Terms of Service

These Terms of Service ("Terms") govern your access to and use of Dylen (the "Service"), including our websites, applications, APIs, and related services (collectively, the "Services"). By accessing or using the Services, you agree to these Terms. If you do not agree, do not use the Services.

If you are using the Services on behalf of a company, organisation, or other entity ("Organisation"), you represent and warrant that you have authority to bind that Organisation, and "you" includes the Organisation.

1. Who We Are

The Services are provided by Dylen (the "Company," "we," "us," or "our").

Contact: support@dylen.app

2. Definitions

• "Dylen" means the Services offered under the Dylen brand.
• "Customer Content" means any content you submit to the Services, including prompts, text, files, and structured data.
• "Output(s)" means any content, data, or results generated or returned by the Services in response to Customer Content, including structured lesson and exercise content.
• "Sharing Link" means an in-app sharing mechanism that allows an Output to be viewed by others, subject to the visibility level you set.
• "Priority List" means the approval queue described under Eligibility and Accounts.
• "Services" has the meaning set out in the introduction.

3. Eligibility and Accounts

You must be at least 13 years old to use the Services. By creating an account, you represent that you meet this requirement. Users aged 13–17 are subject to additional content restrictions as described in our Privacy Policy.

Priority List and Account Approval. At launch, all new accounts may be placed on a Priority List and require approval before full access is granted. We may approve, delay, or deny access at our sole discretion, including for capacity, operational, compliance, or risk reasons.

You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us promptly at support@dylen.app if you believe your account has been compromised.

4. The Services

Dylen provides an AI-powered learning content generation service that processes your inputs to produce structured lesson and drill content. The Services may include background jobs and orchestration across multiple components, including third-party AI model providers.

We may modify, discontinue, or suspend any part of the Services at any time, including to improve performance, security, or compliance, without liability to you.

5. Acceptable Use

You agree not to, and not to assist others to:

• Use the Services for unlawful, harmful, or abusive activities.
• Submit content that infringes intellectual property, privacy, or other rights.
• Attempt to gain unauthorised access to systems or accounts, or probe, scan, or test vulnerabilities except as expressly permitted in writing.
• Interfere with or disrupt the Services, including by introducing malware, denial-of-service activity, or excessive automated requests.
• Reverse engineer, decompile, or attempt to extract source code, models, prompts, system logic, or underlying data structures from the Services, except to the extent prohibited by law.
• Circumvent rate limits, quotas, access controls, safety filters, account approval requirements, or any other technical restrictions.
• Resell, sublicense, rent, lease, or provide access to the Services or Outputs to third parties, or use the Services to build or operate a competing product or service.
• Misrepresent Outputs as being endorsed or guaranteed by Dylen.

Prohibited Topics. The following are prohibited: sexually explicit content, graphic violence, partisan political advocacy, and operational military tactics or weapons training instructions. Educational content covering these subject areas — including history, civics, military history, political science, and academic study of conflict — is permitted. We enforce these restrictions through automated checks and manual review. Attempting to bypass them violates these Terms.

Enforcement. We may enforce these restrictions through content removal, access restriction, suspension, and termination. We may apply a notice and strike system — generally a first notice, a second notice, and termination on a third violation (which may occur without further notice for serious violations). We may also block re-registration, including banning associated email addresses. We may terminate accounts immediately for egregious violations or repeated attempts to circumvent restrictions.

6. Prohibited Content

In addition to the acceptable use restrictions above, you may not use the Services to generate, store, or transmit content that:

• Is sexually explicit, pornographic, or exploitative of minors in any way.
• Glorifies, promotes, or instructs in violence, terrorism, or self-harm.
• Constitutes targeted harassment, hate speech, or discrimination on the basis of protected characteristics.
• Contains disinformation designed to deceive, manipulate, or harm others.
• Violates any applicable law or regulation in your jurisdiction or ours.

7. Your Content and Responsibilities

You represent and warrant that: (a) you have all rights and permissions needed to submit Customer Content; (b) your Customer Content does not violate law or these Terms; and (c) you will not submit sensitive personal information (e.g. medical data, financial account numbers, government identifiers, or passwords) unless a feature explicitly requires it and you have a lawful basis and required consents.

Data Handling. Files uploaded solely for a single generation request are deleted approximately 24 hours after upload. Content you save to your Source Library for indexing and reuse is retained for the duration of your active account or until you remove it. Generated lesson and drill content may persist in our systems for the duration permitted under your plan tier. We may change retention practices at our discretion, including for operational, legal, security, or compliance reasons.

Responsibility. You are responsible for Customer Content you submit and your use of Outputs. We do not have a general obligation to monitor Customer Content or Outputs, but may review and take action when content is flagged or we otherwise become aware of potential violations.

