Overview
Windy Ways is a tool for cyclists to find tailwind-friendly cycling segments. This page explains what data we access, how we use it, and how you can control it.
Data we access
When you connect your Strava account, Windy Ways requests the following data:
- Your basic Strava profile (name, profile picture, athlete ID)
- Your starred segments and segments near locations you search
- Your saved routes and the segments they contain
- Your recent activities (used only when you explicitly view activity-based wind analysis)
We also collect the location you choose for analysis (either via geolocation, search, or a shared link). We use the OpenWeatherMap API to fetch wind and weather data for that location.
How we use it
- To rank cycling segments by current and forecasted wind benefit
- To analyze your routes and show wind conditions for each segment
- To remember your preferences (location, units, bookmarks) across sessions
- To display your name and profile picture in the app while signed in
Your Strava data is never sold, shared with advertisers, or used for any purpose other than providing this service to you.
Where data is stored
Authentication tokens (Strava access & refresh tokens) are stored in your browser's session storage. They are cleared when you sign out or close all tabs.
When you sign in, we store the following in our database (Supabase): your Strava athlete ID, first and last name, profile picture URL, account creation timestamp, and any preferences you set (default location, average cycling speed) and segments you bookmark. We do not store your Strava access token or any of your activities. Cached segment and route data is held temporarily on our servers to reduce calls to the Strava API.
Recently fetched segments are also cached in your browser's localStorage so the app loads quickly between visits.
Third-party services
- Strava — Used for authentication, segment data, and route data. See Strava's Privacy Policy.
- OpenWeatherMap — Used for current weather and forecast data based on your selected location.
- Open-Meteo — Used for historical weather data when analyzing past activities.
- OpenStreetMap / CartoDB — Used for map tiles displayed in the app.
- Supabase — Used as the database for user preferences and bookmarks.
- Vercel — Hosts the application and provides cookieless usage analytics in aggregate.
Your control
You can:
- Sign out at any time from the profile menu, which clears your session
