AthliFuel – Terms of Service

Effective: 18 September 2026

These Terms of Service (“Terms”) govern your use of the AthliFuel mobile application, website and related services (together, the “Service”). The Service is operated by the individual identified in our Imprint (“AthliFuel”, “we”, “us” or “our”).

1. Acceptance of These Terms

By creating an account or using the Service, you enter into an agreement with us and agree to these Terms. If you do not agree, do not create an account or use the Service.

Our Privacy Policy explains how we process personal data. Any terms imposed by the app marketplace through which you downloaded the App may also apply.

2. Eligibility

You must be at least 18 years old and legally capable of entering into a binding agreement to use AthliFuel. The Service is not directed to children or minors.

3. The AthliFuel Service

AthliFuel helps users plan and track fitness and nutrition. Depending on the available features, you may be able to:

• Log workouts, physical activities, meals and nutrition information
• View activity, nutrition and progress summaries
• Receive personalized, non-medical calorie and macro-nutrient estimates
• Use additional functionality included in a free or paid subscription tier

Recommendations and estimates may use information such as your age, sex or gender selection, height, weight, goals, recorded meals, activities and training demands. Available features may differ by device, operating system, country, subscription tier or app version.

4. Your Account

You agree to:

• Provide accurate and current account information
• Keep your login credentials confidential and secure
• Promptly notify us if you suspect unauthorized access
• Remain responsible for activity performed through your account where legally permitted

You may not share, sell or transfer your account to another person.

5. Free Features and Subscriptions

5.1 Free features

AthliFuel may provide certain features without charge. We may introduce, remove or change free features in accordance with Section 13 and applicable law.

5.2 Paid subscriptions

Certain features may require a recurring subscription. The price, billing period, included features and any trial conditions will be shown before you confirm the purchase.

Subscriptions purchased through an app marketplace are billed and managed by that marketplace under its payment terms. Unless stated otherwise at purchase, subscriptions renew automatically for the selected billing period until cancelled through the relevant marketplace account settings. To avoid the next charge, cancel before the renewal time shown by the marketplace.

Cancellation stops future renewal but normally does not end access to paid features before the end of the current paid billing period. Refunds are handled by the marketplace through which the purchase was made, subject to its rules and your mandatory statutory rights.

5.3 Price changes

Any subscription price change will be communicated in advance and will take effect no earlier than the next permitted renewal. Where required, the marketplace will request your agreement. You may cancel before the new price applies. A price change does not affect an already-paid period.

6. Health and Medical Disclaimer

AthliFuel is a general fitness and nutrition tool. It does not provide medical advice.

• The Service is not a medical device and is not intended to diagnose, treat, cure or prevent any disease
• Calorie, macro-nutrient, hydration and activity outputs are estimates and may not suit your individual needs
• The Service does not replace advice from a doctor, registered dietitian or other qualified professional
• You remain responsible for deciding whether an activity or nutrition choice is appropriate for you

Consult an appropriately qualified professional before making material health, dietary or exercise changes, particularly if you have a medical condition, are pregnant, take medication, have a history of disordered eating or experience concerning symptoms. Stop exercising and seek appropriate help if you experience pain, faintness, chest discomfort or other warning signs.

Nothing in this Section limits liability that cannot lawfully be limited.

7. Your Content and Personal Data

You retain ownership of the workout, meal, note and other content you enter into the Service (“User Content”). You grant us a limited, non-exclusive licence to host, reproduce, process and display User Content only as necessary to operate, secure and improve the Service and to provide features you request. This licence ends when the relevant content is deleted, except where temporary technical copies or legally required retention remain necessary.

Personal data is processed as described in our Privacy Policy. These Terms do not replace that policy or request consent where another legal basis applies.

8. Acceptable Use

You must not:

• Use the Service unlawfully, fraudulently or to harm another person
• Access or attempt to access another user’s account or data without authorization
• Interfere with, overload, probe or circumvent the Service’s security or technical restrictions
• Upload malicious code or use automated means that place an unreasonable burden on the Service
• Copy, modify, decompile or reverse engineer the App except to the extent permitted by mandatory law
• Use the Service to develop or train a competing product through unauthorized access or extraction

9. Intellectual Property

The Service, including its software, design, text, graphics, trademarks and other content—excluding User Content—is owned by us or our licensors and is protected by applicable intellectual-property laws.

Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable and revocable right to use the Service for your own non-commercial purposes. No ownership rights are transferred to you.

10. Third-Party Services

The Service may depend on or link to third-party services, including app marketplaces, device platforms and integrations you choose to connect. Those services are governed by their own terms and privacy policies. We are not responsible for third-party services, but this does not limit responsibility we have under mandatory law for our own Service.

11. Availability, Maintenance and Updates

We aim to keep the Service secure and available, but uninterrupted operation cannot be guaranteed. Temporary interruptions may occur because of maintenance, updates, security incidents, network failures or events outside our reasonable control.

We will provide updates, including security updates, where required by applicable law. You are responsible for installing available updates and maintaining a compatible device and operating system after being appropriately informed of those requirements.

Your mandatory statutory rights concerning digital products remain unaffected.

12. Account Suspension, Termination and Deletion

You may stop using the Service at any time and may request account deletion using the functionality in the App or by contacting support@athlifuel.com. Cancelling a subscription and deleting an AthliFuel account are separate actions; deleting the account may not cancel marketplace billing, so you must also cancel the subscription through the relevant marketplace.

We may restrict or suspend access where reasonably necessary to investigate suspected fraud, unlawful use, security threats or a material violation of these Terms. We may terminate an account for a material or repeated violation. Where reasonable, we will give notice and an opportunity to correct the violation. Immediate action may be taken where necessary to protect users, the Service or third parties, or where the violation cannot be remedied.

Following termination or deletion, access to the account and User Content will end. Data will be deleted or retained in accordance with our Privacy Policy and applicable legal obligations. Mandatory consumer rights, accrued payment obligations and provisions intended to survive termination remain unaffected.

13. Changes to the Service

We may change the Service to maintain security or legal compliance, improve functionality, adapt to technical requirements or prevent misuse. Changes will not create additional charges without your agreement.

If a change materially and adversely affects your access to or use of a continuously provided digital service, we will inform you clearly and within the period required by law. Where applicable, you may terminate the affected contract free of charge within the statutory period. Mandatory rights under Sections 327 et seq. of the German Civil Code remain unaffected.

14. Changes to These Terms

We may update these Terms where reasonably necessary because of legal or regulatory changes, security needs, new or changed features, changes to our business model or clarification of existing wording. We will not use this provision to retroactively remove accrued rights or impose new payment obligations without your express agreement.

We will notify you in advance of material changes by an appropriate durable method, such as email or an in-app notice, and state when they take effect. If a material change negatively affects you, you may terminate the agreement before it takes effect. Changes made solely to benefit users, address urgent security risks or comply with mandatory law may take effect sooner where legally permitted.

15. Statutory Rights and Liability

15.1 Statutory rights

Nothing in these Terms excludes rights or remedies that cannot be excluded under applicable consumer law, including statutory rights relating to the provision, conformity, security and updating of digital products.

15.2 Liability

We are liable without limitation:

• For intent and gross negligence
• For injury to life, body or health caused by negligence
• Under the German Product Liability Act
• Where we have expressly given a guarantee or fraudulently concealed a defect

In cases of slight negligence, we are liable only for breach of an essential contractual obligation—an obligation whose performance is necessary for the proper performance of the agreement and on which you may regularly rely. In that case, liability is limited to the foreseeable damage typical for this type of agreement. Otherwise, liability for slight negligence is excluded to the extent permitted by law.

These limitations also apply for the benefit of our legal representatives and agents.

16. Governing Law

These Terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer habitually resident in another country, this choice does not deprive you of mandatory protections available under the law of that country.

The statutory rules on jurisdiction apply. Nothing in these Terms requires a consumer to bring a claim only before a court in Germany or Munich where mandatory law provides otherwise.

17. Consumer Dispute Resolution

We are neither obliged nor willing to participate in dispute-resolution proceedings before a consumer arbitration board, unless mandatory law requires otherwise.

18. General Provisions

If a provision of these Terms is wholly or partly invalid or unenforceable, the remaining provisions remain effective. The invalid provision is replaced only by the applicable statutory rule; this does not alter the interpretation of the remaining Terms.

A failure to enforce a provision on one occasion is not a waiver of the right to enforce it later. Headings are provided for readability and do not limit the meaning of a provision.

19. Contact and Provider Information

The legal operator, service address and other mandatory provider information are available in our Imprint.
