If you do not agree to these Terms, you may not access or use the Service. Please read these Terms carefully before using N+One.

1. Acceptance of Terms
By creating an account or using N+One, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy. If you are using the Service on behalf of an organization, you agree to these Terms on behalf of that organization.
We may propose changes to these Terms. Before a material change is meant to apply, we will tell you by email or in the Service what changes and when.
For consumers, continued use is not by itself acceptance of a material change. These Terms are standard terms (Allgemeine Geschäftsbedingungen). A change becomes part of the contract only if you agree to it. If we ever treat silence or continued use as agreement, we will do so only by giving you a reasonable period to make an express statement, and at the start of that period we will specifically tell you what silence or continued use will mean. You may cancel under section 7.3 before a material change applies. That cancellation does not affect the statutory withdrawal right in section 7.
Wir können Änderungen dieser Bedingungen vorschlagen. Bevor eine wesentliche Änderung gelten soll, informieren wir Sie per E-Mail oder im Dienst darüber, was sich wann ändert.
Gegenüber Verbraucherinnen und Verbrauchern ist die weitere Nutzung für sich genommen keine Zustimmung zu einer wesentlichen Änderung. Diese Bedingungen sind Allgemeine Geschäftsbedingungen. Eine Änderung wird nur Vertragsbestandteil, wenn Sie mit ihrer Geltung einverstanden sind. Eine Regelung, nach der Schweigen oder Weiternutzung als Zustimmung gilt, verwenden wir nur so, dass wir Ihnen eine angemessene Frist zur ausdrücklichen Erklärung einräumen und Sie bei Beginn der Frist besonders auf die Bedeutung Ihres Verhaltens hinweisen. Sie können nach Ziffer 7.3 kündigen, bevor eine wesentliche Änderung gilt. Das berührt nicht das gesetzliche Widerrufsrecht in Ziffer 7.
2. Account Registration and Security
2.1 Account Creation
To use certain features of the Service, you must create an account. You agree to provide accurate, current, and complete information during registration and to update such information to keep it accurate, current, and complete.
You must be at least 16 years old to create an account and use the Service.
2.2 Account Security
You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You agree to notify us immediately of any unauthorized access or use of your account.
We reserve the right to suspend or terminate your account if we suspect any unauthorized or fraudulent activity.
3. Use of the Service
3.1 License Grant
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal, non-commercial use.
3.2 Acceptable Use
You agree not to use the Service to:
- Violate any applicable laws, regulations, or third-party rights
- Upload, transmit, or distribute any malicious code, viruses, or harmful content
- Interfere with or disrupt the Service or servers or networks connected to the Service
- Attempt to gain unauthorized access to any part of the Service
- Use automated means to access the Service without our express written permission
- Impersonate any person or entity or misrepresent your affiliation with any person or entity
- Collect or harvest any information from the Service or other users
4. Third-Party Integrations
N+One integrates with third-party services (such as Garmin, Strava, Wahoo, and WHOOP) to import and analyze your training data. By connecting these integrations:
- You authorize us to access and process data from these services as described in our Privacy Policy
- You acknowledge that your use of third-party services is governed by their respective terms of service and privacy policies
- We are not responsible for the availability, functionality, or content of third-party services
- You can disconnect integrations at any time through your account settings
5. User Content and Data
5.1 Your Content
You retain all rights to your training data, health data, and other content you upload or sync to the Service ("User Content"). Where User Content includes health-related or other special-category data, or where we use it for AI coaching, we process that data only with your explicit consent under GDPR Art. 9(2)(a) as described in Privacy Policy §3 and via our in-app consent gateway — not merely because these Terms form a contract. Subject to that consent (where required), you grant us a worldwide, non-exclusive license to use, store, process, and display your User Content solely for the purpose of providing and improving the Service.
5.2 Data Usage and Privacy
We collect and process your personal data as described in our Privacy Policy. Contract performance under these Terms does not by itself authorize health-data sync or AI coaching that uses special-category data; those purposes require explicit consent (Privacy Policy §3; Settings → Privacy). We use aggregated, anonymized data to improve our algorithms and services where no Art. 9 data is required.
You have the right to export or delete your data at any time through your account settings or by contacting us.
