Terms & Conditions

Last updated: June 18, 2026
Effective date: June 18, 2026

These Terms of Service and End User License Agreement (the "Terms") are a binding agreement between you and Bounty Studio, Inc. ("Bounty Studio", "we", "us", or "our") governing your use of the Line mobile application and related services (together, the "App"). Please read them carefully.

By downloading, installing, or using the App, you agree to these Terms and to our Privacy Policy. If you do not agree, do not download, install, or use the App.

  1. The App

Line is a language-learning app. It lets you have real-time, out-loud voice conversations with AI characters inside story scenarios on an explorable map, create your own scenarios and characters, and receive learning features such as translations, romanization, pronunciation playback, suggested responses, and grammar reports. The App relies on third-party artificial intelligence services to generate conversations, artwork, and audio, as described in our Privacy Policy.

  1. Eligibility and accounts

• Age. You must be at least 13 years old to use the App. If you are under 18, you may use the App only with the consent and supervision of a parent or legal guardian who agrees to these Terms. Where local law sets a higher minimum age, that age applies.
• Account. You may need to create an account using an email and password, Sign in with Apple, or Sign in with Google. You agree to provide accurate information and to keep it up to date.
• Account security. You are responsible for keeping your credentials confidential and for all activity that occurs under your account. Notify us promptly of any unauthorized use.

  1. License

Subject to your compliance with these Terms, Bounty Studio grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use one copy of the App on any Apple-branded device that you own or control, as permitted by the Usage Rules set out in the Apple Media Services Terms and Conditions. This license is the "Licensed Application" license described in Section 13 (Apple App Store terms).

  1. Restrictions

You agree that you will not, and will not permit anyone else to:

• Copy, modify, adapt, translate, or create derivative works of the App, except as permitted by law.
• Reverse engineer, decompile, or disassemble the App, or attempt to derive its source code, except to the extent that this restriction is prohibited by applicable law.
• Rent, lease, lend, sell, sublicense, distribute, or otherwise transfer the App to a third party.
• Remove, alter, or obscure any proprietary notices in the App.
• Access the App to build a competing product or service.
• Use any automated means to access the App, or interfere with or disrupt the App or its servers, including by exceeding rate limits, scraping, or attempting to gain unauthorized access.
• Use the App in any way that violates applicable law or these Terms.

  1. Your content and content you create

• Your content. "Your Content" means the scenarios, characters, settings, prompts, voice input, messages, and other content you create, submit, or generate through the App.
• Ownership and license to us. As between you and Bounty Studio, you retain whatever rights you have in Your Content. You grant Bounty Studio a worldwide, non-exclusive, royalty-free license to host, store, reproduce, modify (for example, to format or adapt it), process, and display Your Content, and to transmit it to the third-party providers described in our Privacy Policy, in each case solely to operate, provide, secure, and improve the App. This license ends when you delete Your Content or your account, except for content already shared with others, content retained in backups for a limited period, or where retention is required by law.
• Your responsibility. You are solely responsible for Your Content and represent that you have the rights necessary to submit it and that it does not violate these Terms or any law or third-party right.

  1. AI-generated content

You understand and agree that:

• Conversations, characters, artwork, audio, translations, romanizations, suggested responses, and grammar reports are generated by automated artificial intelligence systems.
• AI-generated content may be inaccurate, incomplete, offensive, or otherwise objectionable, and may not reflect real people, places, events, or correct language usage. It is provided for language-learning and entertainment purposes only and is not professional, medical, legal, financial, or other expert advice.
• You should independently verify important information and use your own judgment. Bounty Studio does not guarantee the accuracy, quality, or suitability of AI-generated content.
• Output generated for different users may be similar or identical, and we make no exclusivity promises regarding generated content.

  1. Acceptable use

You agree not to use the App, and not to create, submit, or generate content that:

• Is unlawful, infringing, defamatory, harassing, hateful, or threatening.
• Sexualizes minors or depicts child sexual abuse material in any form.
• Is sexually explicit or pornographic where prohibited, or that promotes violence or self-harm.
• Violates the intellectual property, privacy, or other rights of any person.
• Impersonates any person or misrepresents your affiliation with any person or entity.
• Attempts to bypass content safeguards or to elicit prohibited content from the AI characters.
• Contains malware, or is intended to disrupt, damage, or gain unauthorized access to any system or data.

We may, but are not obligated to, monitor, review, or remove content, and we may suspend or terminate access for conduct we reasonably believe violates these Terms or harms the App, other users, or third parties.

  1. Subscriptions, purchases, and payment

The App may offer paid subscriptions or other in-app purchases. If it does, the following applies:

• Billing through Apple. Purchases are processed by Apple through your Apple Account, not directly by Bounty Studio. Payment is charged to your Apple Account at confirmation of purchase.
• Auto-renewing subscriptions. Subscriptions automatically renew for the same period at the then-current price unless you cancel at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within 24 hours before the end of the current period.
• Managing and canceling. You can manage or cancel a subscription, and turn off auto-renewal, in your Apple Account settings on your device. Deleting the App does not cancel a subscription.
• Free trials. Any unused portion of a free trial is forfeited when you purchase a subscription, where applicable.
• Refunds. Purchases are handled by Apple and are subject to Apple's refund policies. Except where required by law, payments are non-refundable, and Bounty Studio does not control and cannot issue refunds for App Store purchases.
• Price changes. We may change prices and subscription features. Where required, we will give you advance notice and, where required, the opportunity to cancel before the change takes effect.

  1. Intellectual property

The App, including its software, design, text, graphics, logos, the "Line" name, audio, and all related intellectual property (excluding Your Content), is owned by Bounty Studio or its licensors and is protected by intellectual-property laws. Except for the license granted in Section 3, these Terms do not grant you any right, title, or interest in the App.

