Terms and Conditions

Last updated: 2026-07-23

1. Introduction and Operator

These Terms and Conditions (the "Terms") govern your use of the Calpaca mobile application (the "App"), a calorie and nutrition tracking service for iOS and Android.

The App is operated by Michael Veltkamp, [ADDRESS], Germany (the "Operator", "we", "us"). You can reach us at [CONTACT EMAIL].

By creating an account or using the App, you enter into a contract with the Operator on the basis of these Terms.

2. Acceptance of These Terms

You accept these Terms by creating an account, or by continuing to use the App after having been given notice of them.

If you do not agree with these Terms, you must not use the App. Provisions of the Apple App Store and Google Play terms apply in addition where you obtained the App through those stores.

3. Eligibility

You must be at least 16 years old to use the App. This age limit reflects the age of digital consent applicable in Germany under the GDPR.

If you are younger than 16, you may only use the App if a holder of parental responsibility has given or authorised consent. We may suspend or delete accounts where we have reason to believe this requirement is not met.

4. The Service

Calpaca lets you log food, drinks and body weight, set nutrition goals, track progress, browse and generate recipes, and receive optional reminders and insights.

Certain features, including the AI coach chat, AI meal scanning and AI recipe generation, are premium features available under a paid subscription or during a free trial.

We may modify, add or remove features at any time, provided this does not unreasonably disadvantage you with respect to paid features you have already purchased.

5. Account and Security

You need an account to use the App. You can register with an email address and password, with Sign in with Apple, or with Google Sign-In.

You are responsible for keeping your login credentials confidential and for all activity that occurs under your account. Notify us at [CONTACT EMAIL] if you suspect unauthorised use of your account.

You must provide accurate information when registering and keep it up to date.

6. No Medical Advice

The App provides calorie and nutrition estimates for informational purposes only. It is not a medical device and does not provide medical, dietetic or therapeutic advice, diagnosis or treatment.

Calorie values, nutrient breakdowns, targets and AI-generated content are estimates and may be inaccurate or incomplete. Do not rely on them for medical decisions.

Consult a qualified healthcare professional before making significant changes to your diet or exercise, in particular if you are pregnant, have a medical condition, take medication, or have a history of disordered eating. If you are affected by or at risk of an eating disorder, please seek professional support before using a calorie tracking app.

7. Subscriptions, Free Trials and Payment

Premium features require an auto-renewing subscription purchased through the Apple App Store or Google Play. Prices, billing periods and any introductory offers are shown in the App before purchase.

Paid subscriptions may include a free trial of 7 or 14 days. Unless you cancel before the trial ends, the subscription converts to a paid subscription and the store charges the displayed price. Subscriptions renew automatically until cancelled.

You manage and cancel subscriptions in your App Store or Google Play account settings; deleting the App does not cancel a subscription. We may also grant an app-side free trial that does not require payment details and simply expires without charge.

Payments are processed by Apple or Google. Refunds are governed exclusively by the policies of the respective store; we do not issue refunds outside those policies except where required by mandatory law. Your statutory warranty rights remain unaffected.

8. AI Features

AI features such as coach chat, meal photo analysis and recipe generation use an artificial intelligence backend. Content you submit for these features (for example chat messages or food photos) is processed by our AI service provider as described in the Privacy Policy.

AI output is generated automatically and may be wrong, incomplete or unsuitable for your situation. You must review AI output critically and must not treat it as professional advice.

You must not submit unlawful content, content that infringes the rights of third parties, or personal data of other people to the AI features.

9. Acceptable Use

You may use the App only for your personal, non-commercial nutrition tracking and only in accordance with applicable law and these Terms.

You must not attempt to gain unauthorised access to our systems or data of other users, reverse engineer the App except as permitted by mandatory law, interfere with the operation of the App, misuse the AI features, scrape or bulk-export content, or resell or sublicense the service.

10. Your Content

You retain all rights to the content you enter into the App, such as food logs, notes, photos and chat messages ("User Content").

You grant us the non-exclusive right to store, process and display your User Content to the extent necessary to operate the App and provide its features to you, including processing by the service providers named in the Privacy Policy.

You are responsible for your User Content and warrant that it does not infringe the rights of third parties.

11. Intellectual Property

The App, its design, code, curated recipe catalog, texts, graphics and trademarks are owned by the Operator or its licensors and are protected by copyright and other intellectual property laws.

We grant you a limited, non-exclusive, non-transferable, revocable licence to use the App on devices you own or control for personal purposes. No other rights are granted.

12. Notifications

The App can send optional local reminder notifications, for example to log meals or weigh-ins. Notifications are off unless you enable them and can be disabled at any time in the App or in your device settings.

13. Liability

We are liable without limitation for damages caused by intent or gross negligence, for injury to life, body or health, under the German Product Liability Act, and to the extent we have assumed a guarantee.

In cases of slight negligence, we are liable only for the breach of essential contractual obligations (cardinal obligations), meaning obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely. In such cases our liability is limited to the foreseeable damage typical for this type of contract.

Any further liability is excluded. The above limitations also apply in favour of our legal representatives and vicarious agents. Liability for the accuracy of calorie or nutrition estimates and AI output is excluded to the extent permitted by law, as set out in Section 6.

14. Termination

You may terminate the user contract at any time by deleting your account in the App settings. Deleting your account permanently erases all data associated with it.

We may terminate the contract with reasonable notice, and may suspend or terminate your access without notice for good cause, in particular in the case of serious or repeated breaches of these Terms.

Termination does not automatically cancel a store subscription; cancel it in your App Store or Google Play account to avoid further charges.

15. Changes to These Terms

We may amend these Terms for valid reasons, for example changes in law, new features or changes to our services. We will notify you of material changes in the App or by email in advance.

If you do not agree to amended Terms, you may terminate the contract by deleting your account before the changes take effect. Continued use after the effective date constitutes acceptance where this is permissible under applicable law.

16. Governing Law, Miscellaneous and Contact

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, mandatory consumer protection provisions of the country of your habitual residence remain unaffected.

Should individual provisions of these Terms be invalid, the remaining provisions remain in effect. We are neither obliged nor willing to participate in dispute resolution proceedings before a consumer arbitration board (Section 36 VSBG).
