Plain English summary: Use SuperFlex for your own training. Do not misuse it or try to break it. Subscriptions are managed through Apple and are non-refundable except where required by law. We can terminate accounts that violate these terms.

1. Acceptance of Terms

By downloading, installing, or using the SuperFlex application or visiting superflex.fit ("the Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, do not use the Service.

These Terms constitute a legal agreement between you and SuperFlex.Fit ("SuperFlex", "we", "us", or "our"). We may update these Terms from time to time; continued use of the Service after changes are posted constitutes acceptance of the updated Terms.

2. Eligibility

You must be at least 13 years old to use SuperFlex. If you are under 18, you represent that a parent or legal guardian has reviewed and agreed to these Terms on your behalf. By using the Service, you represent that you meet these requirements.

3. Your Account

You are responsible for maintaining the security of your account credentials. Do not share your password. You are responsible for all activity that occurs under your account. Notify us immediately at support@superflex.fit if you suspect unauthorized access.

You may delete your account at any time from Settings -> Account Deletion within the app.

4. Subscriptions and Billing

SuperFlex offers a free tier and optional paid plans, including SuperFlex Pro Monthly, SuperFlex Pro Yearly, and SuperFlex Pro Lifetime, where available. Monthly and Yearly plans are auto-renewable subscriptions processed through Apple's App Store. Lifetime Pro is a one-time in-app purchase and does not renew. RevenueCat helps us load available offerings, process entitlement status, and keep your SuperFlex account in sync with your App Store purchase state.

  • Billing — Your Apple ID account will be charged at the confirmed price shown in the App Store purchase sheet at the time of purchase and, for auto-renewing subscriptions, at the start of each renewal period.
  • Auto-renewal — Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current billing period.
  • Cancellation — Cancel anytime via iOS Settings -> [Your Name] -> Subscriptions. Cancellation takes effect at the end of the current billing period; no partial refunds are issued for unused time except where required by applicable law.
  • Free trials or promotions — Where offered, a trial or promotional offer follows the terms shown in the App Store purchase sheet and may convert to a paid subscription unless cancelled before the trial ends.
  • Price changes — We will notify you of price changes before they take effect, consistent with Apple's policies.
  • Refunds — All refund requests are handled by Apple in accordance with their App Store refund policy.
  • Payment details — We do not receive your payment card number, bank account number, or Apple ID payment credentials.