  1. Feedback

If you send us suggestions, ideas, or other feedback about the App, you grant Bounty Studio a perpetual, irrevocable, worldwide, royalty-free license to use that feedback for any purpose without obligation or compensation to you.

  1. Third-party services

The App relies on third-party services, including the AI and infrastructure providers listed in our Privacy Policy. Your use of the App may be subject to those third parties' terms, and you agree to comply with any applicable third-party terms. Bounty Studio is not responsible for third-party services and does not endorse them.

  1. Disclaimers, limitation of liability, and indemnification

12.1 Disclaimer of warranties

To the maximum extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, whether express, implied, or statutory, including any implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the App will be uninterrupted, secure, error-free, or that any content, including AI-generated content, will be accurate or reliable. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

12.2 Limitation of liability

To the maximum extent permitted by law, Bounty Studio and its officers, employees, and agents will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of profits, data, goodwill, or other intangible losses, arising out of or relating to your use of, or inability to use, the App. To the maximum extent permitted by law, Bounty Studio's total liability for all claims relating to the App will not exceed the greater of the amount you paid us for the App in the 12 months before the event giving rise to the claim, or twenty-five U.S. dollars (25 USD). Some jurisdictions do not allow certain limitations of liability, so some of these limitations may not apply to you.

12.3 Indemnification

You agree to indemnify and hold harmless Bounty Studio and its officers, employees, and agents from any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of or related to Your Content, your use of the App, or your violation of these Terms or any law or third-party right.

  1. Apple App Store terms

This Section applies because you obtained the App from the Apple App Store. You and Bounty Studio acknowledge that:

  1. Acknowledgement. These Terms are between you and Bounty Studio only, and not with Apple Inc. ("Apple"). Bounty Studio, not Apple, is solely responsible for the App and its content.

  2. Scope of license. The license granted to you for the App is limited to a non-transferable license to use the App on any Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be accessed and used by other accounts associated with you via Family Sharing or volume purchasing.

  3. Maintenance and support. Bounty Studio is solely responsible for providing any maintenance and support services for the App. Apple has no obligation to furnish any maintenance and support services for the App.

  4. Warranty. Bounty Studio is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the App fails 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 law, Apple has no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs, or expenses attributable to any failure to conform to any warranty are the sole responsibility of Bounty Studio.

  5. Product claims. Bounty Studio, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession or use of the App, including (a) product liability claims, (b) any claim that the App fails to conform to any applicable legal or regulatory requirement, and (c) claims arising under consumer protection, privacy, or similar legislation, including in connection with the App's use of any third-party software or services.

  6. Intellectual property rights. In the event of any third-party claim that the App or your possession and use of the App infringes that third party's intellectual property rights, Bounty Studio, not Apple, will be solely responsible for the investigation, defense, settlement, and discharge of any such claim.

  7. Legal compliance. You represent and warrant that (a) you are not located in a country that is subject to a U.S. Government embargo or that has been designated by the U.S. Government as a "terrorist supporting" country, and (b) you are not listed on any U.S. Government list of prohibited or restricted parties.

  8. Developer name and address. Questions, complaints, or claims about the App should be directed to: Bounty Studio, Inc., [Bounty Studio, Inc. mailing address], [support@bounty.app].

  9. Third-party terms of agreement. You must comply with applicable third-party terms of agreement when using the App.

  10. Third-party beneficiary. You and Bounty Studio acknowledge and agree that Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms, and that, upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary of these Terms.

  11. Termination

These Terms remain in effect until terminated. You may stop using the App and delete your account at any time. We may suspend or terminate your access to the App at any time, with or without notice, if we reasonably believe you have violated these Terms or to protect the App or others. Upon termination, the license in Section 3 ends and you must stop using the App. Sections that by their nature should survive termination will survive, including Sections 5, 6, 9, 10, 12, 13, 15, and 16.

  1. Governing law and dispute resolution

These Terms are governed by the laws of the State of [State], without regard to its conflict-of-laws rules, except that the Federal Arbitration Act governs the interpretation and enforcement of the arbitration provisions below. This governing-law choice does not deprive you of the protection of mandatory consumer-protection laws of the country where you live.

Please read this section carefully. It affects how disputes are resolved.

• Informal resolution first. Before bringing a formal claim, you agree to contact us at support@bounty.app and try to resolve the dispute informally for at least 30 days.
• Binding arbitration. If we cannot resolve a dispute informally, you and Bounty Studio agree to resolve any dispute arising out of or relating to these Terms or the App through final and binding arbitration on an individual basis, administered by [JAMS or AAA] under its applicable rules, rather than in court, except as provided below.
• Class-action waiver. You and Bounty Studio agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class or representative proceeding.
• Exceptions. Either party may bring a claim in small-claims court, and either party may seek injunctive relief in court for intellectual-property infringement or unauthorized access to the App.

If any part of this Section is found unenforceable, the remainder will continue to apply, except that if the class-action waiver is found unenforceable, this entire arbitration Section will not apply.

  1. General

• Changes to these Terms. We may update these Terms from time to time. When we make material changes, we will update the "Last updated" date and, where appropriate, provide notice in the App. Your continued use of the App after the changes take effect means you accept the revised Terms.
• Entire agreement. These Terms and the Privacy Policy are the entire agreement between you and Bounty Studio regarding the App and supersede any prior agreements.
• Severability. If any provision is found unenforceable, the remaining provisions remain in full effect.
• No waiver. Our failure to enforce any provision is not a waiver of our right to do so later.
• Assignment. You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, or sale of assets.
• Contact. Questions about these Terms can be sent to support@bounty.app
