Superhuman Badminton ("the app") is a badminton training app. We designed it to collect as little data as possible.
Your training data stays on your device. Your profile (training preferences, injuries you flag, schedule), workout history, streaks, XP and badges are stored locally on your device.
Account. To save your plan you create an account with an email address and password. Authentication is handled by Supabase, our authentication provider, which stores your email and a securely hashed password so you can sign back in. We do not receive or store your password in readable form.
Product analytics. We use PostHog to understand how the app is used (for example: onboarding completed, a workout finished, the paywall viewed) so we can improve it. Events are tied to your account ID and email. We do not sell this data or use it for advertising. See PostHog's privacy policy.
Subscription data. Purchases are processed by Apple App Store / Google Play and managed through RevenueCat. RevenueCat receives an anonymous app user ID and purchase receipts to validate your subscription. They do not receive your training data. See RevenueCat's privacy policy.
No ads, no ad tracking, no selling of data. No access to contacts, location, camera, microphone, or photos.
Training reminders are local notifications scheduled on your device on the days you selected. They can be disabled anytime in your device settings or in the app's Settings tab.
Uninstalling the app, or using "Reset everything" in Settings, permanently deletes all locally stored training data. To delete your account and its analytics records, contact us at the address below. Subscription records held by Apple/Google/RevenueCat are subject to their retention policies.
The app is not directed at children under 13.
