Terms of Service
These Terms of Service are also the End User License Agreement for the Engine app. Section 13 sets out the licence you are granted and the additional terms that apply when you download Engine from the App Store.
1. Agreement to Terms
By downloading, accessing, or using the Engine app or tryengine.app (together, the "Service"), you agree to these Terms of Service. If you don't agree, don't use the Service.
Engine is provided by Vinny Drumond ("Engine," "we," "us," "our").
2. Eligibility
You must be at least 16 years old to use Engine. By using the Service, you confirm you meet this requirement. If we learn that someone under 16 is using Engine, we'll take steps to close that account.
3. Your account
Some features require an account. You're responsible for keeping your login credentials secure and for all activity under your account. Tell us right away at info@tryengine.app if you suspect unauthorized access.
You can delete your account and your personal data at any time, directly in the app (Profile settings). This permanently deletes your account; it isn't just a deactivation. You can also reach us at info@tryengine.app if you'd rather request deletion by email.
4. Engine Pro subscriptions
Engine Pro is a recurring subscription, priced as shown in the app at the time you subscribe. Before you are charged, the app shows you the price and the billing period.
- Payments are processed by Stripe. Engine never receives or stores your card details.
- Your subscription renews automatically at the end of each billing period, and your payment method is charged each time, until you cancel.
- You can cancel at any time from Profile settings in the app, which opens Stripe's billing page. Cancelling stops future charges; your Pro access continues until the end of the period you have already paid for.
- If we offer a free trial, your paid subscription begins automatically when the trial ends unless you cancel before then.
- We may change subscription pricing going forward. We'll give you notice before any change affects your existing subscription.
- Except where the law requires otherwise, payments already made are non-refundable. If something has gone wrong, email us at info@tryengine.app — we'd rather sort it out than stand behind this sentence.
If we later add subscriptions or purchases through the App Store or Google Play, those stores' payment, cancellation, and refund rules will apply to purchases made that way, and we will update these Terms before that happens.
5. Specialty programs, and what happens if you cancel
Engine has two separate things you can pay for, and they behave differently on purpose.
- Specialty programs bought individually (such as the 12-Week Hybrid Shred) are one-time purchases at the price shown at the time of purchase. A program you buy is yours permanently. It does not expire, and it stays available to you whether or not you have an Engine Pro subscription.
- Engine Pro gives you access to every feature and every specialty program in the catalog for as long as your subscription is active. Starting a specialty program under Pro is not the same as buying it: access to it lasts as long as your subscription does.
If your subscription ends, you keep the free features and anything you bought outright. Training programs and meal plans that were generated for you while you were subscribed are kept, not deleted, but you will not be able to open them while you are not subscribed. If you subscribe again, they become available again as they were, and any specialty program you had started picks up where it left off.
6. AI-generated content
Several Engine features — "Make Me a Program," "Make Me a Workout," meal plans, and logging food from a photo or your voice — produce their results using third-party AI models. You should know what that means:
- These results are generated by a machine. They are not written or reviewed by Vinny, or by any coach, dietitian, or medical professional, before you see them.
- They can be wrong. A generated program may include an exercise that isn't right for you; estimated calories and macros from a photo or description are approximations and can be significantly off.
- They are general information, not personalized medical, dietary, or training prescriptions. Section 8 applies to them in full.
- Use your own judgement, and don't use a generated plan as a substitute for advice from a qualified professional who knows your circumstances.
To produce these results, the content you submit for that feature is sent to our AI providers. Our Privacy Policy explains exactly what is sent and to whom.
7. Acceptable use
You agree not to:
- Use Engine for any unlawful purpose
- Attempt to reverse-engineer, decompile, or extract the app's source code
- Interfere with or disrupt the Service, including attempting to access accounts or data that aren't yours
- Post abusive, harassing, or inappropriate content to the in-app community feed
- Impersonate another person or misrepresent your affiliation with anyone
- Use the AI features to generate content that is unlawful, or to attempt to extract the underlying prompts or models
We can suspend or terminate accounts that violate these terms.
8. Health and fitness disclaimer: please read this
Engine is not a medical device, and nothing in the app is medical advice. The training programs, nutrition guidance, macro calculations, and recovery recommendations in Engine — whether written by Vinny or generated by AI — are for general informational and educational purposes only.
