Privacy Policy
Effective: May 20, 2026
1. Who We Are
RailTrailWx (railtrailwx.com) is owned and operated by Entrain Weather, LLC, a Pennsylvania limited liability company. This Privacy Policy explains how we collect, use, and protect your information when you use our service. By using RailTrailWx, you agree to the terms of this Privacy Policy.
2. Information We Collect
Personal data
When you create an account, we collect your email address via Clerk (our authentication provider). We store your account information — including tier status and any custom comfort scoring profiles you create — in our database.
Server and usage data
Our hosting infrastructure (Vercel) automatically collects standard web server data when you use the service. This may include:
- IP address
- Browser type and version
- Device type and operating system
- Pages visited, session duration, and timestamps
- Referral links
This data is retained per Vercel's standard log retention policy and is used solely for security, performance monitoring, and debugging. It is not used for advertising or sold to third parties.
Optional location data
If you choose to show your location on the map, your browser or device may ask for permission to share your current location with RailTrailWx. This location is used in your browser to display your position on the interactive map. We do not store your precise location in our database, use it for advertising, or sell it to third parties. You can deny or revoke location permission through your browser or device settings.
3. How We Use Your Data
- Authenticate and manage your account
- Store and apply your custom comfort scoring profiles to generate personalized forecasts
- Process subscription payments
- Send product updates if you opt in
- Monitor service performance, security, and reliability
- Display your location on the map when you explicitly request it
We do not sell, share, or use your personal data for advertising purposes.
4. Comfort Scoring Profiles
Your comfort threshold profiles are personal data. They are stored in our database and visible only to you and our infrastructure providers. Profiles are deleted automatically when your account is deleted.
5. Third-Party Services
RailTrailWx relies on the following third-party services, each of which may process some of your data as described:
- Clerk — handles authentication and stores your email and session data. See clerk.com/privacy.
- Stripe — processes subscription payments. Entrain Weather, LLC does not store your payment card details; they are handled directly by Stripe. See stripe.com/privacy.
- Vercel — hosts the application and may retain standard server logs (IP, user agent, timestamps) per their data retention policy. See vercel.com/legal/privacy-policy.
- Cloud database and infrastructure providers — store account and profile data in encrypted, access-controlled environments.
All third-party services are required to comply with applicable data protection regulations and process only the data necessary for their function.
6. Cookies
We use cookies only for authentication session management via Clerk. No advertising, tracking, or third-party analytics cookies are used. We do not use session recording tools or behavioral tracking services.
7. Data Retention
Your account data is retained while your account is active. You may request deletion at any time by emailing support@railtrailwx.com. Upon deletion, your account data and comfort profiles are removed from our database. Residual data in backups may persist for a limited period before being purged.
8. Children's Privacy
RailTrailWx is not directed at children under the age of 13. We do not knowingly collect personal data from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at support@railtrailwx.com and we will promptly delete that information.
9. Changes to This Policy
Entrain Weather, LLC may update this Privacy Policy from time to time. When we do, the effective date at the top of this page will be revised. For material changes, we will provide notice via the updates page or by email. Your continued use of RailTrailWx after changes take effect constitutes acceptance of the revised Privacy Policy.
