By creating an account or using WTF (the "app"), you agree to these Terms of Service ("Terms"). If you don't agree, don't use the app. We may update these Terms occasionally; if we do, we'll update the "last updated" date and notify you in the app of material changes.
These Terms are between you and the operators of WTF, accessible at jerhud.com. In these Terms, "we," "us," and "our" mean us. "You" and "your" mean you, the user.
You must be at least 13 years old to use WTF (or 16 if you're in the European Economic Area, the United Kingdom, or Switzerland). If you're under 18, you should review these Terms with a parent or guardian. We don't knowingly accept registrations from anyone under these age limits — if we discover that an account was created by someone underage, we'll terminate it.
By using the app, you represent that you meet the age requirement and that you're using WTF for lawful, personal purposes.
To use most features of WTF, you create an account. You're responsible for:
You can delete your account at any time from inside the app (Settings → Delete Account). When you delete your account, your personal data is removed from our active systems within 30 days, as described in our Privacy Policy.
We are not your doctor, dietitian, physical therapist, or licensed fitness trainer. The workouts, nutrition information, and recommendations the app generates are educational and illustrative — they're a starting point, not a prescription.
Before starting any new exercise program, talk to a qualified healthcare provider, especially if you:
If you experience pain, lightheadedness, chest discomfort, or any other concerning symptom while using the app, stop and seek medical advice. You exercise at your own risk. Use good judgment, listen to your body, and prioritize your safety over completing a workout.
You agree not to:
If you violate these rules, we may suspend or terminate your account. Serious violations may also be reported to law enforcement.
The data you log in WTF — your workouts, nutrition entries, body measurements, notes, and so on — is your content. You own it. By using the app, you give us a limited license to store, process, and display it back to you for the purpose of running the service. We don't claim ownership of your content, and we don't use it to train AI or sell to third parties (see the Privacy Policy for details).
The app itself, including its design, code, text, graphics, exercise library, plan-generation logic, the WTF brand, and any related materials, is owned by us or our licensors and is protected by copyright, trademark, and other laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the app for your personal, non-commercial use, subject to these Terms.
You can't copy, modify, distribute, sell, or lease any part of the app or its content. You can't use the WTF name or logo without our written permission.
Some features of WTF may require a paid subscription ("WTF Pro" or similar). If you purchase a subscription:
Subscriptions purchased through Apple's App Store are subject to Apple's terms in addition to ours. We don't process or store credit card information for App Store purchases — Apple does.
WTF works with third-party services like Apple, Google, HostGator, Resend, Firebase, and PostHog. We're not responsible for those services' content, terms, or actions. When you use a third-party feature (like signing in with Apple), you're also subject to that third party's terms.
We work hard to keep WTF available, but we don't guarantee uninterrupted service. We may need to take the app down for maintenance, updates, or due to circumstances beyond our control. We may also change, add, or remove features over time. If we make a significant change that affects you, we'll do our best to give you reasonable notice.
We reserve the right to discontinue the app at any time. If we shut down the service entirely, we'll give you reasonable notice and a way to export your data first.
You can stop using WTF at any time by deleting your account. We can suspend or terminate your access if you violate these Terms, if your account is inactive for an extended period, or if we decide to discontinue the service. When your account is terminated, the license we granted you ends immediately, and the rest of these Terms continue to apply where they make sense (intellectual property, disclaimers, limitations of liability, etc.).
WTF is provided "as is" and "as available." We make no warranties — express, implied, or statutory — about the app, including warranties of merchantability, fitness for a particular purpose, non-infringement, or that the app will be uninterrupted, error-free, secure, or accurate.
Specifically, we don't warrant that:
Some jurisdictions don't allow certain warranty disclaimers, so some of these may not apply to you.
To the fullest extent permitted by law, we and our affiliates, officers, employees, and contractors will not be liable for any indirect, incidental, consequential, special, or punitive damages — including lost profits, lost data, or personal injury — arising out of or relating to your use of WTF, even if we knew the damages were possible.
Our total liability to you for any claim arising out of these Terms or your use of the app is limited to the greater of: (a) the amount you paid us in the 12 months before the claim, or (b) USD $100.
Some jurisdictions don't allow certain liability limitations, so some of these may not apply to you. Nothing in these Terms limits our liability for things that can't legally be limited (like gross negligence or fraud).
You agree to defend, indemnify, and hold us harmless from any claims, damages, losses, or expenses (including reasonable attorneys' fees) arising out of: (a) your use of the app, (b) your violation of these Terms, (c) your violation of any law or third-party right, or (d) any content you submit through the app.
These Terms are governed by the laws of the State of Arizona and the United States, without regard to conflict of law principles. Any dispute that can't be resolved informally will be brought in the federal or state courts located in Arizona, and you consent to the personal jurisdiction of those courts.
Before filing a lawsuit, please contact us at jeremy@jerhud.com — most disputes can be resolved quickly through direct communication.
If you downloaded WTF from Apple's App Store, the following also applies: these Terms are between you and us, not Apple. Apple has no obligation to provide support for WTF. Apple is a third-party beneficiary of these Terms with the right to enforce them. You represent that you're not located in a country subject to a US embargo and not on any US government list of prohibited or restricted parties.
These Terms (together with the Privacy Policy) are the entire agreement between you and us about WTF. If any part of these Terms is found to be unenforceable, the rest stays in effect. Our failure to enforce any provision doesn't waive that provision. You can't assign these Terms without our consent; we can assign them as part of a merger, acquisition, or sale of our assets.
