Terms of Service
Effective: 2 July 2026
These Terms of Service ("Terms") govern the use of the Nahria app and related services (the "Service"), including the "Nahria Pro" subscription. This English version is provided for convenience only; the German version (AGB) is authoritative.
The Service is provided by Johann Christian Gebhardt, Ludwig-Wucherer-Straße 27, 06108 Halle (Saale), Germany, email: contact@nahria.app ("we", "us").
1. The Service
Nahria is an app for tracking calories and nutrition. The core features (manual meal logging, goals, insights) are free. In addition, the app offers AI-assisted nutrition estimation from text or photos: a limited number of such estimates is free; beyond that, AI estimation requires an active Nahria Pro subscription. "Unlimited" AI estimates under the subscription are available for normal personal use; we may apply technical safeguards against automated or abusively excessive use.
Nutrition values and AI estimates are approximations. They may be inaccurate or incomplete, and we do not guarantee their correctness. Always verify important information — for example regarding allergies or intolerances — against the manufacturer's labeling.
2. No medical advice
Nahria is for informational and record-keeping purposes only and is not a medical device. The app is no substitute for medical or nutritional advice, diagnosis, or treatment. If you have health issues, are pregnant, suffer from an eating disorder, or must follow a specific diet for medical reasons, talk to a doctor before using the app.
3. Account and eligibility
Using the Service requires an account with a valid email address. You must be at least 16 years old; minors need the consent of a parent or guardian. Protect access to the email inbox used for sign-in; actions taken through your account are attributed to you to the extent you are responsible for them.
4. Nahria Pro: purchase, prices and payment
The Nahria Pro subscription (monthly or yearly) is purchased as an in-app purchase through the Apple App Store or Google Play. The purchase is concluded under the respective store's terms; payment processing, invoicing, and any refunds are handled by the respective store. The applicable prices (including VAT) are shown to you in the store before purchase.
5. Term, renewal and cancellation
The subscription renews automatically for the respective term unless cancelled at least 24 hours before the end of the current billing period. Cancellation is done exclusively through the subscription settings of your Apple or Google account. Deleting the app or your Nahria account does not end an active subscription — cancel it in the store as well.
6. Right of withdrawal
Consumers generally have a statutory 14-day right of withdrawal for distance contracts. For purchases made through the Apple App Store or Google Play, direct withdrawal and refund requests to the respective store through which the purchase was processed; they provide corresponding refund procedures. Your statutory rights remain unaffected.
Where a contract for digital content or digital services is concluded directly with us, the following applies: you may withdraw your contractual declaration within 14 days without giving reasons, in text form (e.g. by email to contact@nahria.app). For digital content, the right of withdrawal expires if we have begun performance after you expressly consented to us beginning before the withdrawal period ends and you confirmed that you thereby lose your right of withdrawal (Section 356(5) of the German Civil Code, BGB).
7. Promo and referral codes
We may issue promo or referral codes granting, for example, discounts or additional free AI estimates. Codes are non-transferable, have no cash value, and may be subject to conditions (such as validity periods or new-customer restrictions) stated with the respective code. In case of abuse — such as mass self-referral or automated redemption — we may block codes and revoke benefits granted through them.
8. Acceptable use
You receive a simple, non-transferable right to use the app for your own personal purposes. The following are not permitted in particular: circumventing technical restrictions (such as the AI quota), automated access to the Service, submitting unlawful content, and any use that impairs the Service or other users.
9. Availability and changes to the Service
We strive for high availability of the Service but do not owe uninterrupted availability; maintenance and outages (including at third-party providers, such as the AI services) may temporarily limit the Service. We continuously develop the app and may change features to the extent reasonable for you. Your statutory rights regarding changes to digital products (Sections 327 et seq. BGB) remain unaffected.
10. Warranty and liability
The statutory warranty rights for digital products (Sections 327 et seq. BGB) apply.
We are liable without limitation for intent and gross negligence, for injury to life, body, or health, and under the German Product Liability Act. In cases of slight negligence, we are liable only for the breach of essential contractual obligations (obligations whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance you may regularly rely), limited to the foreseeable damage typical for this type of contract. Any further liability is excluded.
11. Privacy
Information about the processing of personal data can be found in our Privacy Policy.
12. Consumer dispute resolution
We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board (Section 36 of the German Consumer Dispute Resolution Act, VSBG).
13. Final provisions
German law applies. 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 validity of the remaining provisions remains unaffected.
The German version of these Terms is authoritative; this English version is provided for information only.
