Terms of Service

Last updated: 2026-08-27

These Terms of Service (the "Terms") govern the provision of the Services by Causa Prima Germany GmbH, registered with the commercial register of the Local Court (Amtsgericht) of Berlin-Charlottenburg under HRB 286382 B, with registered seat in Berlin ("Causa Prima"), to the customer that accepts these Terms (the "Customer"). Each a "Party" and together the "Parties".

The Customer accepts these Terms in one of two ways, with the same effect:

• Electronically at signup — by checking the "I agree" box presented at signup on app.causaprima.ai, which links to these Terms and the Data Processing Agreement; or
• By order form — by executing an order form or other written agreement with Causa Prima that incorporates these Terms by reference.

The Data Processing Agreement available at app.causaprima.ai/dpa (Annex 1, the "DPA") is incorporated into these Terms by reference and forms an integral part of them. A single acceptance of these Terms — by either method above — also constitutes acceptance of the DPA.

The "Services" are the products and services Causa Prima makes available to the Customer under the Customer's account at app.causaprima.ai, together with any related interfaces Causa Prima provides, as further described in the applicable order form where one exists.

The Services are provided to businesses only. By accepting these Terms, the Customer confirms that it acts as an entrepreneur (Unternehmer within the meaning of § 14 BGB) and not as a consumer.

1. Services

1.1 Causa Prima grants the Customer a non-exclusive, non-transferable, non-sublicensable right, for the term of these Terms, to access and use the Services for the Customer's internal business purposes and in accordance with the documentation and reasonable use instructions made available by Causa Prima.

1.2 The Customer may authorise employees and contractors acting on its behalf to use the Services ("Users"). The Customer is responsible for its Users' compliance with these Terms, keeps its access credentials confidential and is responsible for activities carried out through its account.

1.3 The Customer will not (a) reverse-engineer, decompile or attempt to derive the source code of the Services, except to the extent such restriction is prohibited by law, (b) resell, sublicense or make the Services available to any third party, (c) use the Services to build a competing product, (d) circumvent usage limits or access controls, (e) use the Services in violation of applicable law or third-party rights, (f) submit special categories of personal data (Article 9 GDPR) to the Services, (g) gain or attempt to gain unauthorised access to the Services, their systems or other customers' data, (h) scrape, overload or otherwise impair the operation or integrity of the Services, or (i) submit content that is unlawful, harmful, infringing, deceptive or misleading.

1.4 Suspension. Causa Prima may suspend the Customer's or a User's access to the Services, in whole or in part, where reasonably necessary to (a) address a material security risk or an ongoing breach of § 1.3, (b) comply with a legal requirement or binding order, or (c) prevent material harm to the Services or to other customers. Causa Prima will limit any suspension to what is necessary, give the Customer notice where practicable (and otherwise without undue delay afterwards), and restore access promptly once the cause is resolved. Suspension for non-payment is governed by § 3.3.

2. Term and termination

2.1 These Terms take effect when the Customer first accepts them (the "Effective Date") and continue in force until terminated in accordance with this § 2.

2.2 Either Party may terminate these Terms at any time for convenience with effect from the end of the then-current billing period or, where no billing period applies, on thirty (30) days' notice in text form.

2.3 Either Party may terminate these Terms for cause with immediate effect by notice in text form if the other Party materially breaches these Terms and fails to cure the breach within thirty (30) days of a notice describing the breach; a cure period is not required where it would be unreasonable under § 314(2) BGB.

2.4 Either Party may terminate these Terms for cause with immediate effect if insolvency proceedings are opened over the other Party's assets or their opening is refused for lack of assets, to the extent such termination is permitted by law.

2.5 On termination or expiry of these Terms:

• (a) the Customer's right to access the Services ends;
• (b) the Customer remains liable for any fees accrued before termination;
• (c) during the thirty (30) days after termination, Causa Prima will, on the Customer's request, make Customer Content available for export in a commonly used format;
• (d) where the Customer has chosen return under clause 13.1 of the DPA, the export under (c) satisfies that choice; after that 30-day period, Causa Prima deletes Customer Data (including all Customer Content), as defined in the DPA, in accordance with the DPA and Causa Prima's data retention schedule, except for data Causa Prima is required by law to retain (in particular accounting records and invoices under § 257 HGB and § 147 AO), which is deleted when the statutory retention period ends; and
• (e) provisions that by their nature survive termination remain in effect (including § 4, § 5, § 6, § 7, § 9, § 10 and § 12).

3. Fees, invoicing and taxes

3.1 Fees, the billing period and payment terms are set out in the applicable order form or on the Service's pricing page. Where no fees are agreed, the Services are provided free of charge.

3.2 All amounts are exclusive of VAT and other applicable taxes, which are added at the rate in force on the date of supply. If the Customer is required to withhold taxes, the Customer will pay the additional amount necessary so that Causa Prima receives the net amount it would have received absent the withholding.