6. AI-Generated Content and Recommendations
N+One uses artificial intelligence to provide training recommendations, insights, and coaching advice. You acknowledge that:
- AI-generated recommendations are for informational purposes only and should not be considered professional medical or coaching advice
- You should consult with qualified healthcare or coaching professionals before making significant changes to your training regimen
- We do not guarantee the accuracy, completeness, or suitability of AI-generated content for your specific needs
- You use AI-generated recommendations at your own risk
7. Subscriptions and Payments
7.1 Subscription Plans
N+One offers various subscription plans with different features and pricing. Subscription fees are billed in advance on a recurring basis (monthly, annually, or as otherwise specified).
7.2 Billing and Renewal
By subscribing, you authorize us to charge your payment method for the applicable fees. Your subscription will automatically renew at the end of each billing period unless you cancel before the renewal date.
7.3 Cancellation and Refunds
You may cancel your subscription at any time through your account settings. Cancellations take effect at the end of the current billing period, and you will continue to have access to paid features until then.
Ordinary cancellation under this section 7.3 is not withdrawal. It takes effect at the end of the current billing period. We do not refund the unused part of a period that has already started, unless a mandatory statute requires a refund or we refund as a goodwill gesture.
This does not limit the statutory right of withdrawal in the German text below. If you withdraw in time, refunds follow that text: the same means of payment, within fourteen days after we receive your notice, with no fee for the refund. End-of-period cancellation and statutory withdrawal are different rights.
Die ordentliche Kündigung nach dieser Ziffer 7.3 ist nicht der Widerruf. Sie wirkt zum Ende des laufenden Abrechnungszeitraums. Ein anteiliges Entgelt für einen bereits begonnenen Zeitraum erstatten wir nicht, es sei denn, ein zwingendes Gesetz verlangt die Erstattung oder wir erstatten freiwillig aus Kulanz.
Dieser Satz schränkt das gesetzliche Widerrufsrecht im deutschen Text unten nicht ein. Bei einem fristgerechten Widerruf richtet sich die Rückzahlung nach diesem Text: dasselbe Zahlungsmittel, binnen vierzehn Tagen nach Eingang Ihrer Erklärung, ohne Entgelt für die Rückzahlung. Kündigung zum Periodenende und gesetzlicher Widerruf sind verschiedene Rechte.
7.4 Widerrufsbelehrung
Widerrufsrecht
Sie haben das Recht, binnen vierzehn Tagen ohne Angabe von Gründen diesen Vertrag zu widerrufen.
Die Widerrufsfrist beträgt vierzehn Tage ab dem Tag des Vertragsabschlusses.
Um Ihr Widerrufsrecht auszuüben, müssen Sie uns (N+One UG (haftungsbeschränkt) i.G., Dürener Straße 341, 50935 Köln, Germany, E-Mail: hi@nplusone.app) mittels einer eindeutigen Erklärung (z. B. ein mit der Post versandter Brief oder eine E-Mail) über Ihren Entschluss, diesen Vertrag zu widerrufen, informieren. Sie können dafür das beigefügte Muster-Widerrufsformular verwenden, das jedoch nicht vorgeschrieben ist.
Zur Wahrung der Widerrufsfrist reicht es aus, dass Sie die Mitteilung über die Ausübung des Widerrufsrechts vor Ablauf der Widerrufsfrist absenden.
Folgen des Widerrufs
Wenn Sie diesen Vertrag widerrufen, haben wir Ihnen alle Zahlungen, die wir von Ihnen erhalten haben, unverzüglich und spätestens binnen vierzehn Tagen ab dem Tag zurückzuzahlen, an dem die Mitteilung über Ihren Widerruf dieses Vertrags bei uns eingegangen ist. Für diese Rückzahlung verwenden wir dasselbe Zahlungsmittel, das Sie bei der ursprünglichen Transaktion eingesetzt haben, es sei denn, mit Ihnen wurde ausdrücklich etwas anderes vereinbart; in keinem Fall werden Ihnen wegen dieser Rückzahlung Entgelte berechnet.
Haben Sie verlangt, dass die Dienstleistungen während der Widerrufsfrist beginnen soll, so haben Sie uns einen angemessenen Betrag zu zahlen, der dem Anteil der bis zu dem Zeitpunkt, zu dem Sie uns von der Ausübung des Widerrufsrechts hinsichtlich dieses Vertrags unterrichten, bereits erbrachten Dienstleistungen im Vergleich zum Gesamtumfang der im Vertrag vorgesehenen Dienstleistungen entspricht.

Convenience EN summary (non-statutory)
Consumers in the EU/EEA generally have 14 days from contract conclusion to withdraw a distance Pro subscription without giving reasons, by clear statement to hi@nplusone.app (model form above). Refunds follow the German statutory rules summarized in the German text. Early performance may affect the right of withdrawal if the statutory acknowledgements were given at checkout.
