Terms of Service

Last updated: May 18, 2026

These Terms of Service ("Terms") govern your use of the Stututu mobile application (the "App") and the website at stututu.io (the "Site"), each provided by Smoking Tiger ("we", "us", or "our"). By downloading, installing, accessing, or using the App or Site, you agree to be bound by these Terms. If you do not agree, do not use the App or Site.

1. Eligibility

You must be at least 16 years old to use the App or Site. By using them, you represent that you meet this requirement and have the legal capacity to enter into these Terms. If you are using the App or Site on behalf of an organisation, you represent that you are authorised to bind that organisation to these Terms.

2. The Service

The App allows you to connect your iOS device to a compatible vehicle through a third-party OBD2 adapter to read live vehicle telemetry and measure performance characteristics. The Site provides information about the App. The Service is provided for personal, non-commercial use unless we expressly agree otherwise in writing.

3. App Store Terms

If you obtain the App through the Apple App Store, your use is also subject to Apple's Licensed Application End User License Agreement ("Apple EULA"). To the extent any Apple EULA term conflicts with these Terms in respect of the Apple-distributed App, the Apple EULA prevails for that conflict only. Apple is not a party to these Terms and has no obligation to provide maintenance or support for the App.

4. Licence to Use the App

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, revocable licence to install and use the App on a device that you own or control, solely for your own personal use. You may not:

• Copy, modify, translate, or create derivative works of the App, except as permitted by applicable law;
• Reverse engineer, decompile, or disassemble the App, except where such restriction is prohibited by law;
• Rent, lease, sell, sublicense, or otherwise transfer the App to a third party;
• Remove or alter any proprietary notices;
• Use the App in a manner that violates any law, regulation, or third-party right.

5. Your Responsibilities

You are solely responsible for your use of the App and Site. You agree to:

• Comply with all applicable laws and regulations, including traffic and road-safety laws in your jurisdiction;
• Never operate the App in a way that distracts you from safely driving — do not interact with the App while the vehicle is moving;
• Use only OBD2 adapters and accessories that are compatible with your vehicle and authorised by the relevant authorities;
• Ensure that any use of the App with a vehicle is permitted by the vehicle owner and applicable manufacturer warranties;
• Keep your device and credentials secure.

6. Important Safety Disclaimers

6.1 The App is not a diagnostic device.

The App is an informational tool. It is not a certified medical, automotive, or safety-critical diagnostic device, and it does not replace inspection by a qualified mechanic or any official emissions, safety, or regulatory test. Any readings, scores, or interpretations are for informational purposes only and may be inaccurate, incomplete, or delayed. Do not rely on the App for diagnostic, repair, regulatory, or safety decisions.

6.2 Performance measurement is for closed-circuit use only.

Any performance-measurement feature (including acceleration, speed, or lap-time measurements) is intended for use on a closed circuit or otherwise legally permitted test environment. You must never use these features in a way that violates traffic laws, posted speed limits, or rules applicable to public roads. All responsibility for the manner, location, and consequences of any performance test lies with you, the driver.

6.3 Vehicle and equipment risk.

Connecting third-party hardware to a vehicle's OBD2 port carries inherent risk, including potential interference with vehicle electronics. We do not manufacture, sell, or certify OBD2 adapters and are not responsible for damage to your vehicle, adapter, device, or property resulting from the use of any adapter or from the App. You assume all such risks and remain responsible for ensuring compatibility and safe operation.

7. In-App Purchases and Subscriptions

The App may offer optional paid features, including one-time purchases or auto-renewing subscriptions. All transactions are processed by Apple under its standard payment terms; we do not handle your payment details. Prices, billing cycles, and renewal terms are disclosed at the point of purchase. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period, in accordance with Apple's policies. You can manage or cancel subscriptions in your Apple ID settings. Statutory consumer rights, including any mandatory right of withdrawal under applicable law (e.g., the EU consumer-rights directive), are not affected by these Terms.

8. Third-Party Services and Content

The App may interoperate with, link to, or depend on services and content provided by third parties (for example, OBD2 adapter manufacturers, Apple, and infrastructure providers such as Google Firebase). We are not responsible for the availability, accuracy, content, terms, or practices of any third party. Your use of any third-party service is governed by that third party's own terms and policies.

