Terms of Service

About These Terms

These Terms of Service ("Terms") govern your use of the Digamo mobile application (the "App") operated by Lost Arrow Studios, LLC ("Company," "we," "us," or "our"), a New Hampshire limited liability company. These Terms also serve as the End User License Agreement (EULA) required by the Apple App Store.

Digamo does not require creation of a standalone Digamo account. By downloading, installing, or using the App, you agree to these Terms and our Privacy Policy, which is incorporated herein by reference. We may update these Terms from time to time. Material changes will be communicated via in-app notification. Your continued use after changes take effect constitutes acceptance.

Eligibility

You must be at least 17 years old to use the App. By downloading or using the App, you represent that you meet this age requirement. The App is not intended for individuals under the age of 17.

License to Use

3.1 — Grant

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple-branded devices that you own or control, solely for your personal, non-commercial language learning purposes. This license includes use under Apple's Family Sharing feature as permitted by Apple's Usage Rules.

3.2 — Restrictions

You may not:

• Copy, modify, distribute, sell, or sublicense the App or any part of it
• Reverse engineer, decompile, or disassemble the App or the AI model files included with it
• Attempt to extract, copy, or redistribute the AI model (Qwen3) or voice files (Kokoro or Piper) bundled with the App
• Use the App to build or improve competing AI systems, datasets, or models
• Use the App for benchmarking, model extraction, automated dataset generation, or competitive analysis at scale
• Use the App for any commercial purpose without our prior written consent
• Use automated tools, bots, or scripts to interact with the App
• Use the App in any way that violates applicable law

3.3 — AI Model and Voice Files

The App includes third-party AI model and voice files licensed under their respective open-source licenses. Qwen3 is developed by Alibaba Cloud and is subject to the Qwen License Agreement. Kokoro voice models are subject to the Apache 2.0 license. Piper voice models (used for Swedish) are subject to their respective open-source licenses. Your use of these components through the App is subject to those licenses in addition to these Terms.

Subscriptions and Billing

4.1 — Subscription Plans

Digamo requires a paid subscription for full access. Current pricing is displayed in the App and in the App Store listing. We reserve the right to change pricing with reasonable advance notice.

4.2 — Billing Through Apple

All subscriptions are purchased and managed through the Apple App Store. Billing, payment processing, refunds, and subscription management are governed by Apple's terms and handled entirely by Apple. We do not receive, store, or process your payment information.

To cancel your subscription, use the standard Apple subscription cancellation process in your iPhone Settings → Apple Account → Subscriptions. Cancellation takes effect at the end of the current billing period.

4.3 — Free Trial

We may offer free trial periods at our discretion. Trial eligibility is determined by Apple and is generally limited to users who have not previously subscribed. Your subscription will automatically convert to a paid subscription at the end of the trial unless cancelled beforehand.

4.4 — Refunds

Refund requests are handled by Apple in accordance with their refund policy. To request a refund, use Apple's standard process at reportaproblem.apple.com.

4.5 — Family Sharing

Digamo supports Apple's Family Sharing feature. A single subscription may be shared with family members as permitted by Apple's Family Sharing terms. Each family member's use of the App is subject to these Terms.

4.6 — Lifetime Access

We may offer a one-time lifetime access purchase at our discretion. A lifetime access purchase grants you a non-transferable license to use the App for the commercially reasonable operational lifetime of the App, subject to these Terms.

Lifetime access includes all App updates released during the App's active operational lifetime. It does not guarantee that the App will remain available indefinitely. We reserve the right to discontinue the App at any time in accordance with Section 12 of these Terms. In the event of discontinuation, lifetime access purchasers will receive reasonable advance notice. Except where required by applicable law, lifetime access purchases are non-refundable, as the App will have been provided and available for use during the period of availability.

Lifetime access is for a single Apple ID and does not include Family Sharing unless explicitly stated at the time of purchase. Lifetime access purchases are processed through the Apple App Store and are subject to Apple's standard in-app purchase terms. As with all App Store purchases, refund requests are handled by Apple.

Acceptable Use

5.1 — Permitted Use

The App is for your personal, non-commercial language learning use. You may use it to practice conversation, build vocabulary, and improve your language skills in the supported languages.