3.3 Undisputed overdue amounts bear default interest at the statutory rate (§ 288 BGB). Causa Prima may suspend the Services if undisputed fees remain unpaid after a reminder in text form, without prejudice to other remedies.

4. Customer Content; AI

4.1 "Customer Content" means the data, documents and other content that the Customer or its Users submit to the Services or authorise Causa Prima to receive through the Services. As between the Parties, the Customer owns and retains all rights, title and interest in and to Customer Content.

4.2 The Customer grants Causa Prima a non-exclusive, royalty-free, worldwide licence to host, process and use Customer Content solely to (a) provide, operate and secure the Services, and (b) improve the Services and develop, improve and train Causa Prima's AI and machine-learning models and related technology, in the case of (b) using outside the Customer's instance only Anonymised Data as defined and governed by the DPA — which requires anonymisation before Customer Content crosses the Customer's boundary and preserves the restrictions of connected source platforms, including the absolute exclusion of data received via Google Workspace APIs. Causa Prima acquires no other rights in Customer Content.

4.3 Whether and to what extent Customer Content may be used in connection with the training of AI models is governed by the DPA and described in Causa Prima's Privacy Policy.

4.4 AI output disclaimer. The Services include AI features. AI outputs are probabilistic and may be inaccurate, incomplete or unsuitable for a given purpose. AI outputs are provided for informational purposes only and do not constitute legal, tax, accounting, investment or other professional advice. The Customer will keep a meaningful human in the loop before relying on AI outputs for material decisions, financial reporting or any communication to third parties, and is responsible for reviewing and verifying AI outputs before use. The Services are not designed to take decisions that produce legal effects concerning, or similarly significantly affect, any individual without human involvement within the meaning of Article 22 GDPR.

4.5 The Customer is responsible for the accuracy and lawfulness of the Customer Content it submits and for complying with its own statutory record-keeping, retention and invoicing obligations (including, where applicable, under the German Commercial Code (HGB), the Fiscal Code (AO) and the VAT Act (UStG)).

5. Confidentiality

5.1 Each Party may disclose to the other non-public information that is marked as confidential or that a reasonable recipient would understand to be confidential ("Confidential Information"). The recipient will (a) use the discloser's Confidential Information only to perform these Terms, (b) protect it with at least the same degree of care it uses for its own confidential information of similar importance (and in any event no less than reasonable care), and (c) not disclose it to any third party except to personnel and advisors who need to know and are bound by equivalent obligations.

5.2 Confidential Information does not include information that is or becomes public without breach of these Terms, was rightfully known to the recipient without confidentiality obligations before disclosure, is independently developed without use of the discloser's Confidential Information, or is rightfully obtained from a third party without confidentiality obligations.

5.3 Confidentiality obligations survive termination of these Terms for as long as the Confidential Information remains non-public. Trade secrets remain protected for as long as they qualify as such under applicable law. Personal data is protected for as long as required under the DPA and applicable data-protection law.

5.4 Causa Prima may name the Customer in customer lists and on its website, subject to the Customer's prior approval in text form of the specific wording and logo use, not to be unreasonably withheld.

6. Intellectual property

6.1 As between the Parties, Causa Prima owns and retains all rights, title and interest in and to the Services, the underlying software, models, documentation and all related intellectual property, including any improvements, modifications and derivatives, regardless of whether based on Customer feedback.

6.2 The Customer may provide suggestions, recommendations and other feedback to Causa Prima ("Feedback"). The Customer grants Causa Prima a perpetual, irrevocable, worldwide, royalty-free, sublicensable licence to use, reproduce, modify and incorporate Feedback into the Services and Causa Prima's other products and offerings, without obligation of attribution or compensation.

6.3 The Customer retains all rights in and to Customer Content, subject to the licence granted in § 4.2.

7. Data protection

7.1 The processing of personal data contained in Customer Content on the Customer's behalf is governed by the DPA (Annex 1), including the Technical and Organisational Measures and the sub-processor list referenced in it. How Causa Prima processes personal data as a controller (for example, account, contact and billing data) is described in its Privacy Policy.

8. Security and availability

8.1 Causa Prima will operate the Services in accordance with the Technical and Organisational Measures referenced in § 7.

8.2 Causa Prima will use commercially reasonable efforts to make the Services available. Causa Prima does not commit to a specific availability level, and no service credits or contractual SLA remedies apply.

8.3 Causa Prima provides the Services from the interface between its hosting infrastructure and the internet. The Customer is responsible for its own internet connection and for the hardware and software required to access the Services.

9. Warranties; disclaimers

9.1 Causa Prima warrants that the Services will perform substantially in accordance with the documentation made available to the Customer. The Customer's exclusive remedy for breach of this warranty is, at Causa Prima's option, (a) re-performance, (b) correction of the non-conformity, or (c) termination of the affected portion of the Services with a pro-rata refund of pre-paid unused fees.

