These Terms and Conditions (“Terms”) govern the use of the Yucuna iOS application (“the App”) distributed on the Apple App Store. The Yucuna B2B web platform (Yucuna Dashboard) is governed by a separate agreement.

By downloading, installing, or using the App, you (“the User”) accept these Terms in full. If you do not agree, do not use the App.

Art. 1. Provider

The App is provided by:

Quattro Creative SARL

Registered in the Grand Duchy of Luxembourg
Registered Office: 24, rue Neuort – 8373 Hobscheid
RCS Luxembourg: B201267
Email: hello@wearequattro.com
Website: www.wearequattro.com

Art. 2. License

Quattro Creative grants the User a free, personal, non-exclusive, non-transferable, revocable license to install and use the App on Apple devices owned or controlled by the User, for personal and non-commercial purposes only.

All intellectual property rights in the App — including source code, design, graphics, brand assets, and the “Yucuna” name and logo — remain the exclusive property of Quattro Creative.

The User may not:

• copy, modify, decompile, reverse-engineer, or create derivative works of the App;
• redistribute, sublicense, sell, or rent the App;
• remove or alter any proprietary notice or branding;
• use the App in violation of applicable law or in a way that interferes with Apple’s services.

Use of the App is also subject to Apple’s Licensed Application End User License Agreement (apple.com/legal/internet-services/itunes/dev/stdeula). In case of conflict between Apple’s EULA and these Terms, the more restrictive provision shall apply.

Art. 3. Nature of the CO₂ Estimates

The CO₂ emission values displayed by the App are estimates calculated from publicly available industry data (including, but not limited to, Greenspector measurements and aggregate energy consumption rates for digital services).

These estimates are provided for informational and awareness purposes only. They are intended to give the User a general sense of the environmental impact associated with their phone usage.

The User acknowledges and agrees that:

• the App does not perform certified emissions measurements;
• the values shown may differ — sometimes significantly — from the actual emissions attributable to a specific device, network, or geographic location;
• -he data shall not be used for regulated reporting (ESG, GHG Protocol, CDP, CSRD, etc.), carbon accounting, formal audits, scientific publications, public claims, or any context requiring certified figures;
• Quattro Creative makes no warranty as to the accuracy, completeness, or fitness for any particular purpose of the displayed estimates.

Art. 4. Eco Mode and User Responsibility

The App includes an “Eco Mode” feature that allows the User to voluntarily restrict access to apps of their choice for a duration they choose, using Apple’s Family Controls and ManagedSettings frameworks.

The User is solely responsible for:

• selecting which apps to block;

• choosing the duration of each session;

• assessing whether the restriction is appropriate given their personal circumstances.

The App must not be used in situations where uninterrupted access to communication, navigation, emergency services, medical, financial, or any time-sensitive applications is required.

Quattro Creative shall not be liable for any direct or indirect consequence arising from the User’s voluntary self-restriction of app access through Eco Mode, including but not limited to missed calls, missed messages, missed alerts, missed navigation instructions, or any opportunity cost resulting from temporarily reduced access.

Art. 5. AI-Generated Content

The App offers personalized weekly summaries generated locally on the User’s device by Apple Intelligence (Apple’s on-device generative AI). The text produced is automatically generated and is not reviewed by Quattro Creative.

The User acknowledges and agrees that:

• AI-generated text may contain inaccuracies, omissions, or interpretations that do not reflect Quattro Creative’s positions;
• AI suggestions are not professional advice (medical, psychological, financial, legal, or otherwise);
• -he User is free to ignore, disregard, or contest any AI-generated content.

Quattro Creative is not liable for the specific phrasing or content of any AI-generated summary.

Art. 6. No Warranty

The App is provided “as is” and “as available”, without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, reliability, or uninterrupted operation.

Quattro Creative does not warrant that the App will be free of errors, that defects will be corrected, or that the App will be compatible with every device, iOS version, or configuration.

Art. 7. Limitation of Liability

To the maximum extent permitted by applicable law, Quattro Creative, its directors, employees, and partners shall not be liable for any indirect, incidental, special, consequential, or punitive damages — including loss of data, loss of profits, loss of opportunity, or reputational harm — arising out of or in connection with the use of, or inability to use, the App.

In any case, Quattro Creative’s total liability under these Terms shall not exceed fifty euros (EUR 50), except where such limitation is prohibited by law.

Nothing in these Terms excludes or limits liability for fraud, gross negligence, wilful misconduct, or any other liability that cannot be excluded under applicable law.

The above limitations do not affect the User’s mandatory consumer rights under Luxembourg or European Union law.

Art. 8. Service Availability and Modifications

Quattro Creative may, at any time and without prior notice:

• modify, update, or improve the App;
• add, change, or remove features;
• suspend or discontinue the App entirely.

Continued use of the App after an update constitutes acceptance of the modified version.

Art. 9. Termination 

The User may terminate this agreement at any time by uninstalling the App from their device.

Quattro Creative may revoke the license granted under Art. 2 with immediate effect if the User breaches these Terms.

Termination does not affect any rights or obligations that, by their nature, are intended to survive — including but not limited to Art. 2 (intellectual property), Art. 6 (no warranty), Art. 7 (limitation of liability), and Art. 10 (governing law).

Art. 10. Governing Law and Jurisdiction

These Terms are governed by and construed in accordance with the laws of the Grand Duchy of Luxembourg, without regard to its conflict-of-laws rules.

Any dispute arising out of or in connection with these Terms shall be subject to the exclusive jurisdiction of the courts of Luxembourg, without prejudice to the mandatory consumer protection rights the User may enjoy under the law of their country of residence within the European Union.