9. Intellectual Property

The App, the Site, and all related materials — including software, design, text, graphics, logos, and trademarks — are owned by Smoking Tiger or its licensors and are protected by applicable intellectual-property laws. Except for the licence granted in Section 4, no rights are granted to you. Open-source components included in the App are governed by their respective licences, which are listed in the App and at stututu.io/acknowledgements where available.

10. User Content and Feedback

If you send us suggestions, ideas, or feedback ("Feedback"), you grant us a worldwide, perpetual, irrevocable, royalty-free, sublicensable licence to use the Feedback for any purpose, including improving the App and Site, without obligation or compensation.

11. Privacy

Our handling of personal data is described in our Privacy Policy, which forms part of these Terms.

12. Updates and Changes to the App

We may release updates, modifications, or new versions of the App or Site, and may add, change, or remove features at any time without notice. Some features may require updates to your device's operating system, and continued use of older versions may not be supported.

13. Suspension and Termination

You may stop using the App at any time by deleting it from your device. We may suspend or terminate your access to the App or Site, in whole or in part, at any time and without notice if we believe you have violated these Terms or applicable law, or if continued provision would create legal or operational risk. Sections that by their nature should survive termination — including Sections 6, 9, 14, 15, 16, 17, and 19 — will survive.

14. Disclaimer of Warranties

To the maximum extent permitted by applicable law, the App and Site are provided "as is" and "as available", without any warranty of any kind, whether express, implied, or statutory, including any warranties of merchantability, fitness for a particular purpose, accuracy, reliability, non-infringement, or that the App or Site will be uninterrupted, secure, or error-free. We do not warrant that the App is compatible with any specific vehicle, adapter, or use case. Nothing in this Section limits any non-excludable statutory rights you may have as a consumer.

15. Limitation of Liability

To the maximum extent permitted by applicable law, neither Smoking Tiger nor its affiliates, officers, employees, or licensors will be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or other intangible losses, arising out of or in connection with your use of (or inability to use) the App or Site, even if advised of the possibility of such damages.

To the extent that liability cannot be excluded by law, our total aggregate liability for any claim arising out of or in connection with the App, Site, or these Terms will not exceed the greater of (a) the amount you paid us in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) one hundred euros (EUR 100).

Nothing in these Terms limits or excludes any liability that cannot be limited or excluded under applicable law, including liability for death or personal injury caused by negligence, fraud, or fraudulent misrepresentation, or any mandatory liability under product-liability or consumer-protection legislation.

16. Indemnification

To the extent permitted by applicable law, you agree to indemnify and hold harmless Smoking Tiger and its affiliates from and against any claims, damages, losses, liabilities, and reasonable expenses (including legal fees) arising out of or related to: (a) your use or misuse of the App or Site; (b) your violation of these Terms; (c) your violation of any law or third-party right; or (d) your operation of any vehicle in connection with the App.

17. Governing Law and Dispute Resolution

These Terms are governed by the laws of the Federal Republic of Germany, without regard to its conflict-of-laws principles. The application of the United Nations Convention on Contracts for the International Sale of Goods is excluded.

If you are a consumer resident in the European Union, this choice of law does not deprive you of the protection of mandatory provisions of the law of your country of residence, and you may bring proceedings in the courts of that country. Subject to the foregoing, the courts of our registered seat in Germany have non-exclusive jurisdiction over any dispute arising out of or in connection with these Terms.

The European Commission provides an online dispute resolution platform at ec.europa.eu/consumers/odr. We are not obliged and do not commit to participate in alternative dispute resolution proceedings before a consumer arbitration board.

18. Changes to These Terms

We may modify these Terms from time to time. When we do, we will update the "Last updated" date at the top of this page. Material changes will be communicated through the App or Site where appropriate. Your continued use of the App or Site after changes take effect constitutes your acceptance of the updated Terms.

19. Miscellaneous

Entire agreement. These Terms, together with the Privacy Policy and any additional terms presented at the point of use, constitute the entire agreement between you and us regarding the App and Site, and supersede any prior agreements on the same subject.

Severability. If any provision of these Terms is held unenforceable, the remaining provisions remain in full effect, and the unenforceable provision will be replaced by an enforceable one that most closely reflects the original intent.

No waiver. Our failure to enforce a right or provision of these Terms is not a waiver of that right or provision.

Assignment. You may not assign or transfer your rights under these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.

No agency. No partnership, agency, joint venture, or employment relationship is created by these Terms.

Force majeure. We are not liable for any failure or delay in performance caused by circumstances beyond our reasonable control.
