Terms of Service

1. Who can use Ferno

You must be at least 18 years old and able to form a binding contract. By creating an account or using Ferno, you agree to these terms and to our Privacy Policy.

2. Ferno is not medical advice

Ferno gives general nutrition and habit coaching for healthy adults. It is not a doctor, dietitian, or medical device, and it doesn’t diagnose, treat, or prevent any disease.

• Talk to a healthcare professional before starting any weight-loss program — especially if you are pregnant or breastfeeding, have diabetes, heart or kidney disease, take medication affected by diet, or have a history of disordered eating.
• Calorie and nutrition numbers are estimates. Photo and voice estimates in particular can be wrong; check anything that matters to you.
• Ferno won’t recommend daily targets below common safety minimums or goal weights below a healthy range, but you are responsible for your own choices. Stop and seek professional help if you feel unwell.
• In an emergency, call your local emergency number. Ferno can’t help in a crisis.

3. Your account

You sign in with Apple or with a one-time code sent to your email — no passwords. Keep access to your email and devices secure; you’re responsible for activity on your account. Tell us at support@getferno.com if you think someone else has accessed it.

4. Subscriptions and the free trial

• Ferno offers a 3-day free trial, then a paid subscription: $24.99 per month or $9.99 per week (prices in USD; local prices and taxes may vary by store and country).
• Subscriptions are purchased and billed through the Apple App Store or Google Play, and managed with our provider RevenueCat. Payment is charged to your store account when you confirm the purchase or when the trial ends.
• Subscriptions renew automatically unless you cancel at least 24 hours before the end of the current period. Cancel anytime in your device’s subscription settings; you keep access until the period ends.
• If you cancel during the free trial, you won’t be charged. Any unused part of a free trial ends when you buy a subscription.
• Refunds are handled by Apple or Google under their policies. We can’t issue refunds for store purchases directly, but we’re happy to help you ask.
• If we change prices, we’ll give you notice in advance and the change applies from your next renewal.

5. Your content

Your meals, photos, messages, and logs belong to you. You give us permission to store and process them only to run Ferno for you — including sending them to our AI provider to generate coaching, as described in the Privacy Policy. You can delete your content or your whole account at any time.

6. AI-generated coaching

Ferno’s replies, meal estimates, and plans are generated by AI. They can be incomplete, inaccurate, or not right for you. Use your judgment, and don’t rely on Ferno for decisions where accuracy is critical to your health.

7. Fair use

Please don’t:

• use Ferno for anyone other than yourself, or share or resell your account;
• try to break, overload, reverse-engineer, or scrape the service;
• upload content that’s illegal, harmful, or that you don’t have the right to share;
• use Ferno to promote or pursue dangerous weight-loss practices.

We may suspend accounts that break these rules or put others at risk.

8. Ending things

You can stop using Ferno and delete your account at any time from the app (You → Privacy → Delete everything). Deleting your account doesn’t cancel a store subscription — cancel that in your device’s settings too. We may end or suspend access if you seriously or repeatedly break these terms, and we’ll tell you why when we can.

9. Changes to Ferno and these terms

Ferno will keep changing as we improve it. If we change these terms in a meaningful way, we’ll notify you in the app or by email before the changes take effect. Continuing to use Ferno after that means you accept the new terms.

10. Disclaimers and liability

Ferno is provided “as is” and “as available.” To the extent the law allows, we disclaim implied warranties (like fitness for a particular purpose) and we aren’t liable for indirect or consequential losses. Our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. Nothing here limits rights you have under consumer protection laws that can’t be waived.

11. App store terms

If you downloaded Ferno from the Apple App Store, you also agree to Apple’s Licensed Application End User License Agreement. Apple isn’t responsible for Ferno or its support, and Apple and its subsidiaries are third-party beneficiaries of these terms. The same applies to Google if you downloaded Ferno from Google Play.
