TERMS OF
SERVICE

Arcticlyn is a mobile application that provides real-time aurora borealis forecasts using data from public scientific sources including NOAA SWPC, NOAA OVATION, and Open-Meteo. The app is available for iOS and, in the future, Android.

In addition to the consumer app, Arcticlyn offers a For Hotels plan that enables accommodation providers to send critical aurora alerts to their guests.

By accessing or using the Arcticlyn app or website, you confirm that you are at least 13 years of age and that you agree to be bound by these Terms of Service and our Privacy Policy.

If you do not agree to these terms, please do not use the app or website.

Aurora forecasting is an inexact science. Arcticlyn aggregates data from scientific sources and applies a scoring system to estimate aurora visibility — but auroras are natural phenomena subject to rapid, unpredictable change.

Data from NOAA SWPC, NOAA OVATION, and Open-Meteo is provided by those organizations under their own terms. Arcticlyn has no control over the accuracy, availability, or timeliness of third-party data.

You agree to use Arcticlyn only for its intended purpose. You may not:

• Reverse engineer, decompile, or attempt to extract the source code of the app
• Use the app for any unlawful purpose or in violation of any applicable laws
• Attempt to gain unauthorized access to any part of the service or its infrastructure
• Scrape, harvest, or systematically extract data from the app or its APIs
• Resell or sublicense access to the service without prior written permission

The For Hotels subscription plan is a paid B2B service subject to the following conditions:

• Subscription — billed monthly at the rate displayed at sign-up. Prices may change with 30 days' written notice.
• Free trial — a 14-day free trial is offered to new hotel accounts. No charge during the trial period. Cancellation before the trial ends incurs no cost.
• Cancellation — you may cancel at any time. Access continues until the end of the current billing period. No refunds are issued for partial billing periods.
• Alert responsibility — the hotel operator is solely responsible for the accuracy and timing of manual alerts sent through the platform. Arcticlyn is not liable for alerts sent in error.
• Guest data — hotels may not use device push notification tokens or alert data for any purpose other than aurora alerts within the Arcticlyn platform.

All content, design, code, and branding within the Arcticlyn app and website — including the name, logo, user interface, and scoring system — are the exclusive property of Arcticlyn and protected by applicable intellectual property laws.

Nothing in these Terms grants you any right to use Arcticlyn's trademarks, logos, or brand assets without prior written permission.

To the fullest extent permitted by law, Arcticlyn is provided "as is" and "as available" without any warranty of any kind, express or implied. We do not warrant that the app will be available at all times, error-free, or that forecast data will be accurate.

In no event shall Arcticlyn be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the app, including but not limited to any decisions made based on aurora forecasts provided by the service.

These Terms of Service are governed by the laws of Iceland. Any disputes arising under these terms shall be subject to the exclusive jurisdiction of the courts of Iceland.

We reserve the right to modify these Terms of Service at any time. We will notify users of material changes by updating the "Last updated" date at the top of this page. Continued use of the app after changes constitute acceptance of the new terms.
