Version 4.1 – December 2025
§ 1 Preamble and Scope
SELLRZ.io is an AI-powered SaaS platform operated by SELLRZ GmbH (i.Gr.) (the "Provider"), supporting Amazon sellers in the analysis, optimization and management of their product listings and advertising campaigns.
These Terms and Conditions apply to all contracts between the Provider and the user (the "Customer"). SELLRZ.io is directed exclusively at businesses within the meaning of § 14 of the German Civil Code (BGB). Use by consumers (§ 13 BGB) is excluded.
Deviating terms of the Customer shall not become part of the contract unless the Provider expressly agrees to them in text form.
§ 2 Subject of the Contract
The Provider makes available to the Customer a cloud-based software platform accessible via web browser login.
The platform serves as an assistance system – it supports the Customer but does not replace the Customer's own business decisions.
The Provider does not guarantee any specific economic success, revenue increase or improvement of Amazon rankings.
The Provider reserves the right to further develop the platform, adapt features or add new features, provided the core functionality of the chosen plan is maintained.
§ 3 Services and Third-Party Providers
3.1 Platform Services
The Provider makes the platform available with the following core functions:
- Listing analysis and optimization
- Keyword research
- Advertising management (PPC)
- AI-supported text and image generation
The exact scope of functions depends on the chosen plan.
3.2 Amazon SP-API
The platform accesses Customer data via the Amazon Selling Partner API (SP-API). The Customer authorizes this through the Amazon OAuth process and may revoke authorization at any time.
3.3 AI Third-Party Providers
To provide AI functions, the platform uses external providers, in particular:
- OpenAI
- Google (Gemini)
- Anthropic (Claude)
The Provider may add or replace AI providers provided that an equivalent level of service is maintained.
3.4 Third-Party Dependence
The platform's functionality depends on Amazon and the aforementioned AI providers.
The Provider is not liable for outages, changes or limitations of these third-party services.
Such events do not constitute a defect and do not give rise to any claim for price reduction, damages or free extension.
3.5 AI Notice
AI-generated content may be incorrect or unsuitable. The Customer is obliged to review all output independently.
§ 4 Registration and User Account
The contract is formed when the Customer completes the registration form, accepts these Terms and Conditions, and the Provider activates access.
The Customer is responsible for keeping login credentials confidential.
Sharing of accounts is not permitted.
Abusive use is prohibited, in particular:
- Reverse engineering
- Automated bulk requests
- Violations of Amazon policies
§ 5 Pricing and Payment
Fees are determined by the selected subscription.
All prices are net amounts plus applicable value added tax.
Payments are due in advance.
In case of late payment, the Provider is entitled to block access after reminder.
There is no automatic right to a refund. Discretionary refunds are at the Provider's sole discretion.
§ 6 Availability and Liability
6.1 Availability
The platform is provided "as available". No specific availability is guaranteed unless a separate SLA has been agreed.
6.2 Unlimited Liability
The Provider has unlimited liability in cases of intent, gross negligence, and for damage to life, body or health.
6.3 Limited Liability
In cases of simple negligence, the Provider is liable only for breach of essential contractual obligations, limited to foreseeable damage.
Liability is capped at three times the fees paid in the last 12 months, but no more than 50,000 EUR.
6.4 Exclusions of Liability
No liability applies in particular for:
- Outages of the Amazon SP-API
- Outages of external AI providers
- Changes to external interfaces
- Use of AI-generated content without review
§ 7 Term and Termination
7.1 Contract Term
The contract is concluded for the term selected at the time of booking. Depending on the agreement, the minimum term is:
- 1 month
- 3 months
- 6 months
- 12 months
The specific term is determined by the chosen plan or offer.
7.2 Renewal
The contract automatically renews for the originally selected term unless terminated in due time.
7.3 Notice Periods
Termination must be made in text form.
- 14 days before end of term for 1–6 month terms
- 30 days before end of term for 12 month terms
7.4 Extraordinary Termination
The right to extraordinary termination for good cause remains unaffected.
7.5 Effects of Contract End
Access to the platform ends when the contract ends.
Data export is provided on request. Thereafter, data is deleted unless statutory retention obligations apply.
§ 8 Rights in Content and Data
All rights in the platform remain with the Provider.
Customer data remains the property of the Customer.
AI-generated content is made available to the Customer for use. The Provider does not warrant that such content is free of third-party rights.
§ 9 Data Protection and Security
The Provider processes personal data only in accordance with applicable law, in particular the GDPR.
Only data necessary for registration and use are processed (e.g. name, email address, payment data, technical access data).
The Provider does not process personal data of the Customer's end customers in the sense of processing on behalf under Art. 28 GDPR. A data processing agreement (DPA) is therefore not part of this contractual relationship.
The Provider implements appropriate technical and organizational measures in accordance with Art. 32 GDPR. These include in particular:
- Encrypted data transmission (TLS/HTTPS)
- Encrypted storage of sensitive data
- Access restrictions
- Regular security updates
Communication is encrypted.
Further information can be found in the privacy policy.
§ 10 Amendments to the Terms
The Provider may amend these Terms and Conditions with 30 days' notice.
If the Customer does not object within 30 days, the amendments are deemed accepted.
§ 11 Final Provisions
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods.
Place of jurisdiction is Hamburg, where permitted by law.
If any provision is invalid, the remainder of the contract remains in effect.
