Terms of Use

Last Updated: 12 December 2025

These Terms of Use govern your access to and use of the Lumnea mobile application (the “App”), operated by Instance Design (“we,” “our,” or “us”). By downloading, accessing, or using the App, you agree to these Terms. If you do not agree, you should not use the App.

  1. About Lumnea

Lumnea is a mobile application that allows users to generate flashcards and audio content using artificial intelligence, track progress such as streaks, and save content for later use. The App offers both free features and optional paid subscriptions. We may update or change features over time.

  1. Accounts and Access

Some features of the App require an account, which is created using Apple Sign-In or Google Sign-In. You are responsible for maintaining the security of your account and for all activity that occurs under it. You agree not to share access to your account or create multiple accounts to bypass usage limits or restrictions.

We reserve the right to suspend or terminate accounts that violate these Terms or misuse the App.

  1. Subscriptions and Payments

Lumnea offers optional paid subscriptions that unlock additional features. All subscription payments are processed by Apple through Apple StoreKit. We do not collect or store payment card details.


Subscriptions renew automatically unless cancelled before the renewal processing period begins, which typically occurs up to 24 hours before the renewal date. You may cancel your subscription at any time through your Apple ID settings. Cancellation takes effect at the end of the current billing period, and you will continue to have access until that time. Refunds are handled solely by Apple in accordance with App Store policies.

  1. Acceptable Use

You agree to use Lumnea only for lawful purposes and in a manner that does not harm the App, its systems, or other users. You must not attempt to interfere with the App’s operation, reverse engineer or modify the App, use automated tools to access the service, or attempt to bypass limits, safeguards, or subscription controls.


You must not use the App to generate or distribute content that is illegal, abusive, or infringes the rights of others.

  1. Abuse, Misuse, and Account Restrictions

To protect the stability and integrity of Lumnea, we monitor for abnormal or abusive usage. This includes excessive automated requests, attempts to overload systems, unauthorised scraping or automation, denial-of-service activity, or efforts to exploit pricing or billing mechanisms.


If such activity is detected, we may apply restrictions, rate limits, temporary suspensions, or permanent account termination without prior notice. These actions are taken at our discretion to protect the App and other users.

  1. AI-Generated Content

Lumnea uses artificial intelligence to generate content. We do not guarantee that AI-generated content is accurate, complete, or suitable for any specific purpose. You are responsible for reviewing and verifying content before relying on it. Use of AI-generated content is at your own risk.

  1. Intellectual Property

The App, its design, functionality, and underlying software are owned by Instance Design and protected by applicable intellectual property laws. You may not copy, modify, distribute, or create derivative works from the App without permission.


Any content you provide remains yours, but you grant us permission to process it solely to operate and deliver the App’s functionality.

  1. Third-Party Services

Lumnea relies on third-party services to provide essential functionality such as authentication, analytics, AI processing, and subscription management. Your use of the App may be subject to the terms and policies of those providers. We are not responsible for the actions or availability of third-party services.

  1. Availability and Changes

We aim to keep Lumnea available and functioning reliably, but we do not guarantee uninterrupted or error-free operation. We may modify, suspend, or discontinue parts of the App at any time, with or without notice.

  1. Limitation of Liability

To the fullest extent permitted by law, Instance Design will not be liable for indirect, incidental, or consequential damages arising from your use of the App, including loss of data or loss of access. Our total liability will not exceed the amount you paid for the App in the 12 months preceding the claim.

11. Governing Law

These Terms are governed by the laws of Malaysia. Any disputes should first be raised with us directly in an attempt to resolve them informally.

12. Changes to These Terms

We may update these Terms from time to time. Updates take effect when posted. Continued use of the App after changes are made constitutes acceptance of the updated Terms.
