Last updated: 20 July 2026

Please read these Terms of Use (“Terms”) carefully before using Acuna. By downloading, accessing or using the Acuna application (“Acuna”, “the app”), you agree to these Terms. If you do not agree, do not use the app.

Acuna is published by Atlander, Unipessoal, Lda, registered in Portugal (NIF/NIPC 516934473), Avenida Valbom 17, 2.º D, 2750-508 Cascais, Portugal (“Atlander”, “we”, “us”). Contact: support@acuna.app.

1. Who may use Acuna

Acuna relates to alcohol consumption and is intended for adults only. You must be at least 18 years old, or the legal drinking age in your country if higher, to use the app.

2. Important health notice — please read

Acuna is a personal self-tracking tool that helps you record and observe your own alcohol consumption. Acuna is NOT a medical device and does NOT provide medical, clinical, psychological, or professional advice, diagnosis, or treatment.

  • Acuna does not diagnose, treat, cure, or prevent any disease or condition, including alcohol use disorder or dependence.
  • The information Acuna shows (such as estimated grams of alcohol, calories, targets, and trends) is for general informational and self-awareness purposes only, is based on the data you enter and standard estimates, and may not be accurate for your individual circumstances.
  • Acuna is not a substitute for the advice of a qualified doctor, therapist, or other health professional. Always seek the advice of a qualified professional with any questions you may have regarding alcohol use or your health.
  • Never disregard professional advice or delay seeking it because of something in the app.
  • If you are concerned about your drinking or think you may be dependent on alcohol, please speak to a healthcare professional or a specialist support service.
  • If you are in crisis or believe you may be experiencing a medical emergency, contact your local emergency services immediately.

You use Acuna and make decisions about your alcohol consumption at your own discretion and risk.

3. Your licence to use the app

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable licence to download and use one copy of Acuna on Apple devices that you own or control, for your personal, non-commercial use, in accordance with the App Store Terms of Service. This licence does not transfer any ownership rights to you.

4. Your data is yours and stays on your device

Acuna stores the entries you create only on your device. We do not receive, store, or have access to your diary. This means:

See our Privacy Policy for more detail.

5. Free trial and purchase

Acuna is free to use for a limited trial period of 14 days. After the trial, continued use requires a one-time in-app purchase that unlocks the app permanently (“lifetime unlock”).

Nothing in these Terms limits any statutory rights you may have as a consumer that cannot be excluded under applicable law.

6. Acceptable use

You agree not to: (a) copy, modify, or create derivative works of the app except as permitted by law; (b) reverse engineer, decompile, or attempt to extract the source code, except to the extent this restriction is prohibited by applicable law; (c) rent, lease, lend, sell, redistribute, or sublicense the app; (d) use the app for any unlawful purpose or in any way that could harm the app or others.

7. Intellectual property

The app, its content, design, and the “ACUNA” name and logo are owned by or licensed to Atlander and are protected by intellectual property laws. Except for the limited licence granted above, these Terms do not grant you any rights in our intellectual property.

8. Availability and changes

We may update, change, suspend, or discontinue the app or any of its features at any time, without liability, to the extent permitted by law. We do not guarantee that the app will always be available or error-free.

9. Disclaimers

To the maximum extent permitted by applicable law, the app is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the app’s calculations or information are accurate, complete, or suitable for your purposes. This section does not affect mandatory consumer warranties that cannot be excluded under applicable law.

10. Limitation of liability

To the maximum extent permitted by applicable law, Atlander will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, arising out of or relating to your use of, or inability to use, the app. Nothing in these Terms excludes or limits our liability where it would be unlawful to do so, including liability for death or personal injury caused by negligence, for fraud, or for any liability that cannot be excluded under applicable consumer law. Where our liability cannot be excluded but can be limited, it is limited to the amount you paid for the app.

11. Termination

These Terms apply until terminated. Your licence ends automatically if you fail to comply with them. You may end them at any time by deleting the app.

12. Governing law

These Terms are governed by the laws of Portugal, without prejudice to any mandatory consumer-protection rights you enjoy under the laws of your country of residence. Mandatory rights of consumers resident in the European Union are not affected.
