Terms of Service

Quick Summary: WhatToLayer is a free app that gives plain-language clothing guidance based on the weather. It's helpful advice, not a guaranteed or official weather/safety service — always use your own judgment, especially in extreme cold or heat.

1. Acceptance of Terms

By downloading or using WhatToLayer (the "App"), you agree to these Terms of Service. If you do not agree, please do not use the App.

2. What WhatToLayer Does

WhatToLayer suggests what to wear outside based on weather forecasts and the activity you choose. It combines public weather data with a comfort model (wind chill, humidity, your pace and personal tolerance) to produce plain-language guidance.

Important — guidance, not a guarantee. WhatToLayer's recommendations are a helpful heuristic, not an official or certified weather, meteorological, or safety service. The "feels like" values are estimates, not certified indices. Forecasts can be wrong, and conditions can change quickly. Do not rely on WhatToLayer for life-safety decisions. In extreme cold, extreme heat, storms, or any situation where your health or safety is at risk, use your own judgment and consult official sources (e.g., your national weather service) and a medical professional where appropriate.

3. The App Is Provided "As Is"

The App is provided on an "as is" and "as available" basis, without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, or uninterrupted availability. We do not warrant that the forecasts, recommendations, or any output will be accurate, complete, or suitable for your circumstances.

4. Limitation of Liability

To the maximum extent permitted by law, WhatToLayer and its creators are not liable for any injury, loss, damage, or inconvenience arising from your use of (or reliance on) the App or its recommendations, including decisions about what to wear or whether to go outside. You use the App at your own risk.

8. Intellectual Property

The App, its name, design, and content are owned by us and protected by applicable law. These Terms do not grant you any ownership rights in the App.

9. Changes to These Terms

We may update these Terms from time to time. Changes will be posted on this page with a new "Last Updated" date. Continued use of the App after changes constitutes acceptance of the updated Terms.
