• Your account: email address and the rider name you choose.
• Emails: we email you when a friend invites you to a planned ride and shortly before it starts, plus sign-in and password-reset mail. These are delivered by Brevo on our behalf. You can switch ride emails off in Settings → Group rides. We never send promotional email.
• Phone notifications: in the iPhone app, if you allow notifications, we send the same two messages (an invite, and a reminder before a planned ride) through Apple. The app stores the notification token Apple gives your phone; it is deleted when you sign out. Switch them off any time in iPhone Settings → Notifications → Watt Cave.
• Your rides: power, heart rate, cadence, distance and summary numbers for rides you do in Watt Cave, so your history follows you across devices.
• Friends: the riders you are friends with, friend requests, and the group labels you give them.
• Settings such as FTP, weight, heart rate zones and coach preferences, so they follow you between devices.

• Your ride history and training numbers are visible only to you.
• Other signed-in riders can see your rider name, so they can find and add you.
• During a group ride, the riders in that ride see your live power, % of FTP, heart rate and cadence. Your FTP value itself is never shared.

Connecting Strava is optional. If you connect, Watt Cave asks Strava for permission to read your activities and upload activities.

• Uploads: rides you finish in Watt Cave are uploaded to your own Strava account (automatically, if you leave that switched on), or when you tap Upload.
• Imports: your Strava cycling activities are copied into your own Watt Cave history so your training charts include them.
• Your Strava data is shown only to you. It is never shown to other riders, never shared with anyone else, never sold, and never used for advertising or to train AI models.
• Strava access tokens are stored in your account record, readable only by you. The Strava app secret stays on our server.
• Disconnecting (Settings → Strava → Disconnect) revokes Watt Cave's access and deletes the stored tokens. You can also revoke access at strava.com → Settings → My Apps. Imported Strava rides can be deleted one by one from History, and are deleted with your account.

• Workouts you build or import are Private — only you can see them. A host's workout is shared with the riders in that group ride for the ride.
• If you choose Publish, you confirm it's your own workout and allow Watt Cave to publish a copy for all riders, credited with your rider name. A Watt Cave admin reviews every submission; nothing is published without approval.
• Changing or deleting your own copy later doesn't change the published one. Ask the Watt Cave team and a published workout will be removed.

Accounts and rides are stored with Supabase (database and sign-in) and the app runs on Cloudflare. We don't use advertising or third-party tracking.

You can delete any ride from History at any time. To delete your whole account and everything linked to it, go to Settings → Account → Delete my account. It takes effect immediately and can't be undone. You can also email us and we'll do it for you.