A free Pro trial, where offered, does not replace your statutory right of withdrawal under German law.
8. Intellectual Property
The Service, including its software, algorithms, design, trademarks, and content (excluding User Content), is owned by N+One and protected by copyright, trademark, and other intellectual property laws.
You may not copy, modify, distribute, sell, or reverse engineer any part of the Service without our express written permission.
9. Disclaimer of Warranties
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.
We do not warrant that:
- The Service will be uninterrupted, secure, or error-free
- The results obtained from the Service will be accurate or reliable
- Any errors or defects in the Service will be corrected
Section 10 states where the limits in section 9 and section 10 do not apply.
Ziffer 10 sagt, wo die Grenzen in Ziffer 9 und Ziffer 10 nicht gelten.
10. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NPLUSONE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR USE, ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR THE SERVICE.
IN NO EVENT SHALL OUR TOTAL LIABILITY TO YOU EXCEED THE AMOUNT YOU PAID US IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR €100, WHICHEVER IS GREATER.
Nothing in section 9 or section 10 excludes or limits liability where that exclusion or limitation is ineffective, in particular:
- liability for injury to life, body, or health based on a negligent breach by us or on an intentional or negligent breach by a legal representative or vicarious agent (§ 309 No. 7(a) BGB);
- liability for other damage based on gross negligence by us or on intent or gross negligence by a legal representative or vicarious agent (§ 309 No. 7(b) BGB);
- liability under the Product Liability Act, which may not be excluded or limited in advance (§ 14 ProdHaftG).
The section 10 cap otherwise remains a standard-term limitation and applies only so far as § 307 BGB allows. Sections 9 and 10 do not limit the statutory withdrawal refunds in section 7.
Ziffer 9 und Ziffer 10 schließen eine Haftung nicht aus und begrenzen sie nicht, soweit ein solcher Ausschluss oder eine solche Begrenzung unwirksam ist, insbesondere nicht
- die Haftung für Schäden aus der Verletzung des Lebens, des Körpers oder der Gesundheit, die auf einer fahrlässigen Pflichtverletzung von uns oder einer vorsätzlichen oder fahrlässigen Pflichtverletzung eines gesetzlichen Vertreters oder Erfüllungsgehilfen beruhen (§ 309 Nr. 7 Buchstabe a BGB);
- die Haftung für sonstige Schäden, die auf einer grob fahrlässigen Pflichtverletzung von uns oder auf einer vorsätzlichen oder grob fahrlässigen Pflichtverletzung eines gesetzlichen Vertreters oder Erfüllungsgehilfen beruhen (§ 309 Nr. 7 Buchstabe b BGB);
- die Haftung nach dem Produkthaftungsgesetz; diese Ersatzpflicht darf im Voraus weder ausgeschlossen noch beschränkt werden (§ 14 ProdHaftG).
Die Haftungsobergrenze in Ziffer 10 bleibt im Übrigen eine AGB-Regelung und gilt nur, soweit § 307 BGB das zulässt. Ziffer 9 und 10 schränken die gesetzlichen Widerrufs-Rückzahlungen in Ziffer 7 nicht ein.
11. Indemnification
You agree to indemnify, defend, and hold harmless N+One and its officers, directors, employees, and agents from any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or in connection with your use of the Service, your User Content, or your violation of these Terms.
12. Termination
You may terminate your account at any time by contacting us or through your account settings. Upon termination, your right to use the Service will immediately cease.
We may suspend or terminate your account or access to the Service at any time, with or without cause, and with or without notice, if we believe you have violated these Terms or for any other reason.
Upon termination, we may delete your User Content and account data, subject to our data retention policies and applicable law.
13. Governing Law and Dispute Resolution
These Terms shall be governed by and construed in accordance with the laws of Germany, without regard to its conflict of law provisions.
Any disputes arising out of or relating to these Terms or the Service shall be resolved in the courts of Germany.
14. General Provisions
14.1 Entire Agreement
These Terms, together with our Privacy Policy, constitute the entire agreement between you and N+One regarding the Service and supersede all prior agreements and understandings.
14.2 Severability
If any provision of these Terms is found to be invalid or unenforceable, the remaining provisions shall remain in full force and effect.
14.3 Waiver
Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision.
14.4 Assignment
You may not assign or transfer these Terms or your rights under these Terms without our prior written consent. We may assign these Terms without restriction.
