Free tier: Everything stays in your browser — no account, no server storage, no tracking.
Pro tier (€2.99/mo): We store your Strava athlete ID and subscription status on our server to verify Pro access. Payments are handled by Polar.sh — we never see your card details.
What we collect (free tier)
Strava access token — stored in your browser's sessionStorage only. Never sent to our servers after the initial OAuth exchange. Cleared when you close the tab or log out.
Your name and profile photo — displayed in the app. Never stored on a server.
GPS tracks — fetched on demand, processed in your browser to render the 3D video, then discarded. Never sent to our servers.
Strava API usage counters — stored in localStorage in your browser only, so we can show you your remaining API quota. Never transmitted.
What we collect (Pro tier)
Strava athlete ID — stored on our server (Netlify Blobs) to link your Polar subscription to your account. This is a numeric identifier, not your name or email.
Subscription status — active, canceled, or revoked — stored alongside the athlete ID.
Payment data — handled entirely by Polar.sh. We receive only a confirmation that your payment succeeded. We never see your card number, billing address, or any other financial information.
What we never do
Write to Strava — the permission is read-only. We cannot post activities, give kudos, or modify anything.
Use cookies or analytics — no Google Analytics, no Mixpanel, no fingerprinting.
Share your data with third parties — your data is never sold or rented.
Third-party services
Your browser contacts these services to render the map and process payment. Each has its own privacy policy.
If you are in the EU/EEA, you have the right to access, correct, or delete the data we hold about you (your Strava athlete ID and subscription status). To exercise these rights, email us at info@routerewind.com or open an issue on our GitHub page. We will respond within 30 days.
Data retention
Free tier: No data retained — everything is session-only in your browser.
Pro tier: Your athlete ID and subscription status are retained for as long as your subscription is active, and for up to 90 days after cancellation for audit purposes, then deleted.
