Cybersecurity Law and Data Security Law, the GDPR, CCPA/CPRA, COPPA, and similar laws.
  2. The Privacy Policy describes processing of recordings, transcripts, account data, device identifiers, transaction receipts, diagnostics, and international transfers.
  3. Depending on applicable law, you may have rights of access, copy, correction, deletion, withdrawal of consent, restriction, objection, portability, and account deletion.
  4. If these Terms conflict with the Privacy Policy regarding personal-data processing, the Privacy Policy and applicable law will control.

12. Third-Party Services

  1. The Services may use Sign in with Apple, Apple In-App Purchase, cloud storage, speech recognition, AI processing, notifications, analytics, and other third-party services.
  2. When using a third-party service, you must also comply with its applicable terms. A third party is responsible for services it independently provides.
  3. We will select and manage necessary service providers as required by law and contractually restrict their processing. Details are provided in the Privacy Policy.
  4. The App may link to third-party websites or services. Review their terms and privacy practices before access.

13. Intellectual Property

  1. The App and its software, interface, icons, trademarks, text, algorithms, designs, and related materials are owned by us or our licensors.
  2. You may not use our names, trademarks, or branding without written permission in a way that suggests affiliation, endorsement, or partnership.
  3. We may use voluntarily submitted feedback to improve the Services. Feedback does not transfer ownership of your recordings or private content to us.
  4. If you believe content in the Services infringes your intellectual-property rights, email supporting evidence, the content location, and your contact information to the support email. We will respond under applicable law.

14. Prohibited Conduct

You must not use the Services to:

  1. violate a law, court order, regulatory requirement, or another person’s rights;
  2. create, store, or distribute unlawful, infringing, fraudulent, hateful, harassing, violent, unlawfully sexually explicit, sexually exploitative, or child-endangering material;
  3. transmit viruses or malicious code, or compromise service security;
  4. impersonate another person, falsify origin, or access another person’s account or data without authorization;
  5. evade payment, allowances, geographic, permission, or security controls; or
  6. engage in abusive activity beyond normal personal use that adversely affects others.

15. Changes, Updates, and Interruptions

  1. We may update the Services for security, compliance, performance, compatibility, or product improvement.
  2. If a change materially disadvantages your rights or paid Services, we will provide advance notice and, where applicable, cancellation, refund, or other remedies.
  3. The Services may be temporarily unavailable because of maintenance, network conditions, device storage, third-party outages, force majeure, or security incidents. We will take reasonable steps to minimize impact.
  4. You should install necessary updates and maintain appropriate backups of important content. This clause does not exclude liability arising from our unlawful conduct or fault where liability cannot be excluded.

16. Suspension, Termination, and Account Deletion

  1. You may stop using the Services, delete content, or request account deletion through the in-App process.
  2. When an individual recording is ordinarily deleted, it enters Recently Deleted for 30 days. During that period, the user may restore or permanently delete it; after the period expires, it is automatically permanently deleted. Account deletion is not subject to this 30-day recovery period and may remove recordings, transcripts, summaries, folders, and benefit-linkage records as disclosed on the deletion screen. The deletion screen and Privacy Policy describe scope, verification, and timing.
  3. Export content you wish to retain before deletion. Data required for legal compliance, disputes, refunds, transaction records, or security incidents may be retained for a limited period.
  4. Deleting an account does not cancel an Apple subscription. Cancel separately in your Apple ID subscription settings. Account deletion removes the App’s account and benefit linkage but does not alter a valid transaction retained by Apple. If the subscription remains active, you may later use “Restore Purchases” to link the verifiable remaining subscription benefit to a new anonymous identity or account. Content deleted with the former account will not be restored.
  5. If you materially breach these Terms, threaten service security, or if law requires action, we may restrict or terminate the Services and provide reasons and an appeal channel where required.
  6. Provisions that by their nature should survive termination, including intellectual-property, liability, and dispute provisions, will survive.

17. Warranties, Consumer Rights, and Limitation of Liability

  1. We will provide the Services with reasonable skill and care and comply with applicable consumer-protection and digital-service laws.
  2. To the extent permitted by law, the Services are provided “as is” and “as available.” We do not guarantee uninterrupted or error-free operation or completely accurate AI output.
  3. No disclaimer or limitation applies to:
    • fraud, willful misconduct, or gross negligence;
    • death, personal injury, or product liability that cannot lawfully be limited;
    • liability for violations of privacy, consumer, or other statutory rights that cannot lawfully be excluded; or
    • any other liability that applicable law does not permit us to exclude or limit.
  4. To the extent permitted by law, we are responsible for direct and reasonably foreseeable loss caused by our breach. We are not responsible for loss not caused by our breach, not reasonably foreseeable when the contract was made, or caused by unlawful recording or failure to maintain a backup.
  5. These Terms do not limit mandatory warranties or remedies available to consumers in the European Union, United Kingdom, Australia, Canada, any U.S. state, or another jurisdiction.

