Terms of use

Last updated November 15, 2026

These terms are an agreement between you and Jose Barbosa, who runs Terna (“we”, “us”). By creating an account or using Terna on iOS, Android or the web, you agree to them. If you don’t agree, please don’t use Terna.

1. Not medical advice

Terna gives general fitness and nutrition information: workout suggestions, calorie and macro targets, food estimates and recovery logs. It is not medical advice and is not a substitute for a doctor, physiotherapist or registered dietitian. Talk to a qualified professional before starting a new training or eating plan, especially if you are pregnant, injured, or have a medical condition. Terna is not a medical device and doesn’t diagnose, treat or monitor any condition.

2. Train at your own risk

Strength training carries a risk of injury. You decide what to lift and how much; use correct technique, warm up, use a spotter where appropriate, and stop if something hurts. Workout plans, progressions, strength ranks and recovery information are estimates built from what you log, and they can be wrong. Food and calorie numbers, including AI photo estimates, are approximate; check them before relying on them.

3. Your account

• You must be at least 16 to use Terna.
• Give accurate information and keep your password safe. You are responsible for activity on your account.
• You can delete your account at any time in the app (Settings › Delete account). Our privacy policy explains what that removes.

4. Acceptable use

Don’t misuse Terna: no attempts to break or overload the service, access other people’s data, reverse engineer it beyond what the law allows, scrape it, or use it for anything unlawful. Don’t upload content you don’t have the right to share.

5. Your content

Your workouts, food logs, photos and other data stay yours. You give us permission to store and process them only to run Terna for you, as described in the privacy policy.

6. Terna Pro and payments

• Terna is free to use. Terna Pro is an optional subscription that adds features such as unlimited AI photo logging.
• Pro is bought through the Apple App Store or Google Play, and those stores’ terms apply to the purchase. Payment is charged to your store account.
• Subscriptions renew automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel in your App Store or Google Play account settings; deleting your Terna account does not cancel it.
• Refunds are handled by Apple or Google under their policies.
• We may change Pro’s features or price. Price changes apply from your next renewal, with the notice the store requires.

7. Third-party data and services

Terna uses public food data (USDA FoodData Central and Open Food Facts), connects to Apple Health and Health Connect if you allow it, and imports files from other apps you choose. We aren’t responsible for the accuracy of third-party data or for those services.

8. Changes to Terna

Terna is under active development. We may add, change or remove features, and we may suspend the service for maintenance. We’ll try to give notice of changes that matter to you.

9. Ending your use

You can stop using Terna and delete your account at any time. We may suspend or close an account that breaks these terms or puts the service or other users at risk; where it’s reasonable, we’ll tell you first and give you a chance to export your data.

10. No warranty; limits of liability

Terna is provided “as is” and “as available”, without warranties of any kind, to the extent the law allows. We don’t promise that it will be uninterrupted, error-free, or that its estimates are accurate. To the extent the law allows, we are not liable for injury, loss of data, or indirect or consequential losses arising from your use of Terna, and our total liability is limited to the amount you paid for Terna Pro in the 12 months before the claim. Nothing in these terms limits liability that can’t be limited by law, or your rights as a consumer.

11. Changes to these terms

We may update these terms. We’ll change the date above and, for significant changes, tell you in the app or by email before they apply. Continuing to use Terna after that means you accept the new terms.
