Esmarchstr. 5
40223 Düsseldorf, Germany
(hereinafter “Provider”)

and the user (hereinafter “Customer”) regarding the use of the Software-as-a-Service platform “flintery” (hereinafter “Service”).

(2) flintery is exclusively directed at entrepreneurs within the meaning of § 14 of the German Civil Code (BGB). An entrepreneur is a natural or legal person or a partnership with legal capacity that, when concluding a legal transaction, acts in the exercise of its commercial or independent professional activity. By registering, the Customer confirms that they use the Service exclusively for commercial or independent professional purposes.

(3) Deviating, conflicting or supplementary general terms and conditions of the Customer shall only become part of the contract if the Provider has expressly agreed to their validity in writing.

(2) The exact scope of features depends on the plan selected by the Customer (see § 5). The Provider reserves the right to expand and improve the scope of features, provided that the essential functions of the booked plan are retained.

(3) The Service is intended for calculation and planning. flintery does not generate invoices, offers or other business documents in the legal sense. Calculations and analyses created via the software — unless expressly stated otherwise — do not necessarily comply with the respective current tax or financial regulations and in no case replace individual tax advice. Calculation results can be exported as an Excel or CSV file and further processed in external accounting software.

(4) The Service is provided as Software-as-a-Service (SaaS). The Customer is granted a non-exclusive, non-transferable right to use the Service via a web browser. Installation on Customer devices is neither required nor intended.

(5) The Provider owes the provision of the platform but not any specific commercial success of the Customer. In particular, the calculation and benchmark features do not constitute legal, tax or business advice.


§ 3 Contract conclusion and registration

(1) The presentation of the Service on the website does not constitute a legally binding offer but rather an invitation to submit an offer (invitatio ad offerendum).

(2) By submitting the registration form, the Customer makes a binding offer to conclude a usage agreement. The contract is concluded when the Provider accepts the offer by activating the customer account or by express confirmation via email.

The Provider reserves the right to request specific evidence of entrepreneurial activity from the Customer in individual cases (e.g. trade registration, VAT ID).

(4) The Customer is obliged to keep their access credentials confidential and to protect them from third-party access. The Customer is liable for all activities carried out using their access credentials, except where they are not responsible for the unauthorised use.

(5) The Customer is obliged to inform the Provider without undue delay if they become aware that third parties are using their access credentials without authorisation.

(6) Each user account is intended exclusively for use by a single user. Shared use of a user account by multiple persons (“account sharing”) is not permitted. The Customer may purchase additional user accounts according to the selected plan as needed.

If the Customer does not object to the price change within 14 days of receiving the notification, the price change is deemed approved. The Provider will inform the Customer in the notification of the right to object and the consequences of remaining silent. In case of an objection, the Customer has the right to terminate the contract as of the date the price change takes effect.

(1) flintery offers a benchmark feature that provides anonymised market data on fees and project conditions.

All rights to the benchmark data — including the aggregated, anonymised and statistically processed data, comparative values, analyses and any insights derived therefrom — remain exclusively with the Provider. The benchmark data also constitutes a trade secret of the Provider within the meaning of the German Trade Secrets Act (Geschäftsgeheimnisgesetz, GeschGehG).

(4) Liability for slightly negligent breach of non-material contractual obligations is excluded.

(5) Liability under the German Product Liability Act (Produkthaftungsgesetz) remains unaffected.

The Customer remains the controller under data protection law for this data.

(4) Upon request, the Provider will conclude a data processing agreement (DPA) with the Customer pursuant to Art. 28 GDPR.

The requested contracting party is obliged to grant consent to release from the confidentiality obligation if, weighing all circumstances of the individual case, the requested contracting party's particular legitimate interests do not outweigh the requesting contracting party's interests, and the requesting contracting party would suffer disproportionate disadvantages from a refusal to consent.

(2) Valid reasons for an amendment include in particular:
