Conflicting provisions (3)
  • Clause A permits immediate termination for incurable material breaches, whereas Clause B implies a universal 30-day cure period for all material breaches before termination, creating conflicting timelines for incurable breaches.

    " Either party may terminate this Agreement immediately for a material breach that cannot be cured, or upon 30 days' prior written notice if curable and not cured within that period. If Client terminates this Agreement for Langfuse’s uncured material breach, Langfuse shall refund any prepaid fees for the unused portion of the applicable Subscription Term following the effective date of termination."
    " 10.3. Termination. Either party may terminate this Agreement (and any active Order Form) upon giving notice in writing to the other party if the non-terminating party commits a material breach of this Agreement and has failed to cure such breach within thirty (30) days following a request in writing from the notifying party to do so. Termination of this Agreement in accordance with the foregoing sentence will automatically terminate any existing Order Forms, and where such termination is rightfully done by Customer for ClickHouse’s uncured material breach, ClickHouse will promptly refund to Customer any prepaid, unused fees. In addition, either party may terminate this Agreement upon written notice to the other party if no Order Form is active under the Agreement."

  • Clause A allows immediate termination for incurable material breaches, whereas Clause B implies a 30-day cure period for all material breaches before termination, which would be contradictory for an incurable breach.

    " Either party may terminate this Agreement immediately for a material breach that cannot be cured, or upon 30 days' prior written notice if curable and not cured within that period. If Client terminates this Agreement for Langfuse’s uncured material breach, Langfuse shall refund any prepaid fees for the unused portion of the applicable Subscription Term following the effective date of termination."

  • Clause A states Langfuse will not materially decrease service functionality or security during the subscription term, while Clause B implies Langfuse may be forced to implement such a material mid-term change for legal or regulatory reasons, offering a client termination right as a remedy.

    " During the Subscription Term, Langfuse will provide the services identified in the Order Form in accordance with the Documentation and if applicable the SLA. Langfuse may update or modify the services from time to time; however, Langfuse will not materially decrease the overall functionality or security of the services provided to Client during the then-current Subscription Term. Public website materials are descriptive and may change; material reductions will follow notice and termination rights."
    " Langfuse may update pricing effective on renewal of the then‑current Subscription term, with at least 30 days' prior notice. Mid‑term changes apply only to (i) add‑ons Client elects, (ii) usage‑based overages per published rates, or (iii) changes in taxes. If Langfuse must implement a material mid‑term change for legal or regulatory reasons, Client may terminate the affected Subscription within 30 days of notice and receive a pro‑rated refund of pre‑paid fees for the terminated portion."

" Only for Clients on an enterprise plan or with an Order Form that includes a Service Level Agreement (a 'SLA'). Langfuse will use commercially reasonable efforts to meet the target availability for core services stated in the Order Form, measured by Langfuse's production monitoring/status records. If the target is not met, Client may request service credits as specified in the Order Form; credits are Client's sole remedy and will not exceed fees for the affected period. Exclusions include scheduled/emergency maintenance, Client/third-party causes, beta/preview features, and force majeure.

Cross-clause notes

Cross-reference

Two verified clauses intersect on the same subject matter: the Terms of Service, § 13 (MISCELLANEOUS) addresses how long content is retained, and the Terms of Service, § 6 (CLIENT DATA) addresses use of content in connection with model training or service improvement. Both clauses are in force at the same time — read them together.

Cross-reference

The Terms of Service, § 11 (TERM AND TERMINATION) describes rights the platform takes in user content, and the Terms of Service, § 4 (CONFIDENTIALITY) describes disclosure of data to third parties or subprocessors. Both clauses are in force at the same time — read them together.