9.2 To the maximum extent permitted by applicable law, and except as expressly set out in these Terms, the Services are provided "as is" and "as available", without warranties of any kind, whether express, implied or statutory, including warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted or error-free operation.

9.3 Where the Services are provided for a fee, the statutory rules on the provision of items for use for a limited time (lease, §§ 535 et seq. BGB) apply to defect liability, except as otherwise set out in these Terms. The strict, fault-independent liability for defects existing at the start of the contract under § 536a(1), first alternative, BGB is excluded.

10. Limitation of liability

10.1 Causa Prima is liable without limitation for damage caused by intent (Vorsatz) or gross negligence (grobe Fahrlässigkeit), for injury to life, body or health, for liability under the German Product Liability Act (Produkthaftungsgesetz), and in the case of fraudulent concealment of a defect (arglistiges Verschweigen).

10.2 In cases of slight negligence (einfache Fahrlässigkeit), Causa Prima is liable only for the breach of a material contractual duty (Kardinalpflicht) — an obligation whose fulfilment makes the proper performance of these Terms possible in the first place and on whose fulfilment the Customer regularly relies — and such liability is limited to the damage that is typical for this type of contract and was foreseeable at the time these Terms were concluded.

10.3 Except as set out in § 10.1 and § 10.2, Causa Prima's liability for slight negligence is excluded.

10.4 The limitations in this § 10 also apply in favour of Causa Prima's legal representatives, employees and agents (Erfüllungsgehilfen).

10.5 Where the Services are provided to the Customer free of charge, Causa Prima is liable only for damage caused by intent or gross negligence; the mandatory liability under § 10.1 remains unaffected.

10.6 Where Causa Prima is liable for loss of data under this § 10, its liability is limited to the typical effort required to restore the data from copies the Customer could reasonably have been expected to retain of the content it submitted to the Services.

11. Force majeure

11.1 Neither Party is liable for failure or delay in performance (other than payment obligations) caused by circumstances beyond its reasonable control, including acts of God, war, terrorism, civil unrest, government action, labour disputes, internet or telecommunications failures, or pandemic. The affected Party will notify the other promptly and use reasonable efforts to mitigate. If the event persists for a substantial, non-transitory period, either Party may terminate the affected Services under § 2.2.

12. General

12.1 Entire agreement; precedence. These Terms, the DPA and any order form incorporating them together constitute the entire agreement between the Parties on their subject matter and supersede all prior discussions and agreements on that subject matter. In case of conflict, an order form prevails over these Terms on the commercial terms it addresses, and the DPA prevails on matters relating to the processing of personal data.

12.2 Amendments; changes to these Terms. Negotiated amendments to these Terms must be made in text form (§ 126b BGB) and confirmed by both Parties. In addition, Causa Prima may update these standard Terms with effect for the future on objective grounds — in particular changes in applicable law or regulation, court or authority decisions, new or modified features, or security or operational requirements — provided the update does not materially shift the balance of these Terms to the Customer's disadvantage. Causa Prima will notify the Customer of any such update in text form at least thirty (30) days before it takes effect; the change notice will state expressly that if the Customer does not object within the notice period and continues to use the Services, this will be treated as acceptance of the updated Terms. The Customer may object in text form before the update takes effect; if the Customer objects, the prior version continues to apply and either Party may terminate under § 2.2. If the Customer does not object and continues to use the Services after the update takes effect, the updated Terms apply. Causa Prima retains a record of the version of these Terms the Customer accepted.

12.3 Notices. Notices under these Terms must be in text form (§ 126b BGB) and sent to the addresses the Parties have notified each other of in text form; e-mail is sufficient.

12.4 Assignment. Neither Party may assign these Terms without the other's prior consent in text form, except that either Party may assign to an affiliate or in connection with a merger, reorganisation or sale of all or substantially all of its assets, provided the assignee assumes all obligations under these Terms.

12.5 Subcontractors. Causa Prima may use subcontractors to deliver the Services and remains responsible for their performance under these Terms. Sub-processors that process personal data are governed by the DPA.

12.6 No waiver. Failure or delay in exercising any right under these Terms is not a waiver of that right.

12.7 Severability. If any provision of these Terms is found unenforceable, the remaining provisions remain in effect, and the unenforceable provision is replaced by an enforceable one that comes closest to the Parties' original intent.

12.8 Governing law. These Terms are governed by the laws of the Federal Republic of Germany, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG) and conflict-of-laws rules.

12.9 Jurisdiction. Where the Customer is a merchant (Kaufmann), a legal person under public law or a special fund under public law (§ 38 ZPO), the exclusive place of jurisdiction for all disputes arising out of or in connection with these Terms is Berlin, Germany; otherwise the statutory rules on jurisdiction apply. Causa Prima may also bring proceedings at the Customer's general place of jurisdiction.

12.10 Customer's terms. Conflicting or deviating terms of the Customer (for example, purchasing or vendor terms) do not become part of the agreement unless Causa Prima expressly accepts them in text form.

12.11 Language. These Terms are concluded in English.