18. Indemnity

To the extent permitted by applicable law, if your intentional or negligent failure to obtain recording consent, infringement of third-party rights, or unlawful use causes a third party to bring a claim against us, you are responsible for reasonable and substantiated losses arising from that claim. We will provide prompt notice and permit your reasonable participation in the defense where lawful. This clause does not impose liability on a consumer where applicable law prohibits it.

19. Governing Law and Disputes

  1. Before filing a claim, we encourage you to contact kilovoice@top-stack.com. We will make reasonable efforts to resolve the dispute.
  2. For users in Mainland China, these Terms are generally governed by the laws of Mainland China. Disputes will be heard by a court with lawful jurisdiction. This does not deprive a consumer of the right to sue in the consumer’s place of residence or another court where applicable law permits.
  3. For users outside Mainland China, these Terms are governed by the law of the Operator’s place of incorporation, without depriving you of mandatory consumer-protection, data-protection, choice-of-law, or jurisdiction rights in your habitual residence.
  4. Consumers in the European Union, European Economic Area, and United Kingdom may rely on mandatory law where they reside and bring proceedings in a locally competent court.
  5. Users in the United States retain applicable federal and state rights. This draft does not require binding arbitration or waive class-action rights. Any future addition of such provisions must receive conspicuous notice and region-specific legal review.

20. Changes to These Terms

  1. We may update these Terms to reflect changes in law, regulation, Services, or our business model.
  2. We will provide advance notice of material changes by in-App notice, pop-up, email, or another reasonable method, and obtain renewed consent where required.
  3. A change will not retroactively reduce accrued rights. If you do not agree to a material change, you may stop using the Services, cancel your subscription, or delete your account as permitted by law.
  4. The current last-updated and effective dates will appear at the top.

21. Apple Platform Supplemental Terms

If you obtain the App through the Apple App Store:

  1. These Terms are concluded between you and the Operator only, not with Apple. The Operator, not Apple, is solely responsible for the App and its content.
  2. Your license is limited to a non-transferable license to use the App on Apple-branded products you own or control as permitted by the Usage Rules in the Apple Media Services Terms, except for access allowed through Family Sharing or volume purchasing.
  3. Apple has no obligation to furnish maintenance or support services for the App. The Operator is responsible for maintenance and support required by law and these Terms.
  4. If the App fails to conform to an applicable warranty, you may notify Apple, and Apple will refund the applicable purchase price for the App, if any. To the maximum extent permitted by law, Apple has no other warranty obligation. The Operator is responsible for other claims, losses, or liabilities attributable to a failure to conform to warranty.
  5. The Operator, not Apple, is responsible for product-liability, legal or regulatory compliance, consumer-protection, privacy, and other claims relating to the App or your use of it.
  6. If a third party claims that the App or your possession and use of it infringes intellectual-property rights, the Operator, not Apple, is responsible for investigating, defending, settling, and discharging the claim.
  7. You represent and warrant that you are not located in a country or region subject to a U.S. Government embargo or designated by the U.S. Government as a “terrorist supporting” country or region, and that you are not listed on a U.S. Government prohibited or restricted-party list.
  8. You must comply with applicable third-party terms when using the App, including wireless-data and network-service agreements.
  9. Apple and its subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance, Apple has the right to enforce the relevant terms against you as a third-party beneficiary.
  10. If this section conflicts with Apple’s then-current minimum EULA terms, Apple’s minimum terms control to the extent required, without reducing your non-waivable statutory rights.

22. General

  1. Headings are for convenience and do not affect interpretation.
  2. If a provision is held invalid or unenforceable, the remaining provisions remain effective, and the invalid provision will be interpreted as closely as legally possible to its intended lawful purpose.
  3. A failure to enforce a right immediately is not a waiver.
  4. We will not assign these Terms in a manner that materially reduces your rights without consent. A successor following a merger, reorganization, or business transfer must continue to honor these Terms and applicable law.
  5. The Simplified Chinese and English versions are provided for users in different regions. If they differ, they will be interpreted under mandatory law applicable where the user resides and in the manner that best reflects the parties’ actual intent. A language clause will not waive statutory consumer rights.