8. AI Outputs and Limitations

The Services generate content using machine learning models. You acknowledge that:

• Outputs may be incorrect, incomplete, misleading, or unsuitable for your purposes.
• You are responsible for reviewing Outputs before relying on them, including for accuracy, safety, and compliance with applicable requirements.
• The Services are not a substitute for professional advice, including legal, medical, financial, or safety advice.
• AI-generated learning content does not constitute a guarantee of educational, professional, or personal outcomes. Individual results depend on effort, engagement, and the accuracy of inputs provided.

You will not rely on the Services for high-stakes decisions without appropriate human review and safeguards in place.

9. Intellectual Property and Content Ownership

9.1 Our IP. We and our licensors retain all rights, title, and interest in and to the Services, including software, documentation, and all non-customer materials. These Terms do not grant you any right to use our trademarks, logos, or branding.

9.2 Customer Content. As between you and us, you retain your rights in Customer Content. You grant us a non-exclusive, worldwide, royalty-free licence to host, process, transmit, and display Customer Content solely to provide, maintain, and improve the Services and to comply with law.

9.3 Outputs — Ownership and Access. You provide the topic and instructions; Dylen's AI generates the resulting lesson and drill content. As between you and us, Dylen retains ownership of generated Outputs. You receive a non-exclusive, non-transferable licence to access, view, and use Outputs within the Services for personal or professional learning purposes, for the duration permitted by your plan. On higher-tier plans, extended access and retention rights may apply as described in the applicable plan terms.

9.4 Exports. Outputs may not be scraped, extracted in raw structured form (e.g. JSON), or reproduced outside the Services in a manner that replicates or competes with the Services. Where we provide an official export feature, you may use it to export a plain-text or document representation of your Outputs for personal use. Any automated or unauthorised extraction of Outputs is a material violation of these Terms.

9.5 Sharing. You may share Outputs only using the sharing features we provide within the Services. Outputs set to a public or open visibility level may be viewed by anyone with the link; other visibility levels may require the recipient to have an authenticated account. You may not sell, resell, sublicence, or otherwise exploit Outputs commercially, nor use Outputs to build or operate a competing product or service.

We do not guarantee that Outputs are unique or non-infringing of third-party rights.

10. Third-Party Services

The Services may integrate with third-party services, including authentication providers and AI model providers. Your use of those third-party services is governed by their own terms and policies. We are not responsible for third-party services or content outside our reasonable control.

11. Fees, Trials, and Taxes

If the Services include paid tiers, you agree to pay all applicable fees and taxes. Additional terms may apply to trials, discounts, renewals, and refunds, which will be presented at the time of purchase. Fees are non-refundable except as required by applicable law or as expressly stated at purchase.

12. Suspension and Termination

We may suspend or terminate your access to the Services if you violate these Terms or applicable law, to protect the security or integrity of the Services, or if required by law. You may stop using the Services at any time.

Provisions of these Terms that by their nature should survive termination — including those relating to intellectual property, disclaimers, limitation of liability, indemnification, and dispute resolution — will survive termination.

13. Disclaimers

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

We do not warrant that the Services will be uninterrupted, secure, error-free, or that Outputs will be accurate, complete, or suitable for any particular purpose. We make no representations regarding educational, professional, or personal outcomes from use of the Services. Results depend on individual effort, the accuracy of inputs, and factors outside our control.

We are not liable for any content generated by AI systems that is inaccurate, offensive, or otherwise unsuitable for your intended use.

14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

• WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
• OUR TOTAL CUMULATIVE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICES WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US FOR THE SERVICES IN THE 12 MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) US$100.

Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

15. Indemnification

You agree to indemnify, defend, and hold harmless the Company and its affiliates, officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable legal fees) arising out of or related to: (a) your Customer Content; (b) your use of the Services or any Output; (c) your violation of these Terms or applicable law; or (d) your violation of any third-party right, including intellectual property or privacy rights.

16. Force Majeure

Neither party will be liable for any failure or delay in performance under these Terms to the extent such failure or delay is caused by circumstances beyond that party's reasonable control, including acts of God, natural disasters, war, terrorism, pandemic, government action, internet or infrastructure outages, or third-party service failures. The affected party will promptly notify the other and use reasonable efforts to resume performance as soon as practicable.

17. Severability

If any provision of these Terms is found to be unenforceable or invalid under applicable law, that provision will be modified to the minimum extent necessary to make it enforceable, or if it cannot be modified, severed. The remaining provisions of these Terms will continue in full force and effect.

18. Dispute Resolution; Governing Law

These Terms and any disputes arising out of or relating to them or the Services will be subject to the governing law and jurisdiction specified in any additional terms or agreement applicable to your account. In the absence of such terms, disputes will be resolved by binding arbitration or in a court of competent jurisdiction as mutually agreed.

If you are a consumer in a jurisdiction that provides mandatory consumer rights or local court access, nothing in these Terms limits those rights.

19. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will provide notice by updating the "Last updated" date above and, where practicable, by notifying you directly. Your continued use of the Services after changes become effective constitutes acceptance of the revised Terms. If you do not agree to a material change, your remedy is to stop using the Services.