- Talk to your doctor before starting any exercise or nutrition program, especially if you have any pre-existing medical condition, injury, are pregnant, or are otherwise at elevated risk from physical activity or changes in diet.
- You are solely responsible for judging your own physical condition and capabilities, and for stopping any activity that causes pain, dizziness, or discomfort.
- Exercise carries inherent risk of injury. By using Engine, you voluntarily assume all risks associated with physical exercise and dietary changes undertaken based on information in the app, to the fullest extent permitted by law.
- Macro and calorie calculations are estimates based on standard formulas and the information you provide; they are not personalized medical or dietary prescriptions.
- Entering an injury when generating a program does not mean the resulting program is safe for that injury. It is one input to a machine-generated suggestion, not a clinical assessment.
- If you experience a medical emergency, contact emergency services immediately. Do not rely on the app.
9. Your content, and the community feed
You retain ownership of everything you log or upload — workouts, photos, notes, and posts.
Engine keeps what you log private to your account, with one exception you control. When you choose to share an activity to the in-app community feed, that post — including your display name — becomes visible to every other signed-in Engine user. Sharing is off by default and is chosen one post at a time. By posting to the feed you grant Engine a non-exclusive licence to display that content to other users as part of the Service's normal operation. Deleting your post removes it for everyone, and is how you withdraw it. You're responsible for making sure you have the right to share anything you post.
10. Our content
The Engine app, its design, the training programs, and all associated content are owned by Engine or its licensors and protected by copyright and other intellectual property laws. You may use them for your personal, non-commercial use only. You may not copy, redistribute, or resell any program or content from Engine without our written permission.
11. Third-party services
Engine relies on third-party services to provide parts of the Service, including Supabase, Railway, Stripe, Anthropic, OpenAI, USDA FoodData Central, FatSecret, Resend, and Apple. We aren't responsible for the availability or practices of those services, which have their own terms and privacy policies. The current list, and what each one receives, is in our Privacy Policy.
12. Disclaimers and limitation of liability
The Service is provided "as is" and "as available," without warranties of any kind, express or implied. We don't guarantee the Service will be uninterrupted, error-free, or that any particular fitness or health outcome will result from using it.
To the fullest extent permitted by law, Engine and its owner are not liable for any indirect, incidental, special, or consequential damages arising from your use of the Service, including but not limited to injury, illness, or loss of data. Our total liability for any claim related to the Service is limited to the amount you paid us in the twelve months before the claim arose.
Some jurisdictions don't allow certain liability limitations, so some of the above may not apply to you.
13. Licence to use the app (End User License Agreement)
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable licence to install and use the Engine app on devices you own or control, for your personal, non-commercial use. We reserve all rights not expressly granted.
Additional terms for apps downloaded from the App Store. If you obtained Engine from Apple's App Store, the following also applies, and Apple requires us to state it:
- These Terms are between you and Engine only, not with Apple. Engine, not Apple, is solely responsible for the app and its content.
- Your licence to use the app is limited to a non-transferable licence to use it on any Apple-branded products that you own or control, as permitted by the Usage Rules in the App Store Terms of Service.
- Apple has no obligation whatsoever to furnish any maintenance or support services for the app. Any questions go to info@tryengine.app.
- Engine is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the app to you (if any); to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.
- Engine, not Apple, is responsible for addressing any claims relating to the app, including product liability claims, any claim that the app fails to conform to a legal or regulatory requirement, and claims arising under consumer protection, privacy, or similar legislation.
- Engine, not Apple, is responsible for the investigation, defence, settlement, and discharge of any third-party claim that the app infringes that third party's intellectual property rights.
- You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
- You must comply with any applicable third-party terms of agreement when using the app.
- Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of them, Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary.
The developer of Engine, for support and any other enquiry, is Vinny Drumond, contactable at info@tryengine.app.
14. Dispute resolution
Before filing a claim against Engine, you agree to contact us at info@tryengine.app so we can try to resolve the issue informally.
15. Governing law
These Terms are governed by the laws of the State of Florida, without regard to conflict-of-law principles, except where applicable law requires otherwise.
16. Changes to these Terms
We may update these Terms as Engine evolves. We'll update the date above, and for material changes we'll provide notice in the app before they take effect. Continuing to use Engine after changes take effect means you accept the updated Terms.
