Terms of Use — Lumos: Sun and Moon Tracker
These Terms of Use ("Terms") govern your use of the Lumos: Sun and Moon Tracker mobile application (the "App"), published by Luminous Labs LLC ("Luminous Labs," "we," "us"). By downloading or using the App you agree to these Terms. If you do not agree, do not use the App.
On iOS, your download and license of the App are also governed by Apple's standard Licensed Application End User License Agreement; these Terms supplement that agreement. On Android, your download is governed by the Google Play Terms of Service; these Terms supplement those.
Subscriptions and purchases
Some App features require a paid upgrade, available either as an auto-renewing subscription or as a one-time lifetime purchase. All subscriptions and purchases are processed by Apple (through the App Store) or Google (through Google Play) — never by Luminous Labs directly. Luminous Labs does not collect or store payment information and cannot charge you directly.
Subscriptions renew automatically at the end of each billing period unless cancelled. You can cancel at any time in your device's subscription settings (App Store or Google Play subscription management); cancelling stops future renewals but does not refund the current period. Deleting the App does not cancel a subscription. The lifetime purchase is a one-time transaction and does not renew or recur.
Free trials, introductory offers, and their terms are presented before purchase and are managed by the same platform billing systems. We may modify or discontinue trial offers for future subscribers at any time; this does not affect a trial already in progress.
Subscription prices may change. Price changes take effect according to the rules of the platform you purchased through, which may require advance notice to you or your explicit consent before a renewal at the new price.
Refunds
Refunds are governed by the policies of the platform you purchased through. Refund requests for App Store purchases are made to Apple and decided by Apple; Luminous Labs cannot issue App Store refunds. For Google Play purchases, refund requests are handled through Google Play. Except where the platform's policies or applicable law provide otherwise, purchases (including subscription fees and the lifetime purchase) are non-refundable.
No accounts
The App does not offer or require user accounts. Nothing in these Terms requires you to register or maintain credentials with Luminous Labs.
Accuracy of information — please read
The App computes astronomical estimates — including positions and paths of the sun and moon, rise and set times, and shadow projections — using standard algorithms and the location, date, and time you provide. These results are estimates provided for general informational and planning purposes only. Real-world conditions (terrain, obstructions, atmospheric refraction, device sensor accuracy, and map or imagery inaccuracies) can cause meaningful differences between the App's output and what you observe.
The App is not designed or offered for use in navigation, surveying, property or boundary determinations, legal or regulatory compliance, or any safety-critical application, and you must not rely on it for such purposes. Decisions you make based on the App's output — including photography plans, gardening, construction, and real-estate decisions — are your own responsibility.
Intellectual property
The App and its content, features, and functionality are the exclusive property of Luminous Labs LLC and its licensors and are protected by copyright, trademark, and other laws. The Lumos name and logo may not be used without prior written consent from Luminous Labs. Map data and imagery are provided by Apple and Google and remain subject to their terms.
Beta versions
We may make pre-release ("beta") versions of the App available to a limited group of testers. Beta versions are provided as-is for testing purposes; they may contain errors, may change or lose functionality without notice, and may stop working at the end of a test period. If you provide feedback on a beta version, you grant Luminous Labs the right to use that feedback without restriction or compensation.
Third-party services
The App relies on third-party services (including Apple and Google mapping services) and may contain links to third-party websites. Luminous Labs does not control and is not responsible for third-party services or content. Your use of those services is subject to their own terms and privacy policies. How the App handles your data, including data processed by third-party services, is described in our Privacy Policy.
The App includes Google Maps features and content, including Google Maps, Street View, and place search. Use of Google Maps features and content is subject to the then-current versions of the Google Maps/Google Earth Additional Terms of Service and the Google Privacy Policy.
Disclaimer of warranties
The App is provided "AS IS" and "AS AVAILABLE," without warranties of any kind, express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. Luminous Labs does not warrant that the App will be uninterrupted, error-free, or secure, or that defects will be corrected.
Limitation of liability
To the maximum extent permitted by law, Luminous Labs LLC and its licensors shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, or goodwill, arising from your use of or inability to use the App, under any legal theory, even if advised of the possibility of such damages. To the maximum extent permitted by law, Luminous Labs' total liability for all claims relating to the App is limited to the amount you paid for the App in the twelve (12) months before the claim arose, or fifty U.S. dollars ($50), whichever is greater.
Termination
You may stop using the App at any time. We may suspend or discontinue the App or any feature at any time. Sections that by their nature should survive (including Accuracy of information, Intellectual property, Disclaimer of warranties, and Limitation of liability) survive any termination.
Governing law
These Terms are governed by the laws of the State of North Carolina, United States, without regard to conflict-of-law provisions. Failure to enforce any provision is not a waiver. If any provision is held unenforceable, the remaining provisions remain in effect.
Changes to these Terms
We may update these Terms from time to time. The current version, with its effective date, is posted at this address. For material changes we will provide notice in advance where reasonably possible (for example, in the App's release notes). Continued use of the App after changes take effect constitutes acceptance of the updated Terms.
