Terms of Service

1. Operator & Acceptance of Terms

RailTrailWx (railtrailwx.com) is owned and operated by Entrain Weather, LLC, a Pennsylvania limited liability company. All rights, obligations, and liabilities under these Terms belong to Entrain Weather, LLC.

By accessing or using RailTrailWx, you agree to be bound by these Terms of Service (“Terms”). If you do not agree to any part of these Terms, you may not use the service. Your continued use of RailTrailWx after any updates to these Terms constitutes acceptance of the revised Terms.

2. Decision Support, Not Decision-Making

RailTrailWx provides decision-support information based on user-supplied comfort preferences. It is not a safety tool.

• Comfort scores reflect your stated comfort thresholds — not objective safety, weather severity, or NWS warnings.
• RailTrailWx does not make decisions for you.
• Outdoor activities have inherent dangerous risks. Trails expose participants to risks including severe weather, lightning, flash flooding, extreme heat or cold, wildlife encounters, and remote terrain with limited access to emergency services.
• You are solely responsible for all outdoor activity decisions, including in adverse or dangerous conditions.
• Custom scoring profiles can produce arbitrarily permissive results. A profile that vetoes nothing will return a score of 100 in any weather.
• Always consult official National Weather Service (NWS) forecasts and alerts, and exercise your own judgment before heading out.

BY USING RAILTRAILWX, YOU EXPRESSLY ASSUME ALL RISKS ASSOCIATED WITH OUTDOOR RECREATIONAL ACTIVITIES, INCLUDING BUT NOT LIMITED TO PERSONAL INJURY, DEATH, AND PROPERTY DAMAGE. YOU ACKNOWLEDGE THAT WEATHER CONDITIONS CAN CHANGE RAPIDLY AND THAT RAILTRAILWX COMFORT SCORES ARE DECISION-SUPPORT TOOLS ONLY — NOT SAFETY GUARANTEES. YOUR DECISION TO ENGAGE IN ANY OUTDOOR ACTIVITY IS SOLELY YOUR OWN, AND YOU VOLUNTARILY ACCEPT ALL RISKS INHERENT IN SUCH ACTIVITIES. THIS ASSUMPTION OF RISK AND WAIVER OF LIABILITY FOR NEGLIGENCE IS ENTERED INTO FREELY AND VOLUNTARILY IN CONNECTION WITH OUTDOOR RECREATIONAL ACTIVITY AND IS INTENDED TO BE ENFORCEABLE TO THE FULLEST EXTENT PERMITTED UNDER APPLICABLE LAW, INCLUDING THE LAW OF THE COMMONWEALTH OF PENNSYLVANIA.

3. Description of Service

RailTrailWx, a service of Entrain Weather, LLC, provides weather-based comfort scoring and forecast information tailored to rail-trail recreation and user-defined comfort preferences. Features include:

• Hourly trail comfort scores derived from multiple Numerical Weather Prediction (NWP) models
• Customizable activity and comfort profiles
• Interactive trail maps with weather overlays and NEXRAD radar
• NWS weather alerts for trail areas
• Route-specific scoring along trail segments
• User accounts for saved preferences and subscriptions

If enabled by you, map location display is provided for convenience only. Browser or device location may be inaccurate, delayed, or unavailable, and it is not intended for emergency use, turn-by-turn navigation, or safety-critical decisions.

4. Acceptable Use

You agree to use RailTrailWx only for lawful purposes. You may not:

• Violate any applicable federal, state, or local laws or regulations
• Circumvent or attempt to bypass access controls or subscription restrictions
• Scrape, crawl, or harvest data from the service at scale without prior written consent from Entrain Weather, LLC
• Transmit malicious code, viruses, or any software intended to damage or interfere with the service
• Submit false, misleading, or fraudulent information
• Harass, defame, or harm other users or third parties
• Spam, phish, or engage in any unauthorized commercial messaging through the platform
• Reproduce, redistribute, or commercially exploit RailTrailWx content, comfort scores, or algorithms without authorization

RailTrailWx Comfort Score graphics may be shared provided they are reproduced in their entirety without alteration, including the name of the trail, the route, the score, activity, forecast valid time, forecast generation time, www.RailTrailWx.com attribution, and the Personalized RailTrailWx Comfort Score notice of availability.

Personalized scores may be shared. When shared, they will be labeled as “Personalized Score” or “[First Name]’s Personalized Score” if a first name is set on the user’s account, rather than the user’s custom profile name. This labeling is required because personalized scores are user-specific and may not be meaningful or accurate to others. A link is provided next to the RailTrailWx Comfort Score graphic for easy sharing that exactly meets these requirements. All other reproduction or redistribution of RailTrailWx content without written permission is prohibited.

Violations may result in immediate account termination and, where applicable, legal action.