5.2 — Prohibited Conduct

You agree not to:

• Attempt to circumvent, disable, or interfere with the App's security or functionality
• Attempt to reverse engineer, extract, or redistribute the AI model or voice files
• Attempt to manipulate the AI language partner through prompt injection, jailbreaking, or other techniques designed to cause it to operate outside its intended purpose
• Use the App to generate, distribute, or transmit content that is unlawful, harmful, or otherwise objectionable
• Resell or sublicense access to the App or its features
• Use the App in any way that violates applicable laws or regulations
• Use the App to seek or rely on medical, legal, financial, immigration, therapeutic, or other professional advice — the App is not a substitute for qualified professional consultation

5.3 — AI Limitations

The App provides AI-generated language practice for conversational use only. The AI language partner:

• Is not a licensed teacher, certified language instructor, or professional translator
• May make errors, produce unnatural phrasing, or provide inaccurate information
• May occasionally generate responses that are inaccurate, incomplete, biased, or offensive — this is an inherent characteristic of AI language models
• Runs on your device and generates responses based on the on-device model; quality may vary by device and language
• Should not be relied upon as the sole source of language instruction for high-stakes purposes
• Is not intended to provide medical, legal, financial, immigration, therapeutic, or other professional advice

We make no representation that use of the App will result in any particular level of language proficiency.

Intellectual Property

6.1 — Our Property

The App, excluding the third-party AI model and voice files, is owned by Lost Arrow Studios, LLC and protected by applicable intellectual property laws. These Terms do not grant you any ownership rights in the App.

6.2 — Third-Party Components

The App incorporates third-party open-source components including Qwen3 (AI language model, Alibaba Cloud), Kokoro (text-to-speech voice models, Apache 2.0), and Piper (text-to-speech voice models for Swedish). These components are subject to their respective open-source licenses. Nothing in these Terms grants you rights beyond those provided by the applicable open-source licenses.

6.3 — Feedback

If you submit feedback or suggestions about the App, you grant us a perpetual, irrevocable, royalty-free license to use that feedback for any purpose without compensation or attribution.

User Content and AI Output

7.1 — Ownership

You retain ownership of the content you provide through the App, including your spoken and typed inputs. Subject to your compliance with these Terms, you may use AI-generated responses created by the App for personal, non-commercial purposes.

7.2 — No Remote Training

We do not use your on-device conversations to train remote AI models. Because all conversation processing occurs locally on your device and is never transmitted to our servers, your interactions with the App are not accessible to us and cannot be used for any training purpose.

7.3 — On-Device Storage

Conversation history and your learner profile are stored locally on your device only. You may clear this data at any time via Settings → Danger Zone, or by deleting the App.

Privacy

Your use of the App is subject to our Privacy Policy, available within the App under Settings → Legal → Privacy Policy. The Privacy Policy is incorporated into these Terms by reference.

Digamo is designed so that conversation content and voice interactions are processed locally on your device and are not transmitted to our servers. See the Privacy Policy for full details on all data practices, including CDN downloads and Apple subscription validation.

Disclaimers

The App relies on AI models that may produce errors, inconsistencies, or inaccurate language guidance. We make no guarantees regarding language learning outcomes. Results depend on many factors outside our control, including user effort and consistency of practice.

The App requires compatible Apple hardware running a supported version of iOS. Current minimum requirements are listed in the App Store. Performance may vary by device. We make no warranty regarding the App's performance on any specific device configuration.

Limitation of Liability

Indemnification

You agree to indemnify and hold harmless Lost Arrow Studios, LLC and its members, officers, and agents from any claims, liabilities, damages, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of the App; (b) your violation of these Terms; or (c) your violation of any applicable law or third-party rights.

Dispute Resolution

12.1 — Informal Resolution

Before initiating any formal dispute, please contact us at support@digamo.ai and attempt to resolve the matter informally. We will use good-faith efforts to resolve issues within 30 days.

12.2 — Governing Law

These Terms are governed by the laws of the State of New Hampshire, without regard to conflict of laws principles.

Changes to the App

We may update, modify, or discontinue the App or any feature at any time. We may change, update, replace, or discontinue the AI models or voice systems used by the App at any time, including changes that may affect voice quality, language support, or conversational behavior. App updates may include improved AI models or voice files, which will be downloaded to your device when available. We will provide reasonable notice of material changes that affect paid subscribers.

Termination

These Terms remain in effect until terminated. You may terminate by deleting the App and cancelling your subscription. We may suspend or terminate your access to the App for violations of these Terms, including attempts to circumvent security protections, misuse subscription systems, reverse engineer AI model files, or engage in other prohibited uses described in these Terms. Sections 6, 7, 9, 10, 11, 12, and 15 survive termination.

Intellectual Property Complaints

If you believe the App or its content infringes your intellectual property rights, please contact us at support@digamo.ai.
